I’m looking at putting a suppressor on my Sub2000 and want
the best ammo that’ll still be subsonic, < 1,125 fps @70F.
I’m looking at some different 9mm 147gr, that is manufacturer
rated between 980-1000 fps at the muzzle out of a 4" test bbl.
My question is, how much faster would the longer 16" bbl of
the Sub2000 make those rounds when exiting that muzzle?
Appreciate any insights, as I’d like to buy the 1,000 fps round,
but not if long Sub2000 bbl boosts velocity up into supersonic.
