I've got a 22 bra that I'm getting a sample of Alpha 6 bra brass for. The reamer specs says it has a .254 neck but it has been reground once, so I'm not 100% sure of neck diameter.  Anyway, I'll be necking down and turning. Is there a difference in necking down 1st then turning or turning as a 6mm then neck down?
