I am resizing LC brass with an RCBS FL reloading die. My question is: Should the brass go into the resizing die all the way to flush with the shell holder? This brass just does not want to go all the way. Is it a sign of being fed through an M-60? Thank you for your response.

Is there a particular die set hat works best when relaoding for the M1A? I have seen two variations from RCBS; the F/L and Small Base. Any thoughts?
