[QUOTE="jarnold37, post: 2272621, member: 29241"] Some years ago, after chambering a smooth hand lapped barrel for a friend, he complained about the copper fouling on the muzzle end. He was breaking it in by one shot and clean. When asked by a well known action manufacturer, how was the break-in going I told him bad copper fouling. After a few questions on the cleaning method he said never shoot with a clean dry barrel. After clean put some lubricant in the bore for the first shot.On the first clean barrel shot, the friction of the bullet has the bullet basically melting by the time it reaches the muzzle. After first shot there is residue left from the first shot. But with clean barrel, it is dry metal against dry metal unless lubricated. [/QUOTE]
