1Shot Wrote:If you are using a bolt rifle you will experience hard bolt lift and primer failure before you blow up a rifle no matter the caliber if you are using powders suitable for it. Depending on the bolt rifle it may never blow up but you may weld the action shut from flowing brass. Test have done this with the old Japanese WWII rifles which are some of the most robust of actions ever built. As has been said the AR is not meant to handle anywhere close to that pressure.
1Shot,
Reminds me of watching a mate accidentally load a heavy bullet used for subsonic on a column of powder used for supersonic, in Blackout. We were at the range and had brought scales and press to load test. He was using a 16" Rem700 put together by AA. There was an almighty bang and a huge amount of smoke out of the action, but you are right, the action held firm. Apart from the stout recoil he was fine, if not a bit shaken.
We could not prise open the bolt and needed to head back and use a breaker bar and hammer. The bolt was stuffed with the case welded into the face. We couldn't get it out. Never seen anything like it before. The gun had received a 'proof' load and needed to be retired.
In a light-weight AR it would have been a grenade.
You live and learn.
