Title: Barrel segment as pellet checker.
Post by: stalwart on June 18, 2013, 02:22:13 PM
Had this left over after cutting 2 pistol barrels, and figured I'd try making something I could carry to check different pellets for fit to these guns.

Cut a leade and a crown, and free-styled a shape that is comfy in a pocket, and easy to tell the ends apart. Anytime I'm around pellets I haven't tried yet, I'll push a couple through.

Hoping this saves me cash, and cuts down on the typical "useless" pellet pile.

What do you guys think?

Not a bad idea.

If the Muzzle end of barrels cut ? ... due to choke present in the shorty segment, Nada  :P

Aw, shucks! Now you made me blush...   ;D

Good thinking. I'm cutting up marlin PB barrels, and most types will work... but, with a choke, a good tester would have to be sliced out of the pre-choked area. I don't believe it would have to be long, I just made mine square at the leftover length. I did it all free-style, so I still don't know any of the dimensions...and, frankly, Scarlet...

Thank you, sir.  8)

This thing does not need to be this big. As long as it is long enough to hold while applying a "sip" vacuum (to check initial seal) it's enough to check fit... assuming it's a decent barrel (consistent bore) to begin with.

From now on, I'll be making them to fit on a key ring.

Good idea. I am going to use the 7" 2240 barrel I just replace and do the same. I might also make a mouthpiece for it and it can double as a peashooter.

I think if you wanted to take full advantage of the accuracy as a pea shooter, you'd have to scope it.  ;)

The variations in production barrels would probably make a tester from one a poor predictor of the fit in another. In fact, a very poorly made barrel may have too much variance from one end to the other for a random segment to indicate well.

I'm using very consistent and seasoned barrels, the tester slugs out identically to the pistols. It will only be useful for them.

I like it!! Too many groups ruined by variations in head sizing from the same tin of pellets.

Although you couldn't check each pellet without scribing the rifling in, a random check of a small number from each tin might quickly point out which tins (mixed production lots) should be put in the "plinker only" pile.

I started a tin just for saving the slugs for that pile. They still shoot fine, and may show no effect from slugging (Micro Grooves do not tear things up much). Here's another... a better size.
