and the noise and flash of a shotgun, the expense, bulk, weight and unreplacability of the 12 ga shell make it impractical for shtf foraging. Better to figure on using nets, fish traps and trotlines for your fresh flesh food,( if a silenced .22 conversion unit in the autorifle, or your .22 rifle or hg wont suffice). You can overlap woven wire fencing to make box traps for small game, fish traps, turtle traps, or fishing seines, and fencing is nearly everywhere, if you look around a bit. electrical wiring will snare birds and small game, and you dont need to stash all that much aircraft cable to be able to snare dog, deer, hogs, cattle, horses, elk, moose, bears. Read Ragnar Benson's book, SURVIVAL POACHING, and you will be way ahead of 99% of people in these matters.
