The 7mm-08 isn't a bad choice. The only problem I see is it's almost identical in terms of velocity and energy when compared to the 308. The 308 is still cheaper and has more versatility in loads and can be found everywhere.

With that said, I see no problem with the 270, 7mm-08 or the plain jane 308. I just really dislike the WSM cartridges, because they cost a lot more, are harder to find and don't knock enough recoil off to be worth it. IMHO, if you want to reduce recoil get a limbsaver pad and buy reduced recoil rounds and you'll come out ahead if that's the goal.

As mentioned by the above poster black bear no problem, but I wouldn't hunt a grizzly with it. Grizzly is a different beast all together.
