I believe that the 300rum will run the 180 to 190 class bullets about 3400fps. No point in debating the potential velocity though.
If some one is going to run the big 30cal, then the potential comes in with larger bullets, like 210g to 240g. Along with more high bc offerings that appear to be on the horizon.
Energy is an arbitrary number that has nothing to do with terminal ballistics. Bullet choice has everything to do with terminal ballistics. Use a hunting bullet inside ranges where it has enough velocity to perform. Using energy as the deciding factor is like shooting dull broadheads on an arrow traveling very fast.
