Aggie,
BTW, the 1200 fps rounds will not be sub-sonic...at 100F, speed of sound is approx 1160 fps; at 20 F, it is approx 1075 fps (air pressure doesn't matter, temperature dictates with a little input from humidity).
You will suppress the detonation sound, but still get a sonic crack with 1200+ fps...but it still sounds cool!
