So i went to the range today with my .308 (see sig) with a few friends. i ended up spending 5 hours getting free brass *roughly 32 lbs* and ended up shooting off maybe 30 rounds today. Long story short, I shot a total of 16 rounds of .308. my first 10 were some nato 147gr fmj stuff. all shot fine. i loaded up 10 PPU .308 soft nose bullets. 1st shot fired fine but seemed harsh (have an adj gas block and had it set to cycle 168gr amax ammo just enough). 2nd round fired fine but felt hot as well. 3rd round failed to chamber. i dropped the mag, round dropped out, as well as a blown primer. I checked the 2 other rounds, found the blown primer round and besides the blown primer, no other pressure signs. loaded the round into the mag and fired more. 4th round, fine. 5th round, fine, 6th round fine but 7th round failed to chamber. again, dropped the mag and round came out, with another blown primer. i picked up 4th, 5th and 6th spent casings, found the blown primer 1. 4th and 5th had only what i could only describe as a extra layered primer and 6th had the blown primer. I dont have a pic of the brass in question, ill see if i can get 1 up tomorrow, but it looks like if u took a normal, unfired primer, and put a thin layer of brass 1/2 the size on top of it, perfectly flat. anywho, after that I just stopped firing and went back to picking up brass.
edit:Only thing i found is if it was a cratered primer but without the crater (just the raised extra and perfectly flat)..not pic of my brass in question.
