If you want to make sure you have peace with your first rifle purchase, I think you should go with the 7mm-08 its a little faster and harder hitting plus it may be a while till you start reloading and the 7mm-08 will be easier to find ammo for. The 260 won't disappoint you with its work on deer though.

If you think you that you would have a hard time hunting hard and scratching your rifle I wouldn't get a pretty rifle. Rifles are tool meant to be used and abused.
