Having been shooting suppressed weapons for a while now I was wondering if a CF suppressed rifle would be hearing safe indoors. I decided to find out. Shot a .243 running 105 Amax @ 3100 fps from across the room to my steel at 150 yds. from the window. I gave it a go using hearing protection for the first shot as I was unsure. Here is the video of the second shot which was hearing safe. You can hear the round smack the steel. Muzzle blast was much less than I expected. Watch the stack of paper in front of the rifle.
