Umarex Trevox air pistol
The Umarex Trevox is a single shot breakbarrel gas spring air pistol.

This report covers:

  • The test
  • Trigger
  • JSB Exact 10.34-grain
  • Sig Match Ballistic Alloy
  • RWS Hobby
  • Last test
  • Sights
  • Evaluation
  • Summary

Today we test the accuracy of the new Umarex Trevox air pistol. I like this pistol so far, so if it is accurate it is a best buy.

The test

I shot off a sandbag rest from 10 meters. I rested the bottom of the grip on the bag for most of the test to take up the pistol’s weight, though I did try it completely handheld. I will describe both holds as we go.

Trigger

The trigger pull reared its ugly head during this test. The pull is long and stacks up toward the end. I think the pull opened some of the groups a little. read more

  • Summary

Today we see the accuracy potential of the Hy Score 816/Diana model 6 target air pistol I recently acquired. We had a good indication from the first group it shot.

target
This group of 5 Sig Match Ballistic Alloy pellets measured 0.338-inches. Shot at 10 meters.

The test

I shot off a sandbag rest from 10 meters. The Giss counter-recoil system allows for resting the pistol directly on the bag. Despite all my complaining, I shot with the pointed sight insert I showed you in Part 1. I did have a problem with it, but it wasn’t the sight’s fault and I will explain when I get to it. read more

This report covers:

  • RWS Hobby
  • Qiang Yuan Training pellets
  • Trigger improved
  • Sig Match Ballistic Alloy
  • Cocking effort
  • Trigger pull
  • I goofed on the trigger
  • Summary

Today we look at the velocity of my new/old Diana model 6 target pistol. There was a lot of interest in this gun last Friday — more than I expected. I really do feel fortunate to have acquired it. Now that I’ve learned that a reseal could cost over $200 with shipping, I really hope this one is doing okay! Let’s find out together.

RWS Hobby

First up is the lead lightweight, the RWS Hobby wadcutter. These are often the fastest lead pellets in an airgun, though my Diana model 5 actually shot a heavier target pellet faster. Let’s see what this pistol does. read more

  • The real world

It’s Friday and you now know what pistol shot that small group this week. It was a Hy Score 816 that’s actually a Diana model 6 target pistol. I had told you that I won this auction on Gun Broker. In fact, let’s look at what I said.

A seller had listed a Hy Score model 816 pistol for $119.99. Now, if you have listened to reader ChrisUSA, you have purchased your Blue Book of Airguns that has a manufacturer cross-reference table in the back. Hy Score was based in Brooklyn and did manufacture some airguns in the 1940s through the ’60s. They also bought airguns made by other companies that were marked with their name — not unlike business is done today. One company they bought from was Diana. I search Hy Score listings frequently, hoping to stumble across a model 807 rifle which is really — quick, someone tell me! That’s right, it’s a Diana model 27. read more

  • Pellets jamming
  • Trigger pull changed
  • Sig Match Ballistic Alloy
  • RWS Superdome

  • Open sights visible?
  • RWS Superdomes through the magazine
  • Discussion
  • Surprise!

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


Ten-meter accuracy test — Daisy 499 versus Haenel 310

by Tom Gaylord
Writing as B.B. Pelletier

A history of airguns

This report covers:

  • Another failure!
  • The test
  • 499
  • Discussion 1
  • Haenel 310
  • Discussion 2
  • CZ75 P-07 Duty accuracy at 10 meters
  • Summary

I put today’s report in the historical section because it relates to both the Haenel 310 and the Diana model 30 that we tested recently. In the comments to the Diana 30 test the question was raised about which would be more accurate at 10 meters — the Daisy 499 Challenger or the Haenel model 310. I said I thought the 310 would beat the 499 because it is rifled, but several readers wanted to see. So, today we see.

Another failure!

Before I get to the results of today’s test, let me fill you in on another irony. I was going to test the accuracy of the Benjamin 700 today and the gun jammed as I started to shoot. This one has a happy ending, because I got it unjammed and working again, but that was after today’s test. There is more sweet irony in the story that unfolded there, but I will hold off on that until we get to the report. read more

Today is a mistake. Reader RidgeRunner asked me if I intended to finish this report from 2008. I looked at his link to Part 5 and, sure enough, it looked like I had intended to. I even promised a reader back then that I would. Well, WordPress software is at fault this time, because I did not find a later report when I entered it in the search box at the top of this page, but when I went to publish this report number 6 I found that one had already been published — on July 22, 2008. But that was after I did the complete test plus some extra things, so I’m going to finish it again. It’s actually a good report. And by the way, I just entered the title in the search box again and this time it came up. Of course it did! read more
