Somewhat out of character for me, I really didn't research it too much. I don't know if the process has any real effect on accuracy or velocity. I knew that I wanted the barrel to be black, and figured the process wasn't too much more expensive than getting it blasted and coated. Knowing that the process hardens the metal, I tried to simulate break-in via the bore polishing, as some people seem to think that a break-in (via shooting) is best beforehand. Others suggest that the barrel should be clean and unfired for the treatment. I don't know which is best, so I sorta split the difference. I'm encouraged by the results so far.
