Here is a "Plate Test" projectile, this and other similar rounds were used to test the resistance of various types of Armour plate during the developement phase of Armour types like "Chobham" Armour.
With a calibre of 40 MM they were usually fired from a 40/70 Bofors Barrel with a varied charge for different velocities.
This one is constructed of a "Tungsten" core housed in a "Magnesium" body with screwed on "Nylon" driving bands-as you can see it is slightly corroded as "Magnesium" is very sensitive to Moisture.
The projectile will have been separately loaded with a cartridge behind it similar to B.L. Guns.
