[QUOTE="J E Custom, post: 1193663, member: 2736"] First, I consider a fouled being one that has fouled enough to effect accuracy. If you have a quality barrel, that should be somewhere between 3 and 5 shots. (There is enough copper fouling to show with a bore scope) and at some point beyond, about all the copper that can be laid down has been. What I call a fouling shot, is just one shot in a clean barrel to remove any oil and possibly season the bore just a little. after the first shot the barrel conditions remains fairly consistent for a few shots and is not effected by copper fouling. Once a barrel fouls or heats up, things change and not always for the better. One shot will/should not heat up a barrel enough to change the POI unless the bedding or something else is wrong. But after a few shots (Especially the big magnums) heat can become an issue. I would recommend that you clean your barrel back to the white, start shooting a single group with 5 minute pauses between shots keeping track of each shot and see what your barrel does. this should tell you what your barrels likes and at what point you need to stop and clean. All barrels are slightly different and sometimes need different care. J E CUSTOM [/QUOTE]
