I have both lengths of barrel and find the 4 inch much easier to shoot. they both seem to carry about the same so there is no choice there for me. very true that a .357 is not your ideal bear medicine, but it's gonna be more useful than the ultra-magnum, wizz-bang, stinger missle handgun that's so miserable to shoot and carry that it's sitting in your gun safe when you really need it. i have a shotgun, and several big bore levers as well as larger bore handguns and carry them all from time to time. i always have a ruger gp with a 4" bbl. with me. try some of the heavier stuff from speer or hornady. federal makes a 180gr. cast core that should be a good load, never shot it personally, though. if your a handloader heavy for caliber (180-200grains) cast loads are the way to go. good luck.
