There isn't any dangerous game in most of North America, so bumping into old griz isn't a consideration for most American and Canadian hunters.
Exactly. It's about 600 miles from where I typically hunt to the nearest grizzly as the crow flies. If I was somewhere I needed a grizzly stopper and still wanted some long range big game performance from the same load I'd use the 8mm WSM with 220gr. Weldcores (it was born for that application). If I was just worried about stopping a grizzly and not hunting a deer species at the same time, I'd take the .50-110 or .416.
The 6.5mms and to a lesser extent the .270s are suitable for elk sized game. The 6.5s do it far better, but then we knew that.
