I absolutely love the 454 Casull. Compared to my 500, it's a tame gun.
I have the 454 in 3 varieties.
Super Redhawk 7.5"
Talo toklat 5"
Alaskan 2.5"
Recoil beteeen the 7.5" and 5" is not much difference. The 2.5" is stout but not unpleasant. In fact, I have shot 357 Magnum Snubbies with more pain than this. The weight and girth of the Alaskan makes it a controllable revolver.
When I first shot it, I had a difficult time controlling it. I have shot it 45 times, first outing. 50 or so second outing. It is a lot better each time I go out with it. I have some bear load 454 Casull 340 grain bullets to try out.
The Alaskan and Toklat were not zeroed from the factory for standard hunting loads. It was 8" low at 15 and 25 yards.
I have a Bandolier Holster for the 7.5" and I have a Grovtec chest Holster for any of the three revolvers.
Against bear, the most important thing is load. As I may have quoted an article, the 4-3-1 rule should apply: 4x Magnu, 300+ grains, 1xxx FPS.
These are my backup carry guns for hunting and hiking.
