Joe4d Posted August 21, 2022 Share Posted August 21, 2022 Which round do you is gonna win out in the midrange AR15 round contest and which will be the next Betamax ? far as factory ammo ? The Army has gone to a 6.8 but different case, 6.5 grendle might get a boost from creedmore popularity, 6mm ARC a bit of a range edge ?
