Probably a PITA, you'll more than likely have to turn the necks, which sux.... Fireforming is very straight forward & most of the time good accuracy can be had. In the case of the 06ai, i'd probably go the corn meal method to increase bbl life.
Technically speaking, you could probably use Nosler 280AI brass & neck down the 1mm to 6mm.... you shouldn't have to turn necks then & the ackley shoulder is already formed.
