BAM B51 – Part 2 A look at the “Chuntsman”

by B.B. Pelletier

Part 1

Well, a very interesting day. You will recall that yesterday I checked the pressure in the BAM B51 and used a hand pump to add another 100 psi. I wasn’t sure that it was needed, because the gauge I used yesterday was different than the one I used to fill it initially a week earlier.

Out to the range
I packed up all my gear – rifle, targets, pellets, bench bag, carbon fiber tank, a pump to back that up, chronograph and skyscreens and shooting bench – and drove to the range. Got there, set up everything and decided to chronograph some pellets first. First shot with .22-caliber Beeman Kodiaks didn’t trigger the skyscreens, but the sound it made was similar to a blowgun being fired, as in very quiet. That’s never a good sign with an unsilenced PCP. Next shot registered 383 f.p.s. I knew for sure something was wrong.

BAM B51 – Part 1 A look at the “Chuntsman”

by B.B. Pelletier

Before we begin today’s post, I have to comment on the recent test of the RWS Diana 460 Magnum. This air rifle now tops the list as the No. 1 “trigger” gun in this blog. By that, I mean it triggered more responses than any other airgun. Based on all the comments, I have ordered a .22 caliber rifle to complete the look.

For the gentleman who wondered when I would be testing the RWS Diana 350 Magnum, I already did – back in February of 2006. Read the report.

For those who criticized the low velocities I reported, didn’t you read the other TWO velocity tests I reported? Both were considerably faster than my test rifle, and in the general realm of the advertised velocity. We need to get past this hype of velocity in a spring gun because it is meaningless without accuracy. And, the 460 is accurate. Compare the accuracy of the Gamo Hunter Extreme to the accuracy of the 460. The 460 is as accurate at 35 yards as the Hunter Extreme is at 25.

RWS Diana 460 Magnum – Part 3

Part 2
Part 1

Drum roll, please. Today, we’ll look at the velocity and power of the RWS Diana 460 Magnum. I know this is a big deal for a lot of people, but I have to say that after seeing how accurate it is, I don’t really care what the power turns out to be. Oh, and by the way, I’m testing a .177. I should have told you that in the first installment.

First up – Beeman Kodiaks
The Beeman Kodiak 10.6-grain pellet was the most accurate in the test rifle. Not only that, but it left all the others in the dust. I didn’t test each and every pellet for velocity – just a few important ones. Kodiaks average 822 f.p.s., with a spread from 817 to 826. That works out to a muzzle energy of 15.91 foot-pounds.

RWS Diana 460 Magnum – Part 2

Part 1

There was a good response to my question about a scope primer, so I will do it. I’ve probably written most of this stuff before, but this time I’ll write it with an eye toward chapters in a small book. Thanks for your input.

Scopestop asked me for links to all the scope posts I’ve made. Here are about half of them:
Sighting in a scope – Don’t get carried away
Where (and how) to locate a scope
Scope mounting height
Adjustable scope mounts
Another problem with scopes: Not mounting them correctly
Shooting with a pistol scope
Adjusting a scope
At what range should you zero your scope?
What causes scope shift?
Another cause of scope shift: over-adjusted scope knobs
More about sighting-in: How to determine the two intersection points
How to optically center a scope

RWS Diana 460 Magnum – Part 1

by B.B. Pelletier

Before I begin today’s topic, I have a question. Pyramyd Air is getting several product reviews in which the writer says he’s having trouble with his gun AFTER he mounts a scope. Before the scope, the gun shoots great. After the scope, it is inaccurate. One writer even said his gun was inaccurate until several friends tried it and got good groups. Then he decided he needed to learn how to shoot with a scope.

These comments tell me many shooters don’t really know how a scope sight works. They mount it on their rifle – often improperly – then assume the gun will hit whatever they place the crosshairs on. I’m not kidding!

BB’s yard sale!

Mendoza aperture sight is well-made and a heck of a bargain!

Okay, something different today. Instead of a gun or accessory review, how about some inside information! In fact, how about a whole bunch of it?

Item 1. Mendoza sights
My long time readers know that when I tell you about a deal, it’s for real. Well, here comes a deal! Mendoza makes a diopter sight that compares favorably with the Beeman Sport Aperture sight, which retails for $63.25. When Pyramyd Air purchased Airgun Express, they bought a lot of these sights, and they’re just now making it to the website. The price of $19.99 is in line with Beeman’s price for their sight back in the 1970s! I have held this sight in my hand at the SHOT Show and worked the adjustment mechanism; it’s just as crisp as the Beeman. I’m buying 2 to put away for the future.

UTG Shadow Ops Type 96 sniper rifle – Part 2

by B.B. Pelletier

Part 1

Let’s get right to it. I’m impressed by the function and quality of this sniper rifle. Less than five years ago, I critically tested a Classic Army M24 sniper rifle very similar in performance to this gun. That one sold for close to $300 new, then had about $800 of extensive gunsmithing done, but it wasn’t as nice as the UTG Shadow Ops Type 96 from the box.

For starters, the Classic Army had a 190 mainspring and powerplant upgrade to get it up to the same velocity this rifle gets from the beginning. That made the bolt extremely difficult to operate (I can’t remember whether it cocked on opening or closing). The UTG Shadow Ops Type 96 is very nearly as easy to cock as the Marui VSR-10 G-Spec, which is to say, very easy, indeed. And, it gets 160 f.p.s. higher velocity than the Marui at the same time! That’s what I find fascinating.
