i was wondering how long of a barrel it would take to make a 147 gr 9mm subsonic load go super sonic. I will be getting a 9mm upper and suppressor and really need to know if i will be able to shoot an 11 1/2 or 10" barrel without worrying about the rounds going super sonic. how long of a barrel would it take to make a normal sub sonic 9mm round go super or is this even possible? I really wouldnt want to have to go shorter than 10" max.
Thanks for the help,
Jeremy
BTW, does anybody know if that 9mm Russian Silver Bear 145 gr bulk ammo would be subonic or not in a set up like im talking about, because that would be a great price(500rds=52.50)
