Maybe, but that's how you start with reamers if you have no one there to instruct you. You move slow and careful and the end result is the same. I had an M1icon rifle come to me that had a perfect barrel, except someone had thought it too tight and overdone it a couple turns. New brass showed a separation line...no issue with military ammo and not reloading but that's not here in Canadaicon.

That also brings out the bits. You could have used brake cleaner for the cleaner, it has pressure and a long tube to reach inside. Go muzzle down and it blows everything out and leaves it dry for testing. Next time... Anyway, well done. By the way, it might still want a touch of polishing.
