I am going on a horseback Mule Deer hunt in Grizzly Country. I will be with a guide. I am told that it is advisable to have a side arm for protection from the grizzly bears. The simple choice looks to be a 44 mag, with hard cast bullets, but I'm interested in hearing what you guys are using, and what advantages and disadvantages you have seen. I am limited in the weight that I can carry, so that is a consideration. I have a 6" S&W 357 Wheel gun, and hoping it is reasonable to use that for protection.
