577 snider snap cap

This is a snap cap for .577 Snider. It is for function testing and loading and unloading practice with the Snider rifle.

Once printed sand smooth any bumps or extra plastic. Then try it in the rifle. If it dosen't slide in easily don't force it, just keep sanding until it slides in and extracts easily. I used finger nail sanding boards to sand and polish the cartridge.

The hole in the bottom can be filled with silicone to provide a cushion for the firing pin.
