You know one weapon that won’t run out of ammo? A Bow. (Recurve, Compound, Long, or Cross.) That is because the ammunition is reusable. Not my number one choice in a firefight but a good choice when hunting. There are two basic types of arrows that can be shot. Aluminum and Carbon fiber. They both have their plusses. Carbon Fiber is strong but expensive. Aluminum is heavier (more force in the blow), but bends easy. My advice is to stock up. This time of year, arrows are on sale since Hunting Season is winding down. What are your preferences? I am a Carbon kind of guy. Prep ‘em and keep ‘em. They don’t have an expiration date.
