Here in Ky, I don' t generally bother with a handgun while deer hunting...too much weight and no real need. But high altitude hunting in Colorado is another kettle of fish.
I'm a flat-lander and over 60 now, so those high passes west of Denver are a real challenge...having packed out elk quarters on a pack board at 10,500' before, unarmed, at dusk, in bear country...is an unnerving experience. But eighty plus pounds of meat is load enough without the extra-weight of an 8+ lb. rifle. So I've taken to carrying a Ruger .44 Special with some heavy Keith type loads for an unwanted bear encounter. In practical terms, one of S&W's Mountain guns in .44 Magnum would probably be a better choice.
And I'd readily agree that the guys here on the forum from Alaska or one of the lower 48's mountain states might have better recommendations; but holding off an interested bear while you shrug out of a meat loaded pack board with a hand gun sure beats being unarmed, and about the best compromise I could come up with. I'm more than willing to donate the meat to the bear's dinner menu...I just want to get out of the way, and not a part of the hor'doeuvres. (Sp?)
Best Regards, Rod.
BTW, I don't hunt with the Ruger on my hip...again too much weight...instead, I retrieve it and the pack board from camp after the kill for the pack out. I've done it three times that way over the years, and thankfully have not had to use the .44. The last time, though, I did encounter fresh tracks on my back trial a half mile from the kill site. It'll give you the willies for sure, but that Ruger sure felt comforting. Rod
