Many of you have been reading this series in which I tune reader Michael’s Winchester 427 that is actually a Diana 27. This is not an air rifle for beginners to learn on! The mechanism is too complex for first-timers for a number of reasons that should become clear today.

SHOT Show

I have to tell you — this is a very lengthy report. I won’t get it all done today, so Monday I will finish up. And on Monday I will be in Las Vegas at the SHOT Show. I won’t see your comments as frequently as usual while I’m there next week, plus after I walk out of the show every day I have to go back to my room, write the next day’s blog and have it ready to publish by 9 p.m. which is midnight on the east coast where the WordPress server publishes the blog. So please don’t ask me any lengthy questions. I am not going to have dinner with anyone this year, so I can do my work without being whipsawed! read more

Slavia 618

This is my original 55 year old Slavia 618 in its new “firewood” stock. I made this one in a “camo” style, using cherry and maple blocks in a random arrangement of the pieces.

This report covers:

  • The Firewood stock
  • Why firewood?
  • How do we do this?
  • Some design considerations
  • Is your wood dry enough?
  • What if I want to start right now?
  • Microwaving wood – how does it work?
  • Art or science?
  • Microwaving wood summarized
  • Working with the blocks
  • Summary

The Firewood stock

And now for something completely different – an additive construction stock made from firewood. I’ve made a couple of these and have been pleased with the results — there’s lots of artistic opportunity to make a stock that is special. read more

This report covers:

  • The test
  • Hobby pellets
  • Crosman Premiers
  • RWS Superpoint
  • Discussion
  • Summary

Today we look at the accuracy of the Crosman Mark I Target pistol. After adjusting the trigger in Part two, I feel confident it won’t let me down.

The test

I put in a fresh 12-gram CO2 cartridge. We learned in Part 2 that there are around 45 full-power shots in a cartridge and I plan to shoot less than that in today’s test. I will shoot a 5-shot group on high power and a second 5-shot group on low power with each pellet. That’s 10 shots per pellet times 3 pellets is a total of 30 shots. The range is 10 meters and the gun is rested directly on a sandbag. Let’s go. read more

  • Couldn’t get the rifle to group!
  • The double group
  • Sandbag rest
  • Wraith Ballistic Alloy pellets
  • I can do this!
  • Air Arms domes
  • Air Arms Falcons
  • Last group
  • Summary

Today I start looking critically at the accuracy of the new Sig ASP20 breakbarrel rifle. Until now I have only shot 5-shot groups. They are okay for quick work but do not tell the whole story. Today I will shoot 10-shot groups and we will learn the accuracy of this new rifle with some precision. I won’t get into the statistical reason that 10 shots are better than 5, but here is a good bottom line — anybody can get lucky, and it is far easier to do it 5 times in a row than 10.

The Whiskey3 reticle

Before we get into this test report, reader Bimjo asked this. read more

Parts of the hand

parts of the hand
Legend: These are parts of the hand that I will reference in my discussion of the grip.

I made this legend so that it will be easier to follow my explanations. In the picture, my grip is relaxed and open so I can label the parts clearly. When actually holding the grip, my thumb (1st Digit) would wrap around the grip causing the Thenar region to move down to follow the top of the Palmar region perimeter (purple line), and the 3rd, 4th and 5th fingers would be curled in more. read more

This report covers:

  • Reader MarklinJHawkland
  • The blind pin
  • Sheared the screw
  • The lesson
  • Cleaning the spring tube
  • Other cleaning
  • The assembly
  • Summary

I’m tuning and overhauling reader Michael’s .22 caliber Diana 27, which is actually a Winchester 427. In Part one I disassembled it and in Part two I showed you how the ball bearing trigger works. In Part three I talked about removing the old piston seal that had a screw that was stuck. I have a lot more to say about that today.

Reader MarklinJHawkland
This is the reader who solved the puzzle. I knew there is a pin in the head of the piston, because when I disassembled the rifle someone had tapped that pin in far enough for me to see it. Unfortunately it was probably that and not the rust that had jammed the screw in place. read more

A Round Tuit

round tuit

Well, it took me a while to get to this, but now that I have a round tuit I can start doing the velocity test on this old gal. Since I spent most of a warm, calm, sunny Sunday shooting this air rifle, you might want to make sure you have a full cup of coffee before you go much further. read more
