a custom barrel will always be better made/finished than a factory one and that the rougher finished barrel is IMO where the copper equilibrium theory is useful
I don't think its ok where pristine precision is needed but for the guy who wants to hit gongs no worries
it's not good to think copper in the barrel is a good thing, with the copper equilibrium the coppering supposedly slows down
sniper 101 has a utube vid on this, a fouler barrel is not a good thing and needs lapping or replacing,
at the moment I am trying to revive a good shooter but a dirty rotten fouler with Tubbs final finish projectiles
it will shoot 3 very precise accurate shots from clean and cold then sprays to and inch and a half at 120
so far I have put 7 of the Tubb projectiles down the bore but it takes that long to clean I cant shoot them all in a day
I will let you guys know how it works out but if it doesn't it will be a re-barrel or sell it for heaps as it shoots 3 shots great
