For all of you who havent tried this... i suggest you do... it works with the same principle as a shotgun shell... except for your launcher. spent caulk tubes fit perfectly in the barrel as a wad. just grab a bunch out of a construction site dumpster. cut of the tip and halfway down the tube, then cut slits down the side. you can easily make a shell out of a couple fittings, slide in the wad, and whatever you wanna shoot. heres a pic of mine.

"Not all barrels are created equally"

With that said, perhaps you should tell us what size and type barrels these wads fit in. Also, are these wads reusable? Do you have to clean them up before using them? Why not just use the entire thing as one piece of ammo?

They will fit in 2" Scedule 40 PVC, I would imagine that they would also fit in 2" copper if you have that. The whole caulk tube also makes excellent ammo because when empty they are slightly front heavy so they fly without tumbling. The wind does have quite the effect on them though.

Does this count, or is it just a sabot?

he is right... they fit in 2" barrels... slightly too small without the sides slit... they give a tight seal... and it varies on reusability... sometimes they crack... also you gotta find em
