I was checking out Bison Armory uppers - their barrels have a 1:7 twist. So without doing reloads of their 200 grain bullets, does anyone else make a round heavy enough applicable?
Bison Armory developed the 1:7 twist barrel to shoot 200gr bullets subsonic. Unless you plan on using a supressor with a 6.8 it doesn't offer any other real advantage over a 1:11 twist.
