My kids are getting old enough to start going on camping trips with me and my wife is interested in family outings so I began thinking about what I could carry with me to use for self defense against four legged predators that might see me and my kids as either a threat or a snack. I'm up here in Tulsa and so our camping trips can range from prarie to the southeast up into the Ozarks to the north and west. I don't really trust my 9mm to take care of business and don't want to be caught with a hunting rifle on my back out of season so i am leaning towards a revolver in either .44 mag or .357 mag. I worry that the .357 won't be enough to stop or deter a black bear, but I think would be more than enough for wildcat or mountain lion (correct me if I am wrong). The .357 is attractive because I could practice with .38's. I'm not really concerned with cost of ammunition, but if I could get away with something less expensive then I will. I have looked at .45 LC but its pretty expensive and I can get the same effect from the 44, and since I don't plan on going to alaska I can't justify the .454 casull (even though I want one real bad). So what caliber and what revolver would you recomment?
