Made these models of the GAU-8 ammunition using drawings I found online. It is the ammunition used by the famous Gatling gun around which the A-10 thunderbolt aka warthog/tankbuster was designed.
I made models for the practice round(TP), high explosive incendiary(HEI) and armor piercing incendiary(API). They print really easy and look like the real thing if painted correctly.
