.375 H&H cartridge failure - help??
A buddy and I were out shooting yesterday, sighted in my .300 win mag, then we started on his .375.
Fired off a few rounds from an old box, and then opened up a new box of 300gr pmp. This box was about 3-4 yrs old, always kept in a metal case, cool and dry conditions.
I fired off a round which spat back some shavings and gunpowder into my face, luckily no damage except for a sore eye where I assume a bunch of burnt gunpowder got to me.
My buddy fired another round, with no problem, then the third round out of the box, the second he fired, spat back at him too. I dont quite know how to explain it, maybe there is someone out there that has seen this before and can let me know what the possible causes are and why it would have happened. There was no excessive recoil or anything like that.
It is quite worrying, PMP is the most common ammo here in Zambia, we dont get much choice and when we do it is hellish expensive. PMP is costing us equivalent of $150+ for a box of 20 for the .375.
I have a picture of the 2 rounds, I hope the quality is ok. If not I will try post new pics this afternoon.
