[QUOTE="bigedp51, post: 1441989, member: 28965"] You said you are neck sizing only, try a standard full length die and size the case body and bump the shoulder back slightly. Do not go to a small base die unless it is necessary. A small base die will reduce the case diameter .002 to .003 more than a standard die. And the small base die will also push the shoulder back .002 to .003 more than a standard die. A small base die will size the case back to SAAMI minimum dimensions. And if you do not pay attention to shoulder bump you can end up with case head separations. I highly recommend the Forster full length benchrest dies with their high mounted floating expander. These Forster dies produce cases with very little to no neck runout. Just remember chambers and dies can vary in size and a skinny chamber and a fat die can cause your problem. [/QUOTE]
