摘要:
An improved bullet disclosed includes a blend radius disposed between a first tangent thereof intersecting a shank of the bullet and a second tangent thereof intersecting one of a cone ogive and a boattail ogive of the bullet. The bullet also includes at least one dimple formed into a base of the bullet adjacent the boattail ogive, a curved segment joining the dimpled base and the boattail cone and a truncated cone ogive with a meplat end and a shank end, the truncated cone ogive adapted to produce less drag and friction in air than a secant or a tangent ogive. The improved bullet extends an effective flight range and a Coanda effect there around reducing air turbulence and drag on the bullet in flight. A cartridge adapted to receive the improved bullet is necked down and shortened for a COAL (cartridge overall length) nominally the same as conventional cartridges.
