Suggest you safely re-load your own sub-sonic ammo. Fill the cartridge with Trail-Boss… A 16" barrel capitalizes on all the propellant, pushes the pro-jo under 900fps, cycles the action, pie plates @100yds and should keep your ears & wallet a lot happier…
Ive been looking at that very ammo. Hush 165gr 9mm for my sub2k, can you elaborate on what issues you ran into?
Frank KAS67 is no longer on this forum. There was a few issues with him and he was removed.
Got it thanks for three heads up.
Its not an answer to your question, but here’s a link to a pretty cool videohttps://youtu.be/7pOXunRYJIw of suppressors using high speed cameras.
