20mm spent brass casings clean and in good shape. Limited quantities available.
20mm ammunition is mainly used in aircraft cannons, anti-aircraft guns, and naval artillery. Make sure to look at the pictures in comparison to the ruler to clarify how large these casings are!












This shell casing arrived quickly and was exactly what I needed for my project! Thanks for carrying this size and for the quick shipping! The rim of the casing was slightly dented but easy to repair in the course of the project process!
I’ve made a few “swagger sticks” for old Marine brothers using these as grips. The shell casings make attractive grips, and they’re memorable for anyone who was saved by a “Spooky” or “Puff the Magic Dragon” gunship firing 20mm machine guns.
