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.
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.
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.
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.
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
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.
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.

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.
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.
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.
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.
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.
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.
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.
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 is the day many of you have been waiting for. I’ll scope the Walther LGV Master Ultra and test it for accuracy at 25 yards. I used the same Bushnell Banner 6-18X50 AO scope and BKL 260 1-piece high mount that I used on the Walther LGV Challenger in .22 caliber. The scope was already in the mount and ready to install. I thought about removing the sights; but since I couldn’t see them through the scope, I decided to leave them mounted.
One shot at 12 feet told me the scope was adjusted close enough to move back to 25 yards. The first shot at 25 yards then required some more adjustment, and I was ready to begin the test.
With the .22-caliber rifle, I rested the stock on the flat of my open palm with the heel of my hand touching the triggerguard. That gives the rifle a very muzzle-heavy balance and is usually the best way to hold a spring-piston air rifle. But not with this .177.
I had chosen to shoot 7.9-grain Crosman Premier lites as the first pellet because they showed so much promise at 25 yards with open sights. The .177-caliber LGV Master Ultra strung its first 10 shots vertically in a group that measured 0.67 inches between centers. While that isn’t bad, the group was vertical, which can be caused by either loose stock screws or by resting the stock on the off hand at the wrong place.
I checked the screws, and they all did require tightening; but when I shot a second group, it was vertical as well and slightly larger, at 0.819 inches. Obviously, loose stock screws were not causing the problem. Experience then told me to slide my off hand forward until I could feel the back of the cocking slot on my palm.
The second group of 10 Premier lites at 25 yards was also vertical and slightly bigger than the first. And this is after tightening the stock screws. It measures 0.819 inches across the widest centers.
Group 3 was the one I was looking for. Ten shots went into 0.326 inches at 25 yards. That’s 10 shots, not 5. Folks, that demonstrates what I thought was the case — the new Walther LGV is the TX200 of breakbarrel air rifles! Five shots in such a group might have a component of luck with it, but you don’t get lucky 10 times in a row. This rifle wants to put them all in the same place!
So, the best hold is with the off hand out forward, under the back of the cocking slot. That’s going to hold true for all of these Master Ultra models, I think.
Next I tried some H&N Field Target Trophy pellets because reader TwoTalon asked me to. I haven’t had good luck with FTT pellets in springers, but he likes them, though I learned that he’s shooting them only in a PCP. Still, I thought — what the heck?
Ten pellets went into a group that measured 0.683 inches between centers. While that’s not a bad group, it doesn’t look good next to the Premier lite group, so I won’t use it when I move out to 50 yards.
The third pellet I tried was the Beeman Devastator that did so well in the 25-yard open sight test. Again, they proved their superiority by putting 10 pellets into a 0.475-inch group. That’s pretty good for such an open-nosed hollowpoint. The LGV was hot!
JSB Exact Heavy
The last pellet I tested was the 10.34-grain JSB Exact heavy, which did okay in the open-sight test but with qualifications. What “qualifications” means is that I got 8 pellets in a tight group but had two unexplained fliers that opened the group considerably. This time, the results were even more bizarre.
With 10 shots, I got two extremely tight groups…one with 3 shots, and the other with 4 — and 3 wild fliers that don’t belong anywhere. The overall group measured 1.791 inches between centers of the two widest shots. I think what’s happening is that this pellet is very close to what this rifle wants, but it’s still far enough from perfection that it causes wild shots. These pellets fit the bore looser than the other three, which all seemed to fit about the same. The head size is a whopping 4.52mm, so put that into your head-size theories and see what you get. I just don’t know what’s happening, but it’s clear this isn’t a pellet for this rifle.
Wow — what happened? Four pellets went into the small hole at the bottom of the bull, another 3 went into the small hole at the top left and 3 pellets went off by themselves. Total group measures 1.791 inches across the two widest centers.
It’s clear the .177-caliber rifle is pickier about the pellets it likes than the .22, which seems to swallow everything. Find the right pellet, though, and the game is on! The best group with this rifle is roughly half the size of the best .22-caliber group at 25 yards. Fifty yards — here we come!

Let’s see how well the new Walther LGV Challenger performs at 25 yards when the rifle is scoped. For starters, I had to mount a scope. I decided to select a Bushnell Banner 6-18X50 AO scope that I haven’t reported on before. This is a better scope than the Banners of a decade ago, and it performs quite well.
The scope mounts proved problematic, though, because the LGV has a high, rounded spring tube that precludes the use of many scope rings that have a flat base on the bottom. This base high-centers on the rounded spring tube and doesn’t allow the clamping jaws to get into the rifle’s deep dovetails. So, you need to select rings with either generous clearance under their bases, or BKL scope rings that actually are cut away at the base to allow the clamping jaws to clamp harder. I decided to go with the BKLs.
Since the scope has a one-inch tube, I selected the BKL 260 high one-piece mount that fits the rifle perfectly and was quite easy to secure. With the long scope positioned correctly for my eye, there’s still almost 2 inches of room to the breech. I think the LGV’s longer pull makes this happen, as I’m back farther on the stock than I would be with many other rifles.
Sight-in was one shot at 12 feet that landed nearly on target. Then, from 25 yards, the first shot went high and left. In all, it took 5 shots to sight in.
JSB Exact RS
The first pellet I tried was the 13.4-grain JSB Exact RS dome. When shot 2 landed next to the first one, I knew the rifle was going to group. And group it did! Shot after shot went to the same place, no matter how I held it. And that’s not normal for a breakbarrel. Some are more forgiving than others, but this one is the best I’ve seen. More on that in a bit.
Ten shots made a very round group at 25 yards. It measures 0.35 inches between centers and could easily be a PCP group rather than one from a springer.
JSB Exact Jumbo
The second pellet I tried was the 18.1-grain JSB Exact Jumbo that did so well in the test using open sights. This time, the group did not improve. Ten shots went into 0.82 inches at 25 yards, where before the group was 0.78 inches with open sights at the same distance. The group was tall, rather than round, which indicates a velocity variation may have caused the larger group.
I am running short of these Jumbos, though I have them on order. I think I’ll try them at 50 yards, too, in case this group is an anomoly.
The final pellet I tried was the heavy Beeman Kodiak. At 21 grains, this pellet is considered by some to be much too heavy for a 12 foot-pound rifle like the LGV, but I disagree. I don’t think shooting a heavy pellet harms a springer in any way. Ten Kodiaks made a group that measures 0.834 inches between centers; but within that group, 9 of the 10 pellets went into 0.552 inches. The one pellet that landed low and outside the main group was not a called flier.
Ten Beeman Kodoaks landed in 0.834 inches, but 9 of the 10 went into 0.552 inches. That’s a great group! The stray shot was not a called flier.
Impressions so far
I have to tell you, I always cringe when I have to test a breakbarrel for accuracy. That’s because it takes such inordinate skill to shoot one well. It’s like playing a musical instrument. Do it well and everyone is pleased, but they may not be aware of the struggle you went though to make it like that.
Well, this new LGV isn’t like that at all. It’s the easiest-shooting breakbarrel I’ve ever tested. By the time I finished testing it, it felt more like a precharged rifle because of how neutral the hold is. I, therefore, proclaim this Walther LGV to be the TX200 of breakbarrel air rifles. It’s a very forgiving breakbarrel — something that normally doesn’t happen.
Next up will be a test at 50 yards. I know the rifle will be great, and I’m eagerly awaiting the results.

Air Arms S400 MPR FT alert!
Before I start today’s report, I want to make an update to the Air Arms S400 MPR FT blog. Blog reader “coax” asked me to adjust the air transfer port screw to see if I could increase the power of the rifle. Following his instruction to locate that screw, I removed the action from the stock, but I cannot locate the screw he mentions. He says it is located below the loading trough, which I took to mean underneath the loading trough (the bottom of the action) at the rear of the reservoir. Well, there’s nothing to see on the reservoir itself, but on the action just behind the reservoir there is a threaded hole like he describes. The problem is that there is no screw inside that threaded hole. And that is the only threaded hole that I can see.
So there isn’t going to be any power adjustment report on this rifle. If coax wants to send me photos of exactly what he’s referencing, I will look again, but otherwise, the report is completed.
The Air Arms Twice precharged pneumatic air rifle is a dual-reservoir rifle with the air cylinders arranged side-by-side. The rifle has a rollover raised cheekpiece, so it is reasonably ambidextrous, though the bolt stays on the right side.
What is a Twice?
Now, on to today’s report. The Air Arms Twice PCP air rifle will certainly never win any awards for the name! Why they didn’t call it the Double-Up or something — anything — but Twice is beyond me. However, in the spirit of Shakespeare who said, “A rose, by any other name…” we will proceed. (I haven’t forgotten that Pyramyd Air took a survey about other names. Maybe they’ll christen it something else in the near future.)
The name Twice refers to the twin reservoir tubes under the barrel. Obviously, they increase the amount of compressed air the rifle can hold, yet by their design, the rifle is not made substantially taller. Wider, yes, but in the same sense that a double-barreled shotgun is wide. It’s width with elegance.
And, I’m testing serial number 098425, for those who are keeping score. The rifle came to me with a Bushnell Banner 6-18x50AO scope mounted on it. While that’s a good, useable scope, it doesn’t do justice to a premium PCP rifle like the Twice. Since I have the Hawke Sport Optics 4.5-14x42AO Tactical Sidewinder rifle scope on hand, I switched it for the Bushnell. Why not? After all, one doesn’t buy a Ferrari and then fill the tank with 87 octane fuel! A premium rifle deserves a premium scope.
It is a big air rifle!
Let me get this out of the way; because when these rifles start selling, you’re going to read about it on the forums. The Twice is a very large air rifle. Those twin reservoir tubes make it a real handful and that’s that. Also the barrel’s shrouded, which adds to the look of massiveness. The rifle isn’t heavy, at 7.50 lbs., but it is muzzle-heavy. I know there are those who think a muzzle-heavy rifle is a bad thing, but it isn’t if you want to hit things! The extra weight out toward the muzzle slows down the tendency all rifles have to wobble. The Twice hangs right in your hands if you put your off hand just forward of the trigger. My Ballard is very muzzle-heavy, and it doesn’t seem to suffer any.
Of course, this is also a repeater. It features a 10-round magazine that loads the next pellet every time the sidelever pulls the bolt to the rear and shoves it forward again. Having used Air Arms repeaters in the past, I believe this one will be butter-smooth to cock and shoot. I’ll let you know when I test it.
There’s a power-adjustment control on the right side of the receiver, with an index scale on the left side. I will test that function and report my findings during the velocity test.
Here you see the sidelever that operates the bolt. Just in front of the lever handle is the silver power adjustment knob. A scale on the other side of the rifle tells you where the power has been set.
The specs say the Twice is a 20 foot-pound rifle in .177 caliber. Because it’s a pneumatic, it’ll develop the most power with the heaviest pellets…and I’ll be testing it that way. That’s the only way it’ll be the most accurate at long range.
The Twice also will be available in .22 caliber, which I think would be the caliber of choice for a gun in this power range. They rate it at 30 foot-pounds in .22 caliber, and that’s about what I would have guessed. There are so many wonderful new heavyweight pellets in .22 caliber that I would think an owner would want to test them all.
The specs also say you get 180 shots on low power and 60 on high. Unfortunately, a .22 caliber pneumatic will always be more efficient with air than a .177. That number was probably gotten with the larger caliber, but I’ll purposely test this .177 gun at both ends of the power spectrum for you.
The woodwork is nice, but it’s different than the classic look of the TX 200. Only the grip is checkered and the diamonds are sharp, laser-cut and very crisp. The Air Arms logo is also cut into the grip. The butt is scalloped below the cheekpiece on both sides for weight reduction, I presume. That lightens the rifle but increases the muzzle-heaviness.
The stock is finished evenly in a medium brown stain. The reservoir tubes are finished matte, and the shroud is a matching matte finish. The overall look screams “Hunter,” so that’s what I believe the rifle was made to do. With all that air on board, we should see a good shot string at all power levels.
The rifle is an FAC type. FAC stands for Firearm Certificate, which owners will need to own this airgun in the United Kingdom. Once a rifle has been designated FAC, it can never be downgraded to a legal air rifle again, so this will always be an FAC rifle. Because getting an FAC can be quite difficult in the UK, that means the Twice was created for the U.S. market, primarily, because we don’t have the same power restrictions the UK has, except for a couple of states. The United States is also starting to embrace airgun hunting, so I think Air Arms is testing the waters to see if the market is there for them. Certainly, they’ve seen the success of all the AirForce, Beeman, Benjamin, Daystate, Evanix and Weihrauch precharged rifles over here and want to get in on the market. It’ll be interesting to see if the U.S. hunting market can sustain a $1,360 PCP in the face of all the other guns that currently exist. If the Twice can deliver on the promise of power, accuracy, power adjustment and a long shot string, it just might be the best new gun in town. We shall see.
If you like replica airguns for the exquisite realism or to stay proficient with handguns, the Beretta M84FS is made for you! Umarex is the king of replica guns, and this one is a brilliant example of how good it gets. You'll get a thrill every time you pick up your Beretta CO2 gun and pop off a few rounds.
The Stoeger X20S Suppressor is quieter than most other springers of equal power. Get up to 1200 fps in .177 and up to 1000 fps in .22. You'll have the advantage when hunting critters without scaring away the others. It comes with a mounted 4x32 scope. Just 43" long, it's convenient to carry in the field and quickly shoulder when your quarry has been located. Don't hunt? Get it to do some plinking or target shooting without alarming the neighbors.
