Thread: Winchester factory ammo, serious issue

A guy at the bench next to me had a whoopsy today. Shooting a 270 Mauser, the RO I hear a rather larger bang and have a geeze at what comes out of the chamber. Answer: ruptured case, damaged bolt face and probably chamber ( newish to him, 2nd hand off Voldemort) had a look at his other fired cases, and a few were showing long marks In the same place, so initially we suspected something with the chamber. Then another fella picked up an unfired round, and it had a big old gouge lengthways on the base of the case, as did over half of the remaining ammo in that packet!
