Abstract
A modified projectile round which is configured to function with a propellant cartridge such as described in U.S. Pat. No. 7,004,074. The projectile assembly uses a High-Low gas pressure cartridge to launch the projectile. When the high pressure cartridge is ignited, hot propellant gases rupture a burst cup and shoot propellant gases toward the aft end of the projectile. The hot propellant gases impinge against a delay carrier located in the aft end of the projectile. The contents of the delay carrier are thereby ignited. The delay carrier includes one or more delay columns ultimately terminating in an igniter charge. The delay columns burn as the projectile is in flight. A specified amount of time later, the igniter charge ignites an ignitable payload—such as a marker flare candle.
