I've always wanted to do something with copper, but at $5 a foot for 1/2" type M, it's just too damn pricey for me.

Yes it is, it's a co-axial (barrel concentric with the chamber) with a piston valve, look here to see how it works.

I'll have to look for that next time I'm at the store. I always hate how epoxy is so brittle pieces always get chipped off.

Jon_89: The shots were fired from ~2 inches away.

would you mind posting the gun you use at this pressure? Ive never seen any of your work and it sounds very good.

Actually, now you mention it, I realise I haven't posted any of my cannons in months.
I really should I suppose, so I'll get that sorted then.
