Kevin M it ain't your equipment. On my dillon 550 I can deprime crimped 223 with only a bit more effort than non-crimped. But that filthy stinking slutty putrid new-fangled 9mm S&B "NONTOX" range p-up is so 'reloading' unfriendly, be it the initial de-priming or subsequent primings, that it's best to toss it from the get go. There's something purposely screwed with the "NONTOX" stamped stuff.
Regular S&B of various eras and ages, while not stellar, and sometimes a bit difficult, is certainly useable. "THE POX ON NONTOX"!!
