Not interested in any of the ultra mag's at this point, nor any weatherby (the ammo is insanely expensive and hard to find, no thanks). I am really leaning towards the 300 WM at this point. It will give me that extra range just in case I ever need it and will allow me to do some long range target shooting (not that any of the others won't allow that). I know when I went mule deer hunting this past fall I could have had several shots at a nice mule deer, but they were 500+ yard shots. I feel like the 300 WM would allow me to take those shots.
Keep the suggestions coming though, they help a lot.
