Thanks for your cent's worth. I still don't agree with that statement.. barrels start to recoil up and to the side while bullet is still in the barrel, and same time bending a little in UP direction ! That reaction then means they are trying to CLOSE breech tighter, right ? THEN, how can
that same reaction at same time, try to OPEN action ? Makes no sense to me, LOGIC tells us different.
