[QUOTE="ajhardle, post: 702453, member: 49861"] Well, I feel foolish. The brass is being dented by the feed ramp. That means my handloading technique and/or chamber specs are off. The lee collett neck die turns out rounds that measure near perfect on my rcbs concentricity gauge, but less than excellent groups. I see new brass shoot .20's to 40's when conditions are perfect, but by 3 firings, i' not bettering .60 with any consistency. The f/l sizer nets worse results. Maybe, that's the difference between a factory barrel, and one chambered by a good gunsmith? Any advice and insight is appreciated. Thanks everyone. [/QUOTE]
