I need a rifle thats accurate right out of the box maybe with a scope I would be shooting mostly from less then 100 yards away maybe 150 yards away at the most. Maybe a .22 cal? I'd prefer a semi auto as I'd hate reloading after every shot. It would have to be under $300 since i just turned 18 and I am berely starting hunting. For now im only going to be hunting Jackrabbits and cottontail rabbit and squirrel. What would be the best rifle and what type of ammo should i use for each kind of animal?
