Anyone know if it is possible to get a subsonic round out of a 300 WM with a 190 grain bullet? Buddy just bought a suppressor and the maker said that 190 grains was all he could shoot without voiding his warranty and/or risk not stabilizing the bullet enough to pass thru the suppressor. I can't remember off hand what twist the barrel is but I would assume 1:11. We are going to reload for it but just wondering if it is an option and if anyone has done it before.
