[QUOTE="Mikecr, post: 899585, member: 1521"] Woods I'm not downsizing enough to cause that. If I sized down 3-4thou under, and then expanded, greater springback would lead to ever tightening bullet grip as you describe. And don't forget that increased springback also counters downsizing. So over time my downsizing springs back to ~2thou under instead of 2.5thou under. This is over many reload cycles though. [/QUOTE]
