Everybody that has ever read many of my posts knows I'm an accuracy freak. I also happen to be ex competition shooter and gunsmith for 26+ years. I can only tell you what I do to break in a new barrel. Most think it's extreme but has proven its worth over the years. After hand lapping the bore and cleaning pryor to first shot,I clean after every shot for first 10 shots,after that,I clean after every 2-3 shots for about 20-30 rounds, depending on caliber/cartridge/etc.That consists of my own personal routine. Stay away from tubbs firelapping as I've replaced barrels where it had been used (abused?) and it ruint barrel. Always lap by hand and you won't go wrong.
