Man, that is pretty awesome. I tried making a piston like that but it leaked too much. Does yours leak at all?

Did you just spin the piston around on the drill press? What is the made of?

Cut some holes at the end of the barrel so it looks like a muzzle break.

Verry nice

Considering the muzzle is inside the chamber, I don't think that would be the brightest of ideas :roll:

Very nice. Good job :thumbup:. One question though, did you say it can shoot DIRT through wood. Or rather is it the cup full of dirt going through wood. Regardless, the gun sounds beastly.

hehe nice gun..who fires dirt out of there gun other than this guy..its a first...i here by pronounce u to have found the ghettoist of ammos...

anyway yea my first piston leaked out the barrel a bit to so when i went to shoot water out of it i had a sabot that was perfect in the barrel it was a peice of foam i rammed in there..all of the sudden it started building pressure in the barrel because it was blocking all air and then as i was pouring the water down the barrel the foam peice shot out at me...now it didnt hurt because it was foam but it scared the shat out of me because it was loud as hell...


^^^ dont read if u dont like randomness...
