I did a search on barrel break in procedures and came across the following information from Troy and wondered what you all thought about this. In my search, most people said to use the extensive break in procedure but Troy posted this:
The late Gale McMillen, maker of the famous McMillen rifles and stocks (now called McBros, and run by his sons), claims that the "shoot one, clean, repeat" barrel break-in proceedure was made up by a barrel maker to ensure that his customers would wear their barrels out faster, generating more business. Gale built several world-record match rifles, and advises that his were never "broken in"; they were fired at the range and cleaned at the end of the shooting session. He reported that he had seen lots of ruined barrels as a result of over-enthusiastic cleaning, but none from "failure to break in". I have no cause to doubt Mr. McMillen, and my match rifles were not "broken in" and I still get tiny groups from them. A minor exception: chromed bores should have at least 200 rounds fired in them before cleaning with a brush (patches are OK), which helps polish the chrome lining. That's the only real break-in requirement. -Troy

What of this? Am I going to throw away my time and my money by doing the break in that people on here say is necessary?

Boy, has this been argued adinfinitum amongst we hipower types. If you ask four of us you'll get five opinions, at least. My personal experience is that the proceedure works. I've done seven barrels now, and on one occasion I could document the groups gradually tightening as the afternoon wore on....and it DOES make for a long afternoon. I'm coming down on the side of those who do it, but I'll throw no stones at those who don't.

Fire 1 round, swab bore with aqua regia. Repeat for 20 rounds.

Do you use the brass brush during a "break in", or just a coated patch? (Again, if it is even really necessary.)

Thanks for the reply, Waldo. [:)] Has there really been any [b]substantial[/b] evidence that "breaking in" a barrel improves accuracy? Given two identical rifles, one just fired, and the other using the extensive "break in" procedure. I'd be interested to know how much of an "improvement" all that work accomplished,. . . . .if any!
