A solid dose ballistic projectile formed entirely of a cohesive mixture comprising biologically active material, in the form of grindable solid particles having an average diameter between about 7 and 25 micrometers, and biologically inert binder, and capable of withstanding the stresses imparted thereon when the projectile is propelled ballistically from a barrel and implanted in the flesh of a living animal.

A solid dose ballistic projectile shaped for penetrating the epidermal layer of a living animal and lodging totally within the tissues of the animal and capable of releasing biologically active ingredient into said tissue of said animal when lodged therein, the projectile comprising in a major portion a body consisting essentially of a uniform cohesive mixture of from about 70 to 95 weight percent of grindable solid particles, at least about 90 weight percent of said particles having an average diameter between about 7 and 25 micrometers, and at least a biologically effective amount of said particles comprising biologically active material, and from about 5 to 30 weight percent of a biologically inert, cohesive binder adhered to said particles, said binder being more compressible than said grindable solid particles, and said body being capable of providing structural integrity to said projectile when ballistically propelled at a muzzle velocity of up to about 475 m/sec and implanted within said tissues of said animal.
