To all, I have given up trying to figure out this problem. Any ideas might help. Problem: When I use unfired brass and fire them 1 time with my top loads, which are not that hot, they extract perfectly. After I resize and reload the same cases (I full length resize them back to exactly what they are when new) and fire them again with the same load (bullet, powder, powder charge ect...) the extarction is somewhat difficult. The 3rd time they have to be tapped out with a cleaning rod after it pulls the sako style extractor apart from the bolt. Thank God I can reinstall it. Any ideas??? Anybody else experianced this? Rifle is a custom 300 RUM on a 700 action. Chamber is a tight neck .333 neck diameter. Brass is turned so that the loaded round 's neck is .331 and some are .330 Either one makes for the same problem. Is it that the round just generates that much pressure that cases are only good for a couple shots or am I missing something? I am also using Nosler brass. Remington brass isnt any better, in fact I can only get 1 firing out of them. The starnge thing is, it has only started doing this between the 400 and 500 round count. Thanks for any thoughts.
