Besides the 300 Win Mag is gods plenty of rifle for anything in NA. As would be the 300 WSM. For me the 30-06 gets it done easily. I had a Mark Five 300 Weatherby for a couple years. It didn't do anything the 300 Win mag wouldn't do a lot cheaper and with less Recoil.
Total agreement on that what does it do that any 300 win or WSM can't do?
