The 20 mm is a specific size of cannon ammunition. Like most cannon ammunition, armed forces typically use 20 mm caliber weapons against large targets, such as vehicles, buildings, or aircraft. Though lethal against individual soldiers, 20mm ammunition is so large and heavy that its effects are inefficient against relatively small targets. The 3 most common types are AP (Armor Piercing), HE (High Explosive and HEI (High Explosive Incendiary).
This Replica 20mm shell is made out of solid plastic resin molded from a real inert 20mm AP shell. With their brass casing and colored projectiles, they are made to look like the real thing. 3 types are available - Black AP (Armor Piercing), Blue HE (High Explosive) and Red HEI (High Explosive Incendiary) They are NOT intended to be used as actual practice rounds.. These are great for any reenactor, cosplay, or historical display where the real thing is illegal or prohibited to use.
**NOT INTENDED TO BE USED OR PLACED IN ACTUAL GUN OR CANNON
