more cut cartridges, with descriptions
also, went to the range yesterday. highlight was my FAL having ruptured casehead. The kaboom blew out the bottom of the mag; other than that, the gun is fine. I'm planning on getting it looked over and check the headspacing just to be sure, but im pointing the finger at ye cheap steel wolf ammo, which i know FALs dont like. I dont know if the extractor tried to pull the case out while it still was pressurized, or if was not in battery when the firing pin hit; my buddy was shooting it and he was accidentally bump firing it quite a bit (i guess he couldn't handle the recoil) and/or i've set the trigger too light (~5 lbs from the standard 11 lbs).
if it was and out of battery detonation due to the bump fire, im a bit stumped; the firing pin is not exposed until after the bolt is locked and the carrier is at least 3/4 of the way over the bolt, i.e. that case is fully in the chamber. I have the problem case with me; i'll post some pics when i get the chance.
also, now i have a bunch of steel .308 that i dont know what to do with.
e. the ammo more specifically was the rebranded Herter's steel case; just googling the name brings up a bunch of kaboom posts :/
