NotesThis is an enhanced/improved penetration, non-toxic cartridge manufactured by General Dynamics Canada. It has a monolithic hard steel penetrator rather than a lead core with steel tip as found in C77 or M855 ball cartridges. The primer is reported to be non-toxic, and penetration is reported to be 20% greater than C77 ball cartridges.
