Today, we’ll look at the accuracy of the new .25-caliber AirForce EscapeUL. This is the ultra-lightweight version of the Escape rifle and has most of the Escape’s power but is more than a pound lighter. The Escape is already lightweight, but at just 4.25 lbs., the EscapeUL is a real featherweight.
The day I chose to test this rifle was very cold, with a threatening breeze that soon picked up to a 20 m.p.h. wind. I did all of my shooting between puffs and gusts.
Because this rifle is so potentially powerful, I decided to test it all-out with the first 2 pellets. The power adjuster was run up as high as it would go and the tank was filled to 3,000 psi. The first pellet I tested was the heavyweight 43.2-grain Eun Jin pointed pellet. As you’ll recall from my tests of the Escape, I’m shooting 5-shot groups instead of 10-shot groups because the velocity decreases with every shot. At 50 yards, I can keep 5 shots in a good group, but trying to do that for 10 in a row opens things up. There are still 10 good shots on a fill, but you have to change your aim point to use all of them.
The first group measured 1.866 inches between centers. That’s with a pellet that produces from 70 to 80 percent of the power of a .22 long rifle bullet, so it’s plenty potent. The Eun Jin pellets are not the most accurate in these rifles; but for power on target, they’re pretty hard to beat.
Next, I refilled the rifle and tried the same thing with the 35.8-grain Eun Jin dome. This time the group opened to 2.506 inches between centers. In light of the heavier pointed pellet’s accuracy, I don’t think I would use this pellet in this rifle.
Experience comes in handy
I’ve said many times that a shooter can adjust these AirForce rifles so much that you’ll never be able to test everything; but, fortunately, there’s a better way if you have some experience to go on. And I did have some experience because I’d already tested the Escape rifle. While it does have 6 inches less barrel and a thinner barrel to boot, the rest of the EscapeUL is pretty much the same as the Escape. I felt that if I went in the direction that gave some success with the Escape, it might work with this rifle, as well.
JSB Exact King
I knew that the Lothar Walther barrels in AirForce rifles like JSB pellets, and in .25 caliber the JSB Exact King pellet is a real performer. When I tested the TalonP pistol, the King was one of the best pellets, and you know the Escape rifles are all based on the TalonP platform.
I also knew that I should reduce both the starting air pressure in the tank and the power setting to do well with the King. But I wanted to see if it could handle the full 3,000 psi; so, the tank was filled to the max, but the power setting was dialed back to setting 8. I started shooting and was so successful that I kept right on after the fifth shot. Eight shots went into 1.61 inches at 50 yards. I would have shot another 2 shots but this time the air pressure had dropped to 2,000 psi on the built-in gauge, and I thought the next shot might go somewhere else.
Next, I tried the Kings with the same power setting (8) and a starting air pressure of 2,600 psi. I shot just 5 pellets that went into 1.209 inches at 50 yards. That was definitely the best the rifle had done to this point, but I’d seen even better accuracy from the Escape, so I decided to shoot these pellets again.
A second group of Kings with the same fill pressure and power settings produced a 1.526-inch group. That was still good, but I felt the rifle could do even better. It was time to switch pellets.
Ton Jones has done more testing than I with these rifles, and he likes the Predator Polymag pellet the best. Even when he knows the Eun Jin pointed pellet produces more energy, he trusts the Predator Polymag to go where he shoots. That was the next pellet for me. I filled the tank to just 2,500 psi and set the power at 6.
I expected a good group, but I wasn’t prepared for how good! Five Polymags went into 0.622 inches at 50 yards. Despite the cold (20 degrees F) and the winds that were gusting to 20 m.p.h., this hollowpoint pellet was drilling them in!
Predator calls their Polymag a pointed pellet, but I call it a hollowpoint. The point is just a plastic tip that’s glued in place. The pellet acts like a hollowpoint on game, so I call it one regardless of the plastic tip. Just a little quirk of mine, I guess.
That first group was stunning. By now, the wind was blowing all the time, and my day with air rifles had ended. I did shoot a final group of Polymags in the wind, waiting out the gusts and shooting when the wind was down to about 5-10 m.p.h. The same setting and fill pressure was used. This time, 5 pellets landed in 1.298 inches at 50 yards, and I can truthfully say it was the wind’s fault. However, this group is still the third best of the day, which says a lot for the Predators in a reasonable wind. I think Ton is right — this is the best pellet for the Escape rifles, but you have to lower the power and fill pressure.
More to do
As with the Escape rifle, I’m not done with the test just yet. I need to get the velocity figures for the best pellets, power settings and fill pressures so we have some idea what this rifle can reasonably do in the field. Before I do that, I want to try the EscapeSS first.
Summary so far
Most shooters will look at the Escape’s raw power and choose it over the EscapeUL on that basis, alone. But I look at the light weight, compact size and the stunning accuracy of the EscapeUL and think it would be my pick, so far. From the standpoint of muzzle report and recoil, there’s very little difference in these 2 rifles. Both are loud and both kick like a rimfire rifle — perhaps even more. But there’s still one more rifle to test.

I’m testing 3 AirForce guns together — the Escape, the EscapeUL and the EscapeSS. All 3 are based on the same powerplant that is derived from the TalonP pistol. That’s why I am grouping them together like this. But each rifle has its own unique characteristics, too. And this is our look at the EscapeUL, which is the ultralight version of the rifle. It’s the lightest of the 3 air rifles and comes in either .22 or .25 caliber. I’m testing a .25.
As you will remember, the Escape is a collaboration between AirForce Airguns and Ton Jones, the star of television’s Auction Hunters. Ton had the requirement for a survival airgun and came up with the idea of putting a longer barrel on the TalonP pistol action, and AirForce did the engineering and development that turned it into a production rifle.
What does survival mean?
Survival is a word that’s charged with emotion, so the definition depends on the person who is using it. For many people, the term connotes a human wave attack with bullets and missiles flying everywhere — a last stand at the Alamo. But is that what survival really means? If you’re in the Alamo at that moment, I guess you would agree with that definition, but most of us will thankfully never be in that situation. But every year, millions of people are thrust into real survival situations.
Hurricane Sandy, a force 5 tornado, a blizzard that won’t stop or just having your truck break down 20 miles off Old Lincoln Highway outside Ely, Nevada, in the late summertime can all qualify as survival situations. Maybe all you have to do is hold out for 2 days before someone comes looking for you. You were exploring an old ghost town, and now they want to add you to the town rolls!
You don’t need a track-mounted machine gun or a Patriot missile launcher, but it sure would be nice to know you could defend yourself if a wild dog showed up! Or, if you had some way of popping one of those elusive prairie chickens that run along the ground and seem to stay just outside throwing distance. So, in your truck, along with the extra water, gasoline, MREs and sleeping bag (with cot, for this is the desert) you have a small canvas bag. Inside is a scoped EscapeUL, a hand pump and a tin of pellets. The rifle has been sighted-in, but you check it with one shot at an MRE wrapper stuck on a creosote bush 40 yards away — just to be sure. Then lay the rifle on top of the bag on the ground and put 10 pump strokes back in — 7 to get the air line up to pressure and 3 for the shot you just fired — and everything is good to go. The bag weighs 12 lbs., total, and has straps for shoulder carry. That’s what we mean by a survival airgun.
We took a good look at the Escape rifle for both power and accuracy and found that it can be plenty accurate when you use the right combination of pellets and pressures. Ton has pronounced it good to go, and his logo is on every Escape made.
The EscapeUL, however, is an AirForce idea. Ton knows about it and did test it, but it doesn’t bear his logo. It has slightly different features for a person with slightly different needs.
The EscapeUL is designed to remove all unnecessary weight from the rifle, while retaining as much of the power as possible. It has an 18-inch barrel instead of the Escape’s 24-inch barrel, so some velocity is lost. We’ll see how much in a moment.
The barrel isn’t just shorter, it is also thinner. Instead of a nominal 16mm diameter for the Escape barrel, the UL barrel is just 12mm. That diameter is only nominal. Some comes off when the barrel is ground before bluing. The barrel on my test rifle measures 0.477 inches across, which translates to 12.1158mm.
The net weight of the EscapeUL is 4.25 lbs., making it several pounds less than most precharged rifles and even less than some of the lightest ones.
Of course, we all want to know what a thinner barrel means as far as accuracy goes. That test will be next. But now, let’s take a look at power.
The EscapeUL shares the same 213cc Spin-Loc air reservoir as the Escape and TalonP pistol, so the number of shots per fill is going to be about the same. Physics being what they are, we already know what to expect. The powerplant is also the same. The same valve in the tank and same striker weight and spring tension will give similar performance. It’s the 18-inch barrel that makes the difference.
With the heaviest .25-caliber pellet, which is the Eun Jin pointed pellet that weighs 43.2 grains, the maximum velocity in the 18-inch barrel is about 910 f.p.s. The 24-inch Escape barrel gave a maximum of 1010 f.p.s. with the same pellet, so the UL barrel loses about 100 f.p.s. In term of muzzle energy, that’s 79.46 foot-pounds on the first shot, compared to the 97.88 foot-pounds for the Escape.
As with the Escape, the velocity drops with each succeeding shot. By shot 5, the velocity will be down to 855 f.p.s. That carries an energy of 70.14 foot-pounds.
In .22 caliber, the energies are all lower because the pellets are lighter. With a 28.4-grain Eun Jin dome the maximum velocity is 980 f.p.s. on the first shot. That’s 60.58 foot-pounds of muzzle energy. By shot 5, the pellet leaves the muzzle at 900 f.p.s. and generates 51.09 foot-pounds.
You can discuss their performance in several different ways; but to my way of thinking, the Escape rifles are best in .25 caliber. I’m glad that’s the way I will be testing this one.
The trigger, adjustable stock, automatic safety and scope mounts are identical to those found on the Escape. It’s plenty for a scope, scope level, tactical flashlight and laser. There’s even enough for a coffee grinder, if you can find one that will fit!
I’ve already been asked if the Escape rifles will run on CO2. They should, but it will need to be tested to say for sure. Since they were not designed to operate on CO2, I’ll have to find a way of filling the reservoir. No CO2 coupling I know of will mate with an air coupling, so it may take me some time to work it out.
I’ve also been asked on the back channel how quiet these airguns can be. Quite frankly, I don’t know. Given all the technology in the world, they can probably be made quieter than a Marauder; but once I answer that, the next question will be if all that technology can be reduced in size to fit in a pocket! We criticize the U.S. Air Force for asking that everything be made from unobtainium (strongest metal known whose forms weigh nothing and add lift to airframes), yet we do the same thing when it comes to powerful airguns. “Great,” we say, “but can they also be quiet and get lots of shots, too?”
There’s survival and then there’s daydreaming. We’re talking survival here.

Last time we looked at the accuracy of the AirForce Escape at 50 yards. I shot the rifle on low pressure and a low power setting on that day to see what it could do. You may remember that at 50 yards, I got a best 5-shot group with JSB Exact King pellets that measured 0.594 inches between centers. That’s great for a .25-caliber PCP, but I know it left some of you wondering what the rifle can do at its maximum power. Today, we’ll look at that.
The heaviest .25-caliber pellet I have is the Eun Jin pointed pellet, which weighs 43.2 grains. So, it’s a little heavier than the standard bullet of a .22 Long Rifle cartridge. We know from testing that this pellet leaves the muzzle at up to 1010 f.p.s., generating 97.88 foot-pounds of energy.
I also had some Eun Jin domed pellets to test. At 35.8 grains, they’re lighter than the pointed pellet but might be accurate enough to make a difference. As long as I’m testing, I thought why not test them, too?
The wind had just started to pick up at the range. I had finished testing the Benjamin Marauder with synthetic stock and shifted to the Escape because I felt the power of the gun and weight of the pellet wouldn’t be affected by this wind nearly as much as a smaller pellet moving at lower speed.
The first thing I tried was the heavy Eun Jin pellet on max power and with a max power setting on the gun. The first 2 pellets went through the same holes at 50 yards, and I thought I was on to something. Then, shots 3 and 4 moved 2 inches to the right but also landed in a single hole. Shot 5 then landed an inch to the left of the first 2 shots, giving me a 5-shot group that measures 2.478 inches across the widest centers. While that is adequate accuracy for larger animals at 50 yards, it wasn’t as good as I’d hoped it would be.
Five Eun Jin pointed pellets on maximum power with a 3,000 psi fill at 50 yards. The group measures 2.478 inches between centers, but look how they landed. The first two are left of the pellet, the next 2 are to the right of the dime (in the same hole) and pellet 5 is all the way over to the left.
I remembered that there are 10 good shots on a fill of the Escape’s small 213cc reservoir, so I shot the next 5 pellets at a different target. The scope wasn’t adjusted. The reservoir pressure at the start of this string was about 2,600 psi. This time ,all 5 went into 1.622 inches. That’s a significant improvement. According to the velocity test data, these shots ranged between about 71 and 82 foot-pounds.
I was satisfied with the results of this heaviest pellet, but I’ve never gotten the best accuracy with pointed pellets. I felt I might be at the limit of this pellet’s performance. Time was passing and the wind was building, so I moved on.
The lighter domed pellet remained to be tested. On max power with a 3,000 psi fill, I got several open 5-shot groups that all hovered around 2 inches. While that’s okay, it isn’t what I wanted. Then, I shot a couple groups with the power set to max and the starting air pressure set at 2,600 psi. The only reason I did it that way was because of the results of the heavier pointed pellet I’d just tested. And that’s where the magic happened!
The first 5-shot group on this setting (power set on max, starting fill pressure at 2,600 psi and shooting the 35.8-grain domed Eun Jin) measures 1.177 inches. Four of those shots are in 0.555 inches! That’s fantastic! I don’t have the velocity data for this pellet on that setting, but I’ll venture a guess it’s producing around 60-70 foot-pounds.
Like you, I wondered if this single group was just a fluke, so I filled the reservoir to 2,600 psi, again, and shot a second group. This time, I put 5 into 1.089 inches. Three of those pellets are in 0.214 inches. If you overlay those 3 pellets on top of the other group, they all go to the same place!
Here’s the miracle I was talking about. Same starting air pressure, and 5 pellets went into 1.089 inches. Three of them are in 0.214 inches and in the same place as the 4 pellets from the last group. This is significant!
What I’m saying is that somewhere around this power setting and fill pressure, there’s a super sweet spot the Escape loves with this domed pellet. By spending more time refining the fill pressure and by adjusting the sights for this combination, the Escape will become a tackdriver. It doesn’t get a lot of shots like this, but remember — this is a survival rifle. You want one shot — one kill. I think this gives that to you!
I could continue to refine my pressure settings with this pellet, but I don’t think I have to. I’ve now shown you 2 different ways the AirForce Escape can make very small groups at 50 yards. If you’re looking for a powerful air rifle to do some serious hunting, you should consider this one. I think Ton Jones and John McCaslin both have reason to be proud of their creation.
I was prepared to exchange barrels at this point and try the .22-caliber Escape, but I think I’ll let that slide for now. If I’m any judge, most buyers are going to get the .25-caliber Escape. Once they see these results, I expect they’ll do similar tests. Therefore, I plan to switch over to the EscapeUL next. That’s the ultralight rifle that has an 18-inch barrel. I’ll give you a combined introduction and velocity/power report, followed by a range test like this.

Tarzan! This weekend, a number of readers conducted a discussion of the fictional character Tarzan and the author who created him, Edgar Rice Burroughs. I thought you should all know an interesting connection of Tarzan to airguns. His grandson, J.R. Burroughs, was a big-time airgun importer in the 1990s. In fact, he imported many of the Korean brands that are still coming in today.
When I started writing about airguns in 1994, I got to know J.R. through my writing, and I eventually met him at one of the SHOT Shows. We continued to communicate about airguns and many other things well into the 21st century. I haven’t heard from him since I got sick back in 2010, so he may no longer be involved with airguns like he once was, but he was certainly a mover and shaker in the U.S. airgun scene during the time he was active.
A couple points of interest with J.R. He was the man who modified the Shinsung Career 707 adjustment wheel from 3 settings to 17 settings — giving us much greater control over the velocity of our rifles. The factory eventually made the same modification. It was possible to keep a Career shooting at the same velocity for a long time simply by adjusting the power wheel as you shot. I remember testing it over a chronograph and getting 90 shots that were all within 30 f.p.s.
J.R. also created the first adjustable trigger for the Career, and I believe he also created one of the first pellet feed mechanisms that was user-adjustable. Before that, you could only shoot a few types of pellets in the gun; but with his modification, many more types of pellets would work through the magazine.
His brother, Danton manages, the licensing of the Burroughs family literary property. Part of that is a collection of original Tarzan novels that were never sold. There was a fire in the storeroom many years ago and some of these books have smoke damage, but they’re all like-new hardcover books from the 1930s. I was gifted with one — Tarzan and the Forbidden City — from this collection, and J.R inscribed it, saying that his father had done the cover art.
Of course, many of you know that the southern California community of Tarzana was created from Edgar Rice Burroughs’ Tarzana Ranch in the San Fernando Valley. But how many know that Tarzana was also the name of small hamlet located on the ranch before Burroughs purchased it? And his Tarzan character appeared in print for the first time two years after he bought the ranch.
So, Tarzan does have ties to modern airgunning. I thought you would like to know that. One final thing. Burroughs didn’t just write adventure novels. He is also quite famous for his science fiction that bears a remarkable resemblance to his other works, but are set on Mars. Edith and I both enjoy the movie John Carter, in which Burroughs appears as a minor character who turns out to be the author who documents the “real-life” exploits of his uncle, John Carter. I think we enjoy it most because of our fond memories of J.R.
Now, let’s take our first serious look at the new AirForce Escape survival rifle. Before I start, I need to make a couple corrections to Part 1. I said the Escape SS (officially named the EscapeSS) has an 18-inch barrel and several readers figured out that wasn’t the case. It actually comes with a 12-inch barrel in either .22 or .25 caliber.
I also said the Escape valve is a modified TalonP pistol valve, which isn’t true. The TalonP valve is used exactly as it is in the pistol, so pistol owners who add a 24-inch barrel and end cap to their pistols can essentially have the Escape. The pistol’s frame is shorter than the Escape frame, but it is just right for the Escape Ultra Light (officially named the EscapeUL) that we’ll look at in a later report.
The Escape rifle looks like the other AirForce sporting rifles and has many of the same features. The new trigger is there, along with the new safety that can be taken off safe by the trigger finger, alone. The 2-stage trigger on my rifle breaks at a relatively clean 28 oz. While it’s not adjustable, I think most serious shooters will find it more than adequate.
The rifle weighs 5.3 lbs. unscoped and measures from 34.5 to 39 inches long, depending on where the extendible buttstock is set. That means the length of pull can also be varied from 9.75 to 14.25 inches.
Like all other AirForce rifles, the Esacpe has long 11mm rails on top and below the receiver. Since this is a survival gun, a bipod and sling swivels might be almost as important as a scope.
I tested this rifle differently than normal. Instead of getting the chronograph figures right away, I decided to shoot it at the range, so 2 days were spent on the range with the rifle in its .25-caliber incarnation. Once I have a good baseline of performance downrange, I’ll come back and chrono the best pellets, pressures and power settings. Because these rifles are so infinitely adjustable, it makes sense to figure out what works before you worry about the numbers.
But I’ll give you some velocity figures because Ton Jones tested the heck out of the rifle late last year, and AirForce provided me with the data. With .25-caliber JSB Exact King pellets and the rifle set to max power, Ton’s first shot was 1145 f.p.s. The first 10 shots on a 3,000 psi fill looked like this:
On power setting 8, the same pellet did this on the first 10 shots after a 3,000 psi fill:
On power setting 4, the same pellet did this on the first 10 shots after a 3,000 psi fill:
At max power and the highest velocity, this JSB pellet generated 73.96 foot pounds of energy at the muzzle.
With the 43.2-grain Eun Jin pointed pellet, the rifle did this on the first 10 shots at max power after a 3,000 psi fill:
On 8 power with a 3,000 psi fill, the rifle did this with the Eun Jin:
On 4 power with a 3,000 psi fill, the rifle did this with the Eun Jin:
At the max power setting and highest velocity, this pellet generated 97.88 foot-pounds of energy at the muzzle.
I have the data on the Escape’s .22-caliber performance, but that will make today’s report too large, so let me continue with just the .25-caliber rifle, which is how AirForce set it up for me. I took it to the rifle range on 2 different days. Both were cold but the first one was also very windy, so I’m going to show you the results of day 2 testing, only. The day was 16 degrees F (-9 C) but dead calm. I shot several types of pellets this day and based on those velocity figures you have just seen, I decided to shoot 5-shot groups instead of 10-shot groups.
Ton Jones maintains that a survival situation calls for a single well-placed shot, rather than a number of shots fired rapidly. I agree with him, so I’m not testing the Escape as I normally would. I fired 5 shots and then topped off the air tank. When you’re making single shots, that makes sense.
On max power the best groups I shot were with JSB Exact King pellets and Predator Polymag pellets. At 50 yards, 5 JSB Kings went into a group that measured 1.846 inches between centers. That’s a large group, but remember that you’re shooting at large targets, and 50 yards may be farther than you choose to shoot.
Predator Polymags put five into 1.819 inches at the same 50 yards on max. power. Notice that both pellets spread their shots horizontally.
Experience takes over
I’m not going to bore you with each and every experiment I did on this day, but I want you to know that I also tried Benjamin domed pellets and Beeman Kodiak pellets. Both gave similar results, with the Kodiaks doing slightly better than the Benjamins.
But I knew that this rifle was more accurate than this. From my experience with other powerful precharged rifles, plus the testing I did with the TalonP pistol, I reckoned the fill pressure had to be lowered and the power adjusted. It soon became obvious this was correct and the JSB Exact King pellet was the one to go with. After several more groups, I settled on a fill of just under 2,000 psi and a power setting of 6. The groups became amazing with this combination, plus they were remarkably uniform from group to group.
Now that I know where at least one sweet spot is located, that will be what I’ll test through a chronograph. I’ll guess that this pellet is producing something in the 30 foot-pound range with the settings I used. Hitting the target with that kind of energy is much more meaningful than missing with three times more.
I also haven’t tested the heavy Eun Jin pellet for accuracy. And Ton told me that he lubricated his pellets with Slip 2000, which I’ve obtained, so I’ll be able to replicate what he did.
How do I summarize anything when I’ve only just started to test the rifle? There’s enough variability here that I could spend the rest of my life just testing the Escape in .25 caliber! What I can tell you is that the rifle performs as advertised, and, yes, you do have to work with it to get these kinds of results. AirForce has always made air rifles for the thinking man, and the new Escape continues that tradition proudly.

We’re back to the BSA Scorpion 1200 SE. When we last tested it, we looked at the velocity and discovered this is a 30 foot-pound air rifle. So, its primary purpose is hunting. I thought that meant I should test some heavy .22-caliber pellets, but I also included a middleweight.
This test was done at 50 yards. I never shot the Scorpion indoors at 25 yards because it’s so loud. I went straight from mounting a scope to shooting at 50 yards. As it turned out, that cost me several more shots than normal to get on paper.
I scoped the rifle with the UTG 6-24X56 AP scope with illuminated reticle.
I knew the scope would be right for the Scorpion because BSA PCPs are very accurate. I wanted a lot of power in the scope to compliment the long-range capability. This scope gave me what I was looking for.
The first pellet I tried was the 21-grain Beeman Kodiak. The first group wasn’t good because the wind kicked up just as I fired a couple of the shots. Sure enough, the 10 holes had a horizontal spread. They measure 1.006 inches between centers, which isn’t bad, but I felt this pellet deserved a second chance.
The second group of 10 Kodiaks measures 0.926 inches between centers. Although that isn’t that much smaller than the first group, this group is rounder; and I feel it’s representative of what Kodiaks will do in this rifle.
Eun Jin dome
I said during the velocity testing that the 28.4-grain Eun Jin dome would probably be good if you were seeking the maximum knockdown power at long range. They developed an additional foot-pound of muzzle energy. They’ve never been the most accurate pellets, but in some PCP rifles they do deliver credible accuracy.
Not in the Scorpion 1200 SE, though. The Eun Jin gave a large groups with a pronounced vertical spread. It measures 1.488 inches between centers and was the largest group of the test. I don’t recommend this pellet in the Scorpion 1200 SE.
JSB Exact Jumbo Heavy, 18.1 grains
Next, I tried the JSB Exact Jumbo Heavy domed pellet. This one is between the medium-weight JSB Jumbo and the heavier Beeman Kodiak, so it gives better velocity with some good power retention. If it shoots at least as well as the Kodiak, it would be worth choosing.
But it doesn’t just shoot better — it shoots WAY better than the Kodiak in the Scorpion 1200 SE. Ten pellets made a group that measures 0.792 inches between centers. The group is very round, as you can see, so we know this pellet is a keeper!
JSB Exact Jumbo 15.9 grains
The last pellet I tried was the 15.9-grain JSB Exact Jumbo. Sometimes this pellet is the best in a PCP rifle, so it had to be tried. This time, however, was not one of those times. Ten pellets made a 1.332-inch group that was not as tight as the Kodiaks or the 18.1-grain Exact Jumbo Heavys. And no wind caused the horizontal spread of these pellets.
The BSA Scorpion 1200 SE certainly has the power and accuracy needed to be a good hunting rifle. I like the way the stock balances in my hands when shooting, as it’s heavy at the muzzle. I don’t care for the fact that it needs 232 bar of fill pressure because that drains even a carbon fiber tank quicker than a 200 bar fill. It does, however, get a reasonable number of powerful shots per fill (25).
The 10-shot magazine is flawlessly reliable. There was never a misfeed in the entire test. And the magazine is below the top of the receiver, so it never interferes with the scope. The trigger is light enough, but I don’t care for the stage 2 creep that I found impossible to adjust out.
I would recommend this rifle to all who like its looks and features.

We’re back to the BSA Scorpion 1200 SE. My hand has finally healed, and I can now work the Hill hand pump, but I stopped part of the way through the first fill and made the necessary changes to the carbon fiber tank hose, to attach BSA’s proprietary fill probe. I gave up because I just got tired of pumping! Those who encouraged me to do this from the beginning have won me over, I guess.
This PCP rifle takes a fill to 232 bar, which is 3,365 psi. We’ve looked at fill pressures for pneumatics a lot over the past month, and today we’ll see what this BSA rifle manages to do with its fill. The advertised number of shots is 25 per fill.
Because of the power potential of this rifle, I switched my backstop to the tough one blog reader Jim Contos made for me. If you want to read about this fine homemade quiet pellet trap that’s strong enough to stop the most powerful smallbore air rifle, here’s the link.
Familiarization with the magazine
After 10 minutes of trying (and failing) to load the 10-round spring-loaded magazine, I was prepared to blast BSA for creating a magazine that’s impossible to load. What we had, instead, was a B.B. who refused to learn new ways. The magazine loads easily once you do it the right way! I took a photo of the correct hold, so you won’t have the problems I did. Hold it like this and realize that BSA has designed this mag so the last pellet loaded holds the spring-tensioned drum in place until you’re ready to load the next pellet, and everything will be fine.
The magazine accepted all 3 of the pellets used in this test without a problem. They’re among the heaviest and longest .22-caliber pellets on the market, so I think you’ll be satisfied no matter what you try to shoot.
Pellet 1 — JSB Exact Heavy and the shot count
The 18.1-grain JSB Exact Jumbo Heavy pellet averaged 883 f.p.s. in the rifle. The velocity ranged from 875 to 888 f.p.s. over 25 shots. And 25 shots proved to be the limit, exactly as advertised. After shot 25, the next 5 pellets went this fast.
Clearly, the rifle has just fallen off the power curve but in slow motion. So there are actually 30 safe shots on a fill, and that equates to 3 full magazines. I’m so glad BSA publishes accurate figures for these things, as many other airgun companies seem to have no clue what’s right!
At the average velocity, this pellet produced 31.34 foot-pounds of muzzle energy. And I bet this pellet is also accurate, though that has to wait until I get out to the range, because this rifle is too loud for shooting inside the house. I took a risk by chronographing it for today’s report, but that’s as far as I’m willing to go.
Pellet 2 — H&N Baracuda
The second pellet I tested was the 21.3-grain H&N Baracuda Match. These are longer pellets that sometimes have difficulty feeding through rotary magazines like the BSA’s, but there was no problem today! They averaged 815 f.p.s. and ranged from 811 to 819 f.p.s. At the average velocity, they produced 31.42 foot-pounds of energy at the muzzle.
The Baracuda is another pellet that should prove very accurate in this rifle. They should be the best pellet at 50 yards, but that remains to be seen.
Pellet 3 — Eun Jin
The third and final pellet I tested was the 28.4-grain Eun Jin dome. This is a very long pellet and may be the longest that will work safely in the BSA magazine. But they did fit perfectly and had no hangups once I learned how to load the magazine correctly.
Eun Jins averaged 718 f.p.s in the test rifle. They ranged from a low of 713 to a high of 726 f.p.s. At the average velocity, they produced 32.52 foot-pounds of energy at the muzzle. In other rifles, these pellets have never been the most accurate at 50 yards, but they have often been accurate enough to use as hunting pellets. However, as close as H&N Baracudas are in power, I would choose the most accurate of the 2 pellets after we test them at distance.
The velocity remained very tight throughout the entire fill with all 3 pellets that were tested. That means BSA has balanced their valve to work with exactly the amount of air they recommend using. And the fact that they got exactly the number of powerful shots they advertised was a welcome bit of news. Also, 25 shots is a good number for a rifle in this power class.
Adjusting the trigger
I mentioned in the first report that I would be adjusting the trigger in this report. To do that, the action is removed from the stock. The sear is a direct-contact type, so care must be exercised to not get the engagement surfaces too small, or the trigger will be in danger of jumping off from a bump.
The owner’s manual is a single sheet of paper printed on both sides, but the instructions for adjusting the trigger are good and thorough.
The screw on the left adjusts the trigger-pull weight of the second stage. The nut and screw in the center adjusts the sear contact area and then locks in place. That adjustment affects the length of the second-stage pull. The screw under the trigger blade on the right adjusts the first stage and should not be touched, according to the manual.
I adjusted the trigger as light as it would go and set the sear as close as it would go and still be safe. The trigger still has significant creep in stage two, but it’s light and breaks at 2 lbs., 4 oz. I can work with it set this way.
50 yards next
Because of the rifle’s power, I’m going to skip the 25-yard test and go straight to 50 yards. If I’m successful, we should see accuracy that will override shooting at 25 yards, anyway. If I discover that’s the wrong way to do the test, I’ll change at the range and shoot at 25 yards first.

It’s taken me awhile to get back to this pistol because I injured my hand, so I couldn’t fill the Hatsan AT P1 PCP air pistol from the hand pump for a couple of weeks, but last Friday I was at it again — probably for the last time. You may remember that I discovered that the AT P1 likes a fill pressure of 3,200 psi — which is sort of ironic in light of several recent reports I’ve done. This time, I used the Hill pump to fill the gun to that pressure to see if there are 10 good shots on a fill. That was the problem before — the circular clip holds 10 pellets, but the gun didn’t seem to want to shoot more than 7 of them on a single fill of air.
I decided that instead of wasting time with a lot of different pellets, I would concentrate on the one good pellet that I knew gave the best accuracy. That’s the Beeman Kodiak. First, I filled the gun to 3,200 psi, then loaded the clip and inserted it into the gun. Someone asked me how I held the gun to shoot it, given that it’s scoped with a Leapers UTG 3-9X40 AO rifle scope. The eyepiece has to be held within 2-3 inches of the eye in order to see the image. There’s a way to hold the gun that uses the scope as one of the handles, and that’s what I did. I photographed it for you, so you can see it as I describe the hold.
I hold the back of the scope at the eyepiece and let my hand separate the rear of the scope from my sighting eye by the required distance. My hand is pressed against my safety glasses to maintain the separation. The weight of the pistol rests directly on the bag, so all my other hand does is keep the pistol steady. With this hold, I can squeeze the trigger without moving the gun.
This hold is one I learned while shooting the LD Mark I pistol from Tim McMurray. That’s a Crosman Mark I Target pistol that Tim converts to add a longer bafrrel, a CO2 tank hanging down from the grip and a rifle scope mounted on top — just like this one. With the LD, I rested the external tank on my chest and held the scope like you see here. That gave me near-rifle accuracy.
The result is a steady hold — especially when you consider I’m shooting only 25 yards. I don’t recommend holding a recoiling firearm pistol this way, but you can get away with it on a PCP.
All targets were shot at 25 yards. The first target looked very good until the final shot. I could see that the pistol was grouping low and to the left, but all I was interested in was the size of the group. It could always be moved later with a simple scope adjustment. The group that formed looked very encouraging until the last shot, as I said. I could clearly see that one go high and into the center of the bull, ironically enough. But when I walked downrange to examine the target more closely, it wasn’t as good as it had seemed. A line of four shots appears to the right of the main group, and they’re strung vertically up to the center of the bull. The last one is the highest one. I never saw the other 3 shots in the string, so they could have been any of the preceding 9 shots. All I could see through the scope was the large group that formed at 7 o’clock on the edge of the bull.
I guess this first target took the wind from my sails. It was no better than any of the previous targets shot with this pistol. My idea that a higher fill pressure would keep 10 shots in a tighter group was bogus. But I still had time on the range, so I thought something else was in order. I adjusted the scope higher and to the right just a little, to correct for where the Beeman Kodiaks had grouped. Then, I loaded the gun with 10 JSB Exact Monster pellets. The Monster pellet weighs 25.4 grains, making it even heavier than the .22-caliber Beeman Kodiak. And it’s a JSB. I wondered if this might be the pellet that turns things around for the AT-P1 pistol.
Alas, it wasn’t. It turned things around, all right, but not for the better. The pellets were all over the place! In the end, 10 of them printed a group measuring 1.933 inches at 25 yards. It’s more of a full-choke shotgun pattern than a group shot from a rifled barrel!
Now, I was really downhearted. I switched back to the Kodiaks and give them one final try. The gun was, again, filled to 3,200 psi, and 10 more pellets went downrange. This time, the results were not as good as the first time. Ten pellets made a group that measured 1.211 inches between centers. It was higher on the target and also centered better, which proves my earlier statement that the group can always be moved by adjusting the scope, but things were not getting better.
Outcome and final evaluation
I put a lot of time and energy into testing the Hatsan AT-P1 pistol. The reward was not worth the effort, in my opinion. While I agree that Hatsan does know how to make a fine precharged air rifle, the AT-P1 pistol is not as refined as the rifles they make. It’s too large and too coarse for what it delivers. I wanted it to succeed because there aren’t that many nice PCP pistols to choose from, but the test results do not live up to the hope.
I think that if you’re interested in an airgun like thi,s you should look at the AT-P2 pistol, which comes with a shoulder stock. That way, you won’t have to learn how to hold the gun like I did here. As long as you know how few shots you’re going to get on a fill of air (7) — and you manage that, you’ll be fine.
