Just for comparison-
10MM - 200 gr WFNGC, 1350 FPS - 800 foot pounds. This is a HOT load, too. Probably your best bet.
.357 - 200gr WFNGC, 1315 FPS (6 inch barrel. You'll get more if you go 8 inch)- 760 foot pounds
NOT THAT FAR OFF. the 10MM isn't going to beat the .4*s.
.41 magnum - 240gr JSP 1,250 FPS (6 inch barrel) - 832 foot pounds. (this is a commonly available load- 250 grain loads at 1500 FPS- 1200foot pounds!! are common in handloads. Very underappreciated round.)
.44 magnum - 240gr. JSP- 1500fps (6 inch bbl) - 1200 foot pounds. Average hunting load, not ridiculously hot. You can cook it up, but I'd find an 8 inch barrel if I wanted to match the hot .41mag load and not mess with it.
okay, recap: nothing wrong with a 10mm, but it's a hot .357 type round for autopistols, NOT a .41 or .44magnum load. You also tend to run into problems running hot load in autopistols if they aren't tuned for it. I absolutely am going to prefer a revolver in a situation like this- canoeing or hiking, for a whole slew of reasons.
Mind, I'd be personally okay with a hot .357 load in bear country, and I AM comfortable with a hot .38+p load because that's what I take if bear, human, or cougar are my concern!
