Like many other light anti-tank guns, the M3 was widely used in the infantry support role and as an anti-personnel weapon, firing high-explosive and canister rounds.
A spent canister round hit Frederick in the chest and he withdrew to the village of Elsnig in considerable distress.
The only 40x53mm type is the M1001 and is a canister round filled with 115 17-grain 2.0-inch long flechettes.
Here are two 40-millimeter canister rounds, just in case you get ambitious.
Immediately twelve five-inch double turrets fired canister rounds filled with flechettes along the average bearing-to-target in their area.
Their machine-guns and canister rounds proved telling during the fighting; the main attack stalled as it reached the wire before being repelled with heavy casualties by the combined firepower of the Australian infantry and tanks.
Further bunkers were exposed when the foliage was cut away by canister rounds and the infantry followed the tanks using rifles and grenades, while assault pioneers provided support with a flame-thrower as artillery and mortar fire engaged depth targets.
Other ammunition types include the canister and modified canister rounds.

A special canister round produced for the cannon contained 168 balls; a grapeshot version, with 48 larger balls, was also provided for shooting at 300-600 yards distance.
