Re: Project 375 ST
Well after a few fire forming shots I Pulled two cases apart that did not go off in the 375, which I first thought had DUD primers that did not go off. However when I tipped the powder out( dug out actually) there was a fair amout of burnt powder in the two cases, the primers had ignited and seemed to have burnt a fair amount of powder. I was running CCI Magnum primers, I was also using brand new powder ADI AR 2225 straight from the container with no chances of contamination.
My brother fired a few shots from the rifle and was convinced there was a delayed firing after the pin struck with a few shots he fired of a few micro seconds, This was noted before the miss fires.
I then switched to the hotter primers Federal GM215M, and continued shooting, The miss fire and hang fire problem has not returned.
