I'm Torn
The S&W 586 (4", .357 x 7) is handier, easier to carry.
Sacrifices some range and accuracy, but will still hunt.
I think, however, I would eventually side with Nem on this, and take my Marlin 1894C (.357 mag & .38 special).
Wide range of loads. Game, up to deer. Accurate enough inside of 150 yards. Even birds if you don't mind stalking.
I contemplated my M1 Carbine for a little bit. Assuming ammo availability, it's also attractive in the same way, although the range of loads of more limited. Rifle is light. Ammo is light. Accuracy acceptable out to 150 yards. And far more firepower than the 1894C.
Trouble with the question is the lack of context.
If
_I_ get to make up the context, then I can make a pretty good argument for each of the three I mentioned.
- Civilization on the rocks? I'll take the M1 Carbine.
- No breakdown, but rural environment? I'll take the 1894C.
- No breakdown, spend most time in towns/cities? I'll take the S&W 586.
Broadest possible context, with uncertain ammo availability? Gotta go with the lever gun.
Now maybe, once I actually
own a shotgun, shoot a shotgun, and have some skill with one, my view will change.
Right now I'm better with a rifle than pretty much anything else. Shocker there, I'm sure.
BTW, the OP question is an exercise in sadism.
Yer on a gun board, dude, what on Earth would possess you to traumatize these good people, making them contemplate giving up anywhere from a few to dozens of guns?
I mean, that just ain't
right!
