Well, I'd look to what are the "toughest" handgun calibers, and which bullets to they use?
.460 Mag, .475 Linebaugh, the .500s.
Buffalo Bore uses a JFP of unspecified make, perhaps their own. Hornady uses the XTP, no surprise. Grizzly uses Hawk Precision bullets. Speer uses its Gold Dot. Nosler, Sierra, and Barnes seem to be the rest.
My experience? Never shot a bear with a .41, but I've liked Barnes X's on what I have shot. Having said that, if I were in your shoes, I'd use a 265 gr cast lead of the type offered by Buffalo Bore (assuming I could shoot it well, and that it was accurate out of my revolver).
Good luck.
It's called narcissism, and it's bad forum etiquette to continue to go off topic when the OP requests to stay on topic.
It's also bad form not to offer one's best advice; if that involves cast bullets, so be it. OPs do occasionally change their minds, maybe especially if they hear the same advice from several well-meaning (though, according to some, narcissistic) members.
