I’ve thought about doing this as well and am not entirely opposed to it. Did you cut it back to 20” or go shorter? How do you like it? Any regrets?
My only regret was getting a replacement 30-06 barrel instead of just sending off the factory barrel to get chopped. Smith misunderstood my directions and I ended up with an 18” when I wanted 20”. With a brake the concision is nothing to sneeze at, but it’s great with the suppressor. No matter how short you cut, a 30-06 will be a little faster than a 308 and until you get out past 400 (probably further) no animal is going to notice.
