.177 and .22 air rifle pellets APFSDS. Untested, try at your own risk. If you mess up that your own fault

The thing is pretty basic and my printer says it should take 5 to 6 minutes. Also this is untested, it could explode or damage property. TRY AT YOUR OWN RISK. I will try it in my airguns, and update it with a partially tested or unsafe depending on if it breaks or harms anything.

Resized down to common airgun pellet size (22 and 177)
