I am getting a 6 BR project done by a gunsmith, he will put a 26 inch heavy Bartien barrel, Jewel trigger, McMillian A5 stock on a Rem. action. I am looking to use it for a long range benchrest rifle under 1,000 yards, using either 105 to 107 Bergers and Matchkings. Only issue bugs me is that the twist recommended by Berger is if using 105 Hybrids, then it needs a 1 in 7 twist and the 107 Matchkings require between 1 in 7 and 1 in 8. Shall I go 1 in 7 twist? I am curious what you fellows are using for your 6 BR's and its setups and what would be your freebore, shall I go tight neck or leave as standard neck using Lapua brass. Please guide me in the right direction and yes, I am not looking to go to BRX or Dasher since I already have the Redding dies. Thanks
