General information

Before I start today’s report I have a number of things I want to cover. First, I realize I am behind on a number of reports from the 50-yard line. I’ve been unable to get to the range for many weeks for various reasons, and when I did get to go before that, the wind was too high for airgun testing. I want to test the pellet shapes at 50 yards, the .25 caliber Marauder I had tuned, a new AirForce .357 Texan (I have a lot of things to do with that one), and now guns like the Galahad will soon be stacked up.

I have received the adaptors for shooting pellets in my AR-15 and that’s another one I think will have to be done outside because of the noise, though they say the report is quiet. I also got an adaptor to shoot .32 pistol rounds in my Mosin Nagant rifle, which I thought would be a nice addition to that report on adaptors.

This report covers:

  • Shoot left-handed
  • RWS Superpoints
  • JSB Exact RS
  • RWS Superdomes
  • Now, for the mind-blower!
  • The underlever latch
  • Trigger adjustment
  • Evaluation

Keep him off his his computer, ladies, because today I’m the Great Enabler! Today I shoot the Diana K98 pellet rifle at 25 yards with open sights. And when he sees the results, he’s going to want one!

Shoot left-handed

Today was accuracy day at 25 yards and I absolutely could not see the bull, when sighting with my right eye — even when wearing my glasses! So I had to switch hands and shoot from the left side.

RWS Superpoints

The first pellet I tried for no particular reason was the RWS Superpoint. One shot confirmed I was on target, then the next 9 went downrange without checking. I walked down to change targets and saw the group for the first time. Ten shots in 2.32-inches! The “group” was very horizontal. Not a good start.

This report covers:

  • Artillery hold
  • JSB Exact RS
  • RWS Superpoint
  • Slippery butt plate
  • Cocking effort
  • RWS Hobby
  • Shot cycle
  • Cocking lever latch
  • Results
  • Next

Today is the first of what are sure to be several accuracy days with the Diana K98 air rifle. I started slow, shooting from 10 meters off a bag and using open sights. I shot off a bag, but I did use the artillery hold. After the test it occurred to me that I should have tried a group with the rifle rested directly on the bag, but it was too late. I will do that in a future test.

As I shot the rifle I concentrated on several comments made by reader, Zimbabwe Ed. Ed has had some negative experiences with his K98, so I will address those as I go.

What is accuracy?: Part 2

by Tom Gaylord
Writing as B.B. Pelletier

Part 1

This report covers:

  • Pellet head size
  • Barrel crown
  • BSA Meteor .177 caliber
  • Gun vibration
  • A case for the PCP
  • Barrel size
  • Choke
  • The right pellet
  • Summary

This report started in the historical section, but today I’m moving it into the mainstream reports. Tuesday I talked about why some new air rifles don’t shoot well. Today the topic is broadened to all airguns.

In Part 1 we learned about all that Dr. Mann did in his 37-year quest to discover why all bullets don’t go into the same hole every time. In that report we learned that things people think work for accuracy, like clamping a gun in a vise, don’t always help.

Today I’m going to talk about accuracy with pellet guns. Dr. Mann showed us that pellets (bullets) will never go to the same place every time, no matter what you do. But what helps bring them together? Why are some airguns accurate and others are not?

  • JSB Exact RS

  • Loading is fiddly
  • Evaluation so far

Today is the day I test the velocity of the Diana K98 air rifle for you. A lot has been written about these rifles. Much of it has been good, but there have been a few comments that were not so good. One of them was from one of our readers who got his rifle before I got mine and he reports things like hard cocking and difficult loading because of the placement of the rear sight. He also takes exception to the location of the sling on the left side of the rifle, but that is a Mauser design and had to be put there to match the firearm. I won’t comment on that, except to say that a Mauser sling makes a rifle easier to carry while slung than a Springfield-type sling, but not as convenient for shooting as a hasty sling (look it up).

Why won’t my new air rifle shoot well?

by Tom Gaylord

Writing as B.B. Pelletier

This report covers:

  • The barrel
  • AirForce Texan .357
  • Is JB Bore Paste safe in a barrel?
  • Why haven’t we heard of this before?
  • What is the accuracy limit?
  • What about brass barrels?
  • Leather shoes
  • What have we learned?

I have been writing this blog for going on 12 years, and before that I wrote The Airgun Letter newsletter for 9 years. In that time I have talked to thousands of new shooters about the accuracy (or lack of accuracy) of their new airguns. This subject comes up more with rifles than pistols, because when a pistol is inaccurate most people blame themselves. But what I am about to tell you holds true for all guns that have rifled barrels.

Today’s blog was prompted by a new reader who calls himself Geo Johnson. George has an RWS Diana 34 that he is having accuracy problems with. We went through the artillery hold, and since I can’t see him shoot I have to take his word that he is doing it right. It makes all the difference in the world if he is putting any pressure on the stock as the rifle fires, but I will assume he is not. I know that a Diana 34 is a very accurate air rifle, so what else could cause it to not be accurate? Loose screws are a possibility, but they are quickly checked.

A history of airguns

This report covers:

  • The test
  • Sight-in
  • RWS Superpoints
  • Open sights
  • Is it my eye?
  • Eley Wasps
  • The eyes have it
  • Next?

Today is the first accuracy day for my new .22 caliber BSA Airsporter Mark IV. As the picture shows, it came with an old Dianawerk scope mounted, and I said I would test it with that first. So that’s what I did.

The test

Today I shot off a sandbag at 10 meters, just to get familiar with the rifle. I tried it both using the artillery hold and directly rested on the bag. The first groups were shot using the scope.

Sight-in

The scope was not exactly on target like I had hoped, but it was close enough on the first shot that I adjusted it to hit near the POI. The scope is not adjusted for parallax as close as 10 meters so the image is fuzzy. The reticle is a German hunting reticle with three heavy black lines — two on either side and a pointer coming up from the bottom. You put the tip of the pointer on the target when hunting, but it gets lost on a black bull, so I set it at 6 o’clock.
