I have a new 338-300 RCBS die set. I was getting set up to resize 300 RUM brass to neck out to 338 and I ran into a problem. I have a Hornady Lock-n-Load AP and my RCBS 338-300 FL sizing die won't seat down into the shell plate. The threads hit the edges of the opening on the shell plate. All my other dies, including the RCBS seater die, have some relief cut at the ends of the threads so they clear down into the shell plate. Has anyone else had a this problem and does your FL RCBS die look like mine?
