Recently, I acquired a 629 classic deluxe after a bit of "horse trading". I will be working in NW Wyoming for a few months and while there, will attempt to perfect my fly fishing. Never been there before and am told that bears can be problematic. Among the major ammo manufacturers, can anyone suggest a readily available round which would be adequate against bear? I have a box of Remington HTP 240grn SP. I am reluctant to stoke this fine revolver with any high powered loads. Thanks in advance!
