I normally shoot the .458/300 Nosler for elk season and they really do work well... as for the 300 Bonded SW I have one concern - to many
reports (not first hand knowledge) of the bullet, and I will use Semi's term,
penciling throughthe animal at close ranges and with a heavy propellent charge. Now if you add in the thickness of an elk hide and the load you you suggest 120 T7 it could be just fineespecially beyond 100 yards - I would be inclined to go with a 100 grain load and still would bet you would get a complete pass through.
Any chance you could find some .452/300 grain Speer Golds? I would stake a lot on that bullet doing everything you wanted even at 120 grains from 25 to 200 yards.
