Sorry in my introductory post I didn't use perfect terms or vocabulary!
Instead of being in a hard core life or death survival scenario, if one had a "camp gun" or "trail gun" and was in a subsistance situation, for those of who have NOT commented yet ......
What kind of shotshell load would you choose in a .410 shotshell?
Or 20 gauge?
or 12 gauge?
And please, for the sake of this topic - please assume you didn't have time to pick a "perfect survival firearm" ahead of time, and had to be satisfied using only a shotgun.
BTW, conventional thinking "might say" 7 1/2's are only for smallish birds ..... and such and such a size was for "geese, turkeys, or whatever ..... "
but in a round like a .410 a pellet size like 7 1/2 gives a much denser pattern than 6's or bigger. In a larger gauge the #6's could indeed be a better all-around pellet size. Likely game would be grouse-size birds and hares or bunnies, or similar critters.
Thanks ahead of time for your input.
Added: Anyone who thinks packing a .22 rimfire in black bear or grizzly country as their sole weapon is nuts in my opinion. I didn't specify in my introductory post that a 20 or 12 gauge could be used for a degree of protection against bears (with the right loads), but then this thread was to ask about small game shotshell "survival" loads.
