Hunting weapons are tools used to hunt animals for food or sport. The most common hunting weapons are the SPEAR, SHOTGUN, and RIFLE. A SPEAR is a pole weapon consisting of a shaft with a sharpened head, typically made of metal or stone. A SHOTGUN is a firearm that is usually designed to be fired from the shoulder, which uses the energy of a fixed shell to fire a number of small spherical pellets called shot. A RIFLE is a long-barrelled firearm designed for accurate shooting, with a barrel that has a helical pattern of grooves cut into the bore walls.
