Forty millimeter caliber exercise bullet

A forty millimeter caliber exercise bullet is comprised of:

• a cartridge assembly (100) forming a cylindrical shape with hollow inside for containing a percussion primer (110) and primer housing (120) at a central lower portion,
• a skirt (200) forming the cylindrical shape with thread on inner surface of the lower central portion, outer surface forming a rounded bottom for fixedly inserting into the cartridge assembly (100),
• a striking pin (10) forming a circumferential groove (11) on its outer surface of the lower portion,
• a safety device assembly (300) consisting of a disk-shaped detent cover (310) forming a central seat groove (311) to rest said striking pin (10), a pair of sliding grooves (312) connecting to the central seat groove (311), wherein said sliding grooves (312) are arranged 180° angle in radial direction,
• a detent (320) for retaining said striking pin (10) by exerting force of springs (323) to engage or disengage to the circumferential groove (11), said detent (320) integrally forming a retainer (321) at one end and a mounting rod (322) at other end for retaining the striking pin (10) by engaging or disengaging into the circumferential groove (11), said retainer (321) forming either one shape of rectangular or cylindrical,
• a detonator cap (330) forming a hollow pocket (331) at its central upper portion to insert a detonator trigger (20), a washer (30) sequentially inserted from the top, a press-spring (332) installed for pressing a guiding cap (340) being encompassed said striking pin (10), and the detonator cap (330) being bolted to the detent cover (310), so that the retainers (321) are sliding outwardly by a centrifugal force to disengage the circumferential groove (11) of the striking pin (10) to impact the detonator trigger (20),
• an explosion pipe (400) filled with an explosive agent being threaded to the lower central portion of the skirt (200) for fixedly mounting the detonator cap (330) and the detent cover (310),
• a smoke shell (500) filled with a smokescreen generating agent, the lower portion of the smoke shell (500) is inserted between the upper inside of the skirt (200) and the outer side of the explosion pipe (400), and
• an ogive (600) for surrounding the smoke shell (500), the lower portion of the ogive (600) being fixedly inserted into the upper portion of the outer skirt (200).
