Yes 21st does have a small curve to the transition to AI angle. I got my mandrel turned today to fit the ID of the necks. The 5 cases I am going turn the neck now, in couple of days. You definitely need to turn your necks before sizing your cases, otherwise you push the uneven neck thickness to the inside. The only thing I am thinking about is cut the necks to length first before cutting the necks for thickness. I may play with a case or two to see how that going to work out in having the exact length. I am being anal on case setup.
