I'm not sure if anyone has tried this yet but we did (a friend and I). We put 9 3/4" cpvc barrels inside 2' of 3" pvc. The barrels are glued with Great Stuff which stands true to its name. I don't have a chrony but I'm guessing it goes around 300 to 350ish fps. Check it out.

This isn't from the shotgun barrel but a regular 1.5" barrel. What you see here is a mold of the bark on a tree. The hole in it was from a nail that was in the tree and it poked through.

This is 1/4" plywood. There are 18 pb shots on there from about 30 feet away. They spread out very nicely. The hole is from a duct tape rock.

What exactly would you call this gun? It's not really a true shot gun but it shoots multiple shots at one time.

It's a Volley Gun, much like the French Mitrailleuse :wink:

Look at the randomness of the spread, I’m guessing he didn’t.

Nice volley gun, you need to adjust the spread so that it’s wider, basically so that it puts all the rounds in a line.
But other than that nice work, cut the foam back away from the muzzles that should improve accuracy.
Call me "Judge", it's easier to type.

Great looking cannon there. I love the multi-chambered shotgun attachment, very creative. Keep up the good work!
