This report covers:
• Accuracy at 20 yards
• Accuracy at 40 yards
• Trigger and safety
• How loud is it?
• Final thoughts
In the first report, we used a chronograph to measure the velocity of the .25-caliber BSA Scorpion SE. Just looking at the chrony numbers, I would guess that .22 caliber is really optimal for the Scorpion SE. I’d bet a rifle in that caliber could put out the same energy as the .25 and maintain the same or better shot count. But don’t discount the .25-caliber Scorpion SE. While clearly underpowered, today’s accuracy testing will show just why the this rifle should be on your short list.
Accuracy testing was done at 20 and 40 yards. Normally, I would do 25 and 50 yards, but my current range has a max of 40 yards. The Bushnell Elite 8-32X40 scope was set on 16X, and the shooting began. I should note, I was using only a front bag rest and shooting off a very wobbly plastic table, but even those hindrances could not keep the Scorpion SE from impressing me! A .25-caliber hole is a bit bigger than I’m used to seeing. I shot 3 groups to warm up and then refilled for the 20-yard test.
Accuracy at 20 yards
The first pellet shot at 20 yards was the JSB King. They stacked 5 into a tight 0.43-inch group, starting things out nicely.
Next was the Benjamin Destroyer pellet at 27.8 grains. This is shaped similarly to their Destroyer in .177 and .22 calibers. Four shots went into a 1.30-inch group, with the fifth shot flying high about 2 inches. The overall size came to 2.60 inches for 5 shots, which is beyond poor. The Benjamins were not included in the 40-yard test for that reason.
The Predator Polymags did surprise me a bit. Not only did they just barely squeeze into the magazine, but they actually grouped pretty well. A 0.54-inch group of 5 at 20 yards made a nice-sized hole that would certainly be adequate for small game. The Polymags have proven, time and time again, that they’re the premier hunting-specific pellet and can smack small game with devastating results.
The lighter-weight H&N Field Target Trophy grouped decently, with 5 in 0.79 inches. I pulled the fourth shot a bit, as my wobbly table wasn’t quite stable. I did shoot them at 40 yards, as well, but the results were not worthy of showing here.
The pellet that surprised me the most was the H&N Baracuda Hunter Extreme. With a cross cut on the head of the pellet, it’s certainly eye-catching, with major accuracy to back it up! A 0.35-inch, 5-shot group (basically one single hole) was more than enough to get my attention. Twenty yards is not a long distance for PCP guns; but when you lace 5 shots in a row through a single hole, it immediately gets your attention!
Next up were the Beeman Kodiaks. Being made by H&N, I was pretty confident they’d group similarly to the Baracuda Hunter Extremes, and they did. A 0.32-inch group of 5 bettered the mark set by the Hunter Extremes at 20 yards. The two pellets are very similar in terms of shape; and aside from the cut out in the head of the Hunter Extreme, they showed little difference in accuracy at 20 yards.
Accuracy at 40 yards
I chose to go with the Kodiaks, Hunter Extremes, Predator Polymags and JSB Kings for 40-yard testing. The results were all very good, which shows the versatility of the BSA barrel. This is something I’ve come to appreciate about the BSA guns I’ve owned. They all seem to be very even-tempered in terms of pellet selection. All too often, I test guns that will shoot only one pellet, and everything else groups horribly. That’s all well and good, but only if the pellet the barrel likes is accessible, consistent from die to die and not too far on either side of the weight spectrum so your trajectory is reasonable. For testing at 40 yards, I shot two groups just to try to remove the potential for human error because we all know the gun is rarely the problem. It’s the jerk behind the trigger!
First up were the Beeman Kodiaks, and they did not disappoint — giving a 0.50-inch group. Bear in mind the pellet is half the size of the group, so you are looking at two holes at the end of the day.
The Predator Polymags at 26 grains grouped very well at 40 yards, making a 5-shot group that measured 0.65 inches. I would be very confident with a magazine of these in the Scorpion SE if I was going out after squirrels or pest birds. Raccoons and opossums would also be well within the Scorpion SE’s game menu. Accuracy like this will pretty much assure you of a clean head shot or vital organ shot if you do your part. The extra bit of expansion the Predators offer would also come in handy.
The overall best group of the day (and not just at 40 yards) was made with JSB Kings. After looking like the H&N/Beeman pellets would run away with the accuracy testing, the Kings came back in a big way. I managed to put 5 shots into a single hole measuring 0.27 inches. Basically, that’s the size of the pellet. The next group opened up ever so slightly, but it was clear that the Kings are the way to go.
The Baracuda Hunter Extreme was the last pellet tested at 40 yards, and they grouped well also at 0.42 inches for 5. That was the best I could manage; and if the expansion of the Hunter Extremes is better than the average domed pellet, then I would say they’re the most accurate hollowpoint I’ve ever shot in any gun past 10 yards. Generally, hollowpoints suffer a bit in the accuracy department; but I think that because the Hunter Extremes are not a complete hollowpoint, they fly just a bit better. Either way, these pellets work well, so H&N has a definite winner with them.
Trigger and safety
The trigger on the BSA Scorpion SE was unadjusted since it came out of the box crisp and relatively light for a hunting trigger. It measures an average of 2 lbs., 2 oz. over five pulls. I know the trigger can be adjusted much lighter than this; but for the hunting crowd, that won’t be necessary.
The manual hunter-style safety is located on the left side of the action. I’ve seen the triggers adjusted so light that an engaged safety won’t stop the gun from firing when the trigger’s pulled. So, be careful when adjusting this trigger — or any trigger for that matter. Test it before you load the gun and make sure the safety still stops the gun from firing after adjustments are made.
How loud is it?
On the subject of noise, the Scorpion SE is pretty loud. It’s not backyard friendly, and I would rate it a 7 out of 10 (10 being the loudest). If this were a 45-50 foot-pound gun, then the noise would be up in the 9-10 range; but at 30 foot-pounds, it’s fairly tame for an unshrouded gun. That said, the air stripper on the muzzle also doubles as a thread protector covering the 1/2-inch UNF threading that could accept a more useful air stripper or muzzlebrake if you choose to add one. [Editor's note: Silencers are subject to federal legislation. If an airgun silencer can be attached to a firearm and quiet the report, it must be licensed.]
The Scorpion SE represents a step forward for BSA airguns. The new features like the redesigned magazine and gauge show that they’re listening to what their customers want and need. All the while, they’re not changing the things they know are proven to work. Their barrels are still some of the best out there, and their overall quality and precision shines through.
There are a lot of options in the mid-priced PCP realm, and the BSA may be overlooked because of its relatively low power level; but if you’re looking for a precision shooter with adequate power for small game, then I would highly recommend taking a look at the BSA Scorpion SE. My experience with BSA products has been stellar over the course of many years, and I’m confident you’ll come to the same conclusion after just a few shots behind the trigger of their PCP works of art!

I’m still in Ft. Smith, Arkansas, filming segments for this year’s American Airgunner TV show, so today’s report will be short. After I reported the 50-yard accuracy test for the EscapeUL, blog reader Gunfun1 asked me if I had remembered to coat the pellets with Slip 2000 oil that Ton Jones likes. I had to admit that I’d forgotten, so I promised him I would. Last Friday, I went to the range and shot the EscapeUL with just the 2 best pellets — the 43.2-grain Eun Jin pointed pellet that develops the maximum power in the rifle, and the Predator Polymag pellet that was the most accurate on lower power.
The first pellet I shot was the Predator Polymag. I did that because the rifle was still set on the same power setting I used in the last test. If you recall, I shot 2 groups of Polymags that time. One was 5 pellets in 0.622 inches at 50 yards. I thought that was phenomenal! The second group of 5 opened up to 1.298 inches, but I shot it in a continuous wind. I just waited for quieter moments, but the wind was always blowing for that group.
Oiling the pellets
I put several drops of the Slip 2000 lube on the foam that JSB packs in the tops of their tins. Predator Polymags are made by JSB, so they always have this foam. Then, I put some pellets on the foam and rolled them around until they were moist to the touch.
The first target I shot looked like it was going to beat my earlier best group; but after 3 shots, the rifle threw the next shot to another location, opening the group much larger. Okay, I thought, maybe I didn’t get the fill pressure just right. I continued shooting until there were 6 shots on this target. The entire group measures 1.545 inches between centers. That isn’t bad; but in light of what I did before with unoiled pellets, I wasn’t happy with it.
This group suggested to me that the EscapeUL doesn’t like oiled pellets. It seemed like once the bore was oily, accuracy went south. Of course, I couldn’t let it ride without testing it once more. This time, the pellets were oiled in the same way, but the bore was already oily. I mention that because the next group of 5 wasn’t nearly as good as the first. Five Predator Polymags went into 2.634 inches! And that was what I expected would happen. When I saw the pellets in the previous group opening up, it was something I have seen before. Oiled pellets often do this, in my experience.
The wind was starting to pick up, so I switched from Polymags to Eun Jins. This time, I ran the power up as high as it would go and filled the reservoir to 3,000 psi. The last time, I shot 5 dry Eun Jin pellets into a group that measured 1.866 inches at 50 yards. That set the bar for the oiled pellets.
And the challenge was met! I got an almost-identical 1.862-inch, 5-shot group with the oiled Eun Jins. The measurement error is larger than the difference between these 2 groups!
Sometimes, you win…and other times not
I know this isn’t a huge test with lots of controls and numerous targets. But I didn’t think oiling the pellets was actually going to help. From what I see here, it didn’t. It’s just one extra step for little or no return. I certainly would not oil the Predators, again!
The one advantage I see with oiling is that it makes the pellets load easier. At least it does for the Predators. The Eun Jins load very hard no matter what you do. I had to use the flat side of the screwdriver blade on my pocket knife to get them into the breech — even after oiling!
I doubt I’ll oil pellets for this rifle again.

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.

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.

Benjamin Marauder .177 caliber 50-yard test: Special part
Well, it’s certainly been a long time between reports on this rifle, hasn’t it? Today, we’ll begin looking at the accuracy of the .22-caliber Benjamin Marauder with the synthetic stock. Some of you have already asked me if I plan to also test the new wood-stocked Marauder that has the same new action as this one. I have no plans to test it because I feel this test encompasses everything on the rifle, except for the stock material.
I was particularly keen on testing this rifle because we had a couple new readers who had purchased this gun and were having accuracy problems with it. I wanted to pay closer attention to accuracy than normal. After all, this is a new action, even if the changes have been relatively minor. Also, this is the first .22-caliber Marauder I’ve tested. Since Crosman makes both the .177- and .22-caliber barrels and buys the .25-caliber barrels from Green Mountain, I feel it’s worthwhile to examine this rifle more closely.
I filled the rifle to 3,000 psi because we learned in Part 3 that it’s on the power curve with a 3,000 psi fill. Then, I fired a single shot from 12 feet to see if I was on paper. Following that, I backed up to 25 yards and refined my sight picture. Only the 14.3-grain Crosman Premiers went everywhere! I got them on target, but sometimes a pellet landed an inch away from the aim point.
What was happening?
This is what a couple readers had described, so I did what I advised them to do. I removed all the baffles (see Part 2 of the Synthetic Stock review for this) to see if the pellets were touching any of them. Since they’re just plastic, it would be obvious if a pellet nicked one; but there was no sign of this on close inspection. So, I assembled the baffles and closed the shroud again.
And the next 10 shots with Premiers were remarkable! They went into a group that measures 0.246 inches between centers. Right away I guessed what might be happening is that the rifle was smoothing out as the air pressure dropped. So, even though the power curve seems to support a 3,000 psi fill, the targets do not show the same thing.
You can’t tell everything from just a single group — even a tight one like this. More testing was needed, but now I would be careful about the pressure level at which the groups were shot.
I tried many more pellets, but I’m not going to show all the groups. In all, I fired a total of ten 10-shot groups, making this test more exhaustive than my usual 25-yard accuracy test. I wanted to pin down this pressure-versus-accuracy correlation to see if it was real or imagined.
JSB Exact Jumbo
The 15.89-grain JSB Exact Jumbo pellet gave a very clear example of how the pressure affects the groups. The first group was fired from a fresh 3,000 psi fill and 10 pellets went into 1.131 inches. You can tell at a glance that the pellets are scattered around.
The second group of the same JSB pellets was fired after the first group. By this point, the rifle’s internal pressure has dropped to the mid-2,000 psi point (2500 to 2600 psi). This group still isn’t a good one, but you can see that it’s tightening up. It measures 0.872 inches between centers.
On the third group of 10 shots (still on the same fill), the group really tightened up. These 10 went into 0.592 inches. That’s a good group, but maybe I don’t want to use this pellet in this rifle because it seems too fussy.
No Predators, no Newboys!
I tried both Predator Polymag and Skenco Newboy Seniors, but both were too long to fit in the Marauder’s rotary magazine. If you want to use these pellets, you’ll need to use a single-shot tray; and since Crosman no longer makes them in .22, good luck finding one. Of course, you can load pellets without the tray, but it’s more difficult to align them with the breech.
I wondered how Premiers might do on the third batch of 10 shots after the fill. Ten pellets went into 0.496 inches. Not as tight as the second 10 after the fill, but still very good!
JSB Exact Jumbo Heavy
The 18.1-grain JSB Exact Jumbo Heavy pellets behaved much the same as the regular Jumbos, except the groups were tighter. The first 10 went into 0.653 inches; the second 10 went into 0.657 inches, and the third batch went into 0.591. All 3 groups are pretty close to one another; but in light of the Premiers and the Kodiaks we have yet to see, I don’t think they’re the best in this particular rifle.
I was burned out when I got to the Beeman Kodiak pellets — 100+ shots is too much for a single session when every shot requires concentration. I didn’t mention shooting RWS Superdomes yet. I did shoot 1 group with them, and it was a bust at 0.83 inches. When I got to the Kodiaks, I wasn’t concentrating as well as I would have liked. And I shot this single group on a fresh 3,000 psi fill. I felt I could get away with that because of the weight of the 21-grain Kodiak pellet.
And I was right. Even though I was fading, 10 pellets still went into a tight round hole that measurtes 0.378 inches between centers! It’s the second-best group of the test and earns the Kodiak a spot in the 50-yard test, for sure!
What I’ve learned
The first thing I learned from today’s test is that this particular rifle doesn’t seem to shoot as well on a fresh fill as it does on the second and third magazine of pellets. So, if you stop filling at 2,600 psi, you’ll get 20 good shots from the rifle and not waste any air. I also learned that Crosman Premiers are the miracle pellet in this rifle, just like they’ve always been.
That last group of Beeman Kodiaks has me thinking that Premiers and Kodiaks will battle it out at 50 yards for the overall accuracy championship. I know Premiers are aerodynamically excellent, but the Kodiaks look like a real challenger in this air rifle.
I need to comment on the noise, or lack of noise. This .22 caliber Marauder is extremely quiet. It’s more like a .177 than it is like a .25 in that respect.
I expected to have problems with accuracy when I encountered those wild shots during sight-in. But by hanging in there and shooting both the second 10 and the third 10, I learned that this rifle likes to push its pellet slower than most. I would have to live with the gun for a long time to learn all of its secrets, but the test rifle is a very accurate PCP that’s worthy of the Benjamin Marauder reputation.
I like the synthetic-stocked rifle, but in my opinion it is no better than the older model in the wood stock. I never minded the thickness of the old wood stock, so I’m just going on the performance of the gun at this point.
