>>430306OP, I hunt squirrel and other small game with a .22LR, specifically the CZ 452 (foreground rifle, pic related).
You can hunt with lots of things, like crossbow, bow, slingshot, air rifle, shotgun, etc. depending on what's legal in your area.
You'll probably want a pack or satchel (Indiana Jones has one) for ammo, tools, water, snacks, and whatnot.
Bring a knife or two.
You don't need camo, just earth tones and natural fibers.
Don't worry about looking like a tard, because everybody was a noob at one point; just ask questions and don't try to pretend you know anything you don't.
