Here is the F.B.L.L.R.C., or Fixed Breech Loading Long Recoil Cannon for short. I like to call it Flubber.

There are FOUR types of rounds shipped with this scene: Pistol Rounds, Rifle Rounds, Blanks, and Pellet Shells
but now YOU can make your own bullets with instructions and a template.

It's also so consistent I set a laser to point where it lands, and it hits there every time, with the small bullets only though.
