[QUOTE="nmbarta, post: 2119085, member: 78438"] Generally speaking, this is true. Generalizations, mixed with assumptions, mixed with reloading is how bad things happen. The rifle that blew up on me was an ar. There were no blown primers, or other indications of being over pressure. There was indications that something wasn't right. My accuracy dropped instantly from 1/2-3/4 moa to about 3 moa. At this point I knew something was wrong and I assumed it was something I messed up during my loading process. I also made the generalization that because I was not seeing signs of pressure that it was safe to continue shooting. Turns out, I was not over pressure. My barrel extension had started to fail, which was not allowing for the cartridge to chamber properly. This went on for about 40 rounds while I continued to try to figure out what was wrong with my load. On the last round of a five shot string, the barrel extension failed, luckily, the rifle did what it was supposed to do, and blew most of the gas through the bottom of the mag well. Aside from a fat lip and a loose tooth from the charging handle, I was not injured. Shrapnel blew through the side of the upper receiver, and made a mess of everything else. The point here is not to pick on you at all, just to point out that when something seems wrong, or your not sure why your seeing something odd, (like your velocity seems too high) it's time to stop. This is where I messed up. There is no logical reason for my gun to go from shooting 1/2 moa to 3 moa unless something was wrong, or something had dramatically changed. I'm sure if I would have looked with a bore scope, I would have been able to see what was happening, but I chose to continue tweaking my load. If your seeing numbers that don't make sense, or you don't have the experience to make sense of them. It's better to stop and get your rifle to someone that can verify what your doing is safe.
