  • Patent number: 11359897
    Abstract: The present invention relates to a bullet. More particularly, the present invention relates to a bullet including concentric and sequentially ordered cylindrical fore, intermediate and aft portions. The aft portion comprises a cross-sectional diameter about equal to the diameter measured across the rifle landings of the riffled barrel operatively to create a gas pressure build up there-behind while the rifling grooves and lands deform and/or cut the aft portion thereby to impart spin to the bullet about the central axial axis thereof. The intermediate portion comprises a cross-sectional diameter smaller than that of the aft portion, which acts as a bearing surface for operatively riding along the rifling lands thereby to inhibit yawing of the bullet while operatively travelling through the rifled barrel.
