Part 1
Part 2

This report covers:

    • Power adjustment
    • Striker (hammer) blow
    • Understand?
    • Transfer port control
    • Michael — this is for you
    • Stability
    • Finally — how practical is adjusting power?
    • Summary

    Today I will try to finish my answer to Michael about power adjusters on precharged pneumatics (PCP), which I have broadened to include air regulators. Please read Parts 1 and 2 to see what has gone before.

    Power adjustment

    Michael, there are several things an owner can do to adjust the power of his PCP. A longer barrel will often increase power, but that’s not immediately within the owner’s grasp. We are talking about adjusting power of a specific gun by means of things that are easy to do, without changing or modifying the rifle.

    Striker (hammer) blow

    Power can be adjusted easily by controlling the striker blow to the firing valve. A harder blow will force the valve open wider or for a slightly longer time. Either one of those or both of them means that more compressed air can flow out of the reservoir to power the pellet. As long as the pellet is inside the barrel, the more compressed air that gets behind it to push it, the faster it will go. read more


SHOT Show 2018: Part 5

This report covers:

  • Meopta
  • Leapers
  • P.O.I. Airgun Rings
  • Vanquish 700
  • Air Venturi Hellboy
  • ASG
  • AirForce
  • Are we done?

Before I start I want to say a word about who I cover at SHOT. There are plenty of airguns I never look at, for reasons I think are good. These are the fringe companies that have no representation in the U.S., or they have a couple of shyster dealers with bad reputations. I don’t want to give them any attention. The other people covering the show can “scoop” me on these. Yes, I miss a few things, but I also avoid giving credibility to guns that will only break your hearts.

That said, why do I cover Leapers and not other scope companies? Am I getting a kickback? Well, there is a story here. I used to go to Burris, Leupold and many other scope manufacturers, and they all received me the same way. “Airguns? You write about airguns? Sure, we have a couple scopes that could be used on an airgun, I guess.” read more


The development of the .22 rimfire cartridge: Part 3

Part 1
Part 2

A history of airguns

This report covers:

  • .22 WRF
  • Not a magnum
  • The .22 Winchester Automatic
  • Corrosive priming
  • High speed
  • Splatter-Less
  • Summary

We are back with the .22 rimfire cartridge. We left it in the 1890s, as smokeless powder was just starting to be introduced. I will talk about that in a moment, but I want to start with another cartridge that lasted for quite a while but is obsolete today — the .22 Winchester Rimfire, or .22 WRF.

.22 WRF

This cartridge was introduced with the Winchester 1890 slide-action rifle that was also called a pump gun. I have owned 2 1890s in this caliber, and in the 1960s I thought this cartridge was the bee’s knees! It uses a 45-grain flat-nosed lead bullet that is not heeled like the .22 Long Rifle bullet. The diameter of the bullet is 0.224, so it’s also larger (.22 LR bullet is 0.2225”-0.223”). The barrel twist was increased to 1:14” to stabilize the heavier bullet. read more

This report covers:

  • The big news
  • Benjamin Fortitude
  • Marauder Field and Target
  • Akura
  • Traveler
  • SigASP20
  • Tight breech and no droop
  • The trigger
  • AirForce E-Pump

I will start the third day on the SHOT Show floor with Crosman. They always have loads of new products and this year was no exception. I actually had to visit the booth two separate times to get what I am about to tell you.

The big news

So — what’s the big news at Crosman? I guess that depends on what interests you, but since I am defining this year’s show as the battle of the price-point PCPs (precharged pneumatic rifles with upscale features selling for under $300), let’s start with the Fortitude.

Benjamin Fortitude

Benjamin’s new Fortitude PCP is regulated, a repeater and has a shroud. It is positioned between the Discovery and the Marauder. read more

Part 2

This report covers:

  • Gamo
  • Big bores?
  • Daisy
  • Gamo Urban
  • Winchester big bores
  • Diana
  • Umarex USA
  • Cowboy Lever Action
  • Single action
  • But wait…
  • And the show goes on…

We’re back at it today. I’ll start with Gamo

Gamo

Gamo is the one company that never gives me any information about their products. A few years ago their VP of sales was very helpful, but in the last 20 years of attending the SHOT Show, that was the only time anyone helped me. So I just read the signs and try to make sense of it.

Big bores?

Gamo has a line of big bore airguns this year. They look like Bizarro copies of AirForce guns — where the size and shape are similar but nothing is quite the same. These single shots are called the TC 35 and TC 45, indicating their calibers. They have carbon fiber air reservoirs that serve as the butt of the rifle. read more

Part 1

This report covers:

  • AirForce Airguns
  • What’s next?
  • Hatsan USA
  • Hercules Bully
  • Price point Hatsan
  • Sortie Tact
  • Air Venturi
  • A new IZH 61?
  • Multi-pump
  • One last thing!

Here we go! I go to these shows thinking that nothing can get me excited anymore, and that ends at the first booth, Today that happened before the show opened. AirForce Airguns has been keeping a secret for many weeks that they promised to reveal just before the doors opened.

AirForce Airguns

A few minutes before the doors opened, AirForce revealed that they are incorporating the Theoben Rapid line of PCPs into their lineup. Formerly known as Rapid Air Weapons (RAW), the Rapid lineup is on the cutting edge of pneumatic quality. The only drawback they have is the long wait time when an order is placed. AirForce will bring their manufacturing prowess to bear on shortening the lead time between ordering and shipping, while maintaining the high level of quality the brand has become known for. read more


Media Day at the Range — SHOT Show 2018: Part 1

by Tom Gaylord
Writing as B.B. Pelletier

Media Day upper
The upper range at Media Day has about 50 ranges and vendors. Because of crossbows, the ranges go in both directions.

Media Day
On the lower range there are more ranges, also going both directions, with shotguns on the right.

This report covers:

  • SHOT Show
  • A great find!
  • My interest
  • My collection
  • This BB gun
  • Cocking
  • Takedown
  • Number 25?
  • Sights
  • Summary

Media Day at the Range is an event for gun writers and video makers, only. About 2,000 of us are taken to the Boulder City range where we are allowed to shoot and use some of the newest guns and accessories.

Umarex Hammer

We waited all last year for the Umarex Hammer to come out. From what I saw and sampled this year, I think we will see production guns by mid-2018.

The Hammer is a repeating .50-caliber big bore that gets 4 powerful shots on a fill ton 4,500 psi. The regulator drops the firing pressure to 3,000 psi, and the first 3 shots are all at the same pressure. Shot 4 drops below 3,000 slightly, but at 40 yards all the bullets should stay in a tight group. read more
