Breech Loading Device for an Aircannon

[Villhime98c]

I have recently built an aircannon. It almost exactly the same as the one in the picture but is bigger. Iwant to make a breech loading mechanism for it so I don't have to get up and expose myself laoding it from the muzzle. I have a pretty good idea of how to make this kind of device but I want to hear your input on one.

Any loading mechanism will have to go in front of that ball valve, so it can't be a breech-loader. But top/side loading would be possible. Just cut out a section of the top of your pipe large enough to place a charge inside and mount it on a hinge with a handle and latch. If you're worried about losing pressure you could always mount some closed-cell foam around the edges of the opening.
