Aluminum 37mm 3" Launcher Casing Hull

37mm Aluminum 3" Hull

Empty re-loadable 37mm launcher hulls. Accepts standard 209 shotgun primer. You can use these to reload flares, smokes, and firework rounds over and over again. These will fire out of any 37mm launcher. If your brand primer is a bit small, use a piece of tissue paper around the primer or, alternatively, seal the primer with clear nail polish.

Importantly, there is an integral bushing machined into each hull.  These bushings have two purposes.  First they allow for the same positioning of the payload each time. They also keep the cannon fuse part of the payload safely above the base of the shell so that it does not get crushed.
