In attempting to handload 30 Carbine for the first time with all new equipment. I ran into some numbers I don't understand. I tumbled once fired cases, decapped, lubed in and out, then ran the cases through a new sizer die. The neck ID came out at .3035". The pilot on the manual case trimmer is .3055". No fit there so I can't trim to length. What did I miss here? I loaded a bunch of 40 S&W on borrowed equipment a while back with no such problems.
