So, I just picked up a nice Darrel Holland 22-250 Ackley Improved. I have 22-250 dies, brass, bullets etc. Please let me know if the following procedure is correct or if I have missed something.... Fireform 22-250 brass in my 22-250 AI. Neck size the brass using RCBS neck-sizer die for 22-250. Reload said fireformed brass and shoot 22-250 AI and continue neck-sizing. So, I don't need 22-250AI dies? I would only need them if using 22-250AI brass from someone else's rifle?
