with any LC Nato brass the best is to full-lengh resize the brass and de-prime frist, then swage the primer pocket to get rid of the crimp that is used on Nato brass. Dillion makes a Super Swager 600 that does both large and small primer pockets. then clean and prep like normal. Once you have fire formed the brass to your chamber then use a neck sizing die. I use Nato brass for .308 because that brass is annealed at the neck and shoulder and the primer pocket. it is a little thicker brass so becareful when loading. rule of thumb is to start low and work your way up. hope this helps
