that stuff is kind of inconsistent though. Have heard that mv's fluctuate a lot.

The velocities given were stated from Lake City. BC is standard M33 ball. I know the Barrett M33 ammo that I shoot from my 50 runs about 2800 but I was going off the the info from Lake City.

Re: 50 bmg muzzle velocity???

The Lake City number is based off a muzzle velocity on a 45" M2 MG barrel. The 29" barrel on the AR-50 or any other bolt gun will be significantly lower as JimmyM40a2 stated, and will probably be a little slower than the Barrett ammo which is pretty hot.
