Ruger Airhawk Combo
Ruger Air Hawk combo is very popular.

Parts 1 and 2
Part 3

This report covers:

• Doing something different
• Tightened the barrel joint
• Sight-in and the first group with Hobby pellets
• Air Arms Falcon pellets
• RWS Superdome pellets
• H&N Baracuda Match pellets
• JSB Exact Express pellets
• Crosman Premier 7.9-grain pellets
• Alternate hold
• Conclusions

I started this test in July but have laid off for several weeks. Thanks for bearing with me. Today, we’ll look at the accuracy of the Ruger Airhawk combo at 10 meters.

I’m looking at this combo because a number of readers say they really like the rifle. Of course, it’s been compared to an RWS Diana 34, but I wouldn’t go that far. Yes, there are similarities between the two rifles, but they’re not identical. And each has its own unique firing characteristics – and we’ll all learn a lot about those as I fire the rifle for accuracy using the open sights.

If this rifle proves to be accurate, it’ll be a best buy, given the price of just $130. I know my test rifle is shooting slower than the advertised velocity, but I plan on testing the velocity, again, after the accuracy test, so don’t give up just yet.

Doing something different
I’m changing the way I test air rifles in an attempt to make some progress faster than in the past. I’ll shoot just 5 shots at 10 meters off a rest with each pellet and then look at the group. If the group shows promise, I will come back to the pellet. If not, I’ll move on. That way, I’ll be able to test more pellets in the same time.

I’ll also test at least 2 different variations of the artillery hold — the 2 that have proven the most successful over the years. If one seems better than the other, I’ll continue to use that hold for all the other tests.

Tightened the barrel joint
I noticed last time that the barrel joint wasn’t tight. This barrel has a bolt that can be tightened, so I removed the action from the stock and tightened the barrel pivot bolt. When I was doing that, I noticed that all of them were loose. The inletting of the action in the stock was very tight — fully the equal of anything made in Europe. That gives me hope this rifle will be accurate.

Sight-in and the first group with Hobby pellets
I sighted-in the gun and shot the first group with RWS Hobby pellets. Sight-in amounted to just one shot that told me the rifle was on target from the factory.

I’m showing the sight-in shot along with the first group for two reasons. First, it shows how low the first shot was, yet I knew I’d be okay because I was shooting from just 12 feet. I knew the group would hit the paper higher. Second, it shows how much the shots climbed on target when I shot from 10 meters. This lesson demonstrates that you cannot sight-in a gun for anything under 10 yards and expect it to be on at any other distance. Even 10 meters is too close to sight-in a rifle if you expect to ever hit things at 15 yards and beyond. The sights are too close to the target, and the angular separation from the bore is too great when you’re this close.

I held the rifle on the flat of my off hand with the triggerguard touching the heel of that hand. The group of 5 Hobbys measures 0.678 inches between centers. This is too large for a 10-meter group, so Hobbys are out of consideration.

Ruger Airhawk Combo sight-in and Hobby group
The sight-in shot hit below the bull, telling me the rifle was sighted-in. Five RWS Hobbys made a 0.678-inch group at 10 meters. Not good enough!

After this group, I adjusted the rear sight 7 clicks to the left but didn’t touch the elevation. The sight remained in that setting for the rest of this test.

Air Arms Falcon pellets
Next, I tried Air Arms Falcon pellets. Falcons hit the target well-centered but much lower than the Hobbys. Five pellets went into a group that measures 0.493 inches between centers. While that isn’t as good as I’d like to see at 10 meters, it does show some promise. I’ll probably shoot Falcons from 25 yards, as well.

Ruger Airhawk Combo Falcon group
Five Air Arms Falcon pellets went into 0.493 inches at 10 meters. This is interesting.

RWS Superdome pellets
Next, I tried RWS Superdomes. They gave me a puzzling result. Four of the 5 pellets went into 0.506 inches, but the final shot opened the group to 0.906 inches. That might have been an aiming error; but at 10 meters, I usually don’t make mistakes that large. I might try these again, but not if I find 2 other pellets that are better.

Ruger Airhawk Combo Superdome group
Five RWS Superdome pellets went into 0.906 inches, but 4 of them are in 0.506 inches. Interesting, but not good enough.

H&N Baracuda Match pellets
Next, I shot 5 H&N Baracuda Match pellets. Sometimes these pellets that seem too heavy for a gun will surprise you with their accuracy, although I have to say that happens more with heavy .22-caliber pellets than with .177s. It certainly didn’t happen this time. Five Baracuda Match went into 1.372 inches. Although 3 pellets are close, I don’t think this pellet is right for this rifle.

Ruger Airhawk Combo Baracuda Match group
Five Baracuda Match pellets in 1.372 inches at 10 meters. Not the pellet for this rifle.

JSB Exact Express pellets
Five JSB Exact Express pellets were next. I have to confess that, while I like JSB pellets a lot, I’ve never had any luck with the Express pellet in either caliber. Today was no different. Five went into a 1.466-inch group that proved to be the largest of the test. Definitely out of the running for this rifle!

Ruger Airhawk Combo JSB Express group
JSB Exact Express pellets made the largerst group of the test — 5 in 1.466 inches at 10 meters.

Crosman Premier 7.9-grain pellets
I felt I had to try the 7.9-grain Crosman Premier pellet that’s often the best in some rifles. And I got an interesting result. The first pellet hit the target high and near the center of the bull. Then the next 4 dropped over one inch and grouped in 0.411 inches.

Ruger Airhawk Combo Premier lite group
As a 5-shot group, Premier lites were not impressive, but only the first shot is apart from the group. Four went into 0.411 inches at 10 meters. This is a pellet worth testing further.

This group is small enough to interest me, so I shot a second group of 10 pellets. They landed in 0.746 inches, which is okay, but not the best. However, if you look at the group, you can see that 6 of the 10 pellets went into a much tighter group that’s a single hole measuring 0.357 inches between centers. I know that aiming errors can put me off by as much as these 4 outlying pellets at 10 meters, so this group gives me confidence that the Airhawk can really shoot.

Ruger Airhawk Combo Premier lite 10-shot group
Ten Premier lites went into 0.746 inches at 10 meters, but 6 of them went into just 0.357 inches. That looks promising!

Alternate hold
I then tried the same Premier lite pellets with my off hand slid forward so I could feel the beginning of the cocking slot against my palm. Now that I know this is a good pellet, I can try different things like this. Five pellets went into 0.852 inches, which isn’t good — but look where 3 of them went! That hole is a group measuring 0.069 inches! I don’t think that was due to the different hold, but I do think it tells me this rifle can really shoot and that the Premier lite pellet is right for this gun.

Ruger Airhawk Combo Premier lite second group
Using an alternate artillery hold, 5 Premier lites went into 0.852 inches. While that isn’t so good, 3 of those pellets went into 0.069 inches. I think the rifle can shoot, and this pellet is the right one – but the first hold is best.

Conclusions
Edith spotted the fact that I may have skewed the test results by not seasoning the barrel for each pellet. I guess that’s the down side of shooting so many 5-shot groups. It does bring up a good point. I think that when I move back to 25 yards, I’ll season the barrel with 20 shots per pellet before shooting the first 10-shot group.

She also suggested that I do a seasoned barrel vs. unseasoned barrel accuracy test. There are enough of you who believe in the seasoning process, so that makes such a test worth the effort.

Crosman 2240 conversion to air: Part 4

WARNING: This conversion changes the operation of the pistol to use air at up to three times the pressure it was designed for. The parts that are installed are strong, but there are other parts in the gun that aren’t changed and could fail when subjected to the higher pressures. Pyramyd Air advises anyone making such a conversion to exercise extreme caution.

Today, we’ll look at the accuracy of the 2240 on air at 25 yards. I’ve installed a 14.50-inch Crosman barrel on the gun, which boosted the velocity, as we saw last time. It also may have boosted the accuracy. Let’s find out.

The UTG Pro 6-Position Adjustable Stock has been remounted using the R.A.I. adapter. So, this is now a handy carbine.

I’m filling the pistol to 2250 psi, because I learned that was necessary when using the factory valve and a heavier striker spring. I get exactly 10 good shots per fill, which works well with my 10-shot groups.

For a sight, I installed the Tech Force TF90 dot sight that was used to test the Hakim rifle at 25 yards. We saw in that report how well this sight works, so it should work just as well on this carbine-sized gun I’ve assembled.

I sighted-in with 5 shots at 12 feet, and the gun was ready to shoot at 25 yards. I’ll show the sight-in target and explain it, so you can understand how this close sight-in works.

Sight-in at 12 feet
I sight-in at 12 feet because it’s safer. I know I’ll be on paper that close to the target, and I also know where the pellet needs to strike to be on at 20 yards. I used to sight-in all the rifles we sold at AirForce Airguns this way and was always on-target when I backed up to 23 yards. To learn more about this method, read this article.

What I’m looking for is the pellet landing in line (left and right) with the center of the bull, but as far below the center as the center of the sight is above the center of the bore. In other words, if you were to walk up to the target until the muzzle was touching the paper and center the dot (in this case) on the bull, where would the pellet strike the paper?

When you’re 10-12 feet back, the impact point doesn’t change much from that. But when you back up to 20 yards (20-30 yards, actually) the pellet rises up on the paper and ends up close to the aim point. It isn’t exact, but it’s the fastest way that I know to sight-in a pellet rifle.

My sight-in pellets were hitting the target a bit high, but not too high. Once they were centered, I left the sight where it was set and just backed up. I sighted-in with Crosman Premiers.

Crosman 2240 air conversion long barrel sight in
The first 3 pellets hit to the left of center. I adjusted the sight, and shot 4 hit to the right of center. I adjusted back to the left, and shot 5 was close to center. These are hitting too high at 12 feet, but I’ll use the setting as it is.

Back to 25 yards
The first group was fired with 14.3-grain Crosman Premier pellets. The first 3 pellets hit high and right of center. I don’t know how the rest of them hit, but you can see this is a fairly well-centered group of 10 shots. It measures 0.918 inches between centers, which isn’t too bad for a small gun like this at 25 yards. Remember — I’m shooting 10 shots instead of only 5.

Crosman 2240 air conversion long barrel Premier target
Ten pellets made this 0.918-inch group at 25 yards. This is pretty good!

Again, I must comment how nice and clear the TF90 sight is. It really holds a tight group – even though the target appears very small. That makes it a confidence-builder.

Next, I tried the JSB Exact Jumbo RS pellet. These often do well in lower-powered airguns. Remarkably, they went to the same point of impact as the Premiers. That means I don’t have to change the sight settings when using either pellet. This time, 10 RS pellets made a 0.763-inch group! That was very good, I thought. Especially given that I was using a dot sight!

Ten JSB Exact RS pellets went into 0.763 inches at 25 yards. This is very good!

End of the test
I’d planned on trying Beeman Devastator pellets next; but when I filled the gun, I noticed a leak at the joint of the HiPAC tank and the pistol’s tube. It was a fast leak and obviously the o-ring wasn’t doing its job. I tried oiling the gun with silicone chamber oil and refilling it, but the leak didn’t stop. So the test was over. I have to find out the problem and fix it if I can.

I do note that the pistol leaked down to 1750 psi and stopped. When I refilled it, the leak was much slower, so the oil may have done something. I think the o-ring and groove need to be cleaned and the tank installed again. But we’ll see.

At any rate, today’s test shows promising accuracy. It may not have been complete, but I’ll return to test the gun again at 25 yards. I plan to mount the TF90 on the Crosman 1077 next, so it may be a while before I get back to the 2240.

Ft. Worth airgun show update
The hotel is filling up fast for the show. Don’t forget to come to the reception at the hotel even if you aren’t staying there. It will be 7 p.m. to 8:30 p.m. Friday evening. Nothing fancy — just a chance to meet and talk about airguns before we set up Saturday morning.

I’ll be taking a caravan of people out to the range Friday afternoon from the hotel at 4 p.m. The range will be open earlier for people who want to get out there by themselves, but please tell me you are going, because this range is private. They need to know you’re coming or the gate will be locked.

We plan to start the door prize and raffle drawings very early after the show opens, and they’ll be held periodically throughout the day. Get there early and buy your raffle tickets for a chance to win a Walther LGV Competition Ultra, an AirForce Airguns CondorSS or a Hatsan AT44-10 Long QE! Since this show will probably not top a thousand attendees, you’ll have a real chance to win one of these fabulous rifles. And everyone who pays admission gets a chance to win an Air Venturi Bronco and a Benjamin Trail NP2 door prize!

Boot Campaign
Another group coming to the show is the Boot Campaign — a Texas-based nonprofit organization dedicated to the military (past and present) and their families — cultivating awareness, promoting patriotism and providing assistance.

Also, American Airgunner TV host Rossi Morreale will be attending the show, as he’s interviewing the ladies from the Boot Campaign.

I’ll have more news about the show as it develops.

Crosman 2240 conversion to air: Part 3

Crosman 2240 air conversion long barrel
The steel breech and longer barrel increase the 2240′s length dramatically.

This report covers:

• Installation of a steel breech and longer barrel
• Easy steps
• First velocity test
• Crosman Premier pellets
• RWS Hobby pellets
• RWS Superdome pellets
• What have we learned?
• Replace the striker spring with a heavier spring
• Crosman Premier pellets
• RWS Hobby pellets
• RWS Superdome pellets
• Evaluation to this point

This is the third look at converting a Crosman 2240 CO2 pistol to run on high-pressure air. In the last report, we saw how the conversion works with the factory barrel and factory striker spring. Today I will install a longer barrel with a steel breech and see what that does. Then I will add a stronger striker spring and see what that does.

Installation of a steel breech and longer barrel
Installing a Crosman steel breech and a Crosman 14.50-inch barrel on the 2240 pistol took all of 10 minutes. Four screws were removed, and both the plastic breech and barrel came off. After the detailed disassembly you saw in Part 1 of this report, this modification was a walk in the park.

Easy steps
The new breech was made by Crosman and sold by Pyramyd Air for $38, plus shipping. The barrel was also made by Crosman, and I bought it off eBay for $37 plus shipping. Together, these two parts have added about $85 to the cost of the gun, on top of the $65 for the air conversion that was given to me by Rick Eutsler. That’s an additional $150 I’ve put into this gun. And I’m not counting the adjustable stock and adapter that turns this pistol into a carbine. I’m not complaining about the cost, but don’t let anyone say this is a cheaper route than buying a Benjamin Discovery outright. What you get with this conversion is the time you need to make the investment. You can do this in easy steps.

First velocity test
I left the factory striker spring in place for this first test and pressurized the pistol to 2000 psi. Then, I shot the same 3 pellets I’ve been testing all along:

14.3-grain Crosman Premier pellets
11.9-grain RWS Hobby pellets
14.5-grain RWS Superdome pellets

Below are the velocities on CO2 for the factory gun; then the velocities for the factory gun with the high-pressure air conversion; and finally the velocities for the gun with the steel breech, longer barrel and factory spring — all operating at 2000 psi.

Crosman Premier pellets
CO2 avg…………..Air in factory gun average…………..Air in long barrel average
448 f.p.s…………………..486 f.p.s………………………………………517 f.p.s.

I got 15 shots with this pellet and the longer barrel. They ranged from 504 f.p.s. to 524 f.p.s.

RWS Hobby pellets
CO2 avg…………..Air in factory gun average…………..Air in long barrel average
482 f.p.s…………………..526 f.p.s………………………………………564 f.p.s.

This pellet gave me 18 shots from a 2000 psi fill with the longer barrel. They ranged from a low of 548 f.p.s. to a high of 573 f.p.s.

RWS Superdome pellets
CO2 avg…………..Air in factory gun average…………..Air in long barrel average
455 f.p.s…………………..483 f.p.s………………………………………525 f.p.s.

Superdomes gave 14 shots on a 2000 psi fill. With the longer barrel, the low was 516 f.p.s. and the high was 534 f.p.s.

What have we learned?
Obviously, the pistol shoots faster with the longer barrel and no other changes. Adding the steel breech does strengthen the rear of the barrel, but it doesn’t add anything to velocity.

All 3 shot strings posted above started out slow and increased as the shots were fired. So, the pressure curve is about ideal when the fill is at 2000 psi.

The velocity increase from CO2 in the standard pistol to high-pressure air in the longer barrel is very significant. But by leaving the factory striker (hammer) spring in the gun, we’re not getting all this conversion has to offer.

Replace the striker spring with a heavier spring
The kit Rick Eutsler sent me contained two striker springs — both of which are stronger than the factory spring. I removed the factory spring and installed the spring that was the weakest of the two, though stronger than the factory spring. I wanted to keep the fill pressure at 2000 psi, and the strongest spring would not be the way to do that.

I filled the gun to 2000 psi and proceeded to shoot Crosman Premiers. Here are the first 8 shots.

581
577
576
575
578
576
570
568

The velocity dropped with almost every shot. Yes, there are a few exceptions, but the trend is generally down. What this means is that the new spring is too strong for the fill pressure of 2000 psi. The pistol wants to start at a higher pressure with this spring.

I decided to fill the gun to 2250 psi. This is above the maximum I wanted to use, but it illustrates the relationship I just mentioned and is worth a look. Let’s look at the velocities at this pressure.

Crosman Premier pellets
588 f.p.s. average, low 582 f.p.s., high 594 f.p.s.

Compare the above to the average velocity with the factory striker spring and longer barrel, which was 517 f.p.s. This is a huge increase of 71 f.p.s. The stronger striker spring gives more of a boost than the longer barrel by itself. But — and understand this — without the longer barrel, the stronger spring would only waste more air. This is a modification that requires all the components to work together. You can’t just pick one item and be done with it.

RWS Hobby pellets
640 f.p.s. average, 632 f.p.s. low, 646 f.p.s. high

The remarks are the same for Hobbys as they are for the Premiers.

RWS Superdome pellets
590 f.p.s. average, 580 f.p.s. low, 596 f.p.s. high

Same remarks apply to this pellet as to the others.

All three pellets gave me maximum shot strings of 10 shots when set up this way. Obviously, more air is being used and the volume of the reservoir has remained the same.

Evaluation to this point
We’ve taken this Crosman 2240 pistol from one power on CO2 to a much higher power with high-pressure air, a longer barrel, a stronger spring and a steel breech. These modifications cost a total of $150 over the cost of the initial pistol ($60). Is it worth it?

The answer will depend on who’s talking. Some shooters enjoy putting their hands on the parts of their airguns and making their own creations. Others look at the total investment and just want something that shoots well for the least amount of money. This 2240 modification is not for the latter group, because we still have to add a $60 RAI adapter and a $60 UTG Adjustable Stock. That brings the cost of the gun we’re modifying to a total of $330.

The next step is to try this modification for accuracy. For that, I’ll attach the adapter and stock, again. I think it has to be tested to at least 25 yards with a scoped gun.

Hatsan AT44-10 Long QE: Part 5

Hatsan AT44S-10 Long QE
Hatsan’s AT44S-10 Long QE is packed with features for airgun hunters.

This report covers:

• Inconsistent shots?
• Most accurate pellet?
• 100 yards means scope adjustments
• JSB Exact Jumbo heavy pellets
• Crosman Premier pellets
• H&N Baracuda Green pellets
• Gamo Hunter pellets
• Call it a day
• Conclusions
• Pyramyd Air sale

Today is a test of the Hatsan AT44-10 Long QE at 100 yards. I don’t do this very often for many reasons; but when I find a PCP that’s exceptionally accurate at 50 yards, I feel it’s worth testing at the greater distance. It takes a perfect day for this test because any wind will push the pellet around. We don’t get many windless days here in Texas, but this past Wednesday was one of them. It was so calm that dandelion fuzz would fall straight down.

You also know from reading this blog that groups do not always open in linear fashion as the distance increases. A rifle that shoots a half-inch group at 50 yards will not automatically shoot one-inch groups at 100 yards — even though the day is perfect.

Inconsistent shots?
While testing this rifle, I’d seen that the first 10 shots could be less accurate than the second 10. They sometimes contained fliers that didn’t seem to exist in the second group. Yesterday, blog reader Jerry in Texas asked me why one shot out of 10 from his Benjamin Marauder was dropping in velocity by over 250 f.p.s. I told him I thought some PCP guns do that in certain places in the power curve. I saw evidence of that on the 50-yard range and again at 100 yards, as I’ll show you.

Most accurate pellet?
I also hedged my bets by taking several pellets to the range that hadn’t been tested in this rifle before. I was getting such great performance at 50 yards from one pellet in particular — the 18.1-grain JSB Exact Jumbo Heavy — that I sort of stopped testing other pellets. That’s not very scientific of me, though it’s very much in keeping with being a gun crank. So, I took some other pellets along and gave them a try at 100 yards — even though they’d not been tried by me before in this rifle.

100 yards means scope adjustments
I knew the pellet would drop a lot going from 50 yards to where the rifle was sighted to 100 yards. I guesstimated the drop would be at least 12 inches, which would be 48 clicks on the quarter-minute elevation knob to bring things back up. But when I adjusted the scope, I stopped at 40 clicks because you never know if the clicks are exactly quarter-minute or if that’s just an approximation. As it turned out, both my guesstimate and the adjustments were close to correct, and I had to adjust the scope another 16 clicks up to get close to the point of aim.

JSB Exact Jumbo Heavy pellets
The first pellet up was the 18.1-grain JSB Exact Jubo Heavy that had given me a group of 10 in 0.522 inches at 50 yards. If any pellet was going to excel in this rifle at 100 yards, I felt this one had the best chance. Alas — the best-laid plans….

The best I was able to do with this pellet was 10 in about 3 inches. I shot the same pellet in both the first 10 shots and the second 10 shots per fill with pretty much similar results, except there was a flier in the first group. I’m not going to show you those groups because they don’t help the report and also because the first group fell below the target paper and hit the 2×4 backer paper I always use when I’m not sure where the pellets are going.

At this point, I decided to punt — as in testing something I hadn’t tried before. One reader had recommended trying the 15.89-grain JSB Exact Jumbo pellets, and I thought it was a good choice. It happens to be one of my favorite .22-caliber pellets, and I normally would have tested it at 50 yards; but when the heavier JSB did so well, I decided to just shoot it to the exclusion of all others.

I refilled the rifle with air and loaded 10 JSB Exact Jumbos into the circular clip. The first group was very telling. Nine out of 10 pellets landed in a 1.668-inch group, but the first shot hit about 4 inches above the top of this main group. Remember what I said about inconsistencies in the first 10 shots after a fill?

Hatsan AT44S-10 Long QE JSB Exact group 1 100 yards
Nine of the 10 JSB Exact pellets landed in this 1.688-inch group at 100 yards. The first shot was 4 inches higher. This is a very good group for any pellet rifle at 100 yards.

After that group, I refilled the clip and shot a second group with the same pellet. This time, all 10 went into 2.385 inches. I know that doesn’t sound very good, but I ask you to reserve your comments until you have shot some 10-shot groups of pellets at 100 yards. It isn’t easy! And guns that group in a half-inch at 50 yards do not necessarily group in one inch at 100 yards.

Look at the shapes of these holes. Many are oval in shape, which indicates they didn’t go through the paper straight-on.

Hatsan AT44S-10 Long QE JSB Exact group 2 100 yards
Here are 10 of the same JSB pellets in a 2.358-inch group. These oval holes show some evidence of a tilt on axis.

Crosman Premier pellets
One of the most accurate .22-caliber pellets is the domed Crosman Premier that comes in the brown cardboard box. Sometimes, they’re the most accurate, and other times they’re among the top 3. But in PCPs they don’t do as well — especially when the PCP is more powerful such as this Hatsan. And this was no exception to that rule, as Premiers couldn’t stay inside 6 inches at 100 yards. I didn’t even complete a group with them after seeing the first few shots land so far apart.

I’d planned on trying Eun Jin pellets, as well; but when I started loading them, I discovered that the tin I picked up were .25-caliber pellets.

H&N Baracuda Green pellets
The next pellet I tested was the H&N Baracuda Green. While lead-free pellets are not that accurate as a general rule, Baracuda Greens are an exception. In the Hatsan, they managed to put 10 shots into 5.25 inches, with 9 of those shots in 2.988 inches. That’s pretty good for lead-free pellets; and, yes, this was the first group of 10 after a fill.

Gamo Hunter pellets
The last pellet I tried was the Gamo Hunter. While I have very little experience with this pellet, I do recall it working well in one spring rifle years ago. But it was not suited to the Hatsan AT44. I didn’t see where the first Hunter struck the target; but I saw the second pellet’s flight through the scope, and it was a wild spiral curve to the right that landed a foot off the target! Clearly this rifle is not suited to shoot Gamo Hunters.

Call it a day
After this last attempt, I decided to call it a day. The shooting had worn me out by this time. I think it’s clear that of the pellets I’ve tested so far, the JSB Exact 15.89-grain Jumbo is the best. Out to 50 yards it may do no better than the heavier 18.1-grain JSB Jumbo Heavy, but something about this lighter pellet carries it to 100 yards in better form.

Conclusions
I believe the Hatsan AT44-10 Long QE is one of the finest PCP rifles on the market at any price. It has power, accuracy, a great trigger and very quiet operation –all for a wonderful price. If you’re in the market for a good PCP, I would put this one on your short list.

WARNING: This conversion changes the operation of the pistol to use air at up to three times the pressure it was designed for. The parts that are installed are strong, but there are other parts in the gun that aren’t changed and could fail when subjected to the higher pressures. Pyramyd Air advises anyone making such a conversion to exercise extreme caution.

Crosman 2240 air conversion
My Crosman 2240 has been converted to operate on high-pressure air.

This report covers:

• Before filling the first time
• Shooting the gun
• Crosman Premier pellets
• RWS Hobby pellets
• RWS Superdome pellets
• What comes next

Let’s look at what the conversion to air did for the Crosman 2240. Boy, was there ever a lot of discussion on that report! I think this may be one of the all-time most popular subjects on this blog.

Where we are
Here’s where I am with this subject. The 2240 is now converted. I plan to test it with 2,000 psi air today, and I do not plan to go higher. This is a test of what’s out there and some of the things that can be done with a 2240, but I’m not in the business of hotrodding this pistol. Many other folks are doing that very well; so, if you are interested in what’s possible, read what they have to say.

Today, I’m going to test the pistol with the conversion but with the stock striker spring still installed. In other words, if you simply screwed the tube into the gun and did nothing else (the front sight still has to come off to clear the tube), this is what you’ll get. I did change the face seal, which is why I disassembled the pistol in the previous report; but that wasn’t strictly necessary, since I am pressurizing to only 2,000 psi. I did it just to show how the entire kit is installed.

Before filling the first time
Before filling the gun, which is now done through the male Foster nipple on the end of the air tube, I put several drops of silicone chamber oil into the fill nipple. It came to me bone-dry, and I wanted all the seals inside the unit to get a coating of this oil. Then, I connected the gun to my carbon fiber air tank and slowly filled it to 2,000 psi. I say slowly, but as small as this air tube/reservoir is, it fills pretty fast. It probably took only 15-20 seconds to fill it all the way. You want to go as slowly as as possible to keep heat from building.

When I bled the air connection in the hose, the inlet valve in the air tube remained open and all the air bled out. So, I refilled it and bled it a second time. This time, it sealed as it should — thanks to the oil, I believe.

Shooting the gun
It was now time to test the gun. I had no idea what it was going to do, but I left my hearing protection off to hear if the first shot was loud. It wasn’t. Perhaps the gun is a little louder than it is when using CO2, but the difference is not that great. Of course, I used eye protection for the chronographing session, because the pellet trap is so close. I use a trap with duct seal to keep the rebounds down and the noise to a minimum.

Crosman Premier pellets
The first pellet I tested was the 14.3-grain Crosman Premier dome. I should add that I shoot only the pellets from the cardboard box, which is why I link to them, only. We were informed several months ago that Crosman planned to stop selling Premiers in the cardboard box and I stocked up on them. But I see they’re still available.

Back in 2010, I did a test of the CO2 2240 pistol, so I have the recorded velocities for this exact pistol on CO2. It averaged 448 f.p.s. with Crosman Premiers. On 2000 psi air, the first shot was 468 f.p.s. It increased to a maximum of 492 f.p.s. by shot 7 and dropped back to 466 f.p.s. by shot 15. At the end of the string, the gun was still holding 1200 psi of air pressure. The average velocity of 15 shots was 486 f.p.s., which means air boosted the average velocity of this pellet by 39 f.p.s.

RWS Hobby pellets
Next up were 11.9-grain RWS Hobby pellets. When the pistol was running on CO2, these pellets averaged 482 f.p.s. On 2000 psi air, they started at 515 f.p.s. and increased to 537 f.p.s. by shot 9. The velocity droped back down to 511 f.p.s. by shot 16. The average velocity for this string of 16 shots was 525 f.p.s. — a 43 f.p.s. increase on air. The remaining pressure was 1200 psi, once again.

RWS Superdome pellets
The final pellet I tested was the 14.5-grain RWS Superdome. When the pistol ran on CO2, Superdomes averaged 455 f.p.s. On 2000 psi air, they started at 470 f.p.s. and drifted up to 495 f.p.s. by shot 7. They dropped back down to 467 f.p.s. by shot 16. The average velocity was 483 f.p.s., an increase of 28 f.p.s. over CO2.

Notice that the gun performs similarly, regardless of what pellet was tested. The curve starts out slow, builds to the maximum quickly and then drops back to the starting point just as quickly. The three pellets gave a total shot count of 15, 16 and 16, respectively.

What comes next?
I can’t test the pistol for accuracy as it is right now because the front sight has no clearance to be re-installed. And the plastic 2240 receiver does not have a scope base on the receiver. Decision time.

I could get a steel breech for the 2240 from Pyramyd Air. While it will not accept the 2240 rear sight, it does have 11mm dovetails for a scope. That’ll work with the barrel that’s on the gun right now; but if I get a longer barrel, I’ll get a little more velocity from this same setup. So, I ordered a 14.5-inch barrel from an eBay vendor.

There are a number of different ways this can go with these parts, so I will wait to see what seems best once I have them.

Hatsan AT44-10 Long QE: Part 4

Hatsan AT44S-10 Long QE
Hatsan’s AT44S-10 Long QE is packed with features for airgun hunters.

This report covers:

• Fast becoming a favorite
• Accuracy test
• Stunning first group!
• Tried RWS Superdomes
• Finish with JSB pellets
• Overall evaluation
• 100-yard test

Fast becoming a favorite
Today, we’re back at the 50-yard outdoor range with the Hatsan AT44S-10 Long QE rifle — an air rifle that’s fast becoming a favorite of mine. I think you’ll see why in this report.

Last time, I showed you some excellent 10-shot groups from this rifle at 50 yards. That day was perfectly calm, and by chance the second pellet I tried turned out to be the one to shoot. The 16-grain Air Arms Diabolo Field pellet delivered some great groups, including one 10-shot screamer that was just 0.624 inches between centers. I resolved to return to the range another day to see if this was just a one-time thing or if the rifle could deliver such stunning accuracy all the time.

Accuracy test
This day was not perfect. There was a little breeze sometimes, but in the beginning it could be waited out. It was only 1-3 m.p.h. when I began shooting. Last time, I learned that the first 10 shots on a fresh fill weren’t as accurate as the second 10, so I filled the rifle to 200 bar and loaded ten 18.13-grain JSB Exact Jumbo Heavy pellets, thinking that I would save the sure-thing Air Arms pellets for the second 10.

Stunning first group!
But my first group was stunning! Nine of the 10 pellets went into 0.552 inches and only shot 8 strayed from the main group. It enlarged the group to 0.916 inches, which is still commendable for 10 shots.

Hatsan AT44S-10 Long QE JSB Jumbo group 1
Nine JSBs in 0.552 inches! Shot 8 opened the group to 0.916 inches, which is still excellent.

Now that the first 10 were shot, I thought the rifle was going to give me a wonderful second group with the Air Arms pellets — but for some reason, it didn’t. Ten went into 1.434 inches, with 5 of them clustered in 0.212 inches. How do I make sense out of that?

Hatsan AT44S-10 Long QE Air Arms group 1
Five shots in that tiny (0.212 inches) hole, but the other 5 went everywhere else (1.434 inches)!

The Hatsan is short of breath, and there are only 20 good shots per fill if you’re shooting groups at 50 yards. I filled the rifle, again, and once more I shot the first group of 10 with the JSB Exact Jumbo Heavys. This time, they were a little more open than the first time, but they still managed to all be within 0.676 inches. That’s actually smaller than the first group was, and it’s close to the size of the best group from the previous session (0.624 inches).

Hatsan AT44S-10 Long QE JSB Jumbo group 2
The best group of this session! Ten pellets went into this 0.676-inch group.

The second group I shot was 10 Air Arms pellets, and this time they really opened up. Ten went into 1.334 inches, with 8 of them in 0.824 inches. Apparently, Air Arms pellets were not going to do as well on this day as they had during the previous session!

Hatsan AT44S-10 Long QE Air Arms group 2
For some reason, the Air Arms pellets didn’t want to group together on this day. Ten in 1.334 inches with 8 in 0.824 inches.

Tried RWS Superdomes
I brought some RWS Superdomes along — just to try one more pellet. But the first shot was 14 inches from the aim point (!!!) and the next shot was 6 inches from that! I ejected the clip and removed all the pellets. That’s just wasting air.

Finish with JSB pellets
I filled the rifle once more and this time decided to just shoot the JSB pellets since they seemed to want to do better. The first group of 10 went into a whopping 1.71 inches, which was surprising. The second group of 10 was 1.351 inches apart, and I was now having to fight a growing breeze. I can’t say how much the wind affected the last 2 groups, but it probably had some impact.

Hatsan AT44S-10 Long QE JSB Jumbo group 3
This time the JSBs didn’t stay together too well. Ten went into 1.71 inches. This just shows that sometimes the bear eats you!

Hatsan AT44S 10 Long QE JSB Jumbo group 4
The second group on this charge is a little better — at 1.351 inches. It isn’t always sweetness and light!

Overall evaluation
Based on the results of these two days at the range, I have to say the Hatsan AT44-10 Long QE is one of the most accurate precharged pellet rifles I’ve ever shot. It may not be the most accurate, but it has to be in the top 5!

It’s amazing that an air rifle this powerful is also quiet. It sounds about as loud as my vintage Diana model 27 spring rifle, yet I know it’s producing 35-47 foot-pounds of muzzle energy. And the trigger, while not the absolute finest I’ve ever tested, it still right up there in the top 10.

Hatsan has hit the ball out of the park with this rifle! They’re pricing it to compete with the Benjamin Marauder, and it absolutely kills the more expensive European PCPs in all categories except appearance. But I’m the kind of shooter who wants to hit the target. I don’t care that much what my rifle looks like — as long as it can deliver the mail.

100-yard test
The last time I had a PCP that was this accurate was when I tested the AirForce Airguns Condor SS, and that rifle put 10 pellets into one inch (1.003 inches) at 100 yards. This Hatsan isn’t quite as powerful as the Condor SS, but I’m willing to give it a try at that distance. So, there will be a Part 5 to this series!

Accuracy day…part 2
Today, we return to the Benjamin Trail Nitro Piston 2 air rifle. I think I’ve solved all the mysteries and finally got the rifle to shoot the way it should. You be the judge.

Things that were done
Several things were done to make the rifle ready for today’s test. First, I cleaned the barrel with J-B Non-Embedding Bore Cleaning Compound on a bronze bore brush. To do that, I removed the barrel shroud and the baffles, so access to the barrel was easy. I cleaned from the breech. Since the NP2 has a gas spring, I could leave it cocked as long as I wanted without hurting the spring.

Next, I replaced the 3-9X32 CenterPoint scope that comes with the rifle for an older CenterPoint 3-12X40 scope that has an adjustable objective. Now, I was able to focus the scope on the target at 25 yards. CenterPoint no longer carries this scope that was made by Leapers, but it’s equivalent to this 3-12X40 UTG scope with AO, except that my scope doesn’t have an illuminated reticle.

I shimmed the replacement scope with one thin slice of plastic under the scope tube at the rear ring; because when I removed the factory scope, I noticed that it was adjusted toward the top of its range. I just wanted to make sure the reticle wasn’t floating in the replacement scope because the NP2 has a healthy jolt when it fires. No vibration, but there’s definite movement.

I tightened all the stock screws but found they were mostly tight already. That was when I noticed there’s no front triggerguard screw. The rear screw is the one that holds the action to the stock, and the front has no screw at all — yet there’s a hole in the guard for one. Some companies might be tempted to put a wood screw there to fool you, but that would just invite stripping the hole in the wood stock since the front screw is nearly always the one that gets tightened. Crosman made it foolproof.

06-25-14-02-Benjamin-Trail-Nitro-Piston-2-triggerguard
The front triggerguard screw doesn’t exist. The rear screw holds the action in the stock, and the front hole is blank.

Sight-in
I sighted-in at 12 feet and was on paper with the first shot. In all, I fired four shots to get where I wanted to be at 10 meters. I continue to shoot .22-caliber Crosman Premier pellets in this rifle for this whole test. Once I was sighted-in, I backed up to 10 meters and shot a 5-shot group.

Ten meters
I was still experimenting with holds at this point. I had already spent a whole day shooting the rifle with the factory scope and trying different holds (I didn’t tell you about that day or bother to report it), but a comment from a reader got me thinking. Reader Ben told me to hold the rifle more firmly and also to slide my off hand farther out under the forearm. He reminded me of what I knew but had temporarily forgotten — namely that gas spring guns need a different hold. So, I followed Ben’s suggestions, and they resulted in a 0.319-inch 5-shot group at 10 meters!

Benjamin Trail Nitro Piston 2 10 meter group
Five Premiers at 10 meters went into 0.319 inches.

Okay, that’s just at 10 meters. I know a lot of you do shoot at that distance, and I also know that many people shoot 5-shot groups. This is what the NP2 can do at that distance with 5 Premier pellets.

But you really want to see what it can do at 25 yards. And you want to see 10-shot groups. I adjusted the scope reticle down for 25 yards and started shooting.

The hold
Before I continue, let me describe the hold I’m using today. It’s not an artillery hold. I’m grasping the pistol grip firmly, but not with a death grip. And my off hand is slid out far enough that it’s touching the sling swivel on the forearm. I don’t grasp the forearm tightly, but I do grasp it with my fingers. Having my hand out that far, the rifle doesn’t want to move left or right. So, when the off hand gets settled, the crosshairs stay on target as I relax.

Relaxation is very important with the NP2. Every time I became anxious about where the next shot was going, I threw it wide. But when I relaxed, the shot went to the aim point, as you’ll soon see.

25 yards
The first group of 10 went into 0.931 inches. It’s better than the best group fired in the last test, which tells me that something I did helped out. Cleaning the barrel, tightening the screws, changing the scope or changing the way the rifle is held seems to have made the difference. But I thought the rifle could do even better.

Benjamin Trail Nitro Piston 2 25-yard group 1
The first group of 10 Premiers from 25 yards went into 0.931 inches. It’s better than the best group from the previous test!

The second group is larger than the first, but the 3 pellets that missed the main group were all from my tension. When I relaxed, all the pellets went into the central group. Ten shots went into 1.333 inches, but the central 7 are in 0.656 inches. I think they represent the true accuracy of the NP2. This is the importance of relaxing when shooting this particular air rifle.

Benjamin Trail Nitro Piston 2 25-yard group 2
This group was the most revealing. When I shot totally relaxed, the pellets went to the central group. When I tensed up for any reason, they went wide. Ten shots in 1.333 inches and 7 in 0.656 inches. I believe the NP2 can shoot as well as the central group indicates.

But you’re skeptical, and I would be, too. The concentration needed for every shot (making certain I was relaxed) was tiring me, but this rifle deserved the best I could give, so I shot one more 10-shot group at 25 yards. This time, I relaxed for each shot — the way I would tell someone else to do. You know — do as I say! This time, 10 pellets went into 0.704 inches. This, I believe, represents the level of accuracy of which this particular Benjamin Trail NP2 is capable.

Benjamin Trail Nitro Piston 2 25-yard group 3
This time, I concentrated on the hold and relaxed for every shot. Ten pellets went into 0.704 inches at 25 yards.

Velocity with Premiers
One last thing to do. I told you that the cocking effort had dropped to 32 lbs. after the last accuracy report. With all the shooting I’ve done the rifle now has over 150 shots on the powerplant. I tested it again today, and it still cocks right at 32 lbs. The last velocity test had Premier pellets averaging 793 f.p.s. with a 40 f.p.s. spread. This time 10 Premiers averaged 745 f.p.s. and the spread was only 8 f.p.s.!

I know the gun shoots slower now; but given the wide variation before, I think it’s now settled into what it’s going to do. At 745 f.p.s., the Premier cranks out 17.63 foot-pounds of energy at the muzzle.

Overall evaluation
I think Crosman has made a nice new breakbarrel rifle with the NP2. It doesn’t vibrate, it cocks easier than other gas-spring guns in its power range, the trigger is crisp, the report is quiet and the rifle is accurate. For $250, this is about as nice a spring gun as you can find.

Yes, the power is not at the level Crosman advertises; and yes, the gun does kick — but it still gives you a lot of value for the money spent. The bad press at launch time is going to keep some shooters from giving the NP2 a try. That’s too bad because this is a rifle many of them would like.

I’ve tested this rifle openly and allowed you to see exactly what happened, as it happened. Crosman has sent another NP2 for me to test and I plan on testing that one for you as well. So, it ain’t over yet.

Top-notch springer
Air Arms TX200 air rifle

When it comes to spring-piston air rifles, the Air Arms TX200 Mk III is a favorite of many airgunners, including airgun writer Tom Gaylord. His favorite caliber is .177. While the gun will initially impress you with its beauty and superior craftsmanship, you'll be even more impressed with the incredible accuracy! Tom claims this is "the most accurate spring gun below $3,000." Beech or walnut, left-hand or right-hand stock. Isn't it time you got yours?

All the fun, none of the hassles!
Uzi CO2 BB submachine gun

You've seen tons of movies with guys spraying bullets from their Uzi submachine guns and probably thought it would be a blast. Except for the cost of ammo! You can have all that fun with this Uzi BB submachine gun at just pennies a round. Throw shots downrange for hours on end with all the fun, none of the firearm hassles and a fraction of the cost.
