Ruger 10/22.

This report covers:

  • Mounting the dot sight
  • The R47 sight
  • Can you see the front sight through the dot sight?
  • Sight-in
  • The test
  • First group
  • RWS Superdome
  • Crosman Premier Light
  • Sig Match Ballistic Alloy
  • Ten-shot group
  • Discussion
  • Summary

Today I will test the Ruger 10/22 at 25 yards. I’m doing this so the rifle can go back to Umarex, because they are apparently waiting for it. Other writers, I suppose.

Mounting the dot sight

As I mentioned in Part 2, Umarex sent an Axeon R47 dot sight to test on the Ruger, and today I will mount it and sight it in, then test the rifle at 25 yards. To mount any aftermarket sight to a 10/22 you have to first install Weaver bases. I showed you the factory-drilled holes for those bases in Part 2. I took a new package of two-piece Weaver bases and screwed them to the top of the receiver. That took 5 minutes. read more

This report covers:

  • Setup
  • Pellets selected
  • The test
  • JSB Exact Heavy
  • Cocking and trigger
  • Discharge sound
  • Air Arms Falcons
  • Crosman Premier light
  • Discussion
  • Summary

We start accuracy testing the Benjamin Fortitude today. Sometimes I begin this test at 10 meters and other times at 25 yards. I’m starting at 10 meters today because the Fortitude is a significant precharged air rifle that I want to test very thoroughly.

Setup

I mounted a vintage UTG 8-32X56 SWAT scope on the rifle. The scope was so old it only parallax adjusted down to 25 yards, so I ran it at 8 power for this test. The bull was a little blurry but easy enough to see. When I get back to 25 yards the image should be crystal clear. read more

This report covers:

  • Second rifle
  • Crosman Premier lites
  • JSB Exact Heavy
  • Trigger
  • Air Arms Falcons
  • Premier lites again
  • Shot count
  • Discharge sound
  • Test target
  • Evaluation

Today we resume our look at the Benjamin Fortitude precharged air rifle. I will summarize where we have been, so folks reading this report for the first time will understand what is happening.

Second rifle

This is the second Fortitude I have tested. Parts 1 and 2 of this report belong to the first rifle. The first rifle’s inlet valve locked up at the end of the velocity test and remained open when I bled the air after the fill. The entire gun exhausted all its air. I tried to fill it several times, just to be sure. So I stopped the test at that point and requested a replacement rifle in the same .177 caliber. While this is Part 3, I will actually run another velocity test today, since this is a brand new airgun. read more

This report covers:

  • Point one
  • Crosman Premier lites
  • JSB Exact Heavy
  • Why such a large velocity spread?
  • Air Arms Falcons
  • RWS Superdomes
  • Shot count
  • Cocking effort
  • Trigger pull
  • Inlet valve failed
  • Evaluation so far

Today we look at the velocity of the Benjamin Fortitude. As this is one of the new price point PCPs, this test should be interesting.

Point one

My test rifle leaked down from the initial fill in three hours. I had filled it to 3,000 psi, then set it aside to do other work. When I returned three hours later nearly all the air had leaked out. However when I refilled it, I couldn’t hear a leak. It was apparently slow enough to allow testing, so I proceeded.

Crosman Premier lites

The first pellet I tested was the Crosman Premier 7.9-grain dome. They averaged 885 f.p.s. over 10 shots. The low was 872 and the high was 900 f.p.s. That’s an 18 f.p.s. spread. At the average velocity this pellet produced 13.74 foot pounds of energy at the muzzle. read more


The Stiga Zenit – an EM-GE Zenit clone: Part 2

Part 1

A history of airguns

Today’s report is the completion of a guest blog from reader Paul that began last Friday. He is telling us about his Stiga Zenit — an airgun not many have heard of.

If you’d like to write a guest post for this blog, please email me.

This report covers:

  • Firing behavior
  • Power
  • Accuracy
  • Wrapping it up

Okay, Paul, finish what you started.

On Friday I showed you the basic construction of my Swedish Stiga Zenit pistol that closely copies the EM GE Zenit made in Germany. Today we will look at its performance.

When the cocking lever is first pulled upwards the spring loaded barrel will also tilt up about 15 degrees; this makes it simple to inspect or clean the barrel from the rear and also serves as a sort of “safe mode”. Swinging the lever through its arc completes the cocking action and requires about fifteen pounds of effort. read more

  • Qiang Yuan Training pellets
  • Additional testing
  • Discussion
  • Summary

Today we look at the accuracy of the Benjamin Trail Nitro Piston Mark II with the factory-mounted open sights. But before we get to that, there is some old business to clear up.

Adjustable trigger

There was quite a bit of interest in the adjustable trigger last time — mostly because I showed that I could not get a screwdriver on it to adjust. There was so much interest that I vowed to try to adjust it for this report.

I removed the barreled action from the stock. All it took was removing the 4 stock screws and lifting the action out of the grip/stock. The safety button fell out at the same time. read more

The detent and how I open the gun

I’ll start today’s report by answering reader Siraniko’s questions from the last post. He asked me to show the locking detent and how I manage to open the gun for cocking. Here’s the detent.

Benjamin Trail detent
The chisel detent is long and narrow. It’s not under that much spring tension, so it opens easily, but the shallow angle of the slope ensures that it locks the beech securely.

That detent chisel face is long and shallow but the spring is not that strong. I can push it in with my finger. So the long shallow slope of the chisel on the detent is what’s keeping the breech locked so tight. read more
