Thread: those guys that have match barrels...

Dont over-clean it IMHO. I remove carbon fouling and that is it.

Personally I think some copper is a good thing as it coats the bore. Reading some academic papers on advanced tribology (study of friction), very high speeds, = liquidisation of the copper = less friction = higher velocity. In a match barrel Ive observed 1/4 ~ 1/2 MOA lower for the first 1 or 2 shots until the bore is "fouled" / coated with copper then it settles down. I have seen this effect on more than one gun, in fact it seems quite common. Better accuracy is not something I have observed though, or heard of anyone else commenting on only the vertical effect on a clean v shot barrel.

If anyone comes across similar geeky stuff i'd like to read ti by the way.
