Case head separations get my attention. A week ago, I was entered in a 50-shot match for "South of the Border" military rifles. I used my 1895 Chilean infantry rifle. A friend and I were sharing 100+ rounds of 1972 Chilean-made but poorly stored military ammo. I had a case head separation 10 rounds into the match. Had I not been wearing shooting glasses, I would have lost an eye. I have been picking tiny bits of brass and powder solids out of the skin on the right side of my nose for the last week. I finished the match with some handloads I had brought along, but my performance lacked a bit. I was awarded the Dianne Feinstein prize for the worst performance of the day with a rifle of known accuracy.
I have started to dig once more into the old reloading literature.
