Abstract: A non-lethal projectile or a projectile for delivery of a substance (optional) has a tubular body casing (1) which surrounds a compartment (2) for containment of the substance. The compartment (2) coaxially supports a hollow tube (5) projecting forward within an ogival nose cap (8). An inflatable membrane (7) is located within the nose cap (8). On target impact the nose is displaced and permits a small amount of substance from compartment (2) to bleed through opening (6) allowing piston (4) to move forward uncovering ports (16). This action allows pressure gas to pass through the ports (16) and ducts to inflate the membrane (7). The piston is also free to move forward to discharge the substance through needle (5). The bag (7) thus expands rapidly and prevents excess penetration whilst spreading the impact energy over a wide area. The construction avoids the need for a charge to be contained within the projectile itself.
