Suppressors often add a small amount of velocity. It seems they add 0-70 fps. You can google it and find several tests on it. I think changing over from the 308 is long overdue for mil IMHO. I like that they're at least looking at fielding some 338s.By any chance do you have any links that will verify the increase in velocity? I heard the "BOSS" on Winchester/Browning rifles enhanced accuracy but nothing on velocity.
