[QUOTE="Dano1, post: 523563, member: 14209"] I shoot 3 Ackley improved cartridges. I turn necks for 2 of them. The .30-06AI doesn't need it, However I turn necks on the .243 AI when making my brass from .308 Lake City Match brass and I turn it for the 6.5-06AI because I make it out of .270 Win brass and I have a tight throat chamber. The key for turning it prior to fireforming it to not cut into the shoulder too far as to messs up your head spacing.... All Ackley improved design cases headspace off of this point while fireforming, so leaving enough is important as excessive headspacing will mess up the shoulder, cause casehead separations and other problems.....to find this point, turn the necks until the cutter slightly cuts into the shoulder, check the case in the the chamber and makesure it will still chamber with some slight resistance as it is crush fitting and headspacing. I then load and fireform and after resizing and cleaning, I check to see if I need to clean up the neck further, as the expanderball seems to push out any doughnut, this takes care of the problem for me. hope this helps, Dan [/QUOTE]
