[QUOTE="Scott S, post: 209888, member: 11324"] No matter how clean I get my rifle I am getting some pretty heavy copper fouling after about 8-10 shots. After these few rds my accuracy goes to pot and I get flyers everywhere. The copper build up is primarily is the rifling. I've used Butch's BS, Montana Extreme, and Sweets 7.62. Getting all of the copper out is not the problem. It just seems to be building up too quickly or am I wrong? I am shooting 180 gr Nosler Partition and 180 gr Accubond bullets. The rifle is a Win M70 FW 30-06 with 22" barrel. I've got at least 500 rounds through my rifle now. I don't have a bore scope so I was wondering if there [I]might[/I] just be some really bad machining marks/burs still in the barrel and that might be the cause of some inconsistent shooting? I know this is a question that is hard for someone to really answer without actually looking at my barrel but that is why I am asking "what do you think" might be causing the heavy copper fouling after just a few rounds. Maybe this is normal and my rifle just refuses to shoot after a few rounds. Thanks!! [/QUOTE]
