Can Cannon Projectile

2 Versions of projectile for my AR mounted can cannon by F5 Manufacturing. At default size these are just barely too large to fit the launcher, and will require a little sanding. This was intentional as I wanted a very good seal to minimize blow-by and maximize velocity/distance.

The "hollow" version was created to cast in silicone and make copies in plaster. Because it will be glued down prior to casting, the hollow will not affect the casting, and allowed it to be mounted on a lathe for quick sanding. It may fly, but can't test it until I get my mold made.
