The 7mm RM is my first choice when I am deer hunting...I have never had a deer go far, and most (all but one) have hit the ground where they were standing or running...
Hunting in heavily pressured, steep mountain terrain, I always try to put the bullet through the deers lead shoulder (both if the angle will allow it)...when that has been the case, every deer has dropped.
I started with the 160 grain Nosler Partition and found it amazingly destructive, as I did with the 150 grain Core-lok, and impressively destructive was the Winchester Supreme 150 grain Ballistic Silvertip that I now hunt with (and practice with out to 500 yards).
I have never heard anyone say the 7mm RM was not a good deer round...but every round that I have fired as exited, though the exit holes have been large to massive. I normally hear that the 7mm RM is overly destructive.
