Part 3

This report covers:

  • Hold?
  • Stock screw torque
  • Scope zero
  • Crux seated deep
  • Crux seated flush
  • JSB Exact Jumbo
  • 25 yards
  • DUH!
  • Last pellet
  • Where are we?
  • What’s next?
  • Summary

Today will be the start of the Sig ASP20 accuracy test, but it will be different than all the other rifles I have tested. I usually mount a scope and begin testing at 10 meters — looking for one or more pellets that are accurate for tests at longer ranges. I’m not doing that today. Before I get into the report, though, I want to address some readers’ concerns.

Hold?

Someone asked me to check the sensitivity of the rifle to how it’s held. But I already reported on that back in August. I discovered back then that this rifle likes to rest directly on the sandbag and not be held by the artillery hold. I will test the artillery hold in later installments, but it’s pretty much a given that this rifle likes to be rested right on the bag. read more


How the Price-Point PCP (PPP) has changed the face of the airgun world

by Tom Gaylord

Gauntlet
Umarex’s Gauntlet was the first PPP to be announced, but several others beat it to the marketplace.

This report covers:

  • Gauntlet dropped!
  • For Hank
  • For the manufacturers
  • What is a PPP?
  • Cost
  • Required features
  • Nice features to have
  • Caliber
  • ALL BOATS ARE FLOATED!
  • Compressors
  • Other PCPs
  • Sig
  • AirForce Airguns
  • On and on
  • Summary

Gauntlet dropped!

When Umarex announced the new Gauntlet air rifle the savvy airgunning world was stunned. A precharged pneumatic (PCP) that was a repeater, was shrouded with an active silencer, had an adjustable trigger and stock, was accurate and came with a regulator — all for less than $300. They named it appropriately, because it was a huge gauntlet to drop on the airgun community. I’m sure this is exactly what Umarex had in mind, though the particulars of how it has and still is unfolding I’m sure have been as much of a surprise to them as they have been to others. read more

This report covers:

  • Trigger adjustment
  • Whiskey3 4-12X44 scope
  • Today’s test
  • Velocity with the lead Crux Pb
  • JSB Exact Jumbo
  • JSB Exact Jumbo Heavy
  • How fast will she go?
  • Easy cocking!
  • Barrel loose when cocked
  • Trigger pull
  • First stage?
  • Summary

Today we will find out about the velocity of the .22-caliber Sig ASP20 breakbarrel rifle that I’m testing. Before we get into that, though, I have a couple things to address.

Trigger adjustment

First, reader Siraniko asked this:

“You will have to show us a picture how the trigger is adjusted while in the gun. The only picture I could find of how to adjust the trigger showed it while separated from the gun (https://www.pyramydair.com/blog/2018/08/my-day-at-sig-sauer-part-2/).”

That’s a good question. He asked because I showed the bent Phillips screwdriver that’s used to adjust the trigger pull weight. So let’s discuss the trigger adjustments now. read more


Piston seals: Part 2

by Tom Gaylord
Writing as B.B. Pelletier

Part 1

This report covers:

  • Importance of round air chambers
  • My best advice
  • Out of round pistons
  • The deal
  • Plain seals
  • Leather piston seal assemblies
  • Parachute seals
  • The PTFE seal
  • Last subject — seal materials
  • Piston rings
  • Summary

Today we will continue our discussion of the piston seal. This report was prompted by the comments of new reader Arvizu, who said, “ I noticed, too, that the seal plays an important role to define performance (sometimes small variations in diameter makes the difference). I would like to clarify that this is only my appreciation and limited experience with airguns.”

In Part One I attempted to show how a piston does its job. Arvizu’s question seemed to imply that he thought there might be an unlimited horizon for the piston seal, if only the technology could extract it. I tried to show that a piston is limited by the volume of air it compresses and improving piston seals is asymptotic. In other words there is a limit on the power that’s possible and we are now shaving small percentages as we approach that limit. To put it bluntly, we will never see the power of a spring piston system doubled by the seal. Never! read more


Umarex Trevox air pistol: Part 3

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


2018 Pyramyd Air Cup: Part 1

by Tom Gaylord
Writing as B.B. Pelletier

Field Target meeting
A record 104 shooters receive their orientation briefing from Tyler Patner on the first day of the field target match.

This report covers:

  • The vendors – H&N
  • The vendors – Leapers
  • Public range
  • Gauntlet and Fortitude
  • Sig ASP20
  • More interesting airguns to come
  • Field target
  • Pistol match cancelled
  • World-class airguns
  • More to come

The Pyramyd Air Cup is a public event that combines airgun competitions, a public range, a chance to meet many of the vendors who make the airguns and accessories you read about and, most importantly, a chance to shoot airguns you have seen and heard about but could never try. A day at this event is worth a year of reading on the internet — this blog included.

The Cup was held at the Tusco Rifle Club in Midvale, Ohio, which is about midway between Cleveland and Columbus. It’s convenient to people living in a 500-mile radius, and this year I saw people from all over the U.S., including Florida, California and Hawaii. People had come from Canada and the UK, as well. The H&N general manager, Florian Schwartz, was there, and Tobias Schmidt represented Diana. Both men had come from Germany to be there. 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
