A dart syringe projectile, which comprises:

• a tubular body including front and rear ends and a bore extending between said ends;
• a needle assembly including a needle hub mounted on said body front end and a hollow hypodermic needle with a needle port, said hollow hypodermic needle received in said needle hub and projecting forwardly therefrom;
• said needle port being positioned in spaced relation behind a tip of said hollow hypodermic needle;
• said needle assembly including:
• an annular septum ring within a plunger;
• a substance loading passage extending from a front end of said plunger to said septum ring;
• and said substance loading passage configured for receiving a hypodermic needle of a syringe containing a substance for loading into a reservoir cavity;
• a tail assembly mounted on said body rear end;
• a striker movably mounted in said body bore or said tail assembly;
• a compression spring engaging said plunger and configured for rearwardly biasing;
• said compression spring compressing when said dart syringe projectile is in an inject configuration;
• a percussion cap mounted in front of said striker in said body bore;
• an explosive charge in said body bore in front of said percussion cap;
• a plunger reciprocably mounted in said body bore in front of said explosive charge;
• the reservoir cavity formed in said body bore in front of said plunger and configured for receiving an injectable substance;
• and said dart syringe projectile having a flight configuration with said injectable substance in said reservoir cavity and the inject configuration wherein in said plunger is configured to be propelled forwardly by said explosive charge and said injectable substance discharged through said needle port.
