Stan;
have been away from home a day or so & had limited time on-line. I was not disagreeing with what you said. I am strongly disagreeing with being able to fire a shell totally unsupported & have it stay in the chamber without moving back.
On a gun with barrel threaded into the frame or receiver if this were the case there one would be no need for a lock on the bolt, other than enough to keep it closed until firing. There would be absolutely no concern of bolting strength regardless of type, trapdoor, toggle joint rear bolting etc, all would be equal. I think we virtually all know this is simply not the case, whether shotgun, rifle or pistol.
