WARNING! These models are not suitable for real world use out of the box as a 3D printed item. A better though untested option would be using these printed models to make a mold and then casting the models using a more suitable material and even so it is not recommended.

This was designed around one of the yellow plastic shells. Tapered style powder pocket holds 40 grains of black powder although you should independently verify this. The bushing must be epoxied or somehow semi-permanently
