Re: Bullet 'crack' at subsonic velocities? Update: Here's the video, I rushed it so it's not very good. I'll get the video put together ASAP and update. It would be great to get Brian Litz's, or Lindy's thoughts on this. I'm going to edit the video to include clips of misses so that only the crack is heard, and not the steel getting hit. Am I hearing the supersonic crack from the bullet 80 to 100 yards earlier after it dropped subsonic? Or what am I hearing? At first I thought it was the muzzle blast, but when turning up the speakers, I can hear the muzzle blast. There is quite a bit of noise as the bullet goes by, however it's not the high pitched crack that you get when shooting a very much supersonic bullet, it's a bit lower sound. I'm shooting 175smk's at 2650, conditions were 29.22" 48% RH and 45 degrees. ![]() ![]() ![]() Ok, I just got back from shooting a bit ago and was reviewing target cam footage from 1180 yards.
