I can outshoot the 25-06 with my 300 wsm with factory ammo 150 grain silvertips... with a lot less barrel wear and match it to more animals than you can with the 25-06. I am betting the 270wsm is going to easily match advertised velocities and be a better all around gun also. Based on what I have seen at the local gun shops and my not so local bassproshop these short mags are here to stay....
