Ok, I will tell you a stories that happen to me and my friend. We were playing with my coaxial and we were shooting stuff everywhere(in a safety place) And my friend got an idea. He said ; Hey what do you think about shooting water ??? I said; why not ? than we filled the barrel with water. We were 2 to hold the cannon. I was aiming with the cannon and my frend was holding the back of the cannon and he fired. We jump back about 5 meter from our initial place and my friend broke his arm. I am not kidding. Shooting water out of a too much powerful cannon is dangerous due to the huge recoil.

You should have rested it on the ground. When I shot water out of my combustion the gun just slipped out of my hands.

I don't if anybody mentioned this yet but 1 1/4 fittings are a good fit in 2" pipe. You could glue two caps back to back and fill it with sand or something for insane bullets.

you should try mini sandbags , heres a story about how I found out..

once i was at my freinds house and we start to shoot just about everything we found..

then we got bored with nothing else left to shoot,
soo we looked in his little brother toy crate and he had these little bags of sand (for throwing ect) so we seid why not?..

the first cuple were ok then they started breaking on the trees
................................................................very funny

The moral of the sotry is, if you cant find anything to shoot, look in someone elses stuff,


Socks work too!

that reminds me of those gay hacky-sack things I shot a month or so ago, the just ruptured open and spewed rubber crap on contact with the tree I was shooting them at.

I mold concrete and water (not concret AND water, one of the other) slugs with pipes cut from the leftover of what I make my barrels with...

Ice slugs are easy to make, and you can make them fast in high quantitys if you have a few molds and a good freezer...
