Good things happen

Sometimes everything works as it should. No, even better, things sometimes work like you think they are supposed to. Today’s report is such a day.

This report is now 11 parts long, so I will summarize. I’m testing a Beeman P1 pistol that someone traded to me at an airgun show. He included the parts I needed for a rebuild, so I did that for you in Parts 4 and 5. Then I tested it for accuracy again in Parts 6 through 9.

In Part 10 I introduced you to the UTG RDM20 Reflex Micro Dot sight that Pyramyd Air doesn’t currently carry — but they had better do so! Because I am about to show you a dot sight that was made for the Beeman P1! read more


The way of airguns

This report covers:

  • What makes an airgun good?
  • A few good airguns — rifles
  • Challenger and Edge
  • A few good airguns — air pistols
  • Beeman P17
  • Summary

I’m writing this on Christmas Day and don’t want to do another test today. I thought about airguns this morning and came up with some interesting thoughts.

What makes an airgun good?

I used to think accuracy was the only requirement for an airgun to be good but now I realize it’s so much more.

A few good airguns — rifles

Going back a couple years, I was able to purchase a Beeman R10/HW85 that Bryan Enoch had tuned. I had seen and shot that air rifle several years earlier, at the Arkansas airgun show in Malvern. After just a few shots I gave Bryan one of those, “If you ever want to sell this…” requests. To my surprise, this one paid off. I was able to buy it at the 2017 Texas Airgun Show. read more

  • Summary

Merry Christmas, everyone. I am working on tomorrow’s blog today, so, yes, there will be one. Today’s report will be shorter, but it’s to the point.

Cleaning the rifle

Today I will talk about cleaning the barrel of the Sig ASP20 breakbarrel rifle. When Ed Schultz of Sig said that some of their new air rifles respond to having their barrels cleaned lightly, the jungle drums started to beat aloud — “But it has a silencer! The cleaning patch will get lost in the baffles!”

What baffles?

And, just that quick, I have finished this report. Because, like many other airgun silencers, the ASP20 silencer has no baffles. NO BAFFLES! So, there is nothing to grab your cleaning patch. read more

This report covers:

  • Tractors
  • Hierarchy of removing a stuck piston seal screw
  • Time to move on
  • Remove rust
  • What’s next?
  • Have to make a breech seal
  • How to make the seal
  • Summary

This is a continuation of the report on overhauling reader Michael’s Winchester 427 that is a Diana 27. Today I’m showing you the details of working on a spring gun.

The piston seal

When Diana chose a threaded screw to attach the piston seal to the piston body, they couldn’t have selected a worse method of fastening. A screw was a common way to attach spring-gun piston seals in the 1950s and ’60s, but it wasn’t a good way, because over time the screw threads corrode and cement the screw in place. In the case of Michael’s rifle, the corrosion is particularly bad, so that screw wants to stay put. read more

This report covers:

  • How can a ball be a sear?
  • Three balls instead of just one
  • How the trigger works
  • Seen it before
  • Discussion
  • Summary
  • Last word

Today I’m going to try to explain how the Diana ball bearing trigger works. This is a design that seems complex, but once you understand it you understand a lot about how the Diana 27 goes together.

How can a ball be a sear?

A ball can restrain something from moving by blocking it. When the ball moves out of the way, the item that was restrained is free to move. Let me show you.

ball sear 1
In this view, the ball blocks the large bar (which represents the piston) that is being pushed by the force from a spring. As long as the ball doesn’t move, the shaded bar/piston cannot advance. The ball cannot move because there is another bar restraining it on top. read more

  • Summary

“Tis the season!” Ho, ho, ho! Here comes Santa’s helper, The Great Enabler, with more goodies you can’t live without. Today we begin our look at the Air Venturi Nomad II air compressor.

Air compressors for airguns

Before I start looking at the Nomad, let us review the world of the high-pressure air compressors for airguns. Modern precharged pneumatic (PCP) airguns need a source of high pressure air to fill them. Of course there are all manner of air tanks, but there are also air compressors that can fill either the guns themselves or refill the tanks. And let’s not forget the hand pumps that exist — they are pretty special, too. Which you get — tank, hand pump, compressor or even a combination of them — depends on what you can afford to spend and also the air pressure(s) your gun(s) rquire for a full fill. read more

  • Discussion
  • Summary

Today I shoot the Sig P320 M17 pellet pistol for accuracy. I learned a lot in today’s test, so this should be interesting.

The test

I am testing both pellets and BBs (plus lead balls), so I will test at two different distances. I will begin with pellets at 10 meters. I knew that Sig Match Ballistic Alloy pellets would be accurate, so I started with them.

I started the test by shooting off a sandbag rest. I rested the bottom of the gun’s grip on the bag and I also tried holding the gun with my hands resting on the bag. It turned out that resting the pistol directly on the bag worked the best, but I had to shoot a second group to learn that. read more
