I am about to start a 223ai build I have a stock bottom metal and surgeon short action I just can't deciede on 7 or 8 twist and how long to run the barrel debating somewere between 20" and 24" minimum contour size is remington varmint/sendero max is 1.00 at the muzzle either way it will be heavily fluted. I am currently leaning toward a 22" 8 twist .900 at muzzle with 12 1/8" deep flutes threaded 5/8x24 so I can run my 308 suppresor on it.
I would like to get at least 3000fps with 75-80gr bullets anybody have any experience.
