Engel makes subsonic x39
Engel Ballistic Research
I doubt you'll find subsonic .300 Win Mag. I'd suggest using trail boss and heavy bullets. If you are shooting through a can make sure they are stabilized before putting the suppressor on so you avoid baffle strikes.
You buy the dies and bullets/brass and I'll load you up some, ill even donate the powder and primers for the first batch.
