I need some help. Hornady factory ammo for my .223 using 55 gr. V-max bullets have outstanding accuracy. I have burned thru 100 bullets using H-335 and Varget trying to get close to this but can't compare. I'm next going to try some H-322 but was wondering your opinions? I know that it likes the bullet but which powder comes close or which powder does Hornady actually use for factory ammo?
