Hey all, this may have been covered, but I'm not finding much useful info on it. Independant of rifle, why would subsonic 300 Whisper be any better than subsonic 7.62x39? If I understand everything correctly, velocity for subsonic has to be around 1,000 fps (given temp, elevation, etc.), so the only real variables will be bullet weights and BC (again, assuming similar rifling, etc). So why would a 200 grain 300 Whisper fly and better than a 200 gr 7.62x39? I keep hearing people make broad statments like 300 Whisper is the greatest thing out there, just trying to figure out why. Is it simply because it is a pretty easy conversion on an AR? I'm a bolt rifle guy, so none of that matters to me. question 2: assuming the above assumtions are correct, why would anyone make a suppressed 223/5.56 when a suppressed 22lr shoots only a slightly smaller bullet weight wise? (40-60gr 22lr vs 40-80gr 223). Thanks guys!
