Gletcher Nagant CO2 BB revolver

This report covers:

Grip won’t go on
First group
Deep seating for accuracy
Umarex BBs
4.4mm lead balls
Daisy BBs, again
Evaluation
The action works with the loading gate down

We’ll look at the accuracy of the Nagant CO2 BB revolver today. I learned a good tip for improved accuracy, and I’ll also show you how the action of the revolver I am testing works with the loading gate open. Let’s get to it.

Grip won’t go on

The first thing I did was install a fresh CO2 cartridge. And I had the same problem I reported in part 2 of getting the grip back on the gun after the cartridge was in place. But this time, no matter what I did, it wouldn’t fit on the gun.

I shot the test with the left grip panel off, then removed the Crosman CO2 cartridge and tried installing an ASG Ultrair CO2 cartridge. Problem fixed!

Diana N-TEC 340 Classic air rifle

Part 1
Part 2

This report covers:

Baracuda Match pellets, 4.50mm head
Baracuda Match pellets, 4.53mm head
RWS Superdome pellets
Fast action
Learning the trigger
JSB Exact heavy pellets, 10.34 grains
The bottom line — so far

Let’s start looking at the accuracy of the Diana 340 N-TEC Classic rifle. I used the open sights that come on the rifle, and I shot at 10 meters today. I did that because air rifles with gas springs are, in my experience, not all that accurate. I did feel the 340 N-TEC is a different breed of gas-spring rifle, but I wanted to play it safe. So, 10 meters off a rest.

Baracuda Match pellets, 4.50mm head

The first pellet I shot was the H&N Baracuda with a 4.50mm head. It hit the target a little high and to the left; so, after shooting the group, I adjusted the sights.

Quick notes

Thank you for being patient in April. It was a busy month for me!

Now that the last event is over, I’ll get back to accuracy tests for both the Benjamin Bulldog and the Hatsan BT-65. I now have additional bullets for the Bulldog and additional pellets for the Hatsan, so this should be good. I hope to get to the range later this week with both of those rifles.

I finally got my HW 35 at the Malvern airgun show, and it came with a big surprise. The rifle has been tuned! From the feel of it, the tune was a good one; but, of course, I need to test it thoroughly to know for sure. I had plans for tuning the rifle after my basic test, but now those plans will hinge on how well the rifle is already shooting. I may leave it as it is. I hope it’s also accurate.

2015 Malvern airgun show: Part 1

This report covers:

Layers of intrigue
Seth’s bullets
Rocket Shot
AirForce Airguns Texan big bore air rifle
Dennis Quackenbush
Mike Melick
Pellet Head Gauge
RAI
WOW!

Malvern is a show that has evolved over the years. Originally, it was the Little Rock, Arkansas, show and was held in Benton, Arkansas, inside an empty mall building for many years. Then, it moved a few miles to the west to the county fairgrounds for several more years before the promoter decided to give up the show.

Layers of intrigue

Seth Rowland, who makes bullets for big bore hunters, took over promoting the show and moved it to the old country fairgrounds in Malvern, Arkansas, about 20 miles further west on Interstate 30. Of all the airgun shows being held, Malvern is the smallest and the quietest, but it’s also one that has many surprises every year. This year, I’ll say that I saw layers of intrigue to the show. That’s what I’ll discuss today.

Ballistic coefficient: What is it? Part 2

Part 1

This report covers:

Review
Today’s discussion
Round balls
Conical bullets
Smokeless powder
A big point
Shape
Round balls — again
The bottom line

I’ve taken 11 months to return to this subject of ballistic coefficients (BC). That was in spite of some tremendous interest in Part 1 of this report last May.

I’m purposely avoiding all discussion of mathematics, which is difficult, since ballistics is a discipline that heavily employs mathematics. But I’m not qualified to write about the math; and, more importantly, I know that 99 percent of my readers would be turned off if I were to write the report that way.

Review

Last time we learned that the BC of a pellet:

• Is an extremely small decimal fraction compared to the BC of a conical bullet.
• Varies with the velocity of the pellet.
• Varies with the shape (form) of the pellet.

Part 1

Gletcher Nagant CO2 BB revolver

This report covers:

No safety
Some problems with the CO2
Second cartridge
Velocity
Daisy BBs
Crosman Copperhead BBs
Shot count
Sound
Trigger-pull
Evaluation so far

Today, we’ll look at the Gletcher Nagant CO2 BB revolver. We’ll check the velocity, the trigger-pull, and one or two other things that might come up with this interesting BB gun.

Some of you said you own Nagant revolvers and were glad to see this BB revolver. This is one time when I feel ill at ease with you readers, because I don’t have any experience with the firearm. Of course, the gun I’m testing is a BB gun that differs from the firearm, so I can learn as we go.

No safety

Someone asked if this revolver has a safety, and that started a discussion on revolver safeties. The Nagant revolver does not have a safety on either the firearm or the CO2 BB gun.

H&N Hornet pellet: Part 2

We’ve closed down comments on this blog report as of May 4, 2015. When we have a chance to remove the political attack comments, we’ll open this up again for comments.

Part 1

H&N Hornet pellets

This report covers:

The first test
Today’s test
On to the Hornet
What’s next?
2015 Pyramyd Air Cup

Readers suggested I test the Hornet in my TX200 Mark III. I could do that, and it would be easier than the rifle I chose to use for today’s test. But is it realistic? Most readers don’t own a TX and won’t buy one. I chose to test the pellet at high power in my Diana RWS 34P — a rifle of incredible accuracy when the correct hold is used. This is an air rifle that many more shooters around the world are likely to own.
