Above- Test firing your shotgun is the only way to know what combination of shot, shells and choke will work best for you. Shotguns are different from rifles or muskets in that they fire multiple projectiles; most people know that. A rifle fires a single bullet each time the trigger is pulled. When a shotgunner pulls the trigger great bunches of pellets fly out the end of the muzzle. The pellets are actually round balls of lead, steel or other metal. Think BBs from a BB gun with the orbs varying in size, larger or smaller as needed.
