Hmm, were we on the same squad at RB when the guy had 2 mags blow up and both times his brass was pretty much shrapnel? (He quit after 2). My guess was that his gun was firing too far out of battery.
(I hate it that s.o.'s are supposed to stand right where the turds fly on right handed shooters. I understand it but just don't like doing it).
Bulged 45 at the base was a problem for me. Bought one of the super duper dies that the others have mentioned, also it was suggested that I make sure my other dies are adjusted down as low as was physically possible so I did that as well. Am not sure which fixed my problem, but something seemed to.
I've got the size checker thingies (I can't help myself, engineers love gizmos of all shapes and sizes). On 45's some of my reloads flunk the thingie and they go into the practice only bag but so far none of those have caused any problem.
Wow! I'm glad everyone left with extremities in tact!
