This is slightly off the beaten track, but is this scraping and jewelling truly effective or is this just part of the gun-culture mystique? I can't see why making something rougher is a good way to make something smoother. I don't see this being done to bearings for instance.

I apologize for side tracking a little here, but this has always mystified me. Makes no sense at all that I can see.
