I like it. I've always thought of my M38 Mosin as a SHTF weapon, and I have ammo for it accordingly. Its cheap, dead reliable, and pretty accurate, even in my hands.
I would have to agree with one of the comments posted on the article, that a .22LR rifle is also a necessity. You can carry litterally thousands of rounds of ammo for the same or less weight as a hundred or so for the mosin or the shotgun he mentions.
I haven't researched it much, but I've never seen a Smith & Wesson for $200. Granted, I'm not much of a revolver guy, but I did some brief research recently for a decent .357Mag wheel gun and found everything with a S&W stamped on the side to be 400-500 on the low end. I'd love to learn more about this model 10.
In a SHTF situation, I'll also be carrying my SKS. Again, its dead reliable, not quite as accurate as the mosin, but for rate of fire and ammo availability, it can't be beat.
But we're getting out of the $350 price range here.
