Patent ID: 8096243

Claim:
A sub-caliber bullet having long-range accuracy, comprising: a forward portion, a mid-portion and an aft portion, said aft portion having an outwardly extending feature that contributes to aerodynamic stability; said forward portion being a first material having a first density that is in excess of 10 g/cm 3 and both said mid-portion and said aft portion being of a material different from said first material and having a respective density that is less than said first density; said sub-caliber bullet having a length, L, to maximum diameter, D, aspect ratio, L:D, of at least 5:1; and a diameter, d, of said entire forward portion and of said entire mid-portion satisfying an aerodynamic equation selected from the group consisting of Power Law equation: d=D *( x/L ) n where: x is a distance rearward from a nose of said sub-caliber bullet and n is a Power Law exponent that is between 0.5 and 0.75 and a Von Karman Ogive equation: d=D *((Θ−(sin(2Θ/2))/π 1/2 ) 1/2 where Θ=arccos(1−(2 *x )/ L ).
