WARNING: This conversion changes the operation of the pistol to use air at up to three times the pressure it was designed for. The parts that are installed are strong, but there are other parts in the gun that aren’t changed and could fail when subjected to the higher pressures. Pyramyd Air advises anyone making such a conversion to exercise extreme caution.

Tech Force TF90 dot sight

Tech Force TF90 dot sight

This report covers:

• Tech Force TF90 dot sight
• Description
• How does a dot sight work?
• Parallax?
• Easier to use than open sights
• Not the latest and greatest

Tech Force TF90 dot sight
I was right there when this Tech Force TF90 dot sight was being designed. I watched it evolve over several years of development, as each new model was revealed at successive SHOT Shows. I even tested a forerunner of this sight in the 1990s for The Airgun Letter by mounting it on a Beeman P1 pistol.

The Tech Force TF90 was developed by Compasseco, who used a Chinese optics factory that also made sights for their military. According to Duane Sorenson of Compasseco, the optics and manufacturing details of this sight were superior to similar Chinese-made dot sights because of who built it. In the 1990s Compasseco did a lot of business in China and had enough influence to get products designed to their specifications, and Duane was especially proud of this sight.

Leapers UTG Accushot 2-7X44 Scout scope: Part 4

This blog post was mistakenly published a day early, and we got some comments to it before we discovered that. So, for those of you who try to be the first to make a comment, it looks like you’ve missed your turn!

UTG 2-7X44 Scout SWAT scope
Leapers UTG Accushot 2-7X44 Scout scope is a remarkable sight!

This report covers:

• Scout scope on centerfire rifle
• My Mosin Nagant
• A powerful round
• What today’s test is all about
• What about the scope?
• The mount
• Overall evaluation

Scout scope on centerfire rifle
This is a special report I promised several readers who are interested in this UTG 2-7X44 Scout SWAT scope. When I tested it on an airgun, I used the Crosman MK-177 Tactical multi-pump pneumatic because it allowed me to mount the scope out away from the eye. That was a good test, but it was also a forced one because I could have mounted any scope on that airgun. Scout scopes are made for those troublesome arms that don’t allow the mounting of scopes in the conventional way. I asked Leapers to send me a mount for my Mosin Nagant 91/30 rifle — a centerfire rifle that needs a scout scope because of its straight bolt handle. While the bolt handle can be bent down to clear the scope, the scout scope is a non-gunsmithing solution that allows you to preserve the rifle in its original condition. Not that any Mosin Nagant in existence today is still in its original condition!

Parts 1 and 2

Ruger Air Hawk velocity retest
I hadn’t planned to do this test, but the velocity numbers in the previous blog post were so far off expectations that I felt compelled to try it, again. I was curious about the poor velocity performance of the Ruger Air Hawk combo. Someone suggested the breech seal might be too low and others agreed, so I shimmed the seal. It appears to be ever so slight higher now, but the velocity is definitely higher.

Hatsan AT44-10 Long QE: Part 5

Hatsan AT44S-10 Long QE
Hatsan’s AT44S-10 Long QE is packed with features for airgun hunters.

This report covers:

• Inconsistent shots?
• Most accurate pellet?
• 100 yards means scope adjustments
• JSB Exact Jumbo heavy pellets
• Crosman Premier pellets
• H&N Baracuda Green pellets
• Gamo Hunter pellets
• Call it a day
• Conclusions
• Pyramyd Air sale

Today is a test of the Hatsan AT44-10 Long QE at 100 yards. I don’t do this very often for many reasons; but when I find a PCP that’s exceptionally accurate at 50 yards, I feel it’s worth testing at the greater distance. It takes a perfect day for this test because any wind will push the pellet around. We don’t get many windless days here in Texas, but this past Wednesday was one of them. It was so calm that dandelion fuzz would fall straight down.

Man-powered Weapons and Ammunition: A review

by Tom Gaylord, a.k.a. B.B. Pelletier

book cover
This is the softcover version of the book.

This report covers:

• When is 12 foot-pounds more than 12 foot-pounds?
• How long is long enough?
• Ka-boom!
• Hodges catapult gun
• Why do airguns lose so much power?
• What kind of power can I expect?

This is a brief book review of The Practical Guide to Man-powered Weapons and Ammunition by Richard Middleton, copyright ©2005, published by Skyhorse Publishing, New York. Dennis Quackenbush sent this book to me just because he thought I needed to read it. Well, I’ve read it and now I’m recommending it to all of you.

The subtitle is Experiments with Catapults, Musketballs, Stonebows, Blowpipes, Big Airguns, and Bullet Bows. That should give you an idea of what’s included. Mr. Middleton explains dozens of different experiments in which he advances his understanding of pneumatic and spring-operated projectile launchers. He calls them weapons, as is the custom in the UK and also Australia, where he’s from. Here in the U.S., we define weapons as things meant to injure or kill; and, while most of what is in his book will do exactly that, our American culture sets the word weapon apart as a term charged with emotion. Most of us don’t consider airguns to be weapons.

This report covers:

• Accuracy testing
• RWS Hobby pellets
• Trigger control
• Shot cycle
• Gamo Match pellets
• Gamo Raptor PBA pellets
• Air Arms Falcon pellets
• What’s the verdict?

Let’s look at the accuracy of the Gamo P900 IGT air pistol. Several of you have wondered if this is the air pistol you’ve been waiting for — today, we’ll see.

Accuracy testing
I shot the pistol off a rest at 10 meters. I rested my hands on a sandbag and held the pistol away from the bag with a two-hand hold. I used a 6 o’clock hold sight picture, which is more difficult to do with a bead fiberoptic front sight. But the target was brightly lit, and the firing point was in the dark; so, the fiberoptics did not illuminate, nor did the strange yellow rear sight blade cause any problems.
