[QUOTE="bigedp51, post: 1406082, member: 28965"] In a semi-auto and pump actions the resized case should be resized .003 to .005 "smaller" in diameter than its fired diameter. This allows the case to spring back from the chamber walls and not cause any extraction problems. In a bolt action lifting the bolt straight up is called primary extraction and is to break the case free from the chamber walls. And pulling the bolt straight back is called secondary extraction and the case should be able to pulled to the rear with very little effort. And if you have hard bolt lift it is a sign the case needs to be sized smaller and have more spring back from the chamber walls. This is why the majority of benchrest shooters are now full length resizing their cases. This greatly reduces bolt lift force and the rifle is not disturbed and moved on the bags. Meaning the rifle does not need to be readjusted after each shot to align the scope on the target.
