Abstract
The practice mortar shell with a sliding impact member projecting from its nose, has an inner perforated tube behind the impact member, and a spring behind it. This is housed inside a fixed perforated tube, also down the middle, from end to end. A bursting charge is housed between the outside casing and the outer perforated tube. Inside the inner tube is a pyrotechnic charge which is ignited by hot gases from the propelling charge. On impact, the holes through the two inner tubes are brought into alignment and the burning inner charge ignites the outer charge through the holes.
