and has less effective range. shooting birds on the wing is stuntwork, really, totally impractical for shtf survival foraging. All animals and birds stop moving eventually, it is stupid to think that you just HAVE to fire at them every time you see them, and even dumber to make a lot of noise, calling in every enemy within 2 miles. A sound suppressor makes a subsonic 22 as quiet as a BB gun, and game doesn't flee when you miss with such a setup. nor do the other birds or animals flee or hide when you get a clean kill with such a quiet .22. So this setup is many, many times more effective for foraging than any shotgun. by having the 22lr conversion in a Mini-14, 223 AK, or Ar-15, you have the option of using the 1/4 mile effective 223, or the very quiet 22lr rd, and that beats the limitations of the 12 ga all to heck. snares and traps are far more efficent than hunting, and you don't have to expose yourself in daylight to use them, either. Ditto for trotlines, fish traps, and nets, of course.
