Abstract : The present invention relates to a finless stable training practice round which can reduce gun-wear by use of a slow burning propellant. This improvement is accomplished without degradation of projectile accuracy or range. The present invention includes a projectile warhead having a spiked-nose attached to a boat-tailed cylindrical body. The projectile provides acceptable flight performance to a 2000 meter target without the use of stabilizing fins. Good aero-dynamic stability is obtained by selection of projectile, materials, shape and size so that the center of gravity of the warhead is positioned equal to or greater than 0.5 calibers forward of the projectile's aerodynamic center of pressure. Optimization of the location of the wear liner and the use of slower burning propellant provides for reduced gun-tube wear. The object of the present invention is to provide a finless stable training practice round which reduces excessive gun wear without reduction in range. (Author)
