Oh man, I know I've NEVER cut too much off my primer pockets then put a max SAAMI load in there and actually SHOT it!!!
Seriously, if I ever did that again I would use them for "wife" loads... that is, SAAMI starting loads for the bullet weight I'm using... which would pro'lly be 55 grains... Heck, the primer doesn't even flow at those pressures... and if you want to make double sure that the primer won't flow, use the CCI 41's... Cup is thicker... They're a little more expensive, but cheaper than tossing the brass.
