since the Beowolf and the .500 s&w mag have almost the same case capacity, one could make a general comparison of the velocities of these two rounds...only problem is that the velocity of one is in a short handgun and the other is in a longer rifle barrel. Even so...the rifle velocities are still very similar to the .500 mag handgun velocities for any given bullet weight, so I would expect the beowolf loads are in the mid to lower range pressure levels. Remember this beowolf round is designed for a semi auto action on an aluminum alloy frame.
