got a ? on barrel rust issues
aight fellas i've been around guns and been shooting since i was 6,i'm 42 now. i have always cleaned my firearms after use due to the fact that i was a lil paranoid that if i didn't the barrel would rust from the copper and powder residue. what exactly makes a barrel rust? is it the copper on the rifling or the powder residue thats in the bore? i've heard of folks sighting in their rifle before deer season and not cleaning it until the season is over. would all that copper and powder on the rifling and in the bore cause rust issues like pitting and such?
