I used a charge that was outlined in the book so I assume it is fine to use as it was within the tollerance of what is considered a safe charge. No I do not know what primers I used because I do not memorize everything I do. That is what writing things down is for, and as I mentioned, could not referance to because it is all at my fathers. My crimps were consistant, just not heavy, which is something I will have to look into. If the bullet is being prematurly forced out into the barrel, I would assume the most that would happen is it would get stuck into the barrel as the pressure is being released through the cylinder gap and not being substantial enough to push it through the barrel which would cause a barrel obstruction, nothing more. The danger would be if I didn't catch the obstructed barrel before the next shot. I really can't see a hang fire it's self blowing a barrel. That's my understanding anyway, who knows I could be over looking something.
