Bring it, I have a 300 RUM that will make short work of that! IMHO short mags are junk that was brought out to sell rifles in a failing economy were people were not buying guns, they offer no real advantage over any standard mag that is already been out for several decades, its a fad that has been created, and promoted by gun writers that are paid by gun manufactors. Matter of fact, I have a 30-06 I would not hesitate shooting against it, velocity doesnt meen squat as long as you know your trajectory and know how to shoot. Why dont you tell me were the 300 WSM has ANY advatages over a 300 Win Mag. That is pretty much like saying a 7mm-08 will out do a 280, or a 308 will out do a 30-06, or a 40S&W will out do a 10mm. There is no comparison especially when you get to the heavier bullets.
