You are comparing a .270 winchester short mag to a .3006? Why not compare a .270 WSM to a .300WSM. That would make more sense and you could draw realistic comparisons of down range ballistics between the two calibers. Also realize that a .3006 can be loaded to drive a 180 gr. bullet to 2800 fps or 3000fps for a 165 gr. bullet which would both surpass what you can do with a .270 win. Not knocking the .270 but look at all the facts. Brochures from ammo makers trying to sell new stuff are not a good source of information to make comparisons from. Consult a modern reloading manual that has the new rounds included.
