I am planning on building a pneumatic cannon, and before I start, I always wanted to make a breech loading cannon, so I am wondering if breech loading can be air tight. I want to know if breech loading works for a pneumatic cannon.

Thanks, :o

A slip coupling could be slid over a loading port cut in the barrel right after the valve. They have seals and don't need to be tightened to the point it won't slide easily.
