I have been experimenting with s&b and cci SPP in 38spl due to some failure to fire issues and then decided to switch to rifle for something different and put the remaining cci SPP in a small container but obviously didn't get them all out of my lee safety prime as 2 rounds fired cause smoke and sounded very different and when extracting the fired case i noticed they both had pierced primers. I have since decided that any primers left over in the safety prime get put into a case and not emptied for later use.
I have a very good habit of emptying the powder measures when done using them buy emptying the hoppers and rotating the throw arm several times until not even a kernel comes out. I just got complacent with primers.
New guys take your time and watch what your doing. also some other advice for the new guys is if a bullet feels like it seated too easily or you pulled bullets make sure you resize the case for proper neck tension. I pulled 1 bullet the other night cause a v max made its way into my HP pile and just seated a HP in the same case and when chambering it the bullet pushed itself into the case.
