20160025470 | RESUEABLE POLYURETHANE PROJECTILE - Improvements in a reusable polyurethane projectile are presented. The reusable polyurethane projectile performs like a bullet or projectile because the projectile is essentially the same size and shape of a bullet and can be fed through a normal bullet clip into the breach of a gun, fired and ejected. The reusable polyurethane projectile conforms to the rifling of the barrel of the firearm to spin the projectile and provide equivalent accuracy to a metallic bullet. Upon impact the projectile will flatten and then rebound to the original shape. Standard re-loading mechanisms can be used to install the projectile back into a prepared cartridge. The reusable projectile is fabricated from a casting process that increases the resistance of the polyurethane from melting when the hot gun gunpowder pushes the reusable projectile out of the barrel of the gun. | 01-28-2016 |
