Don't worry about the shorter neck on the cases. It gives you a tad bit more case capacity and besides, my Swiss BP loads seem to like that little bit more room. I just neck-size like I said. Haven't tried to just thumb seat and crimp. Used to do that with my old 45-90 Sharps but that is a single shot. I do it with my 40-82 Rolly Block but again, a single shot and using paper patch slugs.
