I already have a goodly supply of this stuff, or I'd be all over it, but here's a plug, and a bump:
The reason I stocked up on Hirtenberger .308 is because of Fackler's report that it, alone, among the .308 FMJ he tested, gave results similar to 5.56 FMJ: half a tumble, snapped at the cannelure, and produced two wound channels. In his opinion, the most effective .308 FMJ out there.
For me, this is not cheap blasting ammo. Hirtenberger .308 is my TEOTWAWKI/SHTF/Zombie invasion/viva la revolucion ammo.
