[QUOTE="HMFIC, post: 1610530, member: 7539"] Typically, backed out primers are a result of not enough recoil to force the primer into a reseated position after firing. The thing here that is an indicator also is that every single round was tight in the cylinder after firing. So tight that you had to knock them out with a hammer. To me, this is indicative of high pressures rather than the normal low pressure situation that backed out primers is related to. I'd say that especially with the one completely coming out that you either got a batch of ammo that was hot, OR more likely primers that were too hot given that one popped. OR... it could be the gun. If there is anything about that gun that would make pressure rise then it could be an issue. Look at the timing and make sure it's precise. Check out your forcing cone area and make sure it looks ok. Does this happen with any other ammo at all? The thing that really blows me away is that the one primer came completely unseated... I wouldn't have thought there is enough room between the frame / firing pin and the case for this to happen. [/QUOTE]
