Scoping problematic airguns

This report covers:

  • The problems
  • Problem 1 — All rifles are droopers!
  • Problem 2 — horizontal alignment
  • Problem 3 — scope eyepiece is in the wrong place
  • What is the solution?
  • Clearance
  • Summary

Today’s report was partly inspired by reader Decksniper, who asked this about the Seneca Aspen rifle:

“I am interested in the shim you used to mount the Bugbuster on the too narrow dovetail. A closeup picture would be helpful.”

I told him I would photograph the shim in the next part about the Aspen, and I will, but this morning (yesterday for you) I was faced with scoping another rifle — the Diana Stormrider Generation II PCP, and it suddenly dawned on me that scoping airguns is one of the biggest challenges I face in writing this blog. As I pondered that it occurred to me that scoping guns is a challenge for all of us. Some may not have realized what a challenge it is because they have become adept in avoiding the problem altogether, but a challenge it is. read more

Hatsan 135 30 caliber rifle
Hatsan’s .30 caliber 135 QE Vortex is a large breakbarrel — both in size and caliber.

This report covers:

  • Today
  • The range
  • The test
  • Pellet drop
  • Predator Polymags
  • Shooting form
  • JSB Exact 50.15-grain domes
  • Discussion
  • JSB 44.75-grain domes
  • Discussion 2
  • Summary

A lot of time has passed since I did the Part 4 report of the Hatsan 135 QE Vortex .30-caliber pellet rifle. I also linked to the Pyramyd Air Cup, Part 2, because that’s where I got to see and shoot Rich Shar’s highly modified Hatsan 135 that’s also a .30 caliber spring rifle. If you don’t read any of the other previous reports I linked to, read that one, because his rifle is the highest evolution of the one I am testing today. It could probably be made as a custom modification, but given what Rich had to do to build it, I think it would cost more than the original rifle by a significant margin. read more

Part 1
Part 2

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

A history of airguns

Hy Score 816
This Hy Score 816 is a Diana model 6 recoilless target pistol. This is the photo from the auction.

This report covers:

  • The test
  • Sig Ballistic Match
  • RWS Super Mag
  • Qiang Yuan Trining pellets
  • H&N Finale Match Light pellets
  • RWS R10
  • RWS Meisterkugeln
  • Why is this happening?
  • Proof
  • 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

Part 1

long shot
The field target match included a number of difficult shots, like this long one.

This report covers:

  • Exotic equipment
  • Timed
  • Other airguns
  • Rich Shar
  • Youth shoot
  • Gunslynger
  • Summary

We’re back to wrap up the Pyramyd Air Cup today. We ended Part 1 with the start of the field target match that surprisingly attracted a lot of reader attention, so that’s where I will begin today.

Exotic equipment

One thing field target brings out is the odd and exotic in many of us. You see equipment you could never imagine! Some of it is not so useful but some things you wish you had invented yourself.

Hector
Hector Medina checks the zero on his Diana 54 that’s been detuned to 12 foot pounds. It’s so easy to cock! read more

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

This report covers:

  • RWS Hobby
  • Discussion
  • JSB Exact Heavy
  • Sig Match Ballistic Alloy
  • Firing behavior
  • Cocking effort
  • Trigger pull
  • Summary

Today we look at the velocity of the new Umarex Trevox air pistol. I said in Part 1 that this is a pistol to watch, so consider today’s report watching!

RWS Hobby

First up will be the RWS Hobby pellet. I’m going to show you more than just the average velocity today, because there is something more to learn from this test. Let’s look at the first 4 shots.

Shot………..Velocity
1……………..708
2……………..665
3……………..656
4……………..617

The Trevox started out dieseling strongly, like so many spring guns do when they are new. Veteran airgunners are used to this, but it may surprise a newcomer to the hobby. Let’s resume this string at shot 5. read more

  • Popeye?
  • What’s next?
  • Summary

Time for me to bend the bow of Ulysses and see what it can do. Today I have a slightly different accuracy test for you.

The test

I tested the rifle at both 10 meters and 25 yards. I shot 5-shot groups today because this rifle is just too hard for me to cock. A tired BB is a sloppy BB. All shooting was off a sandbag rest in the normal fashion and I used the artillery hold, both because I knew the rifle would be twitchy, something several readers confirmed.

Sight-in

Sight-in took five shots. As it came from the package the rifle was shooting high and right. The open sights have scales to tell you where they are and I found the windage scale most helpful, getting on target. read more
