What's up guys! New to the forum, and have a question for some of the experts here!
Got to thinking about this today, and would like for someone to help me to understand about it.
The Hornady TAP FPD 200gr 45 auto+p ammo is rated at 1055 muzzle fps. According to all info that I have read and heard, the speed of sound is around 1,100 fps. If the ammo is traveling less than the speed of sound where does all the noise come from??? I am saying this and am confused by this, because of the new M&P15 that I have had my good eye on chambered in the .300 Whisper! The concept of the .300 Whisper round is to travel below the speed of sound and have yet to see one in person, but the videos that I have seen online sure have me puzzled!
So I guess, in a nutshell, my question is how can the .300 whisper travel subsonic and be so quiet, but the .45acp travels subsonic also and is soo much louder??
Sorry if I sound stupid, just trying to understand!
