Designed to be fired out of pump-action shotguns, this ammo is accurate out to 100 feet, thanks to patented fin-tailed technology. Parting lines, variable wall thickness, and sonic welding insures that the projectile is strong yet frangible, and in most cases will not penetrate the skin. Because the projectiles use no gunpowder, the discharge is 16 times quieter than a standard shotgun round. SRP: $39.99, box of 10. byrna.com
