interesting thread...
if for no other reason than the number of different roles that people envision a camp gun fulfilling. Literally, everything from "what would you use a camp gun for in public campgrounds?" to "Gotta be prepared for everything from grizzly bears to Tyrannosaurus!"
I wonder how much of the difference in views stems from the way that society in general, and outdoors men in particular, has changed over the years. Firearms probably enjoy more popularity among non-hunters now they they ever have. How many hunters do you know that spend a significant amount of time in "the wild" other than when they are actively hunting? How many people do you know that spend extended periods of time camping in truly secluded areas, where supplies are more than a half hour drive into town and the local convenience store? How many truly understand interactions between humans and wild animals to any degree? Are we more likely to encounter two legged predators now than in previous years (generations)?
I spend quite a bit of time in wilderness areas that are not easily accessible. In such areas, I am not worried about people much at all. There is reason to be concerned about large four legged critters, but prevention is by far the most desirable way to deal with them. Know what animals roam the area and what measures to put in place to avoid drawing them to your area, and how to interact with them should an unlikely encounter occur. A big bore sixgun is a constant companion on such adventures, but the hope is to never have the need to use it for any purpose other than hunting, or perhaps dispatching those ever troublesome targets of opportunity like the large rock across the river that is just taunting that it is too far away to be hit with a 5.5" barreled .45 Colt. A .22 makes a lot of sense for feeding the stew pot. A camp gun doesn't have to be the only gun available. It just has to fill the role you deem important.
Camp gun? Define it to suit your needs or concerns. It may well be something very different to all of us, for any number of reasons. Small bore, big bore, handgun, or rifle; if it does the job, it fits the description.
