Add one more vote for the 300 WinMag. My son's Rem 700 with a 3X9X50mm scope & sling tips the scale at exactly 8 1/2 pounds. Recoil is about as much fun as most people can handle and still hit at long range. He was raised on hard kicking guns so recoil is not a problem for him. I just don't care.
This is going to come down to how much recoil you want to handle. For friends that have 7mm RemMags they shoot very well because it is under their tolerance threshold. But if you can do more the 300 WinMag will deliver more- but not a lot more.
As you have noticed there are a lot of members who recommend bigger stuff. Believe me if you can they will do wonders at range. Eventually your going there anyway...
