This reamer is tapered almost like a 44-90 st. If I don't full length the 45-90 cases they lack a good bit of fitting. Neck sizing won't work. I suspect that when the cases are fire formed , they won't get touched again other than depriving and cleaning.
I don't resize for either of my Shiloh 44-77's for greasers. And if I keep the cases I fire formed with patched bullets separate I don't have to size those either.
