skeeter- point well taken and I agree. But when you compare the 300 WSM and 300 WM up to 180 grains, they are comparable but the WSM has better ballistics. Lets go back to my deer load senario in the Winchester Ballistic Silvertips.....my 300WSM is @ traveling 3300fps....the 300 WM is traveling @ 2950 fps. Not really a big deal but could be a deciding factor for a guy like me that wants every edge possible.
