black powder tech is very simple, you just need a mediocre blacksmith - and that’s just a strong man (or a woman, maybe) - and a little bathtub chemistry. basic black powder rifles are not the most accurate, you need rifling for that (grooves that create a spiral down the inside of the barrel of the rifle), but it’s easily doable. long/recurve/compound bows are an option if you have the knowhow and material science.
trapping/fishing is an option, as is animal husbandry, but hunting would never disappear
