I have a 22-250 with a 1:80twist 28' Pac Nor shooting 80gr SMK's for long range pd's. Currently using Rem brass that has been wt sorted. Which would be the best brass to use? Choice would be Norma or Nosler. Anyone forming 6.5x47 Lapua to 22-250 and if so what dies and how well does it work? Thanks for any help.
