I bought a .300 Remington Ultra magnum when I was 15 way back in 2005. The recoil was a little bit sever for my small frame, but I loved the Caliber, so to solve the problem i had a gunsmith instal a detatchable muzzle break. That solved all of the recoil issues that i had. And you don't notice the recoil when you are hunting, only when you are at the range. I would go for the .300 Win Mag Its a great caliber and it is more versitile than the 30-6 at long range.
