i built this a couple years ago now but only just started using syringe fuelling and a piezo to ignite it. roughly 1.2m barrel, 7.6L chamber and 5.3L Barrel. Ive been shooting 600ml coke bottles filled with water wrapped in a bit of electrical tape but i just discovered a wine bottle fits the barrel pretty well so il have to try it. The recoil left an alright bruise aswell.

Yay for syringe metering! Ghetto but looks fun, you have to film the wine bottle - from a safe distance, of course ;)
