As an aside, I personally have never seen any real need for the .300 Magnums. If I am hunting game that requires more than the .30-06 can deliver, more velocity won't solve the problem. I jump over the .300's and go straight to the .338.
The only situation where the .300 "might" have an edge is at EXTEEMLY long range where no ethical hunter should be shooting at game anyway. Even on the target range, the .338 will have less wind drift and near equal drop to the big .300's.
