Im ordering the Brownell's Barrel Vise but am trying to avoid buying the $390 set with all the bushings. I would like to buy just the vise and just the correct aluminum bushing. My barrels all have a breech diameter of 1.198". Which bushing do I buy? Do I buy brownells #9 bushing with a bushing ID of 1.200, the #10 bushing with a bushing ID of 1.225 or the #8 bushing with an ID of 1.775?
