Frankly I know this has been dicussed but I was unable to find the discussion thread.
Has anyone ever checked the velocity difference on a TRG 22 308 with a 20" barrel vs a 26" I realize there are several things that come into play here, bullet weight, powder charge, etc. Is there a rule of thumb? 1"=20 ft per second.
