But if your serious, it may serve the "end purpose", if you care nothing about "end accuracy".
Take an old or wore out barrel, and push a tight patch or slug down it. Then weld a bead down it a couple inches and push the patch/slug down it again and you will feel the answer.
Lay it next to a square both before and after, and you will see some answer as well.
