It's frangible. I don't care for frangible ammo at all (it's good to shoot at soft steel that other ammo would damage, but that's about it).
As for HPR, I've heard decent things. Apparently all american made with pretty exacting standards. So their ammo in general should be good stuff. But I just don't like frangible ammo for self defense so I don't care for the Blackops line.
