When I do mil-spec case with crimped primer I use the Lee Universal decapper die. The decapper rod and pin are built a bit stronger and is easily replaced if broken and much cheaper. So far I haven't broken one yet in several years of use.
For removing the primer pocket crimp I use the Hornady primer pocket reamer head sold separately chucked up in my cordless drill. You can do a couple hundred an hour pretty easy.
