What gun fired this 20mm round?


Recommended Posts

The 20mm casing is steel but may not go with the projectile. I am wondering if the gun that fired the projectile can be identified by the lands and groves? There are 15 on the round.

Looking around the internet, it looks like you have a early 20mm M55 shell with a M103A1 casing.  This round was ultimately used with the Vulcan 20mm gun.  I am not sure how early your round is.
