Terry,
I got this piece of bar with a big hole in the middle and it's made of steel, brand new, none of those swirly marks on the inside like my other barrels have, I s'pose it's a smooth bore. At least it looks purty smooth inside. Maybe it's just a shined up piece of water pipe and I got ripped off, what do you think? Maybe I should make a harpoon out of it? Or me, you and Roger could get together when we all get them done and see who's (or who) shoots the best.
Bill
