The best barrel I ever bought was carbide swaged and did not require any special break-in to be butter smooth. It came that way. Factory barrels - some had more chatter and machine marks that it took thousands of rounds to smooth them out . . . and by then the throat was eroded.

One of the most accurate barrels I have shot (still have it) was pitted before I bought it. Takes a long time too clean (clear cotton patches), but shoots well whether it is clean or not.

Look at the groups, not the barrel. ;-)
