Part 3

This report covers:

  • Rear sight comes off
  • The test
  • Crosman Premiers
  • Next up — JSB Exact Jumbos!
  • One more pellet
  • Conclusion

Let’s get right to it. Today we learn just how accurate is the .22-caliber Diana Stormrider I’m testing. In Part 3 I probably had difficulty seeing the open sights, but today I have scoped the rifle with a UTG SWAT 3-12X44 sidewheel scope. I have mounted it in BKL 30mm high rings. These are the thin rings with two screws per cap, because the Stormrider receiver doesn’t accept rings with a long base.

Rear sight comes off

The rear sight had to be removed for the bell of the scope to clear. The sight base, which is also the barrel band, remained on the rifle — just the adjustable rear notch had to come off.

  • Painted guns?
  • Summary

How old?

If you are new to the field of airguns there seems to be an ocean of things you need to know. If you want to become a collector, some of these things are crucial. Today I will explore how you can determine the relative age of a vintage airgun.

It starts with straight razors

Don’t worry, I’m not going to talk about straight razors very long. But they were the thing I used to rediscover what it feels like to be a new guy in an established hobby. Although I am not interested in collecting them, I couldn’t help but pick up some clues to their relative ages (when they were made) along the way.

Shape of the blade

Before around 1800, straight razors had no real tang. That’s the skinny part behind the blade where you hold the razor to shave. Razors from 1800 and earlier simply don’t have one. They just end the sharp blade and remain almost as wide but become dull as they go back to the pivot pin on the scales.

The acquisition

When my wife Edith and I lived in Maryland (1982-2003) we often attended the Columbia Flea Market. Once each month they held a Super Sunday when the market would expand by 500 percent. That was the day all the occasional dealers would attend, and bring the stuff nobody had ever seen. I found some tremendous air gun bargains there! Maybe I will write a report on just that — the deals I found and the deals I passed up. Today, however, I am starting a look at a Crosman 180 that came from that market.

We had been attending for more than a year and I believe I had started writing The Airgun Letter, or was about to. Because I was used to seeing vintage airguns at this market I carried several CO2 cartridges in my pocket, just in case. On this day one stall had this Crosman 180 and a .177-caliber 187 for sale. As I recall they wanted $40 apiece. I asked if they held CO2 and of course the dealer didn’t know. Then I asked if I could try my cartridges and she said yes.

They have the wrong twist rate!: Part 2

Part 1

This report covers:

  • Been awhile
  • New airgunners
  • A better way
  • Doing what works
  • The point
  • Sharpening straight razors

Been awhile

Part 1 of this report was written way back in the beginning of February. I think the reason it’s taken me so long to get back to it is I titled it wrong. I will discuss that as we go, but first let me define who “they” are. In the words of comedian, Red Green, “They” are everybody who is not us. Now that that’s clear we can continue.

Part 1 was a treatise on twist rates and how they affect accuracy. As many of you are aware, I use this blog to school both new airgunners and also airgun manufacturers — who are often as ignorant of the facts as new airgunners, but cannot or will not admit it. No engineer who has just been hired by an airgun company is going to admit there is something he doesn’t know about guns! Heaven forbid! And neither is any CEO or owner of a company, because in their minds they are in a position of authority and should therefore know!

Today we begin looking at the accuracy of the .22-caliber Diana Stormrider PCP. I know that many of you are eagerly awaiting these tests to make an important decision. Let’s jump right in.

The test

I shot using open sights from 25 yards off a rest today for several reasons. First, the Stormrider comes with open sights and, while a scope has to be sighted-in which can take some time to do, a gun’s native sights should be pretty much on all the time. The second reason I trusted the sights is the rifle I’m testing is one Pyramyd Air put through many tests already. Surely they have shaken it down before sending it to me.

Getting started with a precharged air rifle: Part 3

This report covers:

  • Fill options
  • Practicality
  • Filling a big bore
  • Tank size
  • Filling a smallbore PCP
  • The point
  • Air compressors
  • Booster compressors
  • Stand-alone compressors
  • The future

I said in the last report that I would write this report on filling options for PCPs. I’m writing this for the new guys who aren’t sure which way to turn. Any way you go represents an investment, so this is something that needs to be given a lot of consideration. Hopefully this report will start a discussion of that.

Fill options

There are two basic ways to fill a precharged airgun. Either the air is introduced from a container where it is stored until called for or else it is put in and compressed as the fill is made. The first option is based on an air tank of some kind. The second is either a hand pump or a small air compressor that connects to the airgun. I will talk about both of these but first I want to discuss practicality.

Before I begin, someone asked about Rich Shar. He’s the guy who smoothes the biggest spring guns like the big Gamos and Hatsans. Rich tells me he has not been working on guns for awhile, but he does have a project in the works. He promises to tell me more about it. Now, on to today’s report.

I have decided to take my Diana 27 apart and clean out the old grease, then relubricate it with Almagard 3752 grease, to see what difference it might make. But not today. Today will be a traditional Part 3 accuracy test.
