I hand loaded some 243 rounds for my sons 243 Ruger American. Twice now after ejecting a live loaded round it has become stuck in the barrel. What the hell? After the first time it happened, I went and seated all the bullets deeper in the case. The original length was well under my books and buddy's reloading books OACL. If you just drop a live round into the chamber and tip the gun up, it sticks and won't fall out. Please help as this is a major safety issue.
