Over the years I've had a lot of different .22s. Some barrels will lead up worse than others, and some of those barrels will seem to get more accurate after a few hundred rounds through them. I've thought it was just that the barrel was getting polished from the shooting and cleaning and becoming more consistent. I've gone through the fire lapping routine with a couple of big bores, but it's a pain in the a22.
So I want to polish up the bores of a couple of new .22 barrels. My idea is to take a .22 caliber bore snake, rub fine polishing compound on it (white rouge) and pull it through the barrel a couple of dozen times. I would only pull it from breech to crown so that it would polish in the direction that the bullet travels. To protect the breech mouth from being polished I was thinking to take a fired case and carefully cut the back rim off and put it in first, and then pull through the case.
So what does everybody say? I'll probably try it whatever the consensus, but just wondering if there's any ideas to make it more successful. I plan on doing it to a stainless Ruger factory 10/22 barrel first. This is a rifle I'll be putting together using an 80% receiver. I don't really want to take the time to put it together and shoot some groups before, but that's really the only way to know if it made a difference. Now my idea is out here, so this will make me get before and after and report it back.
This is probably a month or more off, I'm waiting on the receiver and some tooling. I just wanted to kick the idea around first.
