I dont know about the suppressor.I'm about to rebarrel a tikka 30-06 to a 9.3x62. I'm wanting something shorter because I'm going to suppress it. Will I regret getting a 18" barrel vs a 20"? The suppressor is 7" long and 10 oz.
Twist rate, yes if planning on shooting heavy for caliber bullet, example being a 200 or 220 grain bullets out of a 308 Winchester.I’m guessing the twist rate and bullet design need be factored in before cutting.
