Unissued Barrels for those CZ's sell for reasonable prices. So you don't stand to lose much by giving the chamber a polishing.
10-4! http://whatacountry.com/cz52barrel762x25.aspxBesides, I don't plan on botching it!
just get an old brush and wrap it with some steel wool, throw a small amount of flitz or simichrome on there and chuck it in a power drill.zip it a touch, and test. zip it again, and test until good.
I'm aware of that method, but IMO an equally judicious approach w/case lap would yield more consistent, concentric results.
The amount of metal you're talking about removing is minimal, so going through all that trouble seems a little excessive.
Yup, minimal metal removal, just what I plan to do.
Trouble?... pull a bullet, knock a primer, drill a hole... child's play.
The brush/steel wool/polish lick isn't all that much much easier.
Besides tinkering is half the fun!
