[QUOTE="Tiny Tim, post: 3033614, member: 87887"] Am I correct in understanding that it is the expander ball that is crushing the necks? No way an expander that size should interfere with sizing a case fired in the proper chamber. It seems your expander is a little oversize ( should be bullet diameter of .257/.258?). What is the neck ID prior to sizing? Perhaps lube the case neck ID or expander or give more chamfer on the case mouth ID. Maybe polish the expander to make the OD smaller. Seems that a .258 would [B]maybe[/B] give a .001 interference fit, which seems loose for a standard factory die. Sorry, missed the point you could run it through in the seater. [/QUOTE]
