yes, it is kind of like a PVC vs ABS form now, and i am personally with ABS, and if coke bottles don't blow up at 100 psi, why would ABS. it is just a matter of if you can get pressure rated pipes.

edit: after seeing that pop bottle blow up on mythbusters, i would not want to be near a pop bottle when it "blew up"

Yeah it seems that every time this issue comes up it turns into a debate on what it can or cant do. lets just agree to disagree.
How ever I do you high pressure rated PVC in my cannons, It's expencive but its the added insurance of knowing that it will be fine.

The gun failed at the elbow not the dwv bell reducer.hmm and I don't believe they have DWV in such small sizes.

I wish I could get tiny DWV....
Kind of Off-Topic, let's just say don't use DWV PVC or ABS or any unrated pipe in cannons. Sums up the 5 page topic quite well, don't you think?

As a precaution I usually slide a dual layered piece of cargo pants leg over my fittings (I make big guns so it fits snugly) then zip tie around the fittings to hold the cloth in place. I occasionally use dwv fittings in 100psi applications, however anyone with experience can tell if a part is solid core, and when a fitting is just too thin. I will sometimes use my calipers to determine this. I have only had a part fail once (3" pvc-pw endcap 100psi, and it was 4 yrs ago) and all of the shrapnel was held by the cargo pants.

I only leave the pipe itself exposed, as I'm never going to get past it's rating.

That doesn't work, if you're stupid enough to actually think that cargo pants will protect you from high velocity shards of sharp plastic, then I dont think you should be allowed to make a spudgun at all.

*waits for someone to post that video I saw a long time ago where they wrapped cannons in duct tape and tested them, and did all kinds of tests and they all failed*
