I don’t trust ATK. Private FR mail me if you need .223 once-fired brass.
I don’t trust ATK either. The whole thing reeks of and end-run in the quest for profit. Brass is darned expensive right now, and this backroom deal “de-mil” of used brass conveniently works out in ATK’s favor - big time.
Many thanks for the offer; I think my & mine are all set. Perhaps someone else here can make use of your generous offer; "share the wealth", as it were...
