Interesting thread.
I recently observed, over several range sessions, a shooter "breaking" in a custom drop-in 10/22 barrel with an aggressive regimen typical for centerfire tubes. Shoot five, scrub with a brush and a solvent designed for centerfires, repeat endlessly. He did this religiously because that was how the barrel manufacturer had said to do it.
An interesting psychological phenomenon is how some shooters will latch on to a guru, and treat that person's dicta like the Sermon on the Mount. You can't budge them or even cause them to question it. Another high roller at our range has a guru back east who he pays an hourly consulting fee for his advice on accuracy.
Oh to have such credibility!
