New, unfired ADG brass in a factory box. Atlas Development Group built their reputation on exactly this kind of case — magnum cartridges running real pressure, where ordinary brass gives up at the primer pocket long before anything else wears out.
Thicker web and a tighter pocket than the commodity options, with case weight and neck wall held closer than most. In 300 PRC that translates directly into firings: this is the headstamp people move to after wearing out a batch of factory brass, and the one most serious builds start with.
Unfired means you set it up your way from the first round — no unknown chamber, no inherited shoulder, no guessing what pressure it has already seen.
