i think its just in the amount of force pressed back apon you that the ammo is weighed in. grams,pounds for example depending on the weight of the ammo.

anywho really nice gun. my parents would never let me make one with such a long barrel..neigbhors would complain. (i spelled it wroung so it would be pronounced wrong lol)

Looks like a pretty nice cannon but why is the chamber so small compared to the barrel?

To do with the recoil thing. For every reaction there is a equal opposite reaction.

There for if you are shooting a 1 gram thing 100 meters for eg. the same amount of power to do that is going back at your shoulder.

So if your shooting 1 kg 100 meters, Your arm is going to really hurt.

To try this theory out yourself shoot a little bit of water out your cannon then a whole barrel full. Ohh and buy the way when you shoot water out of your cannon. Its loads of fun but can be pain-full. Prepare your self to go back a bit.
