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

Things are back on track today and we will look at the accuracy of the Umarex Legends Ace in the Hole revolver. I hope it’s good!

The test

I shot from a sandbag rest at 10 meters. Ten meters is far for an action pistol, but I am trying to establish where the Ace is, in terms of hitting the target.

I wore my reading glasses so the sights would appear sharp. Single action sights work a little differently than any other revolver sights, because the rear sight is a notch in the back of the frame. The sides of this notch slope up toward the notch on both sides and I find myself holding the front sight blade a little higher than I am used to. Once I get the sight picture, though, I can do good work with an SAA. 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


Beeman R9 with Vortek center-latching air piston: Part 3

This report covers:

  • Adjust the pressure
  • Filling
  • R9 disassembly and assembly
  • JSB Exact
  • Predator Polymag
  • H&N Field Target Trophy
  • H&N Baracuda
  • Crosman Premier
  • Benjamin Cylindrical
  • Discussion
  • Trigger
  • Cocking effort
  • Evaluation

Today we look at adjusting the Vortek Center Latching Air Piston, which I refer to as the center-latching unit (CLU). It went faster and easier than I imagined.

Adjust the pressure

To adjust the air pressure in the unit I had to disassemble the Beeman R9, to get the unit out. That procedure is described in Part 1. Once the unit is out, the piston seal has to be removed to reveal the air port.

Beeman R9 CLU port
Looking down into the fill port of the CLU we can see the ball valve.

To adjust the pressure in the CLU, first release all the air. That way you start from zero. The unit fills very fast from a hand pump and this is the best way to ensure accuracy. read more

  • 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

  • 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

A surprise is coming

It’s very fitting that I announce today that I have a surprise coming for you readers. The surprise is a multi-pump, as well, and it will be presented in the historical section. I have some other reports to get through before I can get to it, but this is a surprise worth waiting for!

Ugly step-sister

You readers were really hard on the Umarex Strike Point multi-pump pistol when I introduced it in Part 1. You made fun of its looks, the trigger, the weight and everything else. Today we find out about the velocity.

Oil a multi-pump

Multi-pump pneumatics need to be oiled to obtain their best performance. The Strike Point I’m testing came to me well-oiled, but I added some Crosman Pellgunoil to that. Let me show you how a multi-pump should look. read more
