I have a new mould which casts a bullet of proper diameter for it's intended rifle. I need to seat gas checks without sizing the body of the bullet. IOW, I need to seat .30 GCs on a .314+ bullet but lack a size die large enoough to accomplish the task. Any suggestions from y'all? BTW, My lubrisizer is an old Lachmiller and has no GC seater as I understand newer ones do.
