OK, I'll put in my 2 cents worth.
When I go out into the deep woods hunting or hiking, I usually carry a 357 Mag (either single action or double action).
I usually prefer the double action, but also feel very comfortable (actually more comfortable from big bad 4 legged protection concerns).
Why I like a 357 Mag in a full flap, closed bottom holster at my side is because it is an "all purpose tool!"
I usually take with me 8 rounds of really powerful self defense 357 Mag ammo, 4 rounds of 38 Special Shot shells, 4 rounds of 38 special. Sometimes I will take a little more 38 special in different loadings and a little less shot shell. This is combined with a plastic 10 round shirt pocket cartridge box. That is 16 rounds total (6 for the revolver and 10 in my shirt pocket.
This gives me options from self defense, snake shooting, adding a little small game to the camp menu for dinner, and making noise to let an animal know I am over hear. Most bear I have seen are at a distance running like made, and yet bears are my major 4-legged concern.
Since my single actions are Ruger's with transfer bars, I don't feel any concern about loading all six chambers. My Taurus double action also won't allow the firing pin to get past a transfer bar unless the trigger is held back, so I feel comfortable loading 6 in that as well.
The advantage of the Taurus DA is that I can open the cylinder to quickly rotate the cylinder to determine what will be fired next or change ammo. In a non-self defence situation, one usually has time for such things (even enough time to do that with a SA).
The advantage of the Ruger Blackhawk SA is that I can handload 180 and 200 grain "hot" 357 Magnum rounds that will bring down pretty big things. If I standardize on nickel plated 38 Special rounds and brass 357 Mag rounds, it is also not to hard to figure out the appropriate load for either a Forest Grouse or rabbit that looks like dinner.
Again, if the purpose is a camping handgun, I would suggest a 357 Mag as a reasonable "outdoor tool." Yes, a 44 Mag, 44 Special, 45 Colt, or 41 Mag would provide more power, but probably less options, unless you really like to hand load a lot.
