I was hoping for more of an explanation on this
It would appear to be the superior technique, and I cannot imagine why this method is discouraged?
I'm not down on it, I'm just really curious and would like to learn more
pipe cutter has rollers that make it track straight... on pipe that has parallel walls. Most shotgun barrels taper. So it's gonna walk around doing a very gradual spiral. It would probably work but the cut won't be perfect.
I would lay out the line with masking tape to try and get it close then cut it with hacksaw and true it up with a file.
The right way to do this is on a lathe
