RE: .300 wsm or 30-06
.30-06 is a proven winner for so many years, you can find the ammo anywhere, many choices of grains, and bullets and you wont brake your wallet.
.300wsm, is becoming a winner it shoots flat, will take down anything the 06 would, ammo can be somewhat expensive.
recoil not much difference
As far as what to pick, you need to ask yourself what type of game will you hunting, the averge shot in yards would be?
If you will be doin mostly whitetail deer, and bear under 300yds. then stay with the 06
