this is kind off how it will work but way better and improved. The concept s that the Shell will get help by a detacher to go very far up and be able to shoot over things like Mountains and be accurate.
News:
the things on the back dont completely stop it from Rolling back due to the recoil but they do help because of the shocks. It can be fixed by making them lift the back but that would cause a problem and with how i made them it fixed it.

Also i made the decorative Shells 'combustible' so that i dont have to make brass casings come out after each shot but they do still have the aft-cap and primer (the things that i kept the brass color.) Also i added a basket thing where they are suposed to go and i also added some of those in there so that it looks nicer.
