This report covers:

• Accuracy testing
• RWS Hobby pellets
• Trigger control
• Shot cycle
• Gamo Match pellets
• Gamo Raptor PBA pellets
• Air Arms Falcon pellets
• What’s the verdict?

Let’s look at the accuracy of the Gamo P900 IGT air pistol. Several of you have wondered if this is the air pistol you’ve been waiting for — today, we’ll see.

Accuracy testing
I shot the pistol off a rest at 10 meters. I rested my hands on a sandbag and held the pistol away from the bag with a two-hand hold. I used a 6 o’clock hold sight picture, which is more difficult to do with a bead fiberoptic front sight. But the target was brightly lit, and the firing point was in the dark; so, the fiberoptics did not illuminate, nor did the strange yellow rear sight blade cause any problems.

All pellets were deeply seated with the Air Venturi Pellet Pen and Seater. You may remember that we discovered this pistol likes them seated deeply during the velocity test.

RWS Hobby pellets
The first pellet I tried was the RWS Hobby wadcutter that did so well in the velocity test. The first pellet landed to the left of the bull at about 7 o’clock, so I stopped looking and just shot the rest. Alas, when I was finished, the 10 shots had scattered over 1.724 inches. It looked more like a shotgun pattern than a group. Obviously, Hobbys are not the right pellet for this pistol.

Ten RWS Hobbys went into this 1.724-inch group at 10 meters. Despite being shot from a rest, this is not a good pellet for the pistol.

Trigger control
I find the trigger easy to operate. Stage 2 breaks relatively crisply and doesn’t take that much effort. As I said in Part 2, it’s a fine trigger.

Shot cycle
The P900 has a smooth shot cycle that’s quick and almost without vibration. It also doesn’t make much noise when it discharges. It just sits in your hand and pulses quietly with each shot. I know it has a gas spring, but it doesn’t have any of the usual drawbacks (hard cocking, stiff jolt upon firing, loud crack upon discharge, etc.) that I can see.

Gamo Match pellets
Next up were 10 Gamo Match wadcutters. Since this is a Gamo gun, I figured…why not? These pellets landed more in the center of the bull and also held a tighter group that measures 1.167 inches between centers. This is about what I expected the P900 to do.

Ten Gamo Match wadcutters went into this 1.167-inch group at 10 meters. This is more like it.

Gamo Raptor PBA pellets
Because I tried them in the velocity test, I figured I had to also try the Gamo Raptor PBA pellets for accuracy. I didn’t expect much, because I have seen Raptors do well only in one pistol so far — a smoothbore Marksman 1010. For some reason, they were better than any other pellet in that pistol when I tested it. But in the P900, they went into a group measuring 1.946 inches — the largest of this test.

Ten Gamo Raptor PBA pellets made this 1.946-inch group at 10 meters. This is the largest group of the test.

Air Arms Falcon
I thought I would give one more pellet a chance, so I tried the Air Arms Falcon dome. It’s light, at 7.3 grains, and it’s often among the most accurate pellets for a given gun. This time, they made the second-best 10-shot group, at 1.256 inches between centers. While that’s larger than I’d like to see, the pellets are nicely centered on the bull.

Gamo P900 IGT air pistol Falcon group

Ten Air Arms Falcon pellets went into this 1.256-inch group at 10 meters. It’s the second best group of the test and also nicely centered on the bull.

Of course, there’s no way to know if I’ve found the best pellets for the pistol without testing a lot of other brands. An owner would do that, of course.

What’s the verdict?
The P900 is a pleasant air pistol. It’s lightweight, holds well and has a nice trigger. The odd sights are easy to use, too. Take my results as typical; and if they satisfy you, this is a nice air pistol.

This report covers:

• Velocity
• RWS Hobby pellets
• Gamo Match pellets
• Gamo Raptor PBA pellets
• Trigger

Velocity
Let’s get right into the report. Today, we’ll look at the velocity of this Gamo P900 IGT air pistol. A number of comments were made about how underpowered this air pistol is, but I disagree. They’re condemning it without testing it — from just reading the numbers. We’ll set that straight today.

RWS Hobby pellets
The first pellet I tested was the 7-grain RWS Hobby wadcutter. This pure lead pellet is probably just right for the P900 powerplant. Gamo advertises the P900 as getting 400 f.p.s. with lead-free alloy pellets, so we expect the Hobbys to be slower because they’re heavier. And slower they are! When I seated them flush with the breech, Hobbys averaged 332 f.p.s. with a range from 321 to 340 — a spread of 19 f.p.s. They developed 1.71 foot-pounds, on average.

Because this pistol is lower powered, I decided to see what effect deep-seating the pellet would have. I used the Air Venturi Pellet Pen and Seater to seat the Hobby pellets deep in the breech. This time, the pellet averaged 365 f.p.s. — a gain of 38 f.p.s. The low velocity was 358 and the high was 373, so the spread was 15 f.p.s. Seated this way, they developed 2.07 foot-pounds, on average. I think it’s clear this pistol likes the pellets to be seated deep, so that’s how I will proceed with the test.

Gamo Match pellets
The next pellet I tested was the 7.56-grain Gamo Match wadcutter. I didn’t even try them seated flush. Seated deep, they averaged 360 f.p.s. with a spread from 358 to 363 f.p.s., so this time just 5 f.p.s. separated the slowest from the fastest pellet. At the average velocity, this pellet generated 2.18 foot-pounds of energy at the muzzle.

Gamo Raptor PBA pellets
The last pellet I tested was the Gamo Raptor PBA. This lead-free domed pellet weighs just 5.4 grains and is used to extract high velocity from airguns. Remember — Gamo advertises the P900 as getting up to 400 f.p.s. Well, that turns out to be quite conservative! This pistol I’m testing averaged 490 f.p.s. The range was from a low of 457 f.p.s. to a high of 508 f.p.s. So the spread was 51 f.p.s. At the average velocity this pellet generates 2.88 foot-pounds of muzzle energy.

Just to see what the differences are, I also shot 4 Raptor pellets loaded flush with the breech. They ranged from a low of 439 f.p.s. to a high of 455 f.p.s.; so even loaded normally, this pistol still exceeds its advertised velocity. I may have an example that’s on the hot side, and maybe you won’t get quite as much velocity as you see here, but I think they should all get at least 400 when shooting PBA pellets.

You naysayers can revise your arguments, now. This pistol exceeds its advertised expectations by a lot. I still like the firing behavior and the trigger, though I’m sure there will be critics.

Trigger
The non-adjustable 2-stage trigger on the test pistol breaks crisply at 3 lbs., 15 oz. to 4 lbs., 1 oz. It’s a fine trigger and just what I need to shoot this pistol accurately.

2014 Ft. Worth airgun show update
This report was short, so I’ll use the space to update you on the 2014 Ft. Worth airgun show that will be held on Saturday, September 6.

The following dealers and manufacturers are expected to have tables:

Pyramyd Air
Umarex USA
AirForce Airguns
Dennis Quackenbush
Flying Dragon Air Rifles (Mike Melick)
Hatsan USA

The following dealers and manufacturers are considering attending or have indicated they may attend:

Airgun Depot
Daisy
Crosman
Scott Pilkington
Neal Stepp

Also attending will be:

American Airgunner TV
Steve Criner — TV’s Dog Soldier
Eric Henderson — big bore airgun hunter and guide
Jim Chapman — writer for Predator Extreme magazine and airgun hunter

I’m making a big push to get the smaller private dealers now. These are the guys who have vintage airguns for sale. The club has a communal table for members to display and sell their airguns. This club is where I recently purchased the BSA Airsporter Stutzen I’ve been reporting on, a BSA Scorpion pistol and a Schimel gas pistol from the 1950s.

I am going to really shake the trees, because I know there are many airgunners who will come to this one-day show. The sheer volume of people though the door will make it worth their while to attend. Who knows what unusual airguns are going to walk through the doors?

If you have some unusual airguns to sell, this show is the place to sell them! We should get a number of advanced collectors who are attracted to this brand new airgun show because of the curious guns they may find. We’re also attracting those who are new to airguning and are looking for the vintage guns they’ve read about but never seen.

Don’t forget our door prize and the three major raffle prizes that have been donated:

Air Venturi Bronco
AirForce Condor SS
Hatsan AT44-10 Long QE
Walther LGV Master Ultra

Other drawings and freebies are also in the works. Lots of guns, lots of freebies, lots of fun!

Mark September 6 on your calendar. You’ll want to be at the Ft. Worth airgun show in Poolville, Texas.

Gamo P-25 air pistol: Part 3

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

Part 1
Part 2

Gamo P-25 air pistol
Gamo P-25 is a 16-shot blowback pellet pistol.

Today is accuracy day with the Gamo P-25 air pistol. I inserted a fresh CO2 cartridge into the gun, loaded both of its 8-shot rotary clips and then slid the magazine into the grip.

I shot the pistol at 10 meters, which seems appropriate for a gun of this type. I shot it rested with a two-hand hold and my arms resting on the sandbag but the pistol free to move.

The pistol has open sights that are not adjustable. They have white dots, both front and rear, but that was cancelled by lighting the target brightly and shooting from a dimly lit place. I used a 6 o’clock hold, and the sights were very sharp and easy to align.

Because each rotary clip holds 8 pellets, I shot 8-shot groups instead of the usual 10. I don’t think it makes a big difference; and when you see the targets, I think you’ll agree.

The P-25 has blowback, so every shot except the first is single-action. I therefore cocked the hammer for that first shot, so all shots were single-action. It’s the most accurate way to shoot any handgun.

RWS Hobby pellets
The first pellets I shot were RWS Hobbys. Because they’re wadcutters, they left good holes in the target paper that were visible from the firing line. The pistol shot Hobbys to the left, as you can see, but the elevation was pretty good. The pistol’s sights are not adjustable, so to move the shots means you have to either aim off or use some Kentucky windage.

The group isn’t very impressive — 8 shots in 2.169 inches at 10 meters. Perhaps one of the other pellets will do better.

Eight RWS Hobby pellets went into 2.169 inches at 10 meters.

Gamo Match pellets
The next 8 pellets I shot were Gamo Match wadcutters. These pellets will sometimes be very accurate in a particular gun, but the P-25 I’m testing isn’t one of them. Eight shots went into 2.894 inches, though 7 of them are in 1.846 inches. Still, neither group size is especially good. They did go to approximately the same point of impact as the RWS Hobbys, however.

Eight Gamo Match pellets went into 2.894 inches at 10 meters.

Crosman Premier lites
Next, it was time to try some 7.9-grain Crosman Premier lites. These domed pellets are sometimes the very best in certain airguns. And this was one of those times. Eight of them went into 1.624 inches, though they also went way over to the left.

Eight Crosman Premier lites went into 1.624 inches at 10 meters. This was the best group of this test.

Gamo Raptor PBA
The last pellet I tried was the lead-free Gamo Raptor PBA. We know from the velocity test that these pellets go the fastest in the P-25, but now we’ll see how accurate they are.

And the answer is — not very. Eight PBA pellets made a shotgun-like pattern that measures 4.036 inches between centers. Interestingly, they did tend to group in the center of the target — the only pellet of the 4 tested to do so.

Gamo P-25 air pistol target with Gamo Raptor pellets
Eight Gamo Raptor PBAs went all over the place, making this 4.036-inch group. I had to reduce the size of the photo to get all the holes into it.

Shooting behavior
This was one time I found myself hoping for greater accuracy from the test gun because it was so much fun to shoot. The blowback action is quick, crisp and comes as close to the recoil of a .22 rimfire pistol as I think I’ve experienced in an air pistol. Although the trigger is long and full of stops and starts, it’s also light and can become predictable after you learn its quirks.

Bottom line
The lack of adjustable sights means you have to find a pellet that shoots to center and is also accurate. Good luck with that. If Premier lites had shot to the center, they would have made this test end on a higher note. Because it shoots lead pellets from a rifled barrel, I’d hoped for better accuracy than this. Had I seen it, I would have rated this Gamo P-25 a best buy.

The benefits of oiling pellets: Part 2

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

Part 1

Let’s begin testing the effects of oiling pellets. There are numerous ways to approach this issue, and I have to pick one at a time and limit the test to just that. But I think as long as I’m testing one aspect, I ought to test it thoroughly so someone can’t come back and second-guess me later in the report.

So, today I’ll test with one rifle, and the next time I’ll test with another. What I won’t do is test with each different brand of airgun, just to see what will happen. If a powerful gas spring rifle performs in a certain way, I’ll assume that all powerful gas spring rifles are going to do the same. If the difference between dry pellets and oiled pellets is close, I may do additional testing; but if there’s clear separation, I’ll accept that as the way it works.

What am I testing?
The question that started this experiment was, “How much faster will oiled pellets shoot than those that are not oiled?” One reader has asked me to also test this downrange because he wonders if a thin coat of oil changes the laminar flow of air around a pellet. I may get to that at some point, but for the present I’m just concerned with muzzle velocity because all pellets slow down after they exit the muzzle — oiled or not.

I suppose this needs to be tested in all three powerplant types, but today I’m testing it in a spring-piston powerplant. Today’s gun is a weak powerplant, so next time I’ll test it in a more powerful gun.

I’m using an HW55 SF target rifle to test three pellets. This rifle is a variation of the old HW50 rifle, so it shoots in the 600-650 f.p.s. region with lead pellets.

Since oiled pellets will leave a film in the bore, I tested all pellets dry first, and then tested the oiled pellets afterwards. Before the first test shot with oiled pellets, I fired two pellets to condition the bore. That turned out not to be enough, but I’ll come to that later.

Pellet shapes
I’ll test the three major pellet shapes in this test. They’re the wadcutter, dome and pointed head. There are other shapes, like hollowpoints, but they’re based on one of these three main shapes, so this is all I’m testing.

How I oil pellets
I oil pellets in the following manner. A foam liner is placed in the bottom of a pellet tin, and 20 drops of Whiscombe Honey are dropped onto the foam. Then, a single layer of pellets is spread on the foam, and the tin is rolled around. I shake the tin lightly to move the pellets around…but not enough to damage them. Whatever oil transfers to the pellet is all the oil it gets. I’ve been doing this for many years and it works well.

Oiling pellets
Twenty drops of oil on the foam is what I use. Then, a single layer of pellets.

Oiling pellets tins
One tin for each type of pellet used in the test.

The pellets end up with a very light and uniform coat of oil. When I handle them the tips of my fingers become oily, but I can’t see any oil on the pellets. Other people use more oil than I do, but this is what I am testing.

Whiscombe Honey is a mixture of two-thirds Hoppes Gun Oil (not Number 9 bore cleaner!) and one-third STP Engine Treatment, by volume. Shake the mixture until is takes on a light yellow color. It will look like thin honey, hence the name. This mixture should not detonate easily in a spring gun.

Test one — dry pellets

Crosman Premiers
Crosman Premier 7.9-grain pellets were the domes I tested. The average velocity for dry Premiers was 606 f.p.s., with a low of 577 and a high of 616. So, the spread was 39 f.p.s. The average muzzle energy was 6.44 foot-pounds.

Gamo Match
For wadcutters, I tested Gamo Match pellets. The average for dry pellets was 652 f.p.s., with a low of 640 and a high of 663 f.p.s. The spread was 17 f.p.s. The average energy was 7.14 foot-pounds.

H&N Neue Spitzkugel
The pointed pellet I selected was the H&N Neue Spitzgugel. When shot dry, they averaged 601 f.p.s., with a low of 585 and a high of 620 f.p.s. The spread was 34 f.p.s. The average muzzle energy was 6.81 foot-pounds at the muzzle.

Oiled pellets
Now, I shot two oiled pellets through the bore to condition it and began the test.

Oiled Crosman Premiers
Oiled 7.9-grain Premiers averaged 591 f.p.s., but the spread went from a low of 545 to a high of 612 f.p.s. That’s a spread of 67 .p.s. The average energy for oiled pellets was 6.13 foot-pounds. I did notice the pellets were going faster at the end of the shot string, so I thought I might come back to them after testing the other pellets.

Oiled Gamo Match pellets
The oiled wadcutters averaged 658 f.p.s. — a slight gain over the dry pellets. But the real news was the spread, which went from a low of 651 to a high of 663 f.p.s. Instead of a 17 f.p.s. for the dry pellets, the oiled pellets gave a spread of just 12 f.p.s. That’s too close to draw any conclusions, but it’s interesting. The average energy with the oiled pellets was 7.27 foot-pounds. So, with the oiled pellets, the velocity went up — along with the energy — and the shot-to-shot variance went down.

Oiled H&N Neue Spitzkugel
Oiled Spitzkugels averaged 609 f.p.s. — which was a small increase over the same pellet when dry. The average energy was 6.99 foot-pounds. The spread went from 585 to 620 f.p.s, which was identical for the same pellet dry. Velocity and energy were both up slightly from dry pellets, and the shot-to-shot variance remained the same.

By now, it’s obvious that the bore needed more than two shots to condition it, so I retested the oiled Crosman Premiers. The second time the oiled pellets averaged 604 f.p.s., which is just 2 f.p.s. slower than the same pellets dry. But the spread that was 67 f.p.s. on the first test of oiled pellets and 39 f.p.s. with dry Premiers now went from a low of 594 to a high of 613 f.p.s. — a much tighter 19 f.p.s. total. The average energy was 6.40 foot-pounds.

Observations
From this test, I observed that these three pellets either remained at the same velocity or increased very slightly from the light oiling I gave them. In two of the three cases, the velocity spread got tighter when the pellets were oiled.

I further observed that it’s necessary to condition a bore with oiled pellets before doing any testing. As a minimum, I would say that 20 oiled pellets should be fired before testing.

These are very small differences from oiling; and although I can’t draw any conclusions yet, I would think that such a small change is not enough to matter. It hardly seems worth doing at this point. However, there’s still a test to be done in a powerful airgun. Until we see those results, I think it’s too soon to say anything for sure.

Although the question that drove this test was how much faster oiling pellets makes them shoot, I think we still have to take accuracy into account before forming any opinions.

Ruger Mark I pellet pistol: Part 3

by B.B. Pelletier

Part 1
Part 2


The Ruger Mark I pellet pistol is a powerful spring-piston gun.

Before I begin, here’s a followup to yesterday’s blog on the importance of stock length. I discovered, thanks to blog reader Mike, that the No. 4 SMLE has both a long and a short stock. Apparently, when there are complaints that the rifle kicks, the stock is always a short one. I tested that at the range yesterday with a friend of mine. He had a hard-kicking Mark III and, sure enough, it has a short stock. But my No. 4 stock is at least .75 inches longer and feels like a mild 30/30 when shot.

Okay, on to today’s blog.

There’s a lot of interest in this pellet pistol, and I’ve learned a lot more while testing it. Before I did this report I read as many reviews of this Ruger Mark I pellet pistol as I could find — both on this site and on others. I discovered something while doing that. There’s a sharp difference of opinion about the gun that divides around the age and airgun experience of the person writing the review. Those who are either young or have little experience with airguns say the Ruger is hard to cock and not very accurate, but they all praise the power they think it has. But veteran airgunners who own chronographs have learned that the pistol isn’t as powerful as advertised, but it’s easy to cock (very easy for the power, if you use the cocking aid) and also relatively accurate. So, come with me today while I show you what the Ruger can do.

I shot the gun for accuracy at 10 meters, because most of the reviews I read talked about shooting at distances from 25 feet to 10 meters. In the end, 10 meters turned out to be exactly the right distance for the gun.

I shot off a bag rest with both hands holding the pistol out just past the bag, so there was no contact between the bag and the gun. My forearms were resting on the bag. The sights are fiberoptic; but when held at arm’s length, the front sight just fills the rear notch perfectly. It’s possible to get a precise sight picture that can be repeated with every shot.

Trigger and cocking effort
The trigger-pull is very heavy — to the point of being a distraction. Blog reader Victor asked me to report on the trigger-pull and cocking effort after this test; I guess because he wanted to see if there was any change during break-in. After this accuracy test was completed, the gun had a total of about 140 shots on it. The trigger-pull measured 5 lbs., 13 oz., and the cocking effort with the aid installed is 26 lbs. That’s a pound higher for cocking, and the trigger is a half-pound heavier than the last time I checked. Both numbers are probably just due to how they were measured and no real change has occurred.

Accuracy
The nice thing about testing a gun with open sights is that it’s usually on the paper right out of the box, where a scope can be almost anywhere. This pistol was shooting high and left, but it was on the paper at 10 meters. It took a little elevation reduction and a lot of right adjustment to get the pellet to land in the bull. I sighted-in with RWS Hobbys. Then, I shot the first group of 10.

The first group surprised me, but that was when I realized that many of the reviews had been written by new shooters. I say that because the Ruger Mark I is an accurate air pistol when you use the correct holding technique. You hold the pistol firmly but do not try to prevent it from bouncing around in recoil. It’s not as accurate as a Beeman P1 or an RWS LP8, but it’s accurate, nonetheless. But only the experienced pistol shooters will know how to get this pistol to perform its best.

Ten RWS Hobbys grouped in a 1.073-inch group at 10 meters for me. The group is open but also nice and round. It was a lot better than I’d expected.


Ten RWS Hobby pellets made this nice round 1.073-inch group at 10 meters.

Following the Hobbys, I was in the right frame of mind for all further shooting. Next up was the JSB Exact RS domed pellet. We know from past experience that this pellet often does well in lower-powered springers, though I don’t think I’ve tried it in a pistol before now.

This time, the RS pellet did very well, indeed. In fact, it was the most accurate pellet of the three I tested. Ten made a group measuring 1.059 inches between centers. Though this group isn’t much smaller than the Hobby group, the smaller holes made by the domes make it appear smaller.


Ten JSB Exact RS domes made the best group of the test. It measures 1.059 inches between centers.

The last pellet I tried was the Gamo Match wadcutter. Sometimes, they surprise me by being the very best pellets in a gun, but this wasn’t one of those times. Ten pellets grouped in 1.595 inches between centers — hardly in the running with the first two pellets.


It only looks like nine holes because two pellets went through the same hole next to the number 7 at the bottom of the bull. Gamo Match pellets were not in the running, with this 1.595-inch group.

At this point in the test, my trigger finger was hurting from the weight of the pull, and I was concerned that further shooting would be affected by it. So, I ended the test. It sounds like it shouldn’t have hurt, but the pull is so long that it really does hurt.

The bottom line
If you want a powerful spring pistol at a budget price, I don’t think you can do any better than the Ruger Mark I. It demands good shooting technique and rewards it with decent accuracy. The power is respectable, and the cocking effort is low for the power generated. The trigger is heavy and the sights aren’t perfect, but they do adjust and the pistol does respond to them very well.

Most shooters will like the shape of the grip, which is reminiscent of the Luger. The Ruger Mark I is just about right in the weight and balance department and encourages plinking with its surprising accuracy.

New-old-stock TS-45 air rifles: Part 3

by B.B. Pelletier

Part 1
Part 2


This TS-45 rifle is probably at least 30 years old, yet also brand new.

I’ve anticipated this day with great hopes, because this TS-45 rifle has the tightest bore I’ve ever seen on a vintage Chinese air rifle. I’ve owned a couple older Chinese air rifles, and they always had huge bores that every pellet wallowed in. The only one that was ever accurate was another TS-45 that I modified by changing the barrel for a Lothar Walther from Dennis Quackenbush. That one also had the benefit of an overhaul and was really a nice little plinker after all the work was done. But it didn’t have the original oversized barrel.

Through the years, I’ve heard from many owners of Chinese springers who said they had accurate guns. And always their barrels were considerably tighter than any I’d seen. Well, Lady Luck finally smiled on me, because this time it was my turn to get a tight barrel. So, I anticipated the possibility of accuracy.

Loose stock screws
Before testing I tried to tighten the stock screws. The rear triggerguard screw and the rear sling swivel anchor screw are what hold the action in the stock. Both were loose and needed tightening.

For fun, I removed the barreled action from the stock. From what I see, this would be an easy action to work on, so I may have a go at it at some future date. No promises, but if I can collect another dozen “round tuits,” I’ll have what I need to smooth out this action.

Firing behavior
I have to compare the firing of this rifle to that of the El Gamo 68 I recently tested. Both have heavy triggers and quick shot cycles with very little vibration afterward. The firing pulse is heavy and disagreeable, but I think that with the fitting of a few parts it could be made smoother.

The trigger looks simple enough and is obviously has a case-hardened sear. I can tell that by the shape of the part and its thickness. If I were to rebuild the gun, I might have a go at smoothing the sear contact area a little.

Accuracy
I had a gut feeling this rifle wanted to shoot, and it didn’t disappoint me. The first pellet I tried was a 7.9-grain Crosman Premier dome. I shot at a 10-meter pistol target at a distance of 10 meters (33 feet). The pistol target has a larger bull than the 10-meter rifle target, and I find it easier to see when I use open sights like the ones on this rifle.


Ten Crosman Premier lites made this 1.657-inch group at 10 meters. Nine went into 0.891 inches. This is a very horizontal group.

Speaking of the sights, I find the sights on this TS-45 to be among the sharpest and easiest open sights I’ve ever seen on an air rifle! I wish the makers of modern air rifles would put sights this good on their guns! The rear sight has a U-shaped notch that’s positioned at just the right distance from my sighting eye, so the top of the notch appears clear. And the front post is very sharp and easy to focus on. I had no trouble holding a 6 o’clock hold on the target.

Trigger
The trigger, on the other hand, is appalling! It’s too heavy to measure on my trigger-pull scale, but I am guessing that it breaks at something approaching 14-15 lbs. of effort! It’s so heavy that my wrist started hurting from pulling it during the test. I’m not sure the final group I shot was as good as it could have been because my wrist hurt so much from squeezing this horrible trigger.

The first group wasn’t as nice as I had hoped, spreading out to the left as the shots increased, but it was much better than a typical old Chinese airgun would do for me. One pellet went way out to the left; but as far as I could tell, the sight picture was perfect for that shot, as well as for all the others. I used an artillery hold with the back of my off hand touching the front of the triggerguard. The rifle sits well in the hand for this hold and is light enough to feel good. Later in the series, I flipped my off hand over and rested the rifle on the backs of two fingers. That seemed to have less movement on target as the trigger was pulled.

The second pellet I tried was the RWS Hobby. I’ll usually default to this pellet in a lower-powered spring gun because, for some reason, many of them seem to like it very much. This pellet fit the bore very tight and gave the best group of the day.


RWS Hobbys made the best group of the test. Ten went into this group measuring 0.835 inches between centers.

The Hobby group was very encouraging. I started believing this rifle was going to shoot like a target rifle. The next pellet was shot with the Gamo Match, and here’s where I started to notice the heavy trigger-pull taking its toll. I can’t say for certain, but I think some of the size of this group was due to fatigue.


Ten Gamo Match pellets made this 0.845-inch group. Almost as small as the Hobby group, this one may have suffered from the fatigue of my trigger finger.

The final pellet I tested was the H&N Finale Match Pistol, but by this time there was no mistaking my fatigue. The only other time I remember feeling like this while shooting a gun was when I tested one of those $2,500 Airrow airguns made by Swivel Machine Corp. They had a trigger pull over 25 lbs. and were horrible to shoot. You can see the results of my fatigue in the vertically scattered shots, where the other three groups were good in the vertical plane.


This vertical dispersion is definitely due to the fatigue caused by the heavy trigger. Ten H&N Finale Match Pistol pellets made this 1.376-inch group at 10 meters.

What now?
As I indicated earlier, I’ll set this rifle aside for now. But it looks like a simple action to work on, and I may eventually return, just to see what I can do about that heavy trigger and violent pulse at firing.

I was never one to praise these old Chinese airguns; but if I’d encountered one like this one back in the days when I tested them, things might have turned out differently. I certainly would have cut them more slack if I’d known they could shoot so well.

Crosman MAR177 test report: Part 6

Crosman’s new MAR177 upper is big news!

Today’s test is shooting the Crosman MAR177 at 25 yards, both with and without the magazine. We’ll also shoot it with the best wadcutter target pellets and the best domed pellets to see what differences there are.

Rather than shoot the rifle myself, I let Mac shoot it this time. He is the better rifle shot between us, and I just wanted to see what the rifle would be like in his hands. He shot it off a bag rest at 25 yards indoors. Ten pellets were shot from the magazine, then another 10 of the same pellet were shot using the single-shot tray. Mac tested both domed and wadcutter pellets, so we get to compare the relative accuracy of both today. And the results did not turn out as I expected.

Magazine
I’d noted in an earlier report that the particular 10-shot magazine I’ve been using has two chambers with tight entrances. Mac found the same thing without being prompted by me. I had him use the same magazine as I did so I could compare his results with all other variables remaining the same.

You’ll recall that I mentioned not liking magazine guns because of how they handle the pellets. So, today was also a test between the magazine and loading each pellet as you shoot. I’m not saying that all pellets have feeding problems, but that some magazines may have a problem. But when you load each pellet singly, you have less chance of damaging the pellet.

Single-load tray
That said, the MAR177 has a gap at the front of the single-load tray that can catch the nose of certain pellets and make it very difficult to load. The H&N Field Target pellets that were the most accurate in an earlier test had this problem and had to be exchanged for a different domed pellet. The H&Ns have a semi-wadcutter rim around the head that just catches in the gap on the tray and causes the pellets to flip up and possibly get damaged on loading. I substituted 7.3-grain Air Arms Falcon pellets that fed perfectly through the tray.

On to the shooting
Let’s get right to today’s test. First, Mac tested the domed pellets at 25 yards.


Through the 10-shot magazine, 10 Falcon pellets made this 0.667-inch group at 25 yards. This is very good!


When the single-shot tray was used, 10 Falcon pellets made this 0.429-inch group at 25 yards. This is clearly better than the group made using magazine-fed pellets.

Mac tried the H&N Field Target pellets first, and they were very accurate, but a couple of them refused to feed through the magazine. But the Falcon pellets fed flawlessly, so we changed the test to use them as the domed pellet of choice. Once again, I want to say that in another magazine this pellet might have fed better, but this is a quirk you get with mags that you don’t get when loading singly.

Clearly the single-loaded pellets are more accurate than those loaded by the magazine. That may not hold from magazine to magazine; but for this one mag, you’re better off loading the pellets one at a time. Let’s see how the rifle does with wadcutters at 25 yards.


Using the magazine, 10 RWS R10 7.7-grain pellets (an obsolete weight for the R10) grouped in 0.484 inches at 25 yards. That’s great performance.


When each pellet was loaded singly, the R10s grouped 10 in 0.402 inches. This was the best group of the test!

The trend continued with the wadcutter pellets. The R10s grouped even tighter than the Falcons at 25 yards, and those that were loaded singly did much better than those that fed through the magazine.

What have we learned?
First, we’ve learned that some magazines do influence the accuracy of the gun with all ammunition — or at least with the pellet types used in this test. A different magazine might well give different results, but one thing it will never do is outshoot loading the pellets by hand, one at a time. As a 10-meter shooter, I knew this going into the test. But it was nice that we were able to demonstrate it so clearly.

Next, we see that wadcutters were more accurate than the domes in this test. Even though both pellets were very accurate, the wadcutters had the edge. That was the part that surprised me. I’d expected the domes to take over at 25 yards.

The bottom line
The Crosman MAR177 is a valuable addition to an AR and a wonderful target rifle in its own right. It was held back in this test by the use of an AR National Match trigger, which is by no means as good as a target trigger on an air rifle. Even so, we see accuracy that any 10-meter precision rifle would be proud of.

I think Crosman has made a winning rifle in the MAR177. And when they bring out more powerful versions of it in the future, it’ll be all the greater justification for owning an AR! My thanks to Crosman for the loan of this MAR177 for both this test and for the feature article I am writing for Shotgun News!
