[QUOTE="Mikecr, post: 606681, member: 1521"] More of a nightmare in reloading than a solution to thickness variance.. What brass is this? How thick is it? Who chambered it? I think it's too much sizing. The brass will expand to chamber neck and spring back to ~.318". While your bushing selection is good for .309" it's too much bushing sizing -from .318". The brass will curl in at too high of an angle, leaving necks way overworked(possibly splitting), and undersize of calculated. Because there is almost no taper in bushings, you wanna be within ~5thou with them. If this is Win reloading brass, I would think it would be ~15thou thick. If this is the case why not cull the brass with so much variance, instead of turning it all to an undesirable value? [/QUOTE]
