Re: 300 WM, 300 WBY Mag or 300 RUM?
on pa whitetail, all 3 are going to give you close to the same results. the wby will have a little more ass than the wm, and the rum a little more than the wby. a 200gr bullet is going to wreak havoc on a deer regardless of whether its doing 2700 or 3100fps.
If it were easy, I wouldn't be doing it.
