[QUOTE="Mikecr, post: 661195, member: 1521"] No, the indentations were exactly the same, even with misfires. There are at least two relative aspects/approaches to primer ignition; Speed and/or Power You can crush primers flat in a vice, slowly, without setting them off(but not always). As mentioned if the pockets are too deep, and primers not seated in contact with pocket bottom, you get misfires. This, even with normal indention. I believe the primer compound lead styphnate requires more shock, than force, to set it off. SPEED How a primary explosive can vary in it's ignited performance is totally beyond me. I used to think that once ignited, even if 'barely', it's output would be the same. Now I know this isn't true at all. But I don't understand why. [/QUOTE]
