I'm a firm believer that in a SHTF scenario, a must have food provider would be a .22 cal. pellet rifle. For about $9 you can get a tin of 500 pellets and feed your family on rabbits, squirrels, raccoons and even possum if you're really hungry........LOL!
And on rainy days, you can set up a pellet trap in your basement and shoot all afternoon long........
I have three,yes they are awesome,$3600 worth,not including the glass.
