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

Today’s report came to me as I was planning to test the accuracy of the Umarex Legends Ace in the Hole revolver. I have so many tests waiting for my time, but today’s report had to come first.

Gentlemen — we are living in airgunning’s Golden Age. I know I have written that many times, but today I would like to reflect on all the good things that are happening in our world. Let me start with the Price-Point PCP.

Price-Point PCP

When I got into precharged pneumatics in 1995, I was dragged into it kicking and screaming. No PCP rifle cost less than $600 in that day (think $900 today) and the high-pressure hand pump had just been invented. I had to use a 3000 psi aluminum scuba tank that cost an additional $120 and I had to beg the local dive shop to fill it for me. I actually created a release form that I signed and left on file with them to absolve them from all risk of selling air to a non dive-certificated person! That might sound extreme in 2018, but in 1995 that was the way it was done, and plenty of dive shops refused to sell us air. read more

This report covers:

  • Pre-work baseline
  • RWS Hobby
  • Harsh firing cycle
  • Rifle is breaking in
  • Air Arms Falcon
  • Sig Match Ballistic Alloy
  • RWS Hobby again
  • Discussion
  • Cocking effort
  • Trigger pull
  • Summary

Today I will test the velocity of the B3 underlever that we cleaned and lubed on Friday. This will be a fantastic learning lesson for all airgunners, because the results are most informative!

Pre-work baseline

If you have been following this report you know I discovered in Part 2 that the rifle wasn’t performing to expectations. In Part 3 I replaced the breech seal and tested the velocity. That gave us a baseline we can use today for a before and after comparison. Let me get to the tests right now.

RWS Hobby

The first pellet to be tested was the RWS Hobby. In Part 3 Hobbys gave an average 617 f.p.s. with a 24 f.p.s. spread. read more

This report covers:

  • Compression chamber and piston out
  • Cleaning

  • Lubrication
  • Does it work?

  • Summary

Today I take the Chinese B3 underlever rifle apart and we see inside. This will be a good one.

Remove the stock

The first step is to remove the stock. That’s two forearm screws and one in the triggerguard. Once out, I could see this rifle is very rusty. It’s so rusty that it will take many hours to clean. I don’t have that kind of time so I’m going to clean only what needs to be cleaned.

B3 action
With the action out of the stock you can see rust everywhere! Notice the flat bar in front of the trigger housing. That’s the anti-beartrap. read more


Beeman R9 with Vortek center-latching air piston: Part 2

Part 1

This report covers:

  • Today’s fill
  • JSB Exact
  • Predator Polymag
  • H&N Field Target Trophy
  • H&N Baracuda
  • Crosman Premiers
  • Benjamin Cylindricals
  • Cocking effort
  • Trigger pull
  • Firing behavior
  • Summary

Today is velocity day for the Beeman R9 with the Vortek center-latching gas piston that I’m calling the center latching unit (CLU). Bear in mind as you read today’s test, that this unit allows the owner to adjust the pressure inside the gas piston — raising or lowering the velocity and cocking effort. So, this is the first of several tests of the unit.

Today’s fill

I filled the CLU to 675 psi when I installed it. So that’s how it’s set up today. I will test it with 6 different .20 caliber pellets — one more than Pyramyd Air carries, if you don’t count the felt Beeman cleaning pellets. Let’s get started. read more


The world’s best airgun doesn’t exist…

A history of airguns

This report covers:

  • The start
  • The deal
  • The challenge
  • It is achievable
  • The Marauder
  • Good points
  • Bad points
  • Bronco
  • The world’s best air rifle
  • Synthetic stock
  • The deal
  • History?

…but it has in the past. Or parts of it have existed. They are very rare today, but at one time there were many airguns that were 80 percent of the way to being great.

The start

This report started this past Wednesday in an archery store. Next week I will mention why I was in the store, but here’s what happened. The older man behind the counter, after learning what I did for a living, asked me what would be a good airgun for him to get. I stood there like a deer in the headlights, running through a half-century of experience and trying to boil it down to one sentence, when he added, “…and be able to take out a squirrel once in awhile.” 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
