Just a word
Befoere I get started with today’s report, I want to say something about what happened this weekend. Friday’s airsoft report got a lot of comments. Among them are several questions about the technology of the guns. And some admissions that people didn’t think much of airsoft before they tried it, then they found their opinions changed drastically. That also happened to me, so I can relate to it.
But all you who don’t care for the subject don’t need to worry. This isn’t going to become an airsoft blog. I will continue to report on it at a low level, but I know this is an airgun blog, and that’s not going to change. I want to assure the readers for whom the subject of airsoft is not welcome that we are still going to talk about pellet guns and BBs guns for the most part. I will write a few reports on airsoft now and then, and I trust they won’t upset you too much.
Okay, that’s done. On to the topic of the day!
Today is our second look at the .22-caliber Octane combo from Umarex, and it’s velocity day. Before I get to that, there are a couple adjustments I wanted to make to the rifle. Let’s look at those now.
The first adjustment is the trigger. In the first report, I said the trigger is crisp but heavy. The adjustment screw adjusts only the length of the first-stage pull; so I adjusted it to be longer, and stage 2 decreased. Don’t go too far or the rifle will not cock at all because this adjustment does affect the area of sear contact.
I did go too far and had to call Umarex USA, where I learned that the Octane is supposed to come with a warning tag telling you not to turn in the adjustment screw more than one full turn. I went way past that, so all I had to do was turn the screw back out until the head stood even with the trigger blade — and the trigger was back to working again. For even greater contact, turn the screw so it stands proud of the trigger blade.
The second thing I wanted to adjust is the tension on the action forks because the barrel pivot was too loose. To do that, I normally take the barreled action out of the stock. But with this rifle, you need to be aware that the pins in the trigger are not held in and will fall out of the trigger if the action is tipped sideways. I didn’t know this, of course; and when the first pin fell out, it set me up for 45 minutes of work to get the trigger back together again. It seems that the trigger pins are held in place by the stock. Other airguns I’ve worked on have the same arrangement, and one solution is to put tape on one side of the trigger to hold the pins in place…and keep the trigger oriented straight up and down.
Each of the 6 free (not held by circlips or springs) trigger pins seen here is very loose in its hole and will fall out of the trigger if the gun is jostled or tipped to the side. They’re held in place by the stock. What appears to be a pin at the far right is actually a rivet.
Better still — what you can do (VERY CAREFULLY!) is remove both forearm screws and just LOOSEN the rear screw behind the triggerguard. Then the front of the action can be tipped up clear of the stock far enough to tighten the barrel pivot bolt and nut. I would advise against taking the action completely out of the stock. If you do, know how loose the trigger pins are and treat the rifle accordingly. When the pins fall out, the internal trigger parts start moving around. They’re fairly easy to align with their pin holes, except for the safety that takes a little fiddling since it’s a 2-piece assembly with an internal pivot. My advice is to leave the gun in the stock.
One final tip. When you tighten the stock screws, don’t tighten the rear stock screw (the one behind the triggerguard) too much or the trigger won’t function. It was not tight when I first took the action out of the stock; and I found that if I tightened it too much, the trigger would not work. Umarex told me the screw shouldn’t affect the trigger at all, but I’m just reporting on the behavior of my test rifle.
Now, let’s look at the velocity of the Octane. I’ve selected 3 popular lead pellets and one lead-free pellet.
JSB Exact Jumbo
The first pellet I tested was the 15.9-grain JSB Exact Jumbo. This is a popular and very accurate pellet in many airguns, and I think it may be accurate in the Octane. This pellet averaged 762 f.p.s. in the Octane. The low was 748 f.p.s., and the high was 787 f.p.s.; so the spread was 39 f.p.s. At the average velocity, this pellet produced 20.51 foot-pounds of muzzle energy.
This pellet loaded easily, perhaps too easily. I think it might be a little undersized for the Octane’s breech. That could affect the accuracy. We’ll see.
The RWS Hobby pellet weighs 11.9 grains in .22 caliber and is very tight in the Octane’s breech. It averaged 889 f.p.s. in the rifle with a low of 867 and a high of 902 f.p.s. So the spread was 35 f.p.s. At the average velocity, this pellet produces 20.89 foot-pounds of energy at the muzzle.
I don’t know how Hobbys will do in the Octane, but I suspect they’ll do well because of the tight fit in the bore. Of course, the Hobby is a wadcutter, so accuracy will fall off after about 25 yards.
The .22-caliber Beeman Kodiak dome weighs 21.14 grains, which makes it a very heavy pellet. In the Octane, Kodiaks averaged 682 f.p.s. with a range from 665 to 691 f.p.s. That’s a total spread of 26 f.p.s. At the maximum velocity, the Kodiak produces 21.84 foot-pounds at the muzzle.
My guess is that the Kodiak pellet might also be a good one for the Octane. If so, that’s great because it also produces the most energy of all the lead pellets tested.
Okay, the name of the game with pellet rifles these days is speed, and the RWS HyperMAX lead-free pellet at 9.9 grains is the way to get it. In the Octane, they averaged 1029 f.p.s. with a spread from 1022 to 1075 f.p.s. That’s a spread of 53 f.p.s., so the rifle is probably still burning a lot of fuel. At the average velocity, the HyperMAX pellet produced 23.28 foot-pounds of energy at the muzzle.
The HyperMAX pellet fit the breech very loosely. That’s probably where the extra velocity spread came from, as more dieseling was generated by less pellet resistance. I doubt this pellet will do very well in the Octane because of the loose fit.
The rifle recoils noticeably in both directions, but there’s no vibration, whatsoever. Nearly all rifles with gas springs have a sharp buzz that hits you in the cheek, but the Octane doesn’t. In fact, aside from the recoil, it’s a very smooth-shooting spring rifle.
Remember that I had to adjust the trigger for a very definite stage-2 let-off. That affected the trigger-pull a lot. I was able to adjust it back to a release of 7 lbs., 14 oz. with very little creep. It’s heavy, as I noted before, but I think it’s crisp enough to do good work. We shall soon see!
The Octane IS NOT LOUD!
When I first tested the rifle it was very loud. And the sound persisted for longer than I felt the dieseling of a new airgun would last. But during this test the rifle suddenly became MUCH quieter. Obviously, it had been dieseling and I didn’t know it.
I originally told Edith it was a 3.7 on the sound scale when I tested it, and she adjusted the loudness level on Pyramyd Air’s product page to 4. But now she can hear that the Octane is clearly a 3. I apologize to everyone who was mislead by my earlier report. The Octane is a normal-sounding breakbarrel air rifle.
Observations thus far.
I said in Part 1 that the Octane holds very well in the hands. The weight is biased forward toward the muzzle, and the stock is slender when the off hand rests. Add the smooth shooting to this, and I think the Octane might surprise us in the accuracy test.
I plan on shooting the rifle at 10 meters with its open sights first. That should give us an idea of which pellets it likes. Then, I’ll mount the scope and shoot those best pellets at 10 meters, again. That does 2 things. First, it confirms the pellets are as good as we think; and second, it allows me time to adjust the scope for the second accuracy test at 25 yards.

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.

It’s been some time since I did Part 3 of the Evanix Rainstorm 3D bullpup rifle. Just to remind you of where we left off, I found the gun difficult to shoot with the UTG 3-9X32 Bug Buster rifle scope because of the medium-height scope rings. I removed that scope and mounted the UTG 3-9X40 True Hunter rifle scope that comes bundled with high 2-piece Weaver rings. They were better, but even they seemed a bit too low because of the bullpup configuation. This is the same scope I used in the test of the Hatsan AT P1 PCP pistol.
Today’s test was done at 50 yards on an outdoor rifle range. The weather was perfect, without a hint of breeze. I didn’t sight-in the scope before going to the range, so I sighted-in at 50 yards. Luckily, the scope wasn’t that far off, and I was on target in 3 shots.
The 25-yard test that was done in Part 3 showed that only 2 pellets were worth trying at 50 yards. I shot just them and nothing else.
I also want to remind you that the rifle likes to be filled to 2,900 psi according to my tank’s gauge. It has more than 10 shots on a fill, but it does go through air pretty quick. So, just for continuity, I refilled after every group.
JSB Exact 15.9-grain domes
I sighted-in with the best pellet from the earlier test, which was the 15.9-grain JSB Exact Jumbo Heavy. Since the third shot landed where I wanted, I continued to shoot and made an 8-shot group for starters. That group measured 0.961 inches between centers. I noted that the bullpup-style stock made the rifle difficult to hold steady on target, so this group was as steady as I was able to hold. I was fighting the trigger, which breaks at 6 lbs., 10 oz. It’s hard to hold on target with a trigger this heavy. Also this rifle is tall and narrow, so it wobbles from side to side when you hold it. I didn’t see a way around that at first, but then I figured it out.
Next, I shot a 10-shot group with the same JSB Exact Jumbo Heavy pellets. The rifle’s circular magazine holds 11 pellets, but I loaded it with only 10 to keep things consistent with most of my other 50-yard tests.
The scope had been adjusted higher for this group, so the shots landed higher on the bull. Ten pellets made a 1.501-inch group. I must comment that during this group I saw the crosshairs move around on the bull a lot more than I would like. That heavy trigger caused it. In the group that resulted, I see 2 separate points of impact that are one above the other. That isn’t what I would expect a sideways wobble to produce, but something was wrong with my hold. I had to solve that first.
Toward the end of the first full group, I found a way to stabilize the rifle pretty well. I was shooting off a sandbag rest that helped with stability, and I found that if I gripped the frame tight (where the forearm would be on a conventional rifle) the wobble stopped. That made me more confident that the group I would be getting was what the rifle could actually do.
Following that group, I shot a second group of 10 JSB Exact Jumbo Heavies that measured 1.406 inches between centers. This one is fairly well centered on the bull and doesn’t have the 2 separate points of impact like the first group. I think the improved hold was responsible, although I can’t see why a sideways wobble would do what I’d seen before. Maybe the wobble was greater than I thought?
The second full group was a little smaller than the first — at 1.406 inches between centers. I felt the rifle was held well for this group. This is as good as this pellet can do (in general) in this rifle with me on the trigger.
Next, it was time to try 10 Beeman Kodiak, which was the second-best pellet at 25 yards. It didn’t do as well. The first few shots scattered all over the place, landing far to the left of the aim point and also a bit lower. When all 10 shots were finished, I had a 2.32-inch group that looks more like a shotgun pattern than a group from a rifle. However, I must note that 9 of those shots did land in a 1.331-inch group. But the one lower shot that opened the group wasn’t the last one. It was the third shot. Based on that, I would scratch Kodiaks for this rifle and stick with the JSB Exact Jumbo Heavies.
I’ve come to the end of my test of this air rifle. It’s been an interesting journey, and I’ve learned some things from it. First, when you scope a bullpup, get the highest scope rings you can. Ring risers might be a good idea. Second, the idea that bullpup actions have poor triggers is apparently true. And finally, when the cross-section of your rifle is as flat as a flounder, it will be harder to hold steady.
The Evanix Rainstorm 3D bullpup rifle is definitely a different beast! It holds different and shoots different than a conventional PCP. If you’re looking for the bullpup styling, then either this or the Evanix Max bullpup is the airgun you want. It will produce acceptable accuracy out to 50 yards when you do your part. Just remember that the trigger is stiff and creepy, and the rifle needs a firm hold.

Wow! More than one month has passed since the last part of this report. I’ve been to the Roanoke airgun show and also out to the rifle range at least 3 times trying to get the data for today’s report, but what a quest it has been! It all boiled down to false confidence in my ability to get the job done. I’m used to certain rifles cooperating with me every step of the way, and this time I got called by the fates who expose pride for what it is.
I’m not going to bore you with all the details, but I will point out the most recent example of my stupidity because it’s a lesson for us all. When I went to the range last week, I thought I was ready to complete my 50-yard test of the .25-caliber Benjamin Marauder. I’d swapped the scope mounts from a previous test because they were too high. The new mounts were lower, and I didn’t have to hold my head as high on the comb. I knew this would help with the accuracy. But then I went to the Roanoke airgun show, and forgot that I’d made this change.
What’s most important about the change, though, are that the new mounts were vintage B-Square adjustable mounts. And the rear ring was jacked up higher than the front. I always liked that setup because it gets the drooper problem taken care of on the first shot — even if there isn’t one! But not if you forget that you did it!
And that’s why this report didn’t happen last week. I had the Marauder at the range with the TX200 Mark III, on which I reported last weekWhen I shot the Marauder, there wasn’t a pellet hole on the paper. And I’m not just talking about the target paper, either. I mean the 2-foot x 4-foot backer paper that I use whenever I have a rifle that’s not known to be sighted-in.
Naturally, I was disappointed. This was a Marauder after all, and I expected it to go right to the point of aim. After shooting just two 8-round magazines, I took the rifle off the line and put it away. I needed to look into the situation deeper and figure out what was wrong.
What was wrong, was that I had forgotten about the new scope mounts. When I looked at the scope back in my office, I immediately saw that the rear was higher than the front. Then I vaguely remembered something about changing the mounts before going to the Roanoke airgun show, so I reread the last report and discovered what had happened. The gun had not been sighted-in with the new mounts. It was obvious that the scope was set up for a rifle with severe barrel droop, and this rifle doesn’t have that.
I even went back to the rifle range last Friday and looked at the backer board where my target and backer paper had been stapled. Sure enough, above where the top of the paper had been there was a hole in the backer board. It had the appearance of a nice rifle group. And some of the holes in the group appeared to be .25 caliber.
Suspecting what happened, I started shooting at an aim point much lower than my anticipated target. Sure enough, my pellet was hitting the paper about 16 inches high and 6 inches to the left. That’s a problem I can deal with! All I had to do was adjust the scope down and to the right, and I was on target. It took me less than 10 minutes to get my groups landing where I wanted at 50 yards. Now, it was time to test the rifle.
The first group was shot with H&N Baracuda pellets. In the past, these were the most accurate .25-caliber pellets on the market, but they have since been replaced by several others, including one huge surprise that emerged in this test! The group measured 1.021 inches between centers. It’s a good group for any rifle at 50 yards, but I did think the Marauder might be capable of better.
I should mention that I was firing two magazines of eight shots each in this test. So the groups that you see have 8 pellets and not 10 in them. I recharged the rifle with air after every 16 shots because the reservoir pressure had dropped to around 2,100 psi by that point. That was as low as I felt it could go and still be accurate.
JSB Exact King
The next pellet I tried was the JSB Exact King, a .25-caliber pellet that’s shown a lot of promise in recent testing. The first group I shot measured 1.447 inches between centers. That’s not very good for a PCP rifle at 50 yards. Interestingly, however, 7 of those 8 shots went onto 0.719 inches, and that is good. I hoped that the one flyer was an anomaly, and that a retest of the same pellet would do better.
The second group of JSP Exact Kings when into 1.094 inches. That’s a lot better, but it still wasn’t what I’d hoped for, so I left the Kings to try other pellets.
Another stunning pellet in .25 caliber is the Benjamin dome. It has no model name, but you could think of it as a Premier pellet because it looks similar to the other pellets in the Premier line. The first group of 8 pellets measured 1.226 inches between centers, which was again larger than I was looking for.
The second group of Benjamin domes measures 1.06 inches. While that’s better, I still thought the rifle could do more.
The last pellet I tried was the .25 caliber Predator Polymag. It showed well in the 25-yard test and earned its place in this test. There really aren’t a lot of options when it comes to accurate .25-caliber pellets, and I think we’ve included all of them in this test. Yes, there are other brands out there, but do they perform? In my experience, they don’t.
The Predator is a hollowpoint pellet that has a red plastic tip in the center of the nose. Normally, hollowpoints fall off in accuracy at around 25 yards, but this pellet doesn’t. That tip seems to do its job.
The first group of Predators measures 1.121 inches between centers. Once again, that’s okay for 50 yards, but it’s nothing to scream about. But the second group measures 0.808 inches between centers. That’s what I was looking for! While the Marauder can’t be expected to shoot that well every time, this group proves that it has the potential. And it does it with a pellet that is acknowledged to be a great hunting pellet!
No .25-caliber airgun has ever been as accurate as the best .22 or .177 guns. What we see from this test is a range of results that represents what the .25-caliber Benjamin Marauder can do at 50 yards. I think these groups show what this gun can do very well. Sure, if you shoot more there will be some smaller groups. But there will also be many more groups that are larger than those shown here. I think we can safely say the Marauder in .25 caliber is capable of putting 8 shots into one inch at 50 yards when you do your part.
The .25-caliber rifle uses a lot of air! I was getting just 16 good shots in this test on a 3,000 psi fill. Compare that to the 32 good shots I got in the test of the .177-caliber rifle filled to the same pressure.
From a handling standpoint, there isn’t a nickel’s worth of difference between the .177- and .25-caliber rifles. The trigger can be adjusted to operate virtually the same, and the stocks feel the same. The one small difference is the .25-caliber gun does move back slightly with each shot. I didn’t feel that with the .177, but I definitely felt it in this test.
If you want a .25-caliber hunting air rifle, I think the Marauder is a good candidate for your short list. It’s powerful, accurate, quiet and reliable. How much more can you ask?

The Chinese Fast Deer sidelever air rifle is attractive. Does its performance live up to its looks?
It’s been a long time since we looked at the Fast Deer sidelever. The last report was in December of last year! At that time, I was unsatisfied with the results of the 25-yard targets because of how well the rifle seemed to do at 10 meters. I said we might come back to it, but the gun got put on the back burner to simmer while I did other things.
It was those other things that bring you today’s report, and surely the ones that must follow. I’ve spent a lot of time this year exploring the fundamentals of airgun accuracy. Of course, I’ve barely scratched the surface, but some of the things that have popped up have been surprisingly helpful in ways I couldn’t imagine when they happened. One of them was the test of the Diana model 25 smoothbore that we finished way back in March of this year. In Part 4 of that test, I saw that while the smoothbore was very accurate at 10 meters, it was pretty bad at 25 yards. From those results, I deduced that spin is important to stabilizing a pellet over longer distances, while the high drag of the diabolo pellet is sufficient for accuracy at close range.
It wasn’t until I wrote a column about the Fast Deer for Shotgun News this month that I noticed the Fast Deer’s 25-yard targets resembled those of the Diana 25 smoothbore more than a little. The Fast Deer was also accurate at 10 meters but not at 25 yards. So, here was a rifled bore that performed like a smoothbore. Could we learn something from this? Is the Fast Deer capable of better accuracy than we saw in Part 4?
I was so impressed by these results that I wrote a special report titled Advanced airgun diagnostics: Part 1, in which I showed you the comparison between the 2 airguns. Yesterday I tested the Fast Deer again at 25 yards, but this time I did so believing that it was the fault of the pellet that made the groups so large. Turns out I was only partly correct, and therein lies the meat of today’s report.
I had one pellet that fit the Fast Deer’s bore well…both the skirt and the head. It’s a Tech Force domed pellet that Pyramyd Air used to sell but no longer does. That makes it a Chinese pellet, and I’ve seen only one other Chinese pellet that was worth a darn. That one was a hand-sorted wadcutter that I used to compete with in 10-meter pistol.
These Tech Force domed pellets are larger than most. They fit the bore of the Fast Deer rifle well.
The subject pellet fits the bore well, but not tight. Many other pellets just fall out of the breech, indicating a too-large bore, which is characteristic of Chinese air rifle barrels. I knew from the last test that the rifle was at least on paper at 25 yards, so I set up at 25 yards indoors and commenced firing. The first 10 pellets all landed to the right of the aim point, but they were all on paper, so I finished the first 10-shot group with the sights set where they were. This group measures 1.428 inches between centers. That’s not great, BUT — it’s actually smaller than the best group I had fired in the entire last report! In that session, the best group was shot with Air Arms Falcon pellets, so I knew I had to try them again for comparison; for now, I stayed with these Chinese domes.
Ten pellets made this first 1.428-inch group. It may not look good, but this is the best 25-yard group this rifle has made so far.
After the first group was completed I adjusted the rear sight to the left. You may remember that I had flipped the sight backwards in response to a suggestion blog reader Vince gave me. That gives a sharper rear notch when aiming, and any little thing like that will help. So, all adjustment had to be done backwards; but since this sight has a very visible index mark to watch, the adjustment was no problem.
As I adjusted the sight, I also discovered that the entire unit is loose. It’s mounted on the gun securely enough, but the very construction of the sight itself is a sheetmetal tangle of parts that will always be loose and subject to movement.
The rear sight is clearly marked and easy to adjust, but it’s always going to be loose because of how it’s made.
I decided that I had to push the sight to the left before every shot. That would hopefully return it to the same place every time, giving me the best chance to get good results from it despite its looseness. Then, I shot the next group with more Chinese domes. I forgot to move the sight for 2 of the 10 shots. Nevertheless, this group measures 1.328 inches between centers, which is a significant improvement.
Ten shots went into 1.328 inches at 25 yards. I never thought I’d be happy with a group like this, but I am! It’s interesting that perhaps 6 of the pellets in this group went into a much smaller cluster near the center of the main group.
After this target, I adjusted the rear sight once more and then shot a third 10-shot group with the Chinese pellets. I only forgot to push the sight once this time, on shot 9. The group measures 1.597 inches between centers, which is the largest group shot this day with this pellet. Perhaps I was tiring?
Ten shots went into 1.597 inches at 25 yards. I never thought I would be happy with a group like this, but I am! While it’s tempting to think that the shot on the left was the one that I didn’t push the rear sight for, I cannot say that for certain.
It was time to try the Falcon pellets again. In the last test, 10 Falcons made a group that measured 1.497 inches between centers at 25 yards. This time, 10 went into 1.783 inches. Obviously that’s a lot larger; but if you examine the group, you’ll see that 7 of the pellets went into just 0.692 inches. Taking that and the other group-within-a-group that I shot with the Chinese domes, I came to the conclusion that this Fast Deer may really be accurate but is being hindered by its open sights. The next test of this rifle must therefore have a scope mounted.
I do not like testing airguns that have been given every chance and still haven’t performed. Every once in awhile, something anomalous like this Fast Deer jumps out at me and needs to be investigated further. If it hadn’t been for my going over the results of this rifle so close to the time I reported similar results from the Diana 25 smoothbore, I might never have given this rifle its second chance today. Now, we’ll all get to see if that was worth it.
I admitted up front that this test demonstrated that the pellet was only part of the reason the Fast Deer has been inaccurate at 25 yards. From today’s test, we might conclude that the poor rear sight that moves is also affecting the outcome. In the next test, I need to make sure that the scope is locked down solid, so the rifle is free to be as good as it can be.

Benjamin Marauder .177 caliber: Part 1
Secrets of loading the Benjamin Marauder magazine
Fixing a Marauder magazine
Benjamin Marauder .25 caliber: Part 1
Benjamin Marauder .25 caliber: Part 2
I told you this report was going to be a different kind of test, and today I’ll prove it. I shot the .25-caliber Benjamin Marauder off a rest at 25 yards, but the purpose was not to learn if the rifle is accurate — I already knew it is. And 25 yards is hardly long enough to show the accuracy potential of this powerful PCP.
No, I told you that I would be searching for the most accurate pellets in this rifle. You see, unlike .177- and .22-caliber guns, the big .25 doesn’t have that many accurate pellets. Going into this test, I only knew of 3 — the H&N Baracuda (also branded as the Beeman Kodiak), the Benjamin dome and the JSB Exact King. Other .25-caliber pellets I’ve tested were not accurate enough to be considered. Today’s test is to establish that the 3 good pellets are still good in this test rifle and to see if there’s another good pellet or 2 out there.
The rifle is now scoped with the UTG 6-24X56 AO scope with illuminated reticle, which I’m also testing for you. I won’t get into that evaluation in this report, but I will use this test to report on that scope. This scope has high rings that come packaged with it.
Testing pellets rapidly
Time is a commodity in short supply around here. It takes a long time to test something, then pictures have to be taken and it takes even more time to write it up. Normally, I shoot 10-shot groups for accuracy, but I told you I was going to do things differently today, and this is where it starts. Instead of shooting 10-shot groups (or 8-shot groups because the .25 Marauder circular magazine only holds 8 pellets), I decided to shoot 4-shot groups. The results of those groups would tell me which pellets were worth testing more closely. But testing more closely won’t be at 25 yards. It will be out at 50 yards.
Since I’d just mounted the scope, I had to sight-in the rifle, and for that I loaded a full magazine with 8 H&N Baracudas. Sight-in took just 2 shots, so the first group for the record was 6 shots instead of 4. As predicted, it was a tight 0.376 inches at 25 yards. Of course, some of that is due to the lesser number of shots, so bear that in mind. Also, bear in mind that a group of .25-caliber pellets will look much larger than the same size group of .177-caliber pellets.
JSB Exact King and Benjamin dome
Next, I shot 4 each of the JSB Exact Kings and Benjamin domes. Both performed exactly as expected. The 4 Benjamin domes went into 0.196 inches. Of course, I would expect this group size to double with 10 pellets, but it’s still the kind of accuracy I was looking for.
I shot the first 3 JSB Exact Kings into a very tight 0.11-inch group, but the fourth shot was a called pull to the left. It opened the group to 0.383 inches; but since I know that I pulled the shot, it doesn’t phase me. This pellet also made the cut for more testing.
Three JSB Exact Kings went into 0.11 inches at 25 yards. That’s the larger hole on the right. A pulled fourth shot that was called opened the group to 0.383 inches, but that doesn’t bother me. This one is a keeper, as well.
The only other pellet that showed promise in this test was the Predator Polymag. Four of them went into 0.274 inches at 25 yards. That’s good enough to earn a chance to shoot at 50 yards in my book.
The other pellets
As I said before, the .25-caliber pellet is not as uniformly accurate as the .177 and .22. Until this test, only the first 3 pellets I shot had shown any promise. Now, we have a fourth. To show you what some other pellets look like in comparison, here are 3 more that didn’t make the cut.
The results of 4 RWS Superdome pellets tell the story of the .25 caliber very well. Four went into a group that measured 1.378 inches between centers. You can clearly see there’s no need to shoot 10 pellets, when just 4 make a showing like this.
Next, I tried the pellet that was the best .25-caliber pellet for many years in the 1990s. Until the H&N Baracuda came out in .25 caliber, the 20-grain Diana Magnum was the pellet people chose for accuracy. Certain individual guns may have done better with other pellets, but the Diana Magnum was considered the best all-around .25-caliber pellet of its day.
Not surprisingly, Diana Magnums turned in the smallest group of the three pellets that were not selected to go on to longer-range testing. Four went into 0.588 inches at 25 yards.
Beeman Ram Jet
Another pellet that has left the stage is the .25-caliber Beeman Ram Jet. It was supposed to be a domed pellet that also performed like a wadcutter, but accuracy was never this pellet’s strong suit. Four of them made a 0.769-inch group at 25 yards.
I hope from these results that it’s clear why I went with 4-shot groups instead of 10-shot groups. I never planned on testing the .25-caliber Marauder at 25 yards, except to prepare for the 50-yard test, which will be next. I think you can see the clear differences between the pellets that were selected and those that missed the cut. More than any other caliber, the big .25 is an all-or-nothing caliber. And there aren’t that many pellets to choose from.
One more thing I want to report today is how the trigger now performs. I adjusted it before this test and got it exactly where I want it. I won’t say that it’s better than the trigger on my .177 Marauder, but it’s just as good. The Marauder trigger is something Crosman can be proud of, for it surpasses most PCP adjustable triggers I’ve tested. This one now has a positive stop at stage 2, followed by a very light, crisp break. It allowed me to hold very precisely and know when I pulled my shots, which only happened once during this session. This trigger will certainly do!
Next, I plan to shoot the rifle at 50 yards with these 4 pellets. That should give us a good idea of the long-range capability of the rifle. If the results suggest it’s capable, I may attempt a 100-yard test, as well. I need for the shooting conditions to be perfect to do it; but if they are, we may see the real potential of the big Marauder.

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.
