Welcome to the last report on the Beeman R10 that I tuned. This will be the accuracy test at 25 yards.

The test

I shot the rifle off a sandbag rest at 25 yards. I used an artillery hold with my off hand back by the triggerguard. I shot 5-shot groups to test more pellets and then 10-shot groups when I found a good one.


I scoped the rifle with a UTG Bug Buster 3-12X32 scope. It fit the R10 quite well, and when you see my groups I think you will agree that the scope worked.

R10 scoped
The Bug Buster fit the R10 well.

Sight in

I knew the scope was shimmed to take care of moderate barrel droop so I fired two shots at 12 feet and was immediately able to move back to 25 yards. Shots three and four were used to refine the zero and then I fired the first 5-shot group. read more

Ari Venturi M8
Air Venturi M8 is very much like the Bronco.

This report covers:

  • The assumptions

    Artillery hold
    Deep seated pellets
    Artillery hold
    The test
    Air Arms Falcons
    Directly on the sandbag

Today we begin looking at the accuracy of the Tech Force M8 pellet rifle — a breakbarrel that we have discovered is very similar to the discontinued Air Venturi Bronco. Because it is so similar, we can take what we already know about the Bronco and apply it to this rifle — the results will probably be the same, or similar, though we have to watch for anomalies that could crop up.

Today is accuracy day — the first of two such days we will have with the M8. Today I’m shooting the rifle at 10 meters. That gets me on the target and gives a chance for the rifle and scope to settle down.

The M8 comes without sights, so I have mounted a scope, and I think my selection will surprise you. I didn’t choose a whomptydoodle monster scope that costs three times as much as the rifle. Instead I’ve mounted a Gamo 3-9X40 scope with fixed parallax. This scope is nothing special — it probably came with a bundle deal on some other airgun. It’s reasonably clear and sharp, and size-wise it is well-matched to the M8. I shimmed the rear ring of the 1-piece Gamo scope mount that came with the scope, just to offset any possible barrel droop.

The assumptions

Now let’s look at the assumptions I made when starting this test. These are based on results when testing the Bronco.

Premier lites

When I looked back over the 11 blog reports I did on the Bronco, I found that Crosman Premier lites stood out as the most accurate pellet. The M8 has the same thin steel inner barrel inside a metal outer tube that the Bronco had, so there is no reason to suspect this is anything other than the same barrel.

Deep seated pellets

Another thing I discovered in researching for this test is that my Broncos like their pellets seated deep. I used the Air Venturi Pellet Seater that allows adjustment for the seating depth. I will start the test with deep seated pellets and only change if that doesn’t seem to hold true for the M8.

Artillery hold

I also discovered that the Bronco does not like being rested directly on a sandbag. In fact it liked a specific type of artillery hold that I talked about in Part 5 of the original Bronco report, back in 2010. So that is how I will begin testing the M8 — with Premier lites and with the special artillery hold.

The test

Well, the best-laid plans… A lot of my assumptions did not work out. First, I couldn’t get Premier lites to group no matter what I did. I tried deep seating, flush seating and 3 different hand placements of my off hand, but nothing worked well. The best group of 10 Premier lites I got at 10 meters out of 3 targets measured 0.929 inches between centers.

Ari Venturi M8 Premier lite group
This is the best of three 10-shot groups shot at 10 meters with Crosman Premier 7.9-grain pellets. It measures 0.929 inches between centers. I don’t think the M8 likes the Premier lite.

Air Arms Falcons

I then switched to Air Arms Falcon pellets and the groups tightened up. The first group of 10 was shot with a conventional artillery hold. That means the off hand was back on the stock touching the front of the triggerguard. Ten Falcon pellets seated deep went into 0.587 inches at 10 meters. Now, that’s a group!

Ari Venturi M8 Falcon group
This is the first 10-shot group shot at 10 meters with Air Arms Falcon pellets. It measures 0.587 inches between centers. This is what I was hoping for from the M8.

Then I slid my off hand out to the end of the stock. This makes the rifle very stable, but it also proved to be quite twitchy. Nine of the 10 deep-seated pellets went into 0.858-inches, but one shot that was actually shot number 5 in the string, went wide left — opening the group to a whopping 1.644 inches. That was due to a variation of the hold and I felt it before the trigger broke. I cannot recommend this hold for the M8.

Ari Venturi M8 Falcon group 2
This is the second 10-shot group shot at 10 meters with Air Arms Falcon pellets. It measures 1.644 inches between centers, though 9 shots are in 0.858 inches. What a huge difference the placement of the off hand made!

Directly on the sandbag

I finished the test by placing the rifle directly on the sandbag and seating the pellets flush with the breech — things the Bronco didn’t like one bit! But the Bronco was shooting Crosman Premier lites at the time I tried it, so it was worth a gamble to try the M8 rested this way.

Ten pellets went into 0.581 inches, which is very close to the size of the first group of Falcons. I think Falcon pellets are good in the M8 and I think you can either use a conventional artillery hold or rest the rifle directly on the sandbag.

Ari Venturi M8 Falcon group 3
This is the third 10-shot group shot at 10 meters with Air Arms Falcon pellets. The rifle was rested directly on a sandbag. The group measures 0.581 inches between centers, and is the smallest of the test, though it’s really too close to the first Falcon group to call. Falcon pellets perform very well in this rifle when it is rested right! read more

Benjamin Trail Nitro Piston 2
Benjamin Trail Nitro Piston 2

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.

The hold
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.

Benjamin Trail Nitro Piston 2 Artillery hold group
When I used the classic artillery hold, this is what I got at 25 yards — every time! They’re all in line but off vertically. The NP2 wants to be held firmly.

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.

The best 25-yard group using the factory scope and the best hold measures 1.104 inches between centers. No, I didn’t get the images mixed up. This group is slightly smaller than the one below.

The worst group with the factory scope isn’t much different than the best. Ten Premiers went into 1.168 inches at 25 yards. read more

Testing the effect of hold on an accurate spring-piston air rifle: Part 2

by Tom Gaylord, a.k.a. B.B. Pelletier

Testing the effect of hold on an accurate spring-piston air rifle: Part 1
Calling the shot and follow-through
Settling into a firing position

I thought this was going to be a one-time report. I would show how the hold affects the accuracy of a spring-piston rifle and that would be it. Well, the best-laid plans…

Blog reader Slinging Lead said he thought that lower-powered breakbarrels shoot just as accurately when rested directly on a bag as they do when shot with the artillery hold. I had to admit that the TX200 does shoot well off a bag, although that rifle is an underlever — not a breakbarrel. And it’s certainly not lower-powered. Then, blog reader BG_Farmer entered the conversation and requested this test.

While all this was transpiring, blog reader Kevin Lentz sent me 2 tins of Air Arms Falcon pellets to try in my R8. He said his R8 shot them slightly better than it shot the JSB Exact RS pellets that I normally use in my R8.

Now, we had a multivariate discussion going on! On one hand we wondered which pellets were the most accurate in my R8; and on the other hand, we wondered if the gun was as accurate when rested directly on the bag as it was when held with the artillery hold.

How do you test all that? Do you start by testing one of the 2 pellets, or do you first find the best hold? My approach in situations like this has always been to just start testing and let the methodology work itself out as I progress.

This time, I started by shooting the gun with both pellets. I shot them with the artillery hold the way I always had, then I rested the gun directly on the sandbag and shot both pellets again. The first day’s results were not very good, but they did illuminate something that helped me structure the second day’s shooting. It turns out that, although the R8 is a very accurate springer, it’s still ultra-sensitive to hold. I guess I’d forgotten that, but on the first day’s shooting it slapped me in the face. I found that even the slightest variation in hold would throw the pellet sideways with a vengeance, and that held true for both the Falcon pellets and the JSB Exact RS pellets.

Ten-shot groups are the way to go
Once again, I must sing the praises of 10-shot groups over 5-shot groups. When you shoot 10 shots, you allow the gun to do its thing; and that tells you what the real accuracy is. People say they don’t shoot 10 shots because something can go wrong — that it’s easy to hold the rifle steady for 5 shots, but close to impossible to hold it right 10 times in a row. I say that’s just a lie we tell ourselves because 5-shot groups look so much better. Yes, it’s hard to hold a gun correctly 10 times in a row; and yes, you’ll make mistakes. I make them all the time. But if you get into the habit of shooting 10-shot groups, you’ll also KNOW when you make those mistakes; and in time, you’ll make fewer of them.

The first results — JSB Exact RS pellets
The rest of this report will be mostly the photos of the groups. I’ll start with the JSB Exact RS pellets.

JSB Exact RS pellets handheld poor hold
On the first day, this is what my artillery hold did with 10 JSB RS pellets at 25 yards. Group measures 0.647 inches.

JSB Exact RS pellets handheld good hold
On the second day, my artillery hold was more precise shot-to-shot, and I got groups that were smaller and rounder. Here are 10 JSB RS pellets from the artillery hold at 25 yards. Group measures 0.503 inches.

JSB Exact RS pellets bag rested day 1
Resting directly on the bag on the first day produced a slightly smaller group than the handheld one. Ten JSB RS pellets rested on a bag went into 0.571 inches between centers at 25 yards.

JSB Exact RS pellets bag rested day 2
Resting directly on the bag on day 2 also beat the handheld group on that day.Ten JSB RS pellets rested on a bag went into 0.379 inches between centers at 25 yards. This is the smallest group of this test. read more

Testing the effect of hold on an accurate spring-piston air rifle

by Tom Gaylord, a.k.a. B.B. Pelletier

Calling the shot and follow-through
Settling into a firing position

Today’s report is one of those serendipitous events that happen when I think I’m investigating something simple and it turns out to be a treasure trove of shooting information. I thought today’s test was a demonstration of how settling into a firing position and following through would give a better group from an air rifle of proven accuracy. What I got was that and more!

I chose the .177-caliber Beeman R8 air rifle and JSB Exact RS pellet for this test because, in the past, this has proved to be a great combination. I shot 10-shot groups at 25 yards, which should show any differences if they really exist. Initially, I’d thought to shoot the rifle in a deer-hunter hold (meaning that I grasped the stock and pulled it firmly into my shoulder), an artillery hold without the tension being taken out of my hold (in other words, holding the rifle lightly, but held on target by muscle power and not by relaxing and adjusting the hold) and finally by settling in properly with an artillery hold. However, as I started this test, I thought that I’d also shoot the rifle directly off the sandbag to show how that affected the group size.

As I started the test, I realized that one group would have to be shot last, which would be at the time I was getting tired. I didn’t want to bias the results, so I put the neutral hold (the potentially best hold) at the end of the test.

Directly rested on sandbags
The first shot off the bag went through the center of the bull, and shot 2 went through the same hole. At that point, I thought this test was going to prove that I was wrong and that this gun really could be shot directly off a bag. Because of that, I knew that bias could creep in at this point. So, shot 3 was taken with the greatest care; yet, shot 3 went way to the right, and I knew the wisdom of not resting directly on sandbags was holding true.

KJSB Exactv RS pellet rested on sandbag
Ten JSB Exact RS pellets went onto 0.593 inches at 25 yards when the rifle was rested directly on the sandbag.

Deer hunter
This hold is one where you grasp the rifle tightly, pulling it into the shoulder the way a hunter might hold a powerful rifle. This was the most difficult hold to execute because the rifle was twitching around from the tight muscles. I didn’t have a death grip on it — just a firm hold; but through the scope, the movement was disconcerting.

JSB Exact RS pellet rifle held firmly
Ten JSB Exact RS pellets went onto 0.949 inches at 25 yards when the rifle was held firmly like a hunting rifle. The horizontal spread is due to tense muscles.

Artillery hold without settling-in
This hold just felt wrong with every shot because I knew I hadn’t settled in. Were I to relax before the shot while using this hold, the crosshairs would invariable move to the right. And see what kind of group I got? There’s one large hole surrounded by 4 wild shots. This is the kind of group that will drive a shooter nuts because it looks so good in general but still has those few wild shots. You wonder what’s wrong and want to blame the rifle, the barrel crown and the pellet. But in actuality, it all came down to the hold.

JSB Exact RS pellet artillery hold under tension
Ten JSB Exact RS pellets went onto 0.728 inches at 25 yards when the rifle was held using the artillery hold but not settling in. The wild shots are caused by tense muscles.

Now comes the big lesson!
Here is where the test turned around and taught me more than I anticipated. By the time I got to this point, I’d already fired 30 good shots without a single called flier. The dispersion you see on the targets above is entirely due to the holds that were used to create them. But taking 30 good shots is very tiring. And it showed on my next attempt to shoot a good 10-shot group.

What happened was I didn’t relax as completely as I should have. There was still a bit of tension in my muscles. Part of that is because my R8 has a Tyrolean stock whose high cupped cheekpiece is horrible for shooting off a bench rest because it forces you to put your cheek against the stock. But knowing that these shots were fired with a bit of tension in this case turned out to be a wonderful thing because I got 2 distinct groups!

JSB Exact RS pellet artillery hold with a little tension
Four JSB Exact RS pellets went onto 2 distinct groups at 25 yards when the rifle was held using the artillery hold, but I still didn’t settle in as completely as I should have. The “group” on the left looks like a single shot, but I know for a fact that it contains 2 pellets. The group on the right is very obviously two pellets. The distance between the centers of these 4 shots is 0.574 inches. read more

Settling into a firing position

by Tom Gaylord, a.k.a. B.B. Pelletier

Today was supposed to be Part 2 of the report on the BSA Scorpion 1200 SE, but I had an accident (actually a stupident) last night that prevented me from completing the test. I was slicing open a roll of bullet grease for my sizer/lubricator, and I slipped and cut my hand deeply. Today, as I was pumping the Hill pump to fill the rifle for the test, the wound reopened and I had to stop. Because the BSA fills to 232 bar and has a proprietary fill probe, I use the Hill pump because I don’t want to change out my more common Foster adapter on my carbon fiber tank since it fills most of the PCPs I own. Proprietary fill couplings are relegated to the hand pump.

This is also going to delay the next report of the Hatsan AT P1 pistol and the Evanix Rainstorm 3D bullpup rifle, as both of those PCPs also have proprietary fill probes and, of course, none of them fit any other gun — nor do they fit the BSA rifle! So, the only PCP I can report on for a week or 2 will be the Benjamin Marauder because it has a standard Foster fill coupling.

Today, I want to address the issue that blog reader Beazer brought up the other day when I talked about calling shots and following through. He mentioned that with his heavy-recoiling gas spring rifle, which he calls Mr. Nasty, he cannot keep the crosshairs on the point of aim after the shot fires. He wondered what to do about it. Let me pull a quote from his comment that explains everything well.

… should my sight picture return to p.o.a. after all the dust settles? Asked another way, if my reticle winds up off target, but my shot is close to on target, is something wrong in my shot execution?

Several other readers made similar comments about recoiling firearms. Obviously, this was a point that I failed to make in that report. Today, I want to set things right and talk about the ideal shooting position.

Let’s say I’m shooting at a 100-yard target with the open sights on a bolt action O3-A3 Springfield military rifle. This rifle is caliber .30-06, and it does recoil significantly. Nobody can hold the sights on the point of aim while this gun recoils. What I was trying to say in the report is that at the last instant before the shot fires, you look at your aim point reference for calling your shot. Someone else said it better — I think it was Fred. He says he takes a “mental snapshot” of the sight picture just before the gun fires. That’s a great way of saying what has to happen. No one can hold so still that they always know where the shot will go, but experienced shooters do watch their sights so they know where the gun is at the instant it fires. That tells them where the shot is going, and that’s how you call the shot.

So, on the O3-A3, I’m watching the front sight blade through the rear peep aperture, and I note the instant that the big service rifle fires. Of course, I lose all track of the target and sight picture after that. But if I saw where the front blade was at the moment of cartridge ignition, I know what I need to know to determine where the bullet probably went.

But what about what Beazer asked? Should the rifle return to the aim point after firing? In an ideal world, I guess it should, and maybe that’s possible for pellet rifles and rimfires more than it is for powerful centerfire firearms. The big kickers, like my .30-06, are going to push you around some, so don’t be surprised if you aren’t on target after the dust settles.

Instead of looking at it that way, I would like to turn things around and look from a different perspective. I would like to talk about how you settle in before you take the shot.

When I’m on a benchrest, or even when I’m in a seated or standing-supported firing position, it takes time for me to settle-in properly. I keep adjusting things until the rifle is aimed at the target when I’m completely relaxed. Don’t get confused — I don’t necessarily mean that I’m holding the rifle loosely. If the gun is a pellet rifle, I’m probably holding it loosely; but if I’m shooting a hard-recoiling rifle like a .30-06, you can be sure that I have the butt tight against my shoulder and the thumb of my firing hand is positioned to not break my nose when it comes back at me in recoil! Cowboy Star Dad told us that he’s learned to hold his .22 Magnum rifle firmly for best results, so maybe it’s only pellet rifles that are held loosely.

When I settle in the first concern is to rest the rifle as straight as possible toward the target. I’m now talking about looking through the sights and centering the rifle using them. If I’m using a rifle rest, that’s what gets moved from side to side. If I’m resting the rifle on my hands or directly on a sandbag, I put the butt to my shoulder and sight through the sights, then move the bag or my hands to center the rifle. If the rifle is handheld, my elbows also determine where it points; so once the gross corrections are made with the rest, I begin to make small adjustments of the elbows.

The object is that when I hold the rifle, the sights are aligned with the target so that when I close my eyes and relax, the sights remain aligned as before. I actually do this sometimes — close my eyes, take a deep breath and let it out, then open my eyes and see where the sights are. If they’re not aligned as I want them to be, I make adjustments to the hold and do it again. This works for rifles that are loosely held and for those that are held tightly.

I haven’t mentioned elevation yet, but of course that’s just as important as right and left. If I’m shooting off a rest that has a vertical adjustment capability, it gets adjusted up and down until the front sight is perfectly aligned. If the rifle is handheld, I do the same thing with my grip and the sandbag under it, if there is one.

One more thing
There’s one last step to this hold. That’s to touch the trigger and make sure the rifle doesn’t move away from the target as it’s squeezed. Sometimes this final step is the place where that last little bit of muscle tension gets revealed and corrected.

Do this for every shot
I know it sounds anal, but I repeat this process for every shot. You may think that a .223 Remington cartridge doesn’t recoil much; and in an AR-15 rifle, it certainly doesn’t — but even that pipsqueak cartridge moves the rifle enough to warrant this kind of attention, shot after shot.

If you’ll settle in like this for every shot, you’ll find that your groups grow smaller and smaller. You may already be using the artillery hold, but this procedure is part of it. I haven’t talked about this very much until now; but if you read my R1 book, you’ll see that I give today’s settling-in procedure the same importance as the artillery hold. This is what allows for calling the shot and for following through.

What about handguns?
Everything I’ve said today applies to rifles, only. Is there anything equivalent for handguns? You bet there is! There’s enough material to warrant at least one whole report of its own if there’s any interest among you readers. Today, I wanted to remain with rifles because there was so much to explain that I didn’t want any distractions.

A simple test to demonstrate the hold
I have an idea. What if I shoot 3 groups at 25 yards with the same accurate spring rifle? My Beeman R8 seems like a good candidate. From past tests, we know that JSB Exact RS pellets are a good choice for that rifle. One group will be shot using the classic artillery hold and the settling-in procedure I described today. A second group will be shot using the artillery hold without settling-in. I’ll use my muscles to hold the rifle on target, but I’ll use the artillery hold. Then, I’ll shoot a third group while holding the rifle like a deer rifle — gripping the forearm and pistol grip tightly and pulling the butt firmly into my shoulder. I promise to try to shoot my absolute best with each position. One 10-shot group should show a difference if I’m right about this. Boy, will I be embarrassed if I’m not!

Gamo Whisper Fusion IGT breakbarrel air rifle: Part 4

Part 3

Gamo Whisper Fusion IGT air rifle
Gamo Whisper Fusion IGT air rifle.

Today will be a very interesting report, in my opinion. The Gamo Whisper Fusion IGT air rifle I’m testing turns out to be a fascinating airgun in many ways. Let’s get right to the report.

Today we will look at accuracy at 25 yards with the scoped rifle. The first thing I had to do, therefore, was mount the scope. The rifle came with a scope installed in a one-piece scope mount. Its vertical scope stop pin was already correctly adjusted to fit the stop pin hole in the raised mount on top of the rifle’s spring tube. That is rare, in my experience. Normally, the scope will be installed correctly in the mount but has to be taken out of the mount to sufficiently adjust the height of the stop pin.

I’d used this mount for my report on shimming scope rings, so I did remove the scope from the rings after all. Following that report, I left in the one shim that was shown in the report. The mount Gamo included with the test rifle has four screws per cap and seems to be a good one. It’s a one-piece design that does limit the positioning of the scope, but I was able to locate it fine for my use.

The adjustable cheekpiece helped a lot. I had it adjusted up to almost the top position, and my eye lined up with the rear of the scope with no unnatural repositioning of my head.

Surprise No. 2 was the scope. I initially sight-in at 12 feet to get the shots safely on paper, and inexpensive scopes are usually very blurry this close to the target — even if they’re set on low power. This rifle comes with a very nice Gamo 3-9X40 scope that was quite clear on 3x at 12 feet. Back up to 25 yards and boost the power to 9x, and the glass remains very clear. It’s been a long time since I liked a scope that came bundled with a gun as much as this.

The Smooth Action Trigger (SAT)
Next, I must comment on Gamo’s new SAT. It’s a 2-stage unit that has a light first stage and a second stage that you can feel as you continue to pull. The trigger blade moves through stage 2 smoothly and breaks cleanly, but not with the sudden glass-rod crispness we talk about all the time. Instead, the feel is one of movement that is predictable and can be controlled. It isn’t bad — it’s just different from other triggers.

I reported in Part 2 that the trigger breaks at 3 lbs., 12 oz. That may sound high if you read about PCP triggers breaking at less than a pound, but it really isn’t that bad. The thing to do is experience it for yourself before you judge it. I find it to be manageable and not at all troublesome to the best accuracy.

Light weight
The light weight of the rifle, on the other hand, does present something of a problem. This rifle is so light that even when the off hand touches the triggerguard, the rifle still has neutral balance. It floats in your hand. That makes it difficult to hold on the target because the crosshairs want to dance around. The solution is a very light artillery hold that does benefit the rifle’s accuracy, and I’ll address that in a moment.

Normally, this is where I launch into the accuracy test and start making comments about the groups. This time, I have more to say, and it isn’t just about the groups — except how they helped my understand the rifle in a diagnostic way.

JSB Exact RS
The first pellet tested was the JSB Exact RS that did so well in the 10-meter accuracy test with open sights. I knew from that test that these pellets like to be seated flush with the breech for best results.

As I shot these pellets, I saw a strange phenomenon unfold. The first 3 shots were out of the bull at 5 o’clock. Then, I relaxed very consciously and allowed the rifle to float on my off hand. The next several shots went into the black. On shot 8, I didn’t relax like I should have, and I threw 1 more shot out of the bull at 5 o’clock with the first 3. How interesting!

It was so interesting, in fact, that I shot a 14-shot group, so that 10 of the shots could be fired with me being very relaxed. When you look at where they landed, you can see that the hold was all-important to where this rifle grouped.

Gamo Whisper Fusion IGT air rifle JSB Exact RS group 25 yards
This group is very large — measuring 2.574 inches between centers. But it was a learning experience for me because it demonstrated very clearly that the hold dictates where the pellets will land.

Now that I knew something about how the rifle performed, I figured I could do a lot better. And the very next group confirmed that.

H&N Barcuda Match
Next up were the H&N Baracuda Match pellets that shot second-best in the 10-meter accuracy test. Now that I knew how to hold the rifle, I expected to see a better group. And that’s exactly what happened.

I adjusted the scope after finishing the first group, moving it a few clicks to the left. The first Baracuda Match landed at 11 o’clock, just outside the bull. Shot No. 2 hit at 8 o’clock outside the bull. I was obviously holding the rifle too tight, so I made a conscious effort to hold it looser and shots 3 through 7 hit inside the black. Then, I tensed up again, sending shot No. 8 into the same hole as shot 2. The final 2 shots were fired with complete relaxation, and I had a respectable group inside the bull to the left of center.

This time, there were only 3 shots that missed the main group, and all of them were fired with some tension in the hold. When I relaxed, I was able to put 7 shots into 0.789 inches. I think this represents the true accuracy potential of the rifle. Total group measures 1.995 inches.

Altering the hold
Now that I understood the rifle better, I decided to move my open palm out farther so I could feel the cocking slot. Sometimes, resting the rifle this far forward is better. It certainly makes it more stable.

This time, however, there was no improvement. The group opened up, and I could see no way of controlling where the shots went. The total group measures 1.754 inches between centers, which is tighter than the previous group overall; but there’s no tighter group within this group that tells me the rifle wanted to do any better. Although this is a smaller group, I think the previous group that was shot with the off hand touching the triggerguard shows more promise. So, I went back to the other hold for the next group.

Ten shots went into a more scattered group at 25 yards when the rifle was rested out on the forearm.

Two pellets I didn’t try were RWS Superdomes and Gamo Raptor PBA. Both had done so poorly in the 10-meter test that I felt it wasn’t worth the time to try them again at 25 yards. That’s one of the benefits of 10-meter testing — it eliminates some pellets.

But I wanted to try at least one more pellet, so I selected 7.9-grain Crosman Premier domes, simply because they’re often very accurate in spring guns.

I now knew the best hold for the rifle, so all I had to do was hold it as loosely as possible and let the pellets do the rest. Nine of the 10 pellets went into a nice group measuring 0.845 inches between centers. It was the first shot that opened it up to 1.596 inches.

Ten Crosman Premier Lites went into 1.596 inches at 25 yards, but 9 of them made a 0.845-inch group. I think the smaller group is representative of the true accuracy of the rifle with this pellet. read more
