that when sizing and lubing my .30 caliber bullets in my RCBS luber that one side of the bullet is burnished by the sizing die above the crimping groove (usually) while the other side is not.
I am using a top punch that is flat across and does not have a 'cup' to fit over the nose of the bullet. Is this an indication that the bullet is not entering the sizer straight on? Will a top punch with a cup built in it correct this? Does this even matter?
This is the first time I'v ever cast bullets for a rifle caliber and used a top punch of this design so I'm at a loss.
HELP!!....and many thanks.
