I don't have any drawings before me but I suspect by the time you adjusted a set of .243 dies down low enough to do much neck sizing, you would also be resizing part of the body of the case and reshaping the taper.
I never really thought about that. But as I stated I have never reloadedany Ackley's. They say the P.O. Ackley bok is a good read. I guess I am going to have to find out???
I have had my eye on a 22-250AI. I would like to try to drive the 75 grain A-Max at 3300 or try for 3400 fps. The problem is I heard the bullet will not stand up to this velocity in a 1in8 twist??? Tom.
