    I just purchased some "subsonic" 147g 9mm FP bullets from Missouri Bullets. What are "subsonic" bullets? How are they different from regular bullets? Any advantages? Or is this just a marketing gimmick? Thanks

    The are supposed to be slower than the speed of sound which should get rid of the sonic boom(loud crack) from the shot. Sub sonics are real popular with suppressors because the suppressor gets rid of the explosion of gases leaving tha barrel and the sub sonics get rid of the loud crack
