Nerf Rifle (the not-so-mini cannon)

This turned out surprisingly well for something I built out of sheer boredom..
The nerf barrel was from a project that never really lifted off. It's a length of 1/2" sched40 pvc (this is probably the closest to a perfect C:B I've ever got got a mini) epoxied to a cap that fit perfectly on the chamber.
I cannibalized "C/B Nightmare" for the igniter, that worked nicely. My only real beef with this thing is that the electrical tape is all tacky (from a really old roll.)

Next step is burst-disk.

UPDATE: Got the non-tacky tape and tried out burst disk (1 layer plastic shopping bag,) and its great! You can;t even see the Nerf dart as it leaves the barrel =DDD

New pictures too.

I dont think that plastic bag would work so well as a burst disk when it's used in one layer...
Try multiple layers for a BOOM in preformance

How is it ridiculous? Like, the barrel is too big? Or is the chamber too big (I'd choose this side. The barrel could be a bit longer...)

I've measured it w/ water myself, its nowhere near optimum (I didn;t have a longer pipe laying around)

the barrel is long, not that there is anything too bad about that
