bad powder or bad primers?
I have been reloading for 4 years now. I have reloaded 10,000 rounds and I have never had this happen before. Recently I bought some WC 844 pulldown powder. I worked up some test loads for 223 with a 62gr bullet. I started at 20 grains and went up to 24 grains in 1 gr increments. I shot them yesterday much to my dismay they sounded like a 22lr, upon examining the barrel I noticed unburnt powder laying in there and the chamber. My action didn't cycle and the next round wouldn't go into battery until I cleaned the chamber and barrel. Enough of the powder was burning to send the round downrange. I have shot reloads from the same batch of primers without any problems. Would bad powder do this?
