This will be our last look at the Crosman 760 Pumpmaster Classic. It has some surprising results, though not in a good way. But, like so many things, we sometimes learn by doing.

Dot sight

Way back in early February at the end of Part 4 I said I needed to return to this airgun and test it with a dot sight. I half-kidded about using Sig’s Romeo5 XDR that costs 9 times what the 760 costs. I would have done it for a laugh but it proved to be impossible. The Sig sight design is so focused on rifles with Picatinny rails and pistols that accept insert plates that it does not adapt to 11mm rails — even with the UTG 11mm to Weaver adaptor. So I had to find something else. read more

BSA Super Meteor
My rifle is actually a BSA Super Meteor.

This report covers:

• What we’ve learned so far
• Mounting the Tasco Pro-Point dot sight
• 10-meter accuracy RWS Hobby pellets
• JSB Match Diabolo pellets
• H&N Finale Match Pistol pellets
• RWS R 10 Pistol pellets
• The Meteor is good

What we’ve learned so far
I began the review of the BSA Super Meteor in October 2013 — almost a year ago. I acquired the rifle at the Roanoke airgun show (and, no, I don’t know whether or not it will be held again this year) from Don Raitzer, because I’d always wanted to review the rifle. I commented that Meteors had always looked like cheap airguns to me; but after researching them, I discovered they went through the transition period when BSA went from being a world leader in airguns, through several attempts to make their guns less expensive to build and eventually to the point where the company was bought by Gamo.

So, Meteors exist in numerous variations, with Marks I and II being considered the best, and the cheapening started with the Mark III. My Super Meteor is a Mark IV and well down the road from the top quality they enjoyed at their height. But it still does show a lot of innovation in the design. I showed you all of that in the early parts of this report, as I rebuilt the powerplant and crowned the muzzle.

I got the velocity back up to standards, but for some reason the accuracy was never there. I lamented over this in the last few reviews, but it wasn’t until the final part — Part 8 — that I discovered what might have been the problem. And then I guess I must have burned out, because I didn’t return to the rifle until today.

It was Monday’s look at the BSA Scorpion that caused me to look back at the reviews of the Meteor. That was where I discovered that I’d intended to try the rifle with a scope or dot sight but never did. Until today.

What I discovered is that the Meteor’s rear sight is loose and tends to move when the rifle’s shot. I wondered if an optical sight that stayed put might correct any sighting problems and let the rifle reach its true potential. Today, you’ll see what that is, and you can use the links to the earlier parts, above, to see the contrast between the accuracy with open sights and the dot sight I chose for today’s test.

Mounting the Tasco Pro Point dot sight
I mounted a 30mm Tasco Pro Point red dot sight that I’ve used in other tests. Mine is vintage and not at all like today’s Tasco Pro Point. I would have used the Tech Force 90 dot sight, but that one’s being used on another rifle we’ll get to very soon.

Meteor with Tasco mounted
I mounted a vintage Tasco Pro Point dot sight on the BSA Meteor.

Once mounted, the dot sight was very easy to sight-in for 10 meters. I saw tighter groupings at my 12-foot sight-in distance and began to hope I’d solved the problem. Let’s now see how well the rifle did.

10-meter accuracy RWS Hobby pellets
The first pellet I tried was the RWS Hobby that had done best in the previous tests with open sights. Right away, there was a dramatic difference. Ten Hobbys now went into 1.033 inches, where they’d only previously made a best group that measured 1.361 inches with open sights. But inside the big group, 8 shots were in a tight cluster measuring 0.437 inches! This is what I was expecting from the Meteor all along!

RWS Hobby group
Maybe not the tightest 10-meter group, but 8 of these Hobbys went into 0.437 inches, giving me hope for the rifle.

JSB Match Diabolo pellets
Because no other pellet had done as well as Hobbys in previous testing, I decided to change my choices and concentrate on several target pellets. Next up was JSB Match Diabolo wadcutters. Ten of them went into 0.681 inches — with no fliers. Now we’re getting some results!

JSB Match wadcutter group
Now we’re talking! Ten JSB Match pellets made this 0.618-inch group at 10 meters.

H&N Finale Match Pistol pellets
The next pellet I tried was the H&N Finale Match Pistol pellet. This one proved to be the most accurate of this test. Ten went into a 10-meter group that measures 0.456 inches between centers.

Before we begin today’s report, a word about my late friend, Earl (Mac) McDonald. His family has set up a memorial page in his name to collect finds for research into the causes of Creutzfeldt-Jakob disease, which is one of the names prion disease goes by. Most of you knew Mac only through his writing and testing here on the blog; but a few of you were friends with him through this hobby, and I thought you would like to know about this.

Today, we’ll continue testing the Benjamin Trail NP pistol. Although today’s title says Part 5, it’s actually the 6th report because I had to break Part 4 into sub-parts a and b.

We’ll look at the accuracy of those 3 lead-free pellets that Crosman provided with the test pistol. As before, I’m shooting at 10 meters, and the gun has a red dot sight mounted. I’ll describe all the other shooting conditions as we go. It has been so long since I last tested this air pistol that I had to read both parts of the fourth report to find out how to shoot the pistol for the best results.

I decided to shoot everything with the cocking aid attached. My testing demonstrated that it didn’t hurt the accuracy, and in a few cases it seemed to help it. At any rate, it makes the pistol easier to cock, so I left it on for this whole test.

Crosman Powershot Penetrators
The first pellet I tested was the Crosman Powershot Penetrator. It’s a synthetic-bodied pellet with a heavy non-lead metal core. They fit loosely in the breech, so I seated them flush but did not try to seat them deep. Since some of my best shooting was with the gun rested directly against the sandbag last time, I decided to start out that way. Imagine my surprise to see a near-pinwheel shot with the first pellet! [A pinwheel is a shot in the exact center of the target, and it refers to taking out the extremely small 10-ring of a smallbore target so that just the white scoring ring remains behind.] The shot was so good that I stopped and took a picture of it to show you — in case history was about to be made. This happens about one time every ten thousand shots or so for me, and it’s usually by pure chance. It is, however, the sort of thing that gives rise to lies and legends and is probably the basis for the Cargo Cults.

Benjamin Trail NP pistol
Just in case I was about to make history, I photographed the first shot of the Benjamin Trail NP pistol with Crosman Powershot Penetrators.

Shot No. 2 (at the bottom of the picture) made it clear that the first shot was a happy accident. Resting the pistol directly on the sandbag was not the thing to do!

Much as I would have loved to bask in the radiance of that first shot, shot No. 2 dispelled the miracle. Pellet 2 landed 4 inches south of the first one, humbling me once more.

Here’s a lesson in testing airguns. When something goes wrong like this, and all your experience says that it should have been wrong to begin with (resting a spring gun directly on a sandbag), take the hint and change your ways. So I did. I moved my hands forward of the bag and held the gun with no part of it touching anything except me. Then, I shot 10 more shots into a very decent group that measures 1.587 inches between centers. In the grand scheme of things, it’s not a bad group for this pistol. Not the best by any means; but for lead-free pellets, it’s not bad.

Resting the arms on the sandbag and holding the pistol free was the way to go. Ten flush-seated Powershot Penetrators made this 1.587-inch group at 10 meters.

Crosman SSP hollowpoints
Next, I tried the SSP hollowpoint pellets seated flush and with my arms resting on the bag but the pistol not touching it. This was how I held the gun for the remainder of this report. This time, 10 pellets made a slightly smaller group — measuring 1.513 inches. Amazing! Who would have thought that lead-free pellets could be so accurate?

Before I begin today’s report, I have sad news. Our friend Earl “Mac” McDonald passed away on Sunday, May 5, at 4:30 a.m. He was surrounded by his family.

Mac was diagnosed with a prion disease in April of this year. I don’t want to discuss it here, but if you want to know more, here is a link. This disease affects one person in a million. It is not only very rare, but the cause wasn’t even discovered until the 1980s. Scientists are still unsure of all the details.

I was aware of the probable diagnosis when I went to visit Mac last month but was asked not to disclose the details. Fortunately, when I arrived, he was able to recognize me. I sat with him and talked about old times whenever he was awake. My wife, Edith, and our friend Otho Skyped with Mac. Via the computer, Edith showed Mac the SHOT Show report in Shotgun News, which was the last thing he photographed for me.

Like everyone who knew him, I’m saddened by his passing — but that is more than offset by the pleasure of knowing him as long as I did. The fact that he was able to attend this year’s SHOT Show was especially rewarding.

As this blog moves forward, I will occasionally refer to Mac and some of the things he did. The best memorial I can give him is to never forget the time he was here.

Today’s report
I left you with a cliffhanger last Friday — more than I imagined, as it turned out, because I thought I was writing Thursday’s report and would publish the second part on Friday, rather than today. I know you all want to know what happened when I seated the H&N Finale Match Pistol pellets deep in the bore with the cocking aid attached and rested the pistol directly on the sandbag.

If you were expecting a Cinderella story, it didn’t quite happen. The group got measurably better — in fact, it was the second-best group of the test to this point. Ten shots made a group measuring 1.105 inches between centers. Compared to the previous group, which was larger than 2 inches, it seemed clear that this was the best way to shoot this pellet — deep-seated, gun rested on the bag and the cocking adapter attached.

Ten shots with H&N Finale Match Pistol pellets seated deep with the cocking aid attached and the gun rested directly on the bag made this 1.105-inch group. So, deep-seating these pellets reduced the group size by half.

Did you possibly think that it put all 10 into the same dime-sized hole that the 5 good ones went into on the previous test? I hoped that would happen, too, but it didn’t.

Not H.P.White Labs
Before you start looking back at all the testing done on this pistol to-date to recommend different things for me to test, let me say I am not H.P. White Laboratory, and the goal of this test is not to see how accurate the Benjamin Trail NP pistol can possibly be. My purpose is to evaluate the pistol as it comes from the box, so those thinking of making a purchase will have something to go on. I think I’ve done that already, and the gun is definitely worth the money. But the test is far from finished.

Air Venturi Pellet Seater
Blog reader Nomobux asked me how deep I seated the pellets with the Air Venturi Pellet Pen and Pellet Seater. Well, that varies, based on how thin the pellet skirts are. But I measured the seater with the pin protruding by 0.163 inches, which seated the pellets about 0.125 inches deep.

I set the pellet seater to this depth months ago and have been using it this way ever since.

Crosman Destroyers
A blog reader asked me to test Crosman Destroyers — a new hollowpoint that has a large open cavity in the nose. Since I was playing, I decided to shoot 5 shots and see if it was worth finishing the group. With the pellets seated deep, the cocking aid attached and the gun rested directly on the bag, 5 shots made a group measuring 2.546 inches, so I stopped there. Since that was already very large and 5 more shots would not make it any smaller I decided to save my time and effort.

Five shots with Crosman Destroyer pellets seated deep with the cocking aid attached and the gun rested directly on the bag made this 2.546-inch group. I stopped after 5 shots because the group was already too large.

But I also figured some of you wouldn’t let me rest if I didn’t test at least one more variable with this pellet, so I shot it seated flush, as well. Surprise! It turned out better. Ten shots went into 2.086 inches. That’s not a world-beater group, I know, but it is better than the 5 shots with deep-seated pellets. It points out that deep seating has to be evaluated on a case-by-case basis.

Today we’ll make blog history. This is the first half of a 2-part report on the Benjamin Trail NP pistol. I was shooting it yesterday and found myself going in so many directions that I collected too much data for a single report. So the second half of today’s report will come on Monday.

I told you in the last report that I decided to “play” with the pistol rather than subject it to a rigidly structured test. Well, that must be catching because I did it again today. Something about this air pistol seems to invite experimentation.

It doesn’t have to shoot low!
I said that it shot too low in the last report. It did, but I was using the sights in a way the manufacturer did not intend by using the tip of the front sight for a 6 o’clock hold. That caused the gun to shoot a little low by itself. But, today, I replaced the rear sight with a red dot sight and found that the gun can shoot to the point of aim with ease. In fact, I had to adjust the sights down, but I will talk about that later.

I mounted a Tasco Pro Point dot sight on the 11mm dovetails that are on the rear of the spring tube. You could use anything that has a decent amount of adjustability.

This old Tasco Pro Point dot sight installed on the Trail NP pistol without a fuss. It brought the point of aim and point of impact together.

It’s so much easier using a dot sight because there’s just the dot and target to watch, instead of the sight alignment. Shooting the pistol was much easier.

The first pellet: RWS Hobby
In the last test, RWS Hobby pellets were the most accurate, so those were the first pellets I tested this time. That made it simpler to test the gun because I knew I was starting with a reasonably accurate pellet.

And because this will become important in a while, let me tell you that these first groups were shot without the cocking aid on the gun. It’s a little harder to cock without the aid, but installing and removing it for every shot takes too much time.

The first group surprised me, because it wasn’t as good as it was the last time I tested this pistol. The first shot was a low flier caused by my unfamiliarity with the dot sight; but after that, all the rest of the shots were the best I could do. I think the measurement for 9 shots is more representative in this case, and let’s exclude that one low shot.

Nine shots went into a group that measures 2.04 inches between centers. That’s still larger than the group I got with open sights, which is 10 in 1.155 inches. I wondered if some of the stock screws might have loosened in all the shooting. I checked, and they certainly had. I tightened all stock screws; but instead of running the same test again, I proceeded to the next test. How would the pistol respond to pellets seated deeply with the Air Venturi Pellet Pen and Pellet Seater?

Benjamin Trail NP pistol RWS Hobby group flush
The lower shot is a called flier resulting from an improper sight picture. Nine pellets went into 2.04 inches at 10 meters.

Deep-seated pellets
Not only did the group improve measurably, the point of impact rose by two inches when I seated the pellets deep into the breech with the pellet seater. This pellet seater is really proving to be a valuable piece of equipment when used on certain guns — like this one. And this rise in the point of impact is why I say there’s no problem with the Trail NP shooting low. You simply need to seat the pellets deeply.

This time, 10 RWS Hobbys went into 1.025 inches between centers. That’s remarkably close to what I did last time with open sights, but just a trifle better.

Benjamin Trail NP pistol RWS Hobby group deep-seated
Deep-seated pellets made the difference. Ten went into 1.025 inches at 10 meters, and the point of impact raised by over two inches. Deep-seating is the trick, then.

Since deep-seating seemed to produce such good results, I decided to seat all pellets from this point, on. For my next test, blog reader Victor suggested that I try some good competition pellets. He recommended some H&N pellets, so I selected H&N Finale Match Pistol pellets. I seated them deep and proceeded with the test. But, oh, my, they didn’t do well at all! At least not when taken as a whole.

Victor, Victor! Where did we go wrong? Ten H&N Finale Match Pistol pellets made a 2.008-inch group. But look at the 5 in the middle. Perhaps there’s hope. read more
