I just got my 22-250 die set and reloaded on a friends press until I get my own. I lubed my brass but I could never get the shell holder to touch the die. It seemed it was always catching at the very base of the brass. I set my die by screwing it down until it touched the full extended shell holder, then backed off the shell holder and dropped the die by 1 quarter turn. My Federal brass wouldn't set as much as my Winchester brass so I threw the federal brass out. The Winchester brass I could just barely see daylight through the shell holder and die.
Is there a break in for dies, or is it something else?
I am using the RBS lube pad to lube the brass. I can't think of anything else. I backed off the rod that ejects the primer. Is it possible I did not back it off far enough?
