Yes, a 454 casull will work. Notice that he used the short barrel redhawk alaskan to defend himself.

"Besides these factors, I say if your going to go big for grizz then go big. SW makes a nice 2" barrel model just for this in 500sw. Thats the caliber I'd go with."

I'd forgotten about the 500 S&W. Another big revolver round that would probably do well.
