[QUOTE="FearNoWind, post: 1091030, member: 50867"] Yes, sir, I did read that last post. None of us can be sure what caused your specific problem. It could be lots of things, not the least of which might be enlarged primer pockets. The point I was trying to make there was that when the powder charge begins to burn the primer gets pushed back against the bolt face and everything in the chamber begins to swell. The case swells to fill the void provided by the head space which in turn pushes the base of the cartridge back against the bolt face and, essentially, reseals the primer. That all happens in an instant. If the charge is too small, even though the bullet may exit the barrel "normally", the pressures may not be great enough to maintain a seal on all the remaining cartridge components and pressure leakage past the primer is a possibility. I'd just hope that you don't get caught up in a post hoc ergo propter hoc scenario that leads to false assumptions. In your situation I'd find some new brass, prepare loads somewhere in the mid range of the reloading manual recommendations, and try again. [/QUOTE]
