Sounds like two really good choices to me. Personally I would go with the 300 WSM. But then that is the one I bought. And I like your rifle choice. I personally believe you are wasting your money on the bullets. Any good bullet from a 300 WSM will easily do the job on the game you described. No need to pay $1 a bullet, unless you just have alot of money to burn. The Barnes bullet will not be a dimes bit more effective than a good Sierra or other good bullet. Tom.
