7.62x54r - entire case split
I sold half of a can of ammo to a friend that just got a 91/30, since I still have a ton of ammo from when I got my M44. Well we opened it up and to my surprise I ordered russian light ball from aimsurplus, only I got russian steel core light ball instead :) (the tips are painted silver).
Well we shot quite a bit Saturday and right before we left we were cleaning up our empties and he noticed one of his had the case split all the way down, except it didnt split at the very front, just about 2mm from the very front of the neck and a few mm from the rim.
Is it something with his rifle or the ammo? He didnt seem to notice anything different when firing but he still hasnt cleaned the cosmoline from his rifle even though I told him he needed too.
