Today is accuracy day for the Diana Chaser air pistol. I threw in some extra tests just for fun. This should be interesting, so let’s go!

The test

I shot off a sandbag rest at 10 meters. I used the single shot tray for the first 4 groups, then switched to the magazine for the final group. There were some interesting results that I couldn’t have predicted.

Qiang Yuan Match pellets

I shot the first group with Qiang Yuan Match pellets. No particular reason for that, other than I had them ready. They hit the target low and to the left, but I left the sights where they were and shot all 10 pellets. They landed in a group that measures 1.052-inches between centers. This was larger than I had hoped for the Chaser. read more

This report covers:

  • Smoothbore Diana 25
  • The $100 PCP
  • The best article
  • Smoothbore rifle
  • Birth of the smoothbore rifle
  • The results
  • All balls spin in flight
  • Consistency
  • What have I just said?
  • Summary

I don’t like to use myself or this blog as an authoritative source, but when I research shooting round balls at high speed I find that I have written more on the subject than any other source. Or maybe not more so much as more that has been verified.

Smoothbore Diana 25

To get you started, read this 5-part report on the Diana model 25 smoothbore. Reading that you will discover several things. First, that smoothbore airguns are accurate out to 10 meters when shooting pellets. Next — it takes the right loading technique to shoot a pellet accurately from that airgun at 10 meters. We also learned that the same gun fell apart when the range was increased to 25 yards and shot the same pellets that were accurate at 10 meters. Finally we saw that round balls in this gun were not accurate at all. read more

Sig Sauer X-Five pellet pistol: Part 2

Part 1

Sig P226 X-Five
Sig’s X-Five pellet pistol.

This report covers:

  • X-Five P320 or P226?
  • Velocity — RWS Hobby
  • Velocity — SIG Match Ballistic Alloy
  • Velocity — JSB Exact RS
  • Will the X-Five shoot BBs?
  • Velocity — Dust Devils
  • Shot count
  • Trigger pull
  • Evaluation

Today we look at the velocity of the new Sig Sauer X-Five pellet pistol. I told you in Part 1 that the firearm version of this airgun is now on my bucket list. Here is why. The X-series Sig pistols have all been through Sig’s Custom Shop, where their triggers have been tuned to perfection and where their parts have been hand-fitted to achieve accuracy that was once just the claim of the legendary Sig P210.

Most readers know that I am a handgunner at heart. I grew up longing for the most accurate handguns available, and all my life the Sig P210 has been one of them. It rivals S&W and Colt revolvers and accurized 1911s. And they cost accordingly. The Sig X-Five will cost just under $1,700. That’s not cheap by any means, but compared to what a vintage P210 costs, it’s very reasonable. read more

This report covers:

  • The test
  • Trigger
  • The test
  • Accuracy — JSB Exact RS
  • Accuracy— JSB Exact Heavy
  • Accuracy— Crosman Premier Light
  • What next?
  • Final group
  • Evaluation
  • Summary

Today I complete the report on the Forge from Umarex. This is a breakbarrel rifle with a gas spring and … Well, you can read the past posts to catch up.

I’m running this test because the last time we looked at the Forge I felt the poor 4X32 scope that was provided with it might not have extracted all the accuracy the rifle can produce. I vowed to return and test it with a better scope and today the Force is mounted with the Aeon 8-32 AO scope with trajectory reticle, which is one of the best scopes I own. You can read about it here.

The test

This will be 10 shots with each pellet from a rested rifle at 25 yards. I started with the conventional artillery hold but soon discovered the Forge can be rested directly on the sandbag. I used the artillery hold in the last test, so that may make a difference today. read more

  • On a roll?
  • Air Arms Falcon
  • POI change
  • RWS R10
  • Best for last

  • Summary

Today was day of learning, or perhaps I should say remembering, because today’s test of the Chinese B3 underlever took me back to my early days with spring-piston air rifles. I will explain as the report unfolds.

Refresher

I found this tired old air rifle in a pawn shop many months ago. In this series I have replaced the breech seal with a faucet washer, opened up the powerplant, lubricated the moving parts with Tune in a Tube and shot the rifle for accuracy. That was when I discovered how accurate this old Chinese underlever is. So I vowed to shoot it for accuracy once more, now that the powerplant has been tamed. read more

An announcement

This morning I shaved with a straight razor in a completely different way, after reading a book about shaving that was written in 1905. While very different from anything I had been doing, it all sounded very good and authoritative until I tried it. Then I needed a pint of blood after finishing! The author of this book says many things that run contrary to conventional wisdom and what is being taught today.

As a result of this experience, I have decided that there is more to sharpening a straight razor than I thought. There will be another report coming in which I examine some of the facts and some old wive’s tales about sharpening straight razors. I will try to show you the results more graphically. I don’t want to wreck the surprises that I hope are coming, so that is all I will say at this time. Let’s now turn our attention to today’s report. read more

Hatsan Sortie

Hatsan Sortie precharged pistol.

Part 1

This report covers:

  • Three magazines
  • Filling
  • RWS Superdome
  • Loading
  • H&N Field Target Trophy (5.55mm)
  • Hand pump
  • JSB Exact RS
  • Discharge sound
  • Is this a semiautomatic?
  • Trigger
  • Evaluation so far

Today we look at the power of the new Hatsan Sortie semiautomatic air pistol. I told you in Part 1 that it is a 12 foot-pound gun, so the discharge sound shouldn’t be too great, but we will find out today.

Three magazines

I didn’t show you the stuff that comes with the gun in Part 1, so let’s look at it now. First and foremost, there are three magazines in the box with the pistol. That’s very generous of Hatsan, and the two extras save you about 50 dollars! You also get a fill probe and a set of o-rings and a seal for the gun.
