Just put together my form 1 can and was wondering what everyone likes to feed suppressed 9mm
Thanks for the super informed post. I ordered some 147 fmj so we'll see. I'm not sure I can tell wearing hearing protection. As mentioned elsewhere I tried Stelth 165gr and it was super quiet and accurate, but underpowered to cycle the action (thanks for the education on PF) I can still shoot those for sound comparison.But with a can on you will know immediately if the bullet is supersonic. I would be extremely surprised if you found any standard pressure ammo to be supersonic with a 147 or heavier bullet.
