Hirtenberger is a top quality european ammunition manufacturer.
Is the stuff you have top quality.... probably.
Back in the day, when a man could get all the Hirt. he wanted, we sold tons of it.
I used the 7.62X51 Steel jacket lead core to harvest more than a few hogs and deer, worked great, expansion was not as great as some other bullets... but it did the job.
I never did any accuracy testing on the stuff but I could get 1.5" groups
(100y), on a good day, a real good day, out of the ol' enfield I shot it through.
Non-corrosive and reliable, at least the stuff I had was. 147gr Lead Core, Copper Washed Steel Jacket. I shouldn't think it would harm your DPMS, used in moderation... some say steel jacket is harder on the barrel than copper jacket... but THAT is another debate.
