Today was day of learning, or perhaps I should say remembering, because today’s test of the Chinese B3 underlever took me back to my early days with spring-piston air rifles. I will explain as the report unfolds.

Refresher

I found this tired old air rifle in a pawn shop many months ago. In this series I have replaced the breech seal with a faucet washer, opened up the powerplant, lubricated the moving parts with Tune in a Tube and shot the rifle for accuracy. That was when I discovered how accurate this old Chinese underlever is. So I vowed to shoot it for accuracy once more, now that the powerplant has been tamed. 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

A history of airguns

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

  • Oil a multi-pump
  • Test 1. Velocity per pump
  • Learned a lot!
  • Curiosity
  • Pump force
  • Test 2.

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


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

  • Interest
  • CO2 cartridge
  • RWS Hobby
  • Air Arms Falcon
  • Sig Match Ballistic Alloy
  • Shot count
  • Trigger pull
  • Evaluation

Today we look at the velocity of the Umarex Legends Ace in the Hole revolver. The specs say 340 f.p.s., but today we’re going to find out for sure.

Interest

There is a lot of interest in this sawed-off Colt. Many of you readers either have one already or are wanting to get one. Let’s see how they work.

CO2 cartridge

First I installed a fresh CO2 cartridge. The captive Allen wrench in the left grip panel made installation a breeze, but don’t forget to put a drop of Crosman Pellgunoil on the tip before you install it. The oil gets blown through the valve by the gas and gets on all the inner seals. The cartridge pierced and sealed in less than a second. Turn the piercing screw one more turn after piercing, but then stop. That will ensure sealing, while not compressing the face seal too much. read more

  • Why hard to scope?
  • Stock extension
  • The test
  • Sight in
  • Air Arms Falcon pellets
  • Sig Match Ballistic Alloy
  • Journey pellets
  • Discussion

Today I will finish the report of the Embark air rifle from Umarex. This is the rifle that’s used in the Student Air Rifle (SAR) program. I tested it for accuracy at 25 yards with open sights last time. Today I will scope it.

Why hard to scope?

The Embark has a small-diameter spring tube, with the scope base dovetails cut directly into the tube. That means there is a high crown between the dovetails that many scope mounts will bottom out on. Their jaws will not be able to reach the dovetails on the rifle because of this. But I knew that BKL mounted would work, because it has nothing that gets in the way of that high crown. I selected BKL 263 MB 2-piece scope rings to attach the UTG 3-12X32 AO Bug Buster scope. I had planned to use a 3-9 power Bug Buster, but the 3-12 came to market in time for today’s test. read more
