Here in Montana, I have settled on the .41 Mag. I think in the Taurus Titanium I can shoot it accurately enough to be effective with a stout bullet. But, as some say, save the last round for yourself. Seriously, I think the .41 is o.k. in the lower 48. In Alaska or Canada, something more potent than even the .44 might be a good idea for their bigger bears. But, I did read an article in a magazine I don't recall the name of, but the guy that wrote it regularly was in big bear country in Alaska, and he carried a .357. mtmuley
