He recalled noticing that a lot of the barrels looked rough through a bore scoped, and listed some things to look for in a barrel that might point one in the direction of electropolishing to smooth out rough spots and improve accuracy drastically. The author also mentioned that even though some people utilize fire lapping to replace normal break in, that he has never tried it and would be hesitant to do so because “fire lapping will obviously move the throat forward more than a conventional 10 shot break-in and recommend that
