I'm planning a trip out west, and plan to do some hiking, knowing what i do about the bears out there I've decided it a good idea to take a precaution of the lead dispensing variety. I've narrowed it down to a very nice Model 70, 300 Win Mag, "Sporter Magnum" with 220gr Silvertips, or my Mossberg 535 with either hard cast .69 balls at 1600 fps, or a hard cast double .600 ball load at 1300 fps. For those of you who are more familiar with these animals than I am, what would be better suited to remedying a problem of the Ursid variety?
