I just back from the range shooting a 10.5in 5.56 and a 10.5in .300. Neither is suppressed and the .300 had a 150 grain supersonic round. The difference in noise and concussion was very noticeable. The .300 produced less of each. If I had to shoot indoors without hearing protection or a suppressor, I’d would definitely reach for the blackout.

I don’t think anyone disputes that subsonic .300 BO is a lot quieter than supersonic 5.56 out of a short barrel.

Where exactly is sigspecops comparing a subsonic .300 BO to a supersonic 5.56?


sigspecops, the thread below would be a good place to share your findings.
