I just ordered my first (first, mind you) suppressor. It's a Tactical Innovations TAC65. I have heard a little about first round pop with a suppressor and to my limited knowledge it has to do with the first round out of the suppressor being louder because it forces the air out (or something like that). I will be using this suppressor mainly with my Buckmark, so even high velocity ammo should be subsonic. My question is, will the first round pop be louder with high velocity ammo than with subsonic ammo?
