Dear Lord. At 2:51, those db numbers are terrible. I thought I picked up a lot of slap back echo at the beginning of the video when they were first shooting. Turns out, I was. 147 gr Federals SUBSONICS are at 138 db. That's at the point where you really should be wearing ear pro and are going to ring your ears when you pull the trigger. A human ear cannot differentiate 2 or 3 db noise difference. Good gravy. I would be so embarrassed by those numbers. From looking at the chart, subsonic and supersonic are all performing about the same (db sound reduction-wise). Flipping awful.
