I'm glad I asked this question now, I've never thought alot about breaking in a barrel, there's been some really good information presented. Guess that's why i enjoy firearms so much, just when I think I know it all, I realize how little I do know and how readily, "knowledgeable" folks will take an opportunity to offer real help and facts. Thanks for the information Gatekeeper and others, it's been worth the reading and research. Since first asking, a friend has told me about a "Dewey" method. It requires running wet patches and brush after every shot. "Tom" says he does his competion rifles this way. when a win is a difference between an "X" and a "10", it's been worth the effort, he's been a state champion several times and has done very well at nat'l levels. If it's shoes, cars, even compostie aircraft parts, most stuff needs to be "used" a little to get the best out of it. sometimes if something isn't broke in, it breaks from being too stiff, right. Sometimes "sharp", newly machined metal parts, need to be smoothed just a hair. Thanks for replys.
