7-8 years ago I bought a few hundred rounds, via Cabellas, of Herter's steel cased .308. I fired it in my M1 Garand (in .308), which I’ve since found out isn’t something you should do. I had a case head separate after firing, and have since read of other’s having gun explosions and such.
I swore it off in my M1, but fired a few rounds out from my Remington 700 without issues. The primers felt a little higher than the back of the case, but I can’t say I’ve compared them to other fired rounds.
So, have others had issues with this ammo, in bolt action rifles? Is the general consensus that this ammo was often loaded to too high pressures, which is what causes the problems with the M1 or M1A pattern, or is it something to do with the steel case, which the Springfield Armory manual for my M1A says in bold letters not to use?
I had just thrown the ammo in the bottom of the ammo dump, and had for zombie attacks only. But now with ammo being like Gollum’s ring (My Precious!!!), I’m temped to bust it out again and fire it off from a bolt action. Baring something like the ammo being loaded to such high pressures it blows the chamber up and or shears out the bolt lugs, what would the signs be if the ammo is too hot?
Bulged out primers – are we talking big bulges or just a little proud of the back of the case?
Blown out primers, or primers with holes in them?
Separated cases, as before?
I don’t want to damage my gun or me, but with a few hundred rounds of this left, I don’t want to pitch it just all from a single issue with a semi-auto rifle, than may have been from the steel case, not the loading.
Thanks,
