I'm w/ the majority here, neither are what I would choose for grizz, but I think the 30-06 w/ 200gr. would be better than anything the 7 mag can offer for grizzly. The 7mag would be great for the animals that wont take your rifle away from you and paddle your a$$ w/ it like a bear might

. I think you can use either, then get a 8mm rem, 338 mag , 325 short magect for the bear.
