Just out of curiosity I tried sizing some 40 s&w with the x shell holders that my app came with. Using a dillon carbide die, about one and a half tubes into it i ripped a rim off and got a stuck case. Fortunately the dillon dies are easy to unstick with a small brass rod and a little hammer.
Guess i will stick with single stage brass prep. I still definitely like the app for boolit sizing PCed boolits and have also used it with the bulge buster on 40 to iron out the small bulge from the carbide sizer that they sometimes get.
I am potentially interested in the swager as that would be nice to batch run those pesky crimped pockets.
