Keith, you could also use a shortened 22-250 seating die for a first step (with the seating stem removed). Then, run it through the shortened 22-250 size die. But I'd bet some of Stan's money that you can do it with with the shortened size die. The sharp shoulder angles are what gets us in trouble when trying to form cases like this. Best just to blow 'em out to fit the chamber, I think.
