Sabot spin-stabilized projectile

In a preferred embodiment, a sabot-type spin-stabilized artillery projectile tapering from a pointed nose to a larger-diameter body of columnar shape continuous with a flare base of circular cross-section, the flaring base flaring preferably at a flare angle of between about 4.5 DEG to about 9 DEG , the length of the flaring base as measured along the projectile's longitudinal axis ranging from preferably about 8 to about 22 percent of projectile length, where the length of the projectile ranges from about 8 to about 12 calibers with a body diameter (of the columnar shape) of about 0.8 to about 3 inches - where a "caliber" is the diameter of the columnar body.
