thanks guys, i made a new gun with a steel combustion chamber and a pvc barrel. the ignitor is a lantern ignitor. it works though! and thanks again guys

For my Physics project we need to build something that will launch something 100 yards. So I decided to build a spud gun. My dad and I built it out of ABS and i was wondering is ABS good enough? Will the ABS withstand the pressure? It is a combustion cannon, the chamber is 3" and the barrel is 1.5"....
