EscapeSS
AirForce EscapeSS

If you’re seriously interested in one of the AirForce Escape survival rifles, this blog series should be very beneficial. I’ve tested each rifle and attempted to get the best accuracy possible, using the best pellet. Last time, we looked at the rifle at 50 yards with the Predator Polymag pellet. Today, we’ll look at the EscapeSS accuracy at 50 yards using different pellets with the gun set to higher powers and greater fill pressures. Today’s test was an eye-opener for me.

The day at the range was windy, with a 5 m.p.h. breeze blowing all the time and gusting to 20 m.p.h. I waited for the wind to get as calm as possible, but all shots were in the wind. Sometimes, I took shots with the wind blowing up to 10 m.p.h. I think you can get away with that when shooting a .25-caliber pellet gun, though it’s not ideal.

Predator Polymags at higher power
In Part 2 of the EscapeSS, I shot the rifle at power settings 6 and 7 and with the reservoir filled to 2000 psi and 2200 psi. That was done because testing with both the Escape and the EscapeUL rifles demonstrated that the Predator Polymag pellet was the most accurate. Those rifles also seemed to be most accurate with their reservoirs filled to 2000 psi.

I said at the end of the last test that the Predator Polymag pellet still had to be tested at higher power and with a 3000 psi fill, so that was the first test on this day. I filled the gun’s reservoir to 3000 psi and dialed the power to 8. Then, I shot 5 Predator Polymags.

EscapeSS power 8
The power was set to 8, but as you can tell from the dial on the left, this is not a precision setting.

The results were not very promising. Instead of the 3/4-inch to 1-inch groups I got last time, this time 5 Polymags went into 1.526 inches. While that’s acceptable for hunting at 50 yards, I’d hoped to get better accuracy from this rifle.

EscapeSS Predator target power 8
When the power and pressure were raised, the Predator Polymag pellets started to scatter at 50 yards. Five went into 1.526 inches.

JSB Exact King
For the next group, I wanted to try something that was way out of the box. I filled the reservoir to 3500 psi and left the power setting on 8. That’s more pressure than the factory recommends, but I’ve read some reports from other shooters that say the gun does well with this kind of fill. I wanted to see. This was the first time I was trying JSB Exact Kings in this rifle.

The impact point shifted up about 4 inches, and 5 Kings landed in 1.387 inches. The rifle actually shot better with this pellet at this higher pressure; although, with a 12-inch barrel I doubt that there was much more velocity.

EscapeSS JSB King target 1 power 8
Five JSB Exact Kings went into 1.387 inches at 50 yards on power setting 8 and a fill of 3500 psi.

Having one good target, I decided to try it again with the same setting and fill pressure. This was to see if the first group was a fluke. This time, 5 Kings landed in 1.588 inches, which is close enough to the first group to say this is about what the rifle can and will do with these settings. This time, though, I adjusted the scope to get the pellets on target.

EscapeSS JSB King target 2 power 8
The second try with Kings at a fill of 3500 psi and power 8 gave me this 1.588-inch group.

Now, I decided to follow the manual and fill to just 3000 psi. I left the power setting on 8 — and 5 Kings went into 1.077 inches. Almost a one-inch group!

EscapeSS JSB King target 3 power 8
The fill pressure was lowered to 3000, and the power stayed on 8. Five Kings went into 1.077 inches at 50 yards!

That was so surprising that I filled the rifle to 3000 again and shot a second group, also on power setting 8.  I noted that the shots did drop a bit, so I adjusted the scope again. This time, 5 Kings went into 1.233 inches. So close to the first group that I think this is where the rifle wants to be.

EscapeSS JSB King target 4 power 8
The second try with Kings and a 3000 psi fill on power setting 8 gave me this nice 1.233-inch group. This is a good setting for this pellet.

I also noticed something interesting that illustrates a point I’ve been making for years. The gauge on this particular rifle does not agree with the gauge on my carbon fiber tank. When the tank gauge reads 3000 psi, the rifle’s gauge is off the scale! This illustrates how some small pressure gauges can be off by a lot, which is why you pick one gauge to follow — in this case, the one on my carbon fiber tank — and go by it all the time.

EscapeSS  pressure gauge
When the carbon fiber tank gauge reads 3000 psi, this is what the rifle’s gauge says. This is only on this particular rifle. The other Escape gauges read pretty much the same as the carbon fiber gauge. The point is that small pressure gauges can differ a lot.

Benjamin dome
Now it was time to see what the rifle would do with the Benjamin domed pellet. I kept the power at 8 and the fill at 3000 psi, and 5 pellets went into 1.667 inches. That sort of turned me off after seeing what the Kings could do, so I didn’t shoot a second group. Sometimes, you just know when one pellet is better than another.

EscapeSS Benjamin dome target power 8
Benjamin domes seemed to open up at these power and fill settings. These 5 measure 1.667 inches between centers.

JSB Kings at max power
It was time to try the JSB Exact Kings at maximum power and a 3000 psi fill. I shot 5 of them into a 1.831-inch group. As I was finishing this group, the wind was picking up to the point that I had to shoot in 10 m.p.h. wind and higher. I finished the day with these results:

EscapeSS JSB King target 5 power max
The last target was shot with Kings on a 3000 psi fill and poower set at max. It measures 1.831 inches between centers, but the wind was really picking up when it was shot.

Observations so far
I was surprised that the EscapeSS liked a higher power setting and fill pressure than either the Escape or the EscapeUL. Perhaps, that’s because of the shorter barrel, whose muzzle is so close to the front barrel bushing. I don’t know, but it underlines the need to test these adjustable rifles in many ways and with many pellets.

All 3 Escape rifles are for survival, though they can be used for hunting by anyone. Hunters typically use very few actual shots. The only exception would be when eliminating pests like rats or pigeons. The Escape rifles have small reservoirs that allow easy filling from a hand pump. I’ve found all 3 rifles to be well-suited to their role, but each has different qualities that the shooter may enjoy. With the EscapeSS the big difference is how quiet the rifle is. It’s not as quiet as some PCPs, but it’s also a good deal more powerful than most of them.

I’m still planning to report on the velocities of the 3 Escape rifles at their optimum power settings, so there’s more to come.

EscapeSS
AirForce EscapeSS

Today, we’ll start looking at the accuracy of the AirForce EscapeSS. Unlike other accuracy tests, this one didn’t start at 10 meters or even at 25 yards. I went right out to the rifle range and shot the rifle at the 50-yard backstop.

When you have an air rifle with the power of these Escape rifles, you have to take it outdoors. Unless you have a very special place to shoot, this is an outdoor air rifle.

How loud?
But with that said, the EscapeSS is also the quiet version of the rifle. So, I didn’t wear hearing protection at the outdoor range. I knew the gun wouldn’t be loud enough to hurt my ears, and I wanted to be able to tell you how loud it is. I did not fire the rifle on full power for today’s test, but all the shots sounded very restrained. I would say it was louder than a Benjamin 392 on 8 pump strokes, but not as loud as a Benjamin Discovery in .22 caliber. It’s a sound you can hear, but it isn’t as sharp as a .22 long rifle or even a .22 short.

Experience with AirForce .25-caliber Lothar Walther barrels
To this point in time, I’ve tested the Escape and the EscapeUL — both in .25 caliber. The .25 caliber doesn’t have many accurate pellets, but testing these rifles and the TalonP pistol has revealed a few. One of them stands out as the absolute best. The Predator Polymag pellet in .25 caliber is hands-down the most accurate pellet I’ve tested in these Escape rifles, and my observation agrees with the Escape’s co-developer — Ton Jones.

I cut right to the chase and used the Predator Polymag pellet exclusively in today’s test. I’ll try other pellets in future tests — but, for today, I shot only this one.

Setup
The other experience I have with the Escape rifles is that they’re most accurate with fill levels of 2,000 psi and a power setting of 6. That’s how I set up the rifle for the first group.

I removed the Bushnell Banner 6-18X50 scope from the EscapeUL and mounted it on the EscapeSS in a BKL 1-piece mount and, without even sighting in, I started shooting at 50 yards. I’d planned on sighting in, but my first pellet struck the bull I was aiming at, so there was nothing more to be done. Apparently the EscapeUL and EscapeSS are very similar!

I shot 5-shot groups, because I have found the Escape rifles to be most accurate within a 5-shot band. Sometimes, this will stretch to 6 or even 7 shots, but that’s about all if you’re shooting groups at 50 yards. And I’m shooting groups so small they prove the rifle for hunting purposes! This is not some generalization or extrapolation of accuracy. I’m reporting what these rifles can do in the field.

The first 5 shots went into 1.197 inches at 50 yards. The group was off to the left of the bull, with just the first shot in the black.

EscapeSS first group
First 5 Predator Polymags at 50 yards went into 1.197 inches. This was without sighting-in the rifle — just mounted the scope and started shooting!

With these same settings, the worst group of 5 went into 1.341 inches, and the best 5 went into 0.975 inches. That’s 3 groups that average 1.171 inches. That is about what the rifle does on this setting.

EscapeSS second group
Second 5 Predator Polymags at 50 yards went into 1.341 inches. Of the 3 groups on this setting, this was the worst.

Next, I boosted the fill pressure to 2,200 psi and left the power setting at 6. I got 2 groups — one that was 0.903 inches and the other that was 1.63 inches. That’s a big difference.

EscapeSS third group
Bumping the fill pressure to 2,200 psi and leaving the power set on 6, I put 5 Predator pellets into 0.903 inches — the second-best of this test. But the very next group using the same settings opened up much larger.

Next, the power was increased to 6, and the fill pressure remained at 2,200 psi. I got one group at 1.638 inches, which turned out to be the worst of the test, and a second at 1.077 inches.

I dropped the fill back to 2,000 psi and left the power at 8. This gave a group measuring 1.185 inches.

After that, I dropped the power to 7 with a fill pressure of 2,000 psi. The first group measured 0.778 inches, and the next one measured 1.444 inches. The 0.778-inch group was the best of the entire test.

EscapeSS fourth group
These 5 Predator pellets went into 0.778 inches — the best of this test. That ragged hole at the top is a pellet hole that has partially closed.

Analysis
How do we make sense from these results? It seems the rifle is capable of shooting 5-shot groups smaller than one inch at 50 yards, but the average is slightly larger than one inch. Only one group in this test was as large as 1.50 inches, which I think says a lot about the stability of the .25-caliber Predator Polymag in this rifle.

I didn’t test the other 2 Escape rifles this way, but the results I got with both of them do seem to fit this pattern. It was only because of those results that it was possible to cut through the maze of pellets, pressures and power settings and get these results so fast.

Of course, I haven’t tried this pellet at full power, yet, nor have I tried the rifle with a 3,000 psi fill. I think that has to be tried — just to say that it was done.

The rifle also needs to be tested with other pellets; although, if the groups it gets are similar to those gotten with the other 2 Escape rifles, we may begin to understand that all .25-caliber Lothar Walther barrels perform similarly.

When the other accuracy testing is completed, I’ll test all 3 Escape rifles for their velocities with the most accurate pellets. That would be the information I would want as a hunter.

Evaluation of the EscapeSS
The EscapeSS is closest to the TalonP pistol that sired all three Escape rifles. You would expect the performance to be identical, except that this rifle is both quieter and comes standard with an adjustable buttstock. If you’re looking for quieter performance in a survival air rifle, the EscapeSS might be the one for you.

This report covers:

• Summary of the AirForce Escape report up to this point.
• There are three different air rifles.
• EscapeSS is quieter.
• EscapeSS description.
• How does the EscapeSS differ from the TalonP pistol?
• What comes next?

It’s been a while since we last looked at the AirForce Escape air rifles. To date, we’ve seen the power, accuracy and general characteristics of the AirForce Escape and the EscapeUL, which is the ultra-light version. Today, we’ll start looking at the EscapeSS, which is the version of the rifle with some sound muting.

We’ve seen that the Escape rifles can generate tremendous power — up to 97.88 foot-pounds of muzzle energy from the Escape rifle when the heaviest .25-caliber pellets are used. We’ve also learned that the Escape rifles are at their most accurate when the fill pressure is lowered and the power is dialed back. That held true for both the Escape and the EscapeUL, so it seems to be a trend; and I’ll use that experience when testing the EscapeSS.

There are three rifles!
Before moving on, I want to emphasize there are three different air rifles. The Escape, EscapeUL and EscapeSS all have different specifications and deliver different performance. I’m telling you this because customers are starting to run the model names together and getting confused over which rifle does what.

EscapeSS three rifles
The three Escape rifles are the Escape (top), the EscapeSS (center) and the EscapeUL (bottom).

Each of these air rifles is unique and different from the others. The Escape is the most powerful of the bunch. The EscapeUL is the smallest and lightest, and the EscapeSS that we’re looking at today is the quietest of the three.

If you forget how the first two rifles performed, I urge you to go back to the reports linked above and catch up. I intend reporting on just one rifle in this report — the EscapeSS.

EscapeSS
The EscapeSS is a smaller rifle with a 12-inch barrel inside a frame that acts as a shroud.

Quieter rifle
The SS is the quiet version of the Escape — just like the Talon SS is the quiet Talon and the CondorSS is the quiet Condor.

To achieve this quieter report, the EscapeSS has three baffles ahead of its muzzle. They’re held tight in the frame by a Belleville washer ahead of the last baffle and behind the end cap.

EscapeSS baffles
Inside the EscapeSS shroud/frame are three Delrin baffles and a Belleville washer to keep them from rattling.

I’ve already been to the range and can report that the EscapeSS really is quieter than either the Escape or the EscapeUL. It has the same recoil of the other two, which is greater than the recoil of a medium-weight .22 rimfire rifle, but the sound is greatly reduced.

However — just because the muzzle report is greatly reduced from the Escape does not mean the EscapeSS is a quiet rifle. While it’s much quieter outdoors than a .22 rimfire, it’s also louder than a Benjamin 392 pumped 8 times. The EscapeSS is not for suburban backyards! It’s more of a quieter hunting air rifle for public lands. I doubt it would be noticed beyond a half-mile away.

The EscapeSS description
The EscapeSS is a precharged pneumatic air rifle that comes in both .22 and .25 calibers. It has a 12-inch Lothar Walther barrel; but like all AirForce sporting rifles, it can accept barrels of any length. It can also accept other calibers, but I don’t believe I’d try one in .177 caliber because this powerplant is so overwhelmingly powerful that it would be hamstrung by such a small bore size.

The rifle weighs 4.3 lbs., and its length varies from 27.75-inches to 32.25-inches — depending on how the shoulder stock is adjusted.

The rifle is made on an aircraft aluminum frame that houses all the parts, including the barrel. The 213cc air reservoir can be filled to 3,000 psi, nominally giving about 10 powerful shots. Like all AirForce sporting air rifles, the EscapeSS has adjustable power via an adjustment wheel located on the left side of the frame.

How does the EscapeSS differ from the TalonP pistol?
I have to address this issue before the questions start flooding in. Sharp observation will notice that both the EscapeSS and the TalonP have the same 12-inch barrel (that comes in both .22 and .25 calibers), and they share the identical powerplants. So, what makes them different?

First, the TalonP frame is shorter. This makes the gun smaller, but it also means there’s no room for the baffles. The TalonP is louder than the EscapeSS at the same power.

Next, the TalonP comes without the extendable shoulder stock. You can purchase one as an accessory if you like, but the basic pistol comes without it. The EscapeSS is a rifle that comes standard with the shoulder stock.

The EscapeSS and TalonP should both develop comparable power when they’re set up the same way. But the TalonP is more compact, and the EscapeSS is more of a carbine-length rifle. You have to decide which is best for you. You can always add the shoulder stock to a TalonP, but you cannot make it as quiet as an EscapeSS.

As I said, I’ve already been to the range with the EscapeSS. I used the experience obtained when testing both the Escape and EscapeUL rifles instead of testing every pellet in the rifle. And I knew beforehand that the fill pressure and power settings needed to be lowered, so I started low and worked around until I found the best combination.

EscapeSS power
We know that the EscapeSS has a 12-inch barrel. Knowing how barrel length affects velocity, we know that the velocities for this rifle are going to be lower than for either of the other 2 rifles. But when I tested the rifle, I discovered something I didn’t expect.

All these tests used the 43.3-grain Eun Jin pointed pellet. On high power with a 3,000 psi fill, the first 5 shots gave the following results.

Shot Vel.
1     785
2     776
3     763
4     749
5     739

This gives an average of 763 f.p.s for the first 5 shots. At the end of the shooting, the tank pressure still read 2,500 psi. At the top velocity (shot 1), this pellet produces 59.26 foot-pounds of muzzle energy. At the average velocity, this pellet produces 55.99 foot-pounds.

I then dialed the power setting to 8 and refilled the tank to 3,000 psi. That gave the following results.

Shot Vel.
1     784
2     763
3     759
4     748
5     736

That gives us an average velocity of 756 f.p.s. Not very different, is it? The tank pressure after these 5 shots read 2,400 psi. At the top velocity, the muzzle energy was 59.11 foot-pounds. At the average velocity, the energy was 54.97 foot-pounds.

Then, I dialed down the power to 4 and got a huge surprise. That gave the following results.

Shot Vel.
1     801
2     779
3     767
4     758
5     741

The average velocity for this string was 769 f.p.s. — the highest in the test! At the top velocity, this pellet produced 61.70 foot-pounds of muzzle energy. At the average velocity, it made 56.87 foot-pounds! So, the rifle was more powerful on power setting 4 than it was with the power wheel dialed up as high as it will go. The rifle’s ending tank pressure read 2,500 psi.

The 12-inch barrel is showing up in these results. Clearly the rifle is wasting air with this pellet when the power is set above a certain low number. I think the number is around 4, but it would take more testing to know for sure.

That’s as much velocity testing as I’m going to do now because it isn’t helpful. I’ll come back and do a more thorough velocity test when I know which pellets this gun likes. With this gun, it isn’t just about power. Accuracy is also very important. The best combination of both is what we’re looking for.

In my next report, I’ll show you the results of the first accuracy test, which are very encouraging.

The next step in testing the Escape rifles
After we complete testing the EscapeSS rifle for accuracy, we’ll start the next phase of testing for all 3 rifles. That will be testing their velocity at the most accurate setting with the most accurate pellet or pellets.

Following that, I’ll install a .22-caliber barrel in the Escape and test that. If I see enough difference between the Escape and the Condor, we may do more testing in that caliber, but I don’t know yet. It’s too far into the future to know for sure.

AirForce Condor SS precharged air rifle: Part 7

AirForce Condor SS precharged air rifle with Spin-Loc tank
AirForce Condor SS with Spin-Loc tank.

I bet some of you thought we were finished with the AirForce Condor SS rifle with Spin-Loc tank. Well, we are…in a way. I’m removing the Hi-Flo Spin-Loc tank and replacing it with a standard AirForce tank. Instead of the Hi-Flo valve that gets 20-25 shots per fill, this tank has the standard valve that gives 35-40 good shots per fill. Of course, the power is lower, but it’s still a powerful airgun.

Blog reader Gunfun1 recently asked me to test the Talon SS rifle with all three barrel lengths so he could see the power and velocity increase that the longer barrels bring. I will do that in a future series, but today’s test is different. What we’re testing today is how a Condor powerplant and a .22-caliber 18-inch Lothar Walther barrel performs with the standard tank. The Condor and Condor SS share a common powerplant and air tank — only the barrel lengths differ.

Valvology
Let’s talk about pneumatic valves for a minute to gain a better understanding of what we’re testing. A couple things determine how much power a precharged pneumatic airgun has, and most of them are attributed to the valve. Fundamentally, it comes down to how much compressed air gets through the valve. That’s controlled by two things. The first is the size of the air hole running through the valve. A Hi-Flo valve has a huge hole running though it, so more air gets through each time the valve opens.

AirForce Condor SS Hi-Flo tank and standard tank
The Hi-Flo tank on the left has a larger hole at the end of its valve stem than the standard tank on the right. This is where the extra power comes from.

The second thing that determines how much air gets through a valve is how long it stays open. For a knock-open design like the AirForce valve, the duration the valve remains open is controlled by the length of the valve stem stroke and the strength of the valve return spring (the spring that closes the valve after the shot is fired).

Think of it like this. A hundred thousand people cannot all go through your front door at the same time. The number that can get through depends on how wide the doorway is and how long the door stays open. The moment the door starts to open, people can start coming though; and they’ll continue until the door closes. If a powerful man controls the door, only a few people will get through at a time. If a child controls it, many more will get though each time.

A Hi-Flo valve is like a very large door, while a standard tank is like a regular door. But here is the thing. No matter whether there are a hundred thousand people or two hundred thousand people outside the door (the analog of the air pressure inside the tank), only a certain number will get though each time it opens. And if the number of people outside the door becomes too large, they press against the door and hold it shut. No amount of force can open it then. That’s valve lock.

Barrel length
I’ve said many times that a pneumatic barrel is a lot like the barrel in a black powder gun — the longer the barrel is (within limits): the more time the gas has to push against the pellet, the faster it will exit the muzzle. Bore diameter also figures into this equation. A .177 barrel runs out of steam sooner than a .22 barrel does. The longer barrel is also tied to the caliber. This deserves an explanation.

Imagine 2 funnels. Both have spouts that are 3″ long. One spout is .25″ diameter on the inside, the other spout is 1″ diameter on the inside. Which funnel will empty fastest? The one with the wider spout. That’s because more of the material that passes through the funnel is not in direct (frictional) contact with the walls of the spout. Don’t get confused by what I just said. The larger spout does have more material that’s in contact with the spout; but because the inside diameter of the spout is larger, a much greater amount of material never touches the walls of the spout.

We’ve been testing a .22-caliber Condor SS that has an 18-inch Lothar Walther barrel. As we saw in the earlier tests, this barrel is 6 inches shorter than a regular Condor barrel and produces somewhat less velocity than a standard Condor of the same caliber. We’re now going to install a standard tank that has a smaller valve, so the velocity will drop. That’s one way of looking at it.

The other way to look at this is a standard Talon SS has a 12-inch Lothar Walther barrel. This rifle’s barrel is 6 inches longer. We’re about to see what a longer barrel does with the standard tank. The only difference between today’s rifle and an AirForce Talon (not the SS — the Talon that has an 18-inch barrel) will be the Condor powerplant, which means the weight of the striker. That will add a little velocity because the valve is being opened more forcefully. Going back to the door analogy, it won’t affect things nearly as much as those additional six inches of barrel.

Installing the standard tank
The Condor SS I have is fitted with a Spin-Loc tank. It stays on the rifle all the time and is filled through a male Schraeder nipple. To convert to the standard tank, I’ll remove the Spin-Loc tank with the wrench supplied by AirForce. Then the standard tank will spin on and off for filling, just like it does on my older Talon SS. No tools are required, but of course it does not have a built-in pressure gauge, either. So, I’m back to counting the shots fired; but in today’s test, we’ll see exactly how many good shots there are in this tank at high power.

The test
For the purpose of comparison, I’m going to test the same pellets and the same power settings as were used in the Condor SS test. While those pellets aren’t necessarily correct for this lower-powered rifle, it will give you a basis for comparison between the two tanks, which is all we’re testing here.

Condor SS velocity

AirForce Condor SS velocity data

What we have learned?
There isn’t much adjustability with the Condor SS using the standard tank. I haven’t given you the velocity spreads or the shot count, which are all very close, regardless of the power setting. I actually recorded over 40 shots on power setting 10; so I think I would shoot 40 shots per fill, regardless of where the power was set. The velocity spread varied by pellet, but not so much by power setting. It was about 32 f.p.s. across 40 shots for Eun Jin 28.4-grain domes; 41 f.p.s for 40 Premiers; 25 f.p.s. for 40 JSB Exact Jumbos, except on power setting 4, where it was 17 f.p.s. and 15 f.p.s. for 40 Beeman Kodiaks.

I would set the power on No. 4 for the test rifle because that setting gave more power and velocity than any other setting. You probably want to know why that is. I think the valve opens too forcefully at settings above 4, and it bounces (flutters open and closed rapidly) on the valve seat, costing power. But on setting 4, it doesn’t bounce and thus gets the highest power. Note that setting 2 was always less than setting 4. I believe the valve on setting 2 is not bouncing, but actually opening cleanly, which is why it resembles some of the higher power settings that are bouncing. At least that’s my theory.

The Condor SS is quieter with the standard tank, but it isn’t absolutely quiet. It sounds about like a Talon SS at power setting 10. That’s pleasant, like a loud hand clap. It is quite a bit quieter than with the Hi-Flo tank attached.

Summary
There’s less power when you use the Condor SS with the standard tank, but you just about double the shot count. And the discharge noise is less than that of the gun with the Hi-Flo tank.

What you get when the rifle is set up this way is a Talon that’s a little quieter. The Talon has more adjustability, of course, but today we’ve looked at a way to enjoy more flexibility from your rifle without buying another complete PCP.

If I were to use the standard tank with the Condor SS, I would set it to power level 4 and shoot 40 shots per fill. That would be regardless of which pellet I used.

We’ve already seen the accuracy of this rifle at 25 and 50 yards. Is it necessary for me to do those tests again with the standard tank installed? I think the group sizes will be similar, but of course they’re never quite the same. I’ll let you readers decide.

Yesterday, I shot the AirForce Condor SS rifle with Spin-Loc tank at 50 yards. I’m also going to show you that one surprising group I got last week when I tried shooting the rifle in windy weather. That is a pellet I need to try more often!

The day was not perfect for shooting airguns at 50 yards, but it was calm enough to get the best results. I proved that by shooting some groups when the wind wasn’t calm and they didn’t open at all. We’re talking about a 5 m.p.h. head-on breeze that occasionally dropped to 1 m.p.h. at the lowest, so it wasn’t as bad as it sounds. But when the target is 50 yards away, any breeze can affect the pellets.

I’m going to cut right to the chase in this report. I did try Beeman Kodiak pellets, as well as .22-caliber Crosman Premiers, and neither pellet was worth pursuing. Then, I tried the Air Arms Field Heavy pellet, and knew I’d found the right one. I got good 10-shot groups that had superior smaller groups inside them, but there were always a couple fliers. The power was set to 6 on the power window, and the discharge sound was quite loud, especially considering I was at a rifle range (with my ear protectors off, so I could hear what was really happening).

Ten Air Arms Field Heavy pellets went into 1.968 inches on power setting 6, but 8 of them went into 1.046 inches. That’s good, but why were there fliers?

AirForce Condor SS precharged air rifle with Air Arms Field Heavy pellet power 6-2
This best group of 10 Air Arms pellets on power setting 6 went into 1.254 inches, but 9 of them are in 0.906 inches. Once again, we have a flier.

By this time, I had fired about 40 shots and was starting to understand how this rifle behaves. It seemed to be using too much air at power setting 6 with this pellet, so I dialed it back to power setting 4, and that’s where the magic started. The groups tightened up dramatically, and the fliers stopped altogether. Power setting 4 is where this rifle wants to be with this Air Arms Field Heavy pellet.

AirForce Condor SS precharged air rifle with Air Arms Field Heavy pellet power 4-1
This best group of 10 Air Arms pellets went into 0.873 inches. This was on power setting 4, which seems to be the best setting for this pellet.

Not only did I get better groups at power setting 4, but I also got an astounding 40 good shots per fill. The last 10 shots (shots 31 to 40) did open up just a bit, but even then the group was just 1.172 inches between centers, which is still very good for 10 shots at 50 yards.

AirForce Condor SS precharged air rifle with Air Arms Field Heavy pellet power 4-2
Shots 31-40 on power setting 4 did open up a bit; but these 10 pellets are still in 1.172 inches, and I got 40 shots from one fill.

I’ve a thought about what’s happening. I understand the Talon SS rifle and its 12-inch barrel quite well, and I also understand the Condor and its 24-inch barrel. What I do not yet have is much experience with a Condor valve and tank and an 18-inch barrel. I need more experience with this combination before I’ll be comfortable with the power settings and pellets that work the best. For now, though, the 18-grain Air Arms pellet on power setting 4 is the best in my test rifle.

A wind-bucking pellet
Now, for that pellet that seems to buck the wind better than the rest. It’s a Skenco New Boy Senior 28.6-grain dome. I shot it last week when the wind was higher and it bucked the wind when every other pellet was getting thrown around. My 10-shot group size was a bit large, at 1.704 inches, but 8 of those 10 pellets are in a tight 0.789 inches, and this was in considerable wind! I didn’t have any more of them for today’s test, but I’ll be ordering more for the future, I can assure you.

AirForce Condor SS precharged air rifle with Skenco New Boy Senior pellet 4
On a windy day, 10 Skenco New Boy Senior pellets made a 1.704-inch group, but 8 of them landed in 0.789 inches. This is worth pursuing.

All things considered, the Condor SS performed flawlessly this day. I like the new trigger a lot, and the new safety is the best. I can’t wait to try out this rifle in some novel ways!

We aren’t done with the Condor SS yet. Next, I’m going to switch the Spin-Loc Hi-Flo tank with a standard tank, and we’ll look at the velocity, shot count, noise signature and accuracy at both 25 and 50 yards. By the time I’m finished, you all should know quite a lot about this new air rifle from AirForce.

Before we start today’s report, many of you requested to see the Condor SS next to a regular Condor and a Talon SS for size comparison. The photo below shows that.

Today, we’ll begin the accuracy test of the new .22-caliber AirForce Condor SS rifle with Spin-Loc tank. This was shot indoors at 25 yards and was the first time I’ve shot this rifle for accuracy.

I mounted a Bushnell Banner 6-18X50 AO scope in a one-piece BKL mount with 1-inch rings. The scope was clear and bright at 25 yards. I’ve used it in the past, so I know it’s a good one.

One shot from 12 feet confirmed that the rifle would be on target at 25 yards, so I backed up and shot one more. The vertical adjustment had to be adjusted up about 8 clicks, and I was centered on the target. Now, the shooting could begin.

For this test, the rifle was set on power setting 2, as that had delivered good velocity with all the pellets I would be testing. I didn’t want to waste air; and I was shooting indoors, so there were no breezes to contend with.

Beeman Kodiaks
The first pellet I tried was the Beeman Kodiak that weighs 21.14 grains. The first shot almost destroyed the aim point, but the rest of the shots drifted to the left a little. After 10 shots, I had a 2-hole group that measured a maximum of 0.626 inches between centers. It’s okay, but not what I was hoping for.

Ten Beeman Kodiaks made this group at 25 yards. At 0.626 inches between centers, it’s okay but not what I’d hoped to get from the Condor SS.

JSB Exact Jumbo
After the Kodiaks, I shot 10 JSB Exact Jumbo pellets. They weigh 18.1 grains and are perfectly suited to the power of this rifle. They did give a better, more rounded group; but at 0.613 inches, it wasn’t much smaller than the Kodiak group. I felt the Condor SS should be capable of even better accuracy.

Ten JSB Exact Jumbo pellets did better, at 0.613 inches between centers, but I was still hoping for better from this rifle.

Air Arms Field Heavy
The next pellet I tried was one I’d not shot before. The Air Arms Field Heavy looks a lot like the JSB Exact Jumbo; and at 18 grains, it weighs about the same. But this pellet did much better in the test rifle. Ten of them made a group that measures just 0.328 inches between centers. This very round group was what I was looking for from the Condor SS. It tells me the rifle wants to shoot — I just had to find the right pellet.

Bingo! This is the group I was looking for. Ten Air Arms Field Heavy pellets went into a nice round group measuring just 0.328 inches between centers.

Eun Jin
The last pellet I tested was the Eun Jin 28.4-grain dome. AirForce barrel breeches are specially cut to allow Eun Jin pellets to be loaded more easily than in other PCP rifles, though they still do take a push to seat. But no tools are needed and your thumb doesn’t get sore. And they’re the kind of pellet to use when going after medium-sized game such as woodchucks and raccoons. They made a pleasing 0.577-inch group that’s good for a heavy hunting pellet. It’s a round group, too, so this pellet doesn’t seem to be disturbed on its flight in any way.

Ten Eun Jin domes made this well-rounded group, which measures 0.577 inches between centers.

What’s it like to shoot?
Now that the shooting is done, don’t you want to know what the Condor SS is like? I tested the new trigger and safety last year, but that was on a regular Condor. This is the first Condor SS I’ve had a chance to shoot.

The trigger is light and crisp, but I can hear one of the internal springs tensioning as I take up the slack. That became a sound I heard on every shot. It’s neither good nor bad, just different.

The safety goes off like a stick of butter on a hot pan. There’s almost no resistance. It may look similar to a Garand safety blade, but it’s much smoother and lighter.

The rifle recoils with the shot. Even on power setting 2, there’s a rocket-push to the rear with each shot you fire. It’s not as much as a .22 rimfire, but enough that you know something has happened. I think I like the sensation in a hunting rifle.

What’s next?
Next, we take the Condor SS out to 50 yards and try its accuracy there. We now know the best pellet. Let’s see if that remains the case when the distance doubles.

After that, I plan on installing the standard tank and rerunning the entire test — velocity and accuracy at 25 and 50 yards. With the standard tank, we should see Talon power (greater than the Talon SS) and quiet operation, too. We shall see.

Today, I’ll report the velocities I got with the new AirForce Condor SS rifle with Spin-Loc tank, as well as the shot count per fill and some other interesting things. Yesterday, I spent some time informing you of how the baffled silencer system works in this rifle. Today, that becomes important to understand.

Before we begin, let me clear up some things. Blog reader RidgeRunner thought the reservoir of the Condor SS looked smaller in the photo than the old reservoirs on the other two rifles. It isn’t. It is exactly the same size. The foam that surrounds the tank has changed, and that might give the illusion that new tank is shorter, but that’s just an illusion.

Blog reader Bob from Oz asked for a diagram that shows the flow of air because he was confused by my textual description. That’s where the photo of the silencer parts comes in. The end of the barrel, the true muzzle, is buried deep inside the frame of the rifle. The frame is tubular in front, and many people might think that it looks like a bull barrel, but it’s actually a hollow tube that has an inside diameter of one inch. The baffles fit inside that hollow tube exactly as shown in the photo, except that they are touching each other when they’re installed, so they’re not spread out like they appear in the photo.

When the pellet and compressed air exits the muzzle of the barrel (deep inside the tubular frame of the gun), it passes through the first baffle and much of the air is stripped off. It passes through the open slot of the baffle and is deflected backwards by the wide flange of the next baffle. Then, it passes back through the holes in the front barrel bushing and into the open space between the barrel and frame behind the front bushing.

As the pellet passes through each baffle more of the compressed air gets stripped off and reflected backwards. This all happens in miliseconds and the air is still under pressure, so it eventually comes out the end cap of the rifle.

Why am I telling you this?
You have to understand how this works, or nothing I say will make much sense. The key to quietness is the volume of empty space inside the frame of the gun and the length of time it takes the compressed air to exit the gun. You don’t notice anything, of course. You shoot and hear the report at the instant of firing. But there really is a small lag time, during which the compressed air expands and loses its energy. That energy is what makes the noise, so the greater the expansion, the less noise there is. And the less compressed air that’s used with the shot, the lower the noise will be when everything else remains the same.

First encounter
I told you this because, when I began testing the Condor SS for velocity, I was surprised by the noise. I was testing inside my office, which is 12 by 15 feet, and the last time I heard the rifle was outdoors back in November of last year. I knew this gun I was testing was louder than what I’d heard back then. So, I went to AirForce yesterday and we conducted some tests to determine where the production Condor SS is sound-wise. I’ll get to that after we look at the velocity, so let’s do that right now.

Velocity
Like all the sporting precharged rifles AirForce makes, the Condor SS has adjustable power and interchangable barrels. There’s no way I can test every possible combination of pellets, calibers and power settings, so I selected spots in the power spectrum that I’ll report today. I will report each pellet at all the power settings and give you the shot count for each one.

Eun Jin domes
The first pellet I tested was the Eun Jin 28.4-grain dome. While there are heavier pellets that will generate greater power in .22 caliber, I believe this one will do well in the accuracy test, so it’s a reasonable top-end pellet to test. On the maximum power setting, this pellet averaged 892 f.p.s. I shot it 20 times and the high (shot 3) was 912 f.p.s. The low (shot 20) was 814 f.p.s. Yes, that is a 98 f.p.s. spread; but out to about 35 yards, this pellet will hold zero for those 20 shots. If you plan on shooting at 50 yards and farther, stop at around 10 shots. Your average then climbs into the low 900s and the max spread is less than 30 f.p.s. At the average velocity for the 20 shots, this pellet generates 50.19 foot-pounds of energy at the muzzle.

The power band is more or less a straight declining number from start to finish. Starting at 3,000 psi, you finish at 2,200 psi. A Hill pump then takes about 100 strokes to fill the tank again. So, there are 5 pump strokes per shot on max power.

The rifle was very loud, so I told Edith to change the sound rating in the description to a 4 because this gun is louder than a Sheridan Blue Streak on 8 pumps. It’s quieter than a Condor running at the same power, but still loud enough to notice. In fact, when I was testing the velocity in my office (with the door closed), Edith was in the living room and thought I was shooting a Quackenbush big bore because it was so loud.

Now, let’s look at the performance of the same pellet at different power settings.

On power setting 10, there were 20 total shots at an average of about 878 f.p.s. (48.63 foot-pounds).

On power setting 6, there were 22 shots at an average 868 f.p.s. (47.52 foot-pounds).

On power setting 4, there were 23 shots at an average 858 f.p.s. (46.44 foot-pounds).

On power setting 2, there were 25 shots at an average 830 f.p.s. (43.45 foot-pounds)

The power spreads from the first shot to the last were closing up as the power was dialed down; but even at setting 2, there was still 80 f.p.s. variation, start to finish. The beginning and ending air pressure was always the same for each string. Even on the lowest power the rifle sounded just as loud.

Crosman Premiers
Then, I tried the Crosman Premier pellet that weighs 14.3 grains. The Condor was the first air rifle to get this pellet supersonic in .22 caliber. In the Condor SS, the average on high power was 1076 f.p.s. It ranged from a low of 1029 f.p.s. to a high of 1117 f.p.s., so, once again, a large spread. At the average velocity, this pellet generates 36.77 foot-pounds of energy at the muzzle. And there were the same 20 shots per fill, with the same starting and ending air pressures. There was no noticeable difference in the report between this pellet and the Eun Jin.

On power setting 10, there were 20 shots at an average of about 1067 f.p.s. (36.16 foot-pounds).

On power setting 6, there were 22 shots at an average 1062 f.p.s. (35.82 foot-pounds).

On power setting 4, there were 23 shots at an average 1033 f.p.s. (33.89 foot-pounds).

On power setting 2, there were 25 shots at an average 1010 f.p.s. (33.70 foot-pounds)

As with the heavy pellets, the power spreads were closing up as the power declined; but even at setting 2, they were still 60 f.p.s. from start to finish. The beginning and ending air pressure was always the same for each string. Even on the lowest power, the rifle sounded just as loud.

JSB Exact Heavys
Next, I tried the 18.1-grain JSB Exact Heavys. I expect this pellet to be matched well to the power of this new rifle. On maximum power, they averaged 1004 f.p.s., which generates 40.52 foot-pounds of muzzle energy. The high was 1059 f.p.s., and shot 20 was 962 f.p.s. I still got 20 shots per fill, and the muzzle report was identical to the others.

On power setting 10, there were 20 shots at an average of about 988 f.p.s. (39.24 foot-pounds).

On power setting 6, there were 22 shots at an average 981 f.p.s. (38.69 foot-pounds).

On power setting 4, there were 23 shots at an average 970 f.p.s. (37.82 foot-pounds).

On power setting 2, there were 25 shots at an average 966 f.p.s. (37.51 foot-pounds)

Notice that these pellets seemed to do very well on the lower power settings. That is important because the shot count increases with very little loss of power. The total velocity spread on setting 2 was 69 f.p.s. I think this may be the best pellet for this rifle, but accuracy testing will have to prove it.

Beeman Kodiaks
The last pellet I tested was the Beeman Kodiak that weighs 21.1 grains in .22 caliber. Many will select this pellet for a powerful rifle like the Condor SS. On the maximum power setting, these pellets averaged 970 f.p.s. The high was 1017 f.p.s. The low was 908 f.p.s. Like the other 3 pellets tested, a large velocity spread over the 20 shots; but as I pointed out before, out to 35 yards it won’t make much difference. At the average velocity, this pellet generated 44.09 foot-pounds of energy at the muzzle.

On power setting 10, there were 20 shots at an average of about 965 f.p.s. (43.64 foot-pounds).

On power setting 6, there were 22 shots at an average 952 f.p.s. (42.47 foot-pounds).

On power setting 4, there were 23 shots at an average 936 f.p.s. (41.06 foot-pounds).

On power setting 2, there were 25 shots at an average 920 f.p.s. (39.67 foot-pounds)

Summary of power performance
The Condor SS I’m testing seems to work best at power setting between 4 and 10, with the lower setting being better. The shot count increases, and the velocity spread gets a little tighter, plus not much power is lost. Let’s keep that in mind, and I’ll get back to it in a moment.

Sound testing at AirForce
I took my rifle out to AirForce Airguns and tested it against a production gun, another gun that had a pre-production prototype barrel and a .22-caliber Benjamin Marauder. I had said in Part 1 of this report that the Condor SS set on maximum power was no louder than the Benjamin Marauder when I saw it shoot last November. The one I now have for testing certainly seems to be louder.

We shot outdoors but next to the steel building, so there was some sound reflection from the building walls. Clearly, my Condor SS is just as loud as the current production gun, and both are louder than the Benjamin Marauder dialed up to its maximum power. But here’s the difference. The Benjamin Marauder shot Beeman Kodiaks between 801 f.p.s. and 828 f.p.s., and both Condor SS rifles shot the same pellet at an average 920 f.p.s. when set on power setting 2. So the Condor SS is putting out about 40 foot-pounds when dialed down low, and the Marauder is putting out around 30 foot-pounds with the same pellet when it’s adjusted as high as it will go. That’s a big difference.

So, why was the Condor SS I had heard back in November so much quieter than this one? Well, for starters, back then the baffles had smaller holes through them. Now, they’re able to safely handle calibers .20 through .25; but back then, they were still experimenting with the hole size. Also, the barrel in my test rifle is 16mm diameter. The prototype rifle had used a 12mm diameter barrel; so AirForce installed a 12mm diameter barrel in their production rifle that we tested yesterday, and the sound went down a little. The 12mm barrels are being processed now for production.

Then, we installed a standard SS tank on the Condor SS that now had the 12mm barrel and dialed the power down to 838 f.p.s. with the Beeman Kodiak pellets. That was as low as we were able to go when the 3,000 psi fill was fresh. Now, the Condor SS was only a little louder than the Marauder that was shooting just a little slower. We shot them side by side several times to make sure. There’s a difference you can discern when testing side by side, but outdoors it isn’t that great.

Remember, this is shooting outside but close to a building, and the standard tank is being used instead of the High-Flo tank that comes with the rifle. You can buy a standard tank as an accessory, but they aren’t going to sell one with the rifle instead of the High-Flo tank, so don’t even ask!

As far as the Spin-Loc tanks are concerned, they’re the new design. Pyramyd Air has opted to phase out the version with the old-syle quick-detach tank and stock only the versions with the Spin-Loc tank. The quick-detach tank that screws in is also available as an accessory in both the standard and High-Flo configurations.

Observations so far
Wow! This has to be one of the longest reports I’ve ever written. And the first part of it was yesterday, in Part 3. I hope this addresses your concerns about this rifle, and that you now clearly understand what you’ll receive when you order a Condor SS. It’s quiet for the power it generates, but it’s not whisper quiet like I originally said.

There’s still so much ground to cover with this test rifle. Accuracy testing comes next at 25 yards and then 50 yards. And after that, I’ll install a standard tank and do today’s test again. Stay tuned!
