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.
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?
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.
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.
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.
This report covers:
• Where we are
• 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.

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.
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.
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?
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).
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!
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.
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.
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!

• Rifle was set up
• The hold
• A hunter’s rifle
• Comparison with the first rifle
This is accuracy day with the second Benjamin Trail Nitro Piston 2 rifle — the one Crosman sent especially for this test. We’ve already seen how this second rifle exceeds the power of the first one, so today we’ll see what impact that has on accuracy. As with the first rifle, I’ll shoot 14.3-grain Crosman Premier pellets exclusively in this test.
Rifle was set up
When I unboxed the scope, I found the rings already installed in the correct location, meaning I could install them directly on the rifle. That proves this rifle has been tested and set up before I received it. The scope went on quickly, and I found it was very close to being sighted-in; but the inability to focus the target as close as 25 yards was a hinderance to aiming. I estimate my groups were a quarter-inch larger than they needed to be because I couldn’t see well enough to put the crosshairs on an exact spot. The scope arrived set at 4X, which indicates the rifle was tested at 10 meters or yards before it was sent. At 25 yards, I wanted to see the bull more clearly, so I adjusted it to 9X. But as I said, the focus was off because the scope is parallax-adjusted for a longer distance.
I refined the sight setting and proceeded to test the hold I thought would do best — based on results from the first rifle’s test. I also tried several other holds and hand placements, establishing one thing for certain. The NP2 wants to be held firmly. Do not use the artillery hold. Instead, I found it best to slide my off hand out to almost the end of the stock and grip the forearm firmly. I can feel the forearm screw holds on the tips of my thumb and fingers, so I know my hand is in the same place every time. Any hold that wasn’t firm allowed pellets to rise vertically. I fired probably 30 shots testing just the different holds and pressures.
I then shot three 10-shot groups using the factory scope. The best of them measures 1.104 inches between centers, and the worst measures 1.168 inches. I really tried to do well, but the blurriness of the target did cause my aim to be off.
I felt the factory scope was hindering my best efforts, so I swapped it for an older CenterPoint 3-9X40 with an adjustable objective. This scope is one CenterPoint no longer carries. It’s a simple scope without an illuminated reticle; and other than the larger objective lens and the AO, it’s close to the scope that came with the rifle.
I allowed a day to pass between the first shooting session and the second because too much concentration makes me lose my edge. The next day, I shot another four 10-shot groups, plus some more sighters to get the scope shooting where I wanted. On this second day, my groups ranged from 0.895 inches between centers to 1.483 inches. I learned as I went, refining the hold that seems to be critical with the NP2. The worst group, for example, came when I experimented with the firmness of the offhand grip.
By the end of the session, I knew what this rifle wants — a firm hold of the off hand as far out on the forearm as you can comfortably hold and a firm hold of the pistol grip. Pull the butt into your shoulder firmly. This is not a death grip — just a firm hold, and it seems to be what the NP2 wants.
I’m not through with this rifle, yet. Each one of my second-session groups contains a large cluster of shots that are very close, then some strays that wander off — usually down, but not always. I think I’m close to understanding what this rifle wants, but I’m not there yet. I think it needs a very repeatable offhand grasping pressure. I’ll give it one more session and also shoot some different pellets next time — to see if I have been missing anything by shooting Crosman Premiers exclusively.
A hunter’s rifle
I have seen rifles like the NP2 before. They take some getting used to, but they reward the shooter with incredible accuracy once their secrets are learned. They’re rifles for hunters who use only a single rifle for all their needs. For the price this air rifle costs, I don’t think you can get one that’s any better.
Comparison with the first rifle
The first NP2 also took getting used to; but when I did, it gave me a best 25-yard group of 0.704 inches at 25 yards. So far, this rifle has given a best of 0.895 inches. Both rifles seem to want to do better, but I haven’t discovered quite how, just yet.

Here we go, again
Today, I’m starting our look at the second Benjamin Trail Nitro Piston 2. This rifle was sent from Crosman to Pyramyd Air especially for me to test, so we know that it’s the absolute best that they can do with the NP2 design. I’m not being sarcastic when I say that. I’m telling all the Crosman ankle-biters that I do acknowledge that this rifle has been thoroughly examined by Crosman before sending it to me — just to stop them from saying it. This is the same thing I recently did with the Daisy 880.
The first NP2 I tested came straight from the factory and was completely random. And you saw how well it turned out. You also saw that it needed a little time to break in before the cocking effort dropped to where we thought it should be. You also saw how I had to learn to hold the rifle for best accuracy. That shouldn’t happen with this one because I know how to hold it now.
I do plan on installing the scope that comes packed with the rifle for my test. We had one negative reader comment about me switching the scope on the other rifle, and doing it this way should end that complaint.
Out of the box
Several of you asked me to go over the second rifle thoroughly to see how it differs from the first rifle I tested. This rifle is also a .22-caliber model in a wood stock; so from the outside, it appears very much the same. But one curious thing I noted is that this rifle does have a wood screw holding the front of the triggerguard to the stock. You may remember I showed you the other rifle didn’t have the screw, even though the triggerguard has a hole for it.
I went over the entire rifle, looking for differences, but none came to light. I shined a tactical flashlight down the muzzle and noted that the baffles are not obstructing the muzzle. So, the rifle seems good to go.
I cocked it, just to see how that felt, and I was transported back to the SHOT Show! This rifle cocks with between 25-27 lbs. of effort. I found the barrel pivot joint was too loose for the barrel to remain in place after the rifle has been cocked. You normally want it to stay in one place, but I say that advisedly, because this NP2 might teach us a thing of two. Crosman designed this rifle with a pivot bolt instead of just a plain pin, so the pivot joint can be tightened whenever necessary. I took the action out of the stock to do this, and that’s when I noticed a number of things.
First, the barrel does indeed have a screw, but it was already tight on this gun. Then, I shined a flashlight through the action forks and the breech joint and noticed that there are probably bearings (what some would call shims) at the pivot joint. So, the barrel can be tight and yet still flop up and down after it’s cocked. We need to learn from this; because if this rifle is accurate, Crosman has done something new. Their barrel may be looser than other breakbarrels of the past and yet still be accurate.
Scope base welds
The welds on the scope base are much more visible on this second test rifle. I know that Crosman did take action on this issue right away after the first guns were launched.
Second, I found a u-shaped piece of steel on the floor after removing the stock. When I examined the stock, I found out what it is — pillar bedding! We’ve recently discussed this on this blog, and Crosman has apparently gone and done it. The interesting thing is that they didn’t mention it in their advertising! How could they have missed announcing an important feature like this? Shooters are paying hundreds of dollars to have their rifles pillar bedded, and Crosman has gone and done it for free and kept it a secret!
The 2 forward stock screw heads bear directly against the wood of the stock, so they’ll need washers to spread their load; but the NP2 is bedded better than 80 percent of the top-end spring rifles on the market.
Good to go
I assembled the rifle and found the barrel does not wobble side to side, yet it still flops after it’s cocked. This means the barrel pivot joint is adding very little resistance to the cocking effort. Now, it was time to start the velocity test.
The first pellet up was the 14.3-grain Crosman Premier that I believe will be one of the most accurate pellets for this rifle. Ten of them averaged 823 f.p.s. — a whopping 78 f.p.s. gain over the broken-in velocity of the first test rifle. And the cocking effort is still 5-7 lbs. lighter!
Best of all, Premiers varied by only 5 f.p.s. over the 10-shot spread — from 821 to 826 f.p.s. That’s phenomenal! It’s in PCP territory, and I’m talking about a regulated gun. At the average velocity, this pellet generates 21.51 foot-pounds of energy at the muzzle.
Next, I tried 21.1-grain Beeman Kodiaks. As powerful as this rifle is, it should handle them okay. They averaged 646 f.p.s., which means a muzzle energy of 19.46 foot-pounds. The spread for this heavyweight pellet was 12 f.p.s., ranging from 639 to 651 f.p.s.
You might wonder why I didn’t test the JSB Exact RS dome in this rifle since I did test it in the first rifle. The reason was the poor performance we saw in that first velocity test. I decided to switch to the Kodiaks rather than test a pellet that might not be suited to this powerplant.
The last pellet I tested was the 9.5-grain lead-free Crosman SSP pointed pellet. They averaged 1023 f.p.s. from the NP2, with a 55 f.p.s. spread that ranged from 992 f.p.s. to 1047 f.p.s. This is getting up close to the 1100 f.p.s. velocity that’s printed on the outside of the NP2 box. At the average velocity, this pellet generates 22.08 foot-pounds of energy.
The trigger on this new test rifle feels very similar to the one I tested on the first rifle. The first stage is long and heavy, measuring 3 lbs., 6 oz. to stage 2. Stage 2 was breaking at over 6 lbs. out of the box, but I adjusted it to 4 lbs., 4 oz., which is exactly the same as the first trigger. This is a very good trigger for a sporting airgun — especially considering the price!
Evaluation thus far
This is more like the rifle I shot back in January. I think anyone would be happy with this one; and if they aren’t, then they should reconsider getting a gas-spring air rifle altogether. I sure hope this rifle is at least as accurate as the first one turned out to be.

• What happens next?
You waited for this report. I told you it was going to be a good one. I even advised a couple people to just buy this rifle if they wanted a quiet and powerful PCP that was also accurate. Today, you’re going to see why I said that.
Best test ever conducted!
To cut to the chase, this was the best test of an air rifle I’ve ever conducted at 50 yards. I won’t go so far as to say that the Hatsan AT44S-10 Long QE is the most accurate air rifle I’ve ever fired, because you’ve seen in recent days that I seem somewhat variable. I refer to yesterday’s good test of the Air Arms Shamal after a pervious mediocre test.
However, if I can repeat today’s results at some future date, then I’ll conclude that this rifle is the most accurate air rifle I’ve ever tested at 50 yards. But I’m getting way ahead of myself. Let’s see what happened.
If you’re a regular blog reader, you already know that I was having a good day because the Shamal had just turned in several great groups — including one stunner that measured 0.818 inches for 10 shots at 50 yards. Now, it was the Hatsan’s turn on the bench, and the weather was still perfect.
Scope and mounts
I had mounted an AirForce 4-16X50 scope on the rifle using UTG 2-piece Max Strength high Weaver rings for a 1-inch scope. One of our readers heard that the Hatsan scope base that allows both Weaver and 11mm scope rings to be mounted has problems with Weaver rings, so he asked me specifically to use rings that have a Weaver dovetail on their base. I did, and the UTG mounts fit well, though I will say that the Hatsan base is at the wide end of acceptable width.
But I think I see what the reader has heard about, and I want to share it with you. There are some shooters who feel that all mounts must look attractive and squared away or they don’t fit right. What these people don’t understand is that mount makers use base jaws that will fit as many different configurations of dovetail cuts as possible — because gun manufacturers do not use many standards when making their cuts.
Scope base design
I’m going to explain something here, and I want you to try to understand it because it will make all the difference if you do. Weaver bases are a standard that specifies the width and height of the dovetail, and the width of the cross groove that accepts the locking bar on the mount. But the angle of the cuts that shape the dovetail grooves are not as certain. No doubt, Weaver specifies them, but mount makers don’t always conform to that spec. They use dovetail cutters with varying angles. To deal with this inconsistency, many mount makers, including Leapers, cut the jaws of their ring base clamps with rounded points, so they’ll grip most dovetails, regardless of the angle of the cut.
If there was only one rounded point on the clamp base, the ring would sit cockeyed on the rifle; but when the other end of the same clamp also has a rounded point that engages a special cut in the scope ring and the two cockeyed points cancel each other. The result is a scope ring clamp jaw that looks cockeyed, yet the ring sits squarely on the gun.
In the 1990s, B-Square owner Dan Bechtel and I did a project to determine the standard width of 11mm airgun dovetails. This is where we discovered that those dovetails vary between 9.5mm and almost 14mm in width. The angles of cuts ranged from 45 degrees to 60 degrees. The Weaver base is more standardized, but the cut angles still vary and have to be addressed.
Here you see how the rounded point of the scope ring clamp jaw allows it to fit into a wide variety of rifle dovetail base cuts. Having a rounded point on the other end of the same clamp will cancel this odd angle and allow the scope ring to sit squarely on the rifle.
The genius of this clamp design is lost on many people who see the cockeyed part as a flaw or mistake. Actually, it’s a compensating part that assures an exact fit on a variety of different gun bases. The picture shows this clearly.
For that reason, my answer to the reader who asked whether the Hatsan bases will accept a Weaver ring is — yes. Many ring manufacturers make their ring base jaws this way. If you can tolerate the odd appearance, this solution works perfectly.
On to the range
I was at the range on a perfect day, so this test would be conclusive if a good pellet was found. In the past, you’ve seen me work through a list of pellets, looking for the best one. Well, on this day I happened to find that pellet on the second try. At least, I think that’s the case because that pellet did so well that I didn’t bother trying any others.
I filled the rifle to the manufacturer’s recommended 200 bar (2900 psi) and loaded the 10-shot magazine. The first pellet I shot was the 14.3-grain Crosman Premier dome. I put 10 into 1.463 inches, but I’m not going to bother showing you that group because of what happened next. I knew from the velocity test we did in Part 2 that this rifle probably gets at least 20 good shots per fill when shooting at 50 yards. The velocity does decline with every shot; but as you’ll soon see, that doesn’t seem to matter much.
The second pellet I tried was the 16-grain Air Arms Diabolo Field pellet. It’s a dome that sits comfortably in the middle of the .22-caliber pellet weight range. Although it resembles the 15.9-grain JSB Exact Jumbo and although JSB does produce this pellet for Air Arms, they do so on proprietary dies owned by Air Arms; so, the two pellets are not the same and should not be confused with each other. On other tests, I’ve seen different results from these two pellets.
These 10 pellets were fired on the same fill as the Premiers, so the rifle’s internal pressure was down around 2500 psi when I started shooting. Every pellet went to the same place on the target. It was like they were being guided, or something. The result was 10 shots into a group that measures 0.681 inches between the two centers that are most distant. I was stunned when the group was finished! I’ve probably shot a couple other groups that small with airguns before — certainly with my Talon SS and probably also with a Benjamin Marauder — but this still ranks as one of the best groups I’ve ever shot at 50 yards with an air rifle. And the day was just beginning!
Following that, I refilled the rifle, for 20 shots had now been fired. The pressure had dropped to below 2000 psi, and I think to as low as 1750. I filled it back to 2900 psi and went back to the bench.
The next 10 shots were with the same Air Arms pellets, only this time we started at a full fill instead of only a partial. Ten pellets went into 0.992 inches this time — a little larger, but still in good territory.
Ten more Air Arms 16-grain domes made this 0.992-inch group at 50 yards when the rifle was filled to the maximum. This isn’t a screamer; but coming on the heels of the previous group, it’s pretty good!
Now the rifle was back down to where it had been for the first great group. So, I loaded 10 more Air Arms pellets into the rotary clip and settled down to shoot another group. This time, all 10 went into 0.624 inches. A definite screamer; and with the first group, pretty good proof that the Hatsan AT44-10 Long QE I’m testing is a shooter.
Ten more Air Arms domes made this 0.624-inch group at 50 yards when the rifle was fired on a partial fill. This is the best group of the session and also one of the best 50-yard 10-shot groups I’ve ever shot with an air rifle.
Airgunners…just like golfers!
Like a golfer who shot a sub-par game in which he also got a hole-in-one, I decided that my good luck had probably run its course this day. Besides the 40 shots fired with this rifle, I had also tested the Shamal and shot an additional 40 shots there because there were some adjustments to the scope that had to be made. In all, I’d shot 80 precision shots this day. That’s tiring.
What happens next?
I’ve never had an air rifle that would shoot this many consistently small groups in succession. Either I was having the best shooting day of my life, or this Hatsan rifle can really shoot. I want to return to the range under similar shooting conditions and see if I can repeat this. And I’ll continue to shoot the Air Arms pellets.
I just want to make sure this test was a valid one. It isn’t every day that you shoot the most accurate air rifle you’ve ever seen. I told several readers not to worry but to just buy the rifle if that was what they wanted. Now you see why.
After seeing what can be done with the Air Arms pellet, I want to explore some other pellets in this Hatsan. Hopefully, it’ll do well with several brands so there’s a choice.
After that, who knows? Maybe I’ll try this one at 100 yards. You may remember that I shot a one-inch group of 10 at 100 yards with a CondorSS last year. I wonder if this rifle can do as well?
