I actually carry a .357 ruger 4" barreled Security Six as my outdoor beater gun. The first round in the chamber is a .38 load full wad cutter and the rest are full powered .357 158 gr. hollow points. I have shot many rabbits, bobcats, and a few deer with it. I find it to be an excellent all round camping gun. However, I live in the SW and do not have to worry about big browns or Grizzlies. All I have to worry about is Cats, small blacks, and two legged Vermin.
I came to this gun choice mainly because of it's versitility. I prefer a .22 for small game procurement, and a .45 (1911) is my service pistol, which I much prefer for defensive carry. When I hike I don't want to carry a long gun, and I want something that can act both as a defensive firearm and can assist in food procurement during long outings. (I usually am out for 5-7 days.) Doesn't take up hands to carry, (Terrain is very difficult where I live), and is powerful enough to make long shots (Over 100 yards) with some degree of accuracy. Most of all I am hard on my tools and I expect them to be rugged and reliable. And the price of the gun was great. 100$ from a guy deploying. So if I get a wee scratch on it oh well.
Just my .02
