Since you mentioned deer and varmints, I'd suggest a .223, with the .243 as a 2nd option but is harder on pelts if you want to tan or sell the hides. The .223 is working caliber for whitetails on a good broadside shot in the vitals and can effectively take your fox, bobcat and coyotes without much damage to the pelt if you use the right bullets, as some are more devastating than others.

Shoot turkeys? LOL! Just plop open a hub ground blind and shoot them with a slingshot as they investigate your decoy.
