UPDATE:
View attachment 7531231okay so first thing I did was set the primers deeper. I was just going by first resistance by feel (works perfect for my 6mm Creed, single digit SDs and never misfired). I reset all primers deeper in the primer pocket and tried firing them. No boom. Now today I got around to pulling the bullets and depriming the three rounds that did fire, and five rounds that did not fire. The picture below shows two of the primers that did not fire and the two on the right obviously did fire just fine. Is that color messed up?? I examined all the powder, nothing looks out of the ordinary. I then checked shoulders. I had set all shoulders back .0015-.0020. Ran the misfires through the shoulder gauge on my calipers and they’re ~.002 bumped from the fired cases. In one hand I want it to be bad primers so I know what’s going on, but if this is the case, I have 2,000 of the things now worthless. Comments??
