The 300 wm is a superb cartridge, Just don't build it too heavy. The recoil is not that bad. I would aim for around 8 lbs, to mitigate recoil. The 30-06 is such a versatile round but the 300WM trumps it by 100 yards and for larger game. If I had to reduce all of my firearms to three it would be: 243, 300WM, 375H&H. This even though a major fan of the 7RM and 280AI.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
