Also handy to inspect the upper end components of aircraft & automotive enginesAbsolutely, I got this for one purpose, to keep track of throat erosion on an unmentionable new fangled bang stick.

The You Tube link inserted is a good one. The only thing I do different is to pull the breech plug and clamp the barrel in a padded vise. I have also poured a lead lapping plug around a steel patch rod tip and used valve grinding compound to lap the barrel, that way I get the lands and groves polished at the same time. I understand not everyone has the equipment or ability to pull the breech or pour a lead lap. But I like to "refresh" the whole bore and yes it's labor intensive.Agree. I would use a piece of scotch brite and just insert it down over the bad spot down by the breech and concentrate back and forth over that one spot to see if you can smooth down the edges of the gashes.
