[QUOTE="J E Custom, post: 1645686, member: 2736"] That's Great, But the fact that he had a case head separation stills bothers me. Case head separations are normally a sign of excessive head space that allows the case body to move forward before ignition and grip the chamber walls during ignition and the case head is forced back to contact the bolt face, stretching the case in the web. A case that Is to long, prevents this from happening, But raises the pressure because it does not/cannot release the bullet correctly. lowering the pressure will not change the head space and case head separation can still happen over time. If head space is correct and the chamber is correct and case head separation still occurs, the load was extremely over pressure and is setting the bolt lugs back or stretching the action. Ether one is not good. Just trying to warn the op that there may be other problems. J E CUSTOM [/QUOTE]
