  • Final assembly — the stock
  • The barrel
  • Off to the range
  • Shooting sensation
  • Cocking effort
  • Accuracy
  • Whisky 3 ASP 4-12X44 scope
  • Summary

Boy, is there a LOT of interest in this new rifle! You guys are asking a lot of very good questions about the new ASP20 breakbarrel rifle, as you should. I will begin by addressing some of the most prominent ones.

Why a gas spring?

Some call it a gas piston, others say gas ram, but we are all referring to the gas spring (the industry term for a spring that uses compressed gas in place of a coiled steel spring to do its job). Gas springs replace coiled steel mainsprings in spring-piston airguns. They are more modern and easier to make and obtain, they don’t take a set if left compressed, they are less susceptible to cold and, if the design is right, they are smoother operating. They also eliminate several parts that rattle and they remove some weight from the powerplant. read more

A history of airguns

This report covers:

  • Adjustable trigger!
  • Trigger-pull
  • Courage arrives!
  • Safety
  • Adjust the bolt handle position
  • Velocity
  • Test 1.
  • Test 2.
  • Test 3.
  • Pump effort
  • Summary

We’re back at it with the Sheridan Supergrade today. I will get to the velocity testing, but there are still a couple more surprises before that.

Adjustable trigger!

That’s right; the Sheridan Supergrade came with an adjustable trigger! Imagine that — an airgun from the 1940s with a trigger that adjusts.

The trigger adjusted in a unique way — by changing the location of the sear spring on a notched bar. To do this the rifle has to be out of the stock, which is not as straightforward as it is with some guns, so I won’t do it today. But I may work up the courage to try it at some point in our test. read more


Revitalizing a Benjamin 392: Part 3

  • JSB Exact Jumbo Heavys
  • H&N Baracuda Match
  • Well?
  • JSB second test
  • Evaluation
  • Summary

Today is accuracy day for the Benjamin 392 that’s been rebuilt. What you are about to see is stunning! This report will blow your minds!

The test

I looked at the results of the Part 2 velocity test and determined that 4 pumps would be a good number for all pellets. Since this is a multi-pump where each shot takes more time, I decided to shoot 5-shot groups, to see whether one pellet is more accurate that the rest. If I found one, I would then shoot 10 shots with that one at a fresh target. That led to an extremely rare occurrence that’s going to surprise most of you. read more

Today we look at the Benjamin 392 that has been resealed. The first report was done on the gun as it came from the pawn shop. All I did was oil the pump head with ATF Sealant and then test the gun. It’s been a long time since Part 1, so you may want to read it again. In the last test I said this was the fastest 392 I have ever tested.

The rifle responded well to ATF Sealant. I will run those number with today’s test figures for comparison.

The rebuild

I sent the gun to reader Jeff Cloud for a rebuild. He is the guy who rebuilt my Sheridan Blue Streak a couple years ago. read more


Gamo’s Urban precharged air rifle: Part 3

This report covers:

  • Scoped
  • The test
  • Sight-in
  • JSB Exact Jumbo
  • Air Arms Diabolo Field
  • H&N Baracuda Match
  • Other pellets
  • Experience
  • What next?
  • Summary

Today we start our look at the accuracy of Gamo’s Urban PCP. Fasten your seatbelts, guys, because today will be a bumpy ride!

Scoped

I mounted a 4-16X50 Leapers scope that is obsolete, and is unlike any scope they make today. But 4-16 power is the key.

Knowing the Urban’s performance curve, I filled to 3000 psi and shot 20 shots before refilling. There are 25 available at this pressure, but I was shooting 10-shot groups, so 20 was the limit.

The test

I shot the Urban off a sandbag rest with the rear of the butt rested for extra stability. The range was 25 yards.

Sight-in

The first shot hit the target from 12 feet about 1.5 inches below the aim point, and centered on the target, so I moved back to 25 yards and resumed sight-in. In 5 shots the rifle was zeroed, and I sighted the first pellet a little high to preserve my aim point. read more


Crosman 2400KT CO2 Air Rifle – Part 10

Today we have something special. This is Part 10 of an ongoing guest blog from reader Hiveseeker, but his report today is so big that I had to break it onto two parts. The second part of this report will run tomorrow as Part 11. He continues to research this subject that fascinates both him and many other readers.

This is about the Crosman air rifle he really enjoys. If you’d like to write a guest post for this blog, please email me. Now, over to you, Hiveseeker.

  • Scope performance
  • H&N Baracuda with 5.50mm head
  • Scope adjustment
  • Group two
  • Group three
  • Evaluation
  • Group four
  • Group five
  • Summary

Today I take the Hatsan Bullmaster out to the 50-yard range. I might have said in the past that I would attach a bipod for this test, but instead I rested the rifle on a sandbag.

I shot the BullMaster off a sandbag rest.

The test

It is important to remember that the BullMaster is a semiautomatic. However, it is also a repeating pellet rifle. It doesn’t handle the pellets the way cartridges are handled in semiautomatic firearms, so that’s one accuracy-killer that can be discounted. It feeds from a circular magazine. The bolt that pushes the pellet into the breech is operated by air instead of manually by a bolt. Therefore we can expect airgun repeater-level accuracy. read more
