A 20 mm shell typically has a cylindrical, metallic casing that contains a projectile, often characterized by its larger size compared to smaller caliber rounds. The shell usually features a pointed or rounded nose, with a casing that can be brass, steel, or aluminum, and is often painted in a military color, such as olive drab or gray. The length of the shell can vary, but it generally measures around 100-150 mm in total length, with a distinct rim at the base for extraction. Additionally, it may have markings indicating its type, manufacturer, and date of production.
