Polymer projectile having an integrated driving band
First Claim
Patent Images
1. A lightweight projectile combination with a casing, comprising:
- a projectile having a bullet shape and weighing less than 10 grains and sized to be fired in a barrel for firing traditional 5.56 NATO ammunition, the projectile having a body with a sealed interior space therein with marking media sealed in the space;
the projectile body having a frangible portion for releasing the marking media on impact; and
at least one metal driving band extending circumferentially around the projectile body and projecting radially outward, wherein the driving band is adapted to engage the rifling of the barrel to impart spin stabilization to the projectile.

Abstract
A lightweight projectile having an integrated driving band positioned around the exterior of the polymer base of the projectile for engaging the filing of a barrel to impart spin stabilization to the projectile. The driving band protrudes from the polymer base to minimize the contact between the polymer base and the rifling to reduce friction between the barrel and the projectile as the projectile is fired. The reduced friction allows the lightweight projectile to be propelled with minimal propellant force while still retaining the ballistic advantages of a spin stabilized projectile.
