I make sure the barrel is clean on a factory gun that is new or used that I have bought, or if it is a custom rig with a new Bartlein, Brux, Broughton, Krieger, Lilja, etc... that just came in.
As far as a break-in procedure...I shoot it!
Besides cleaning a barrel when you first get it, I like how a friend of mine put it:
"Since every barrel is an entity unto itself, there is no way to prove that a barrel break-in procedure has any effect on resulting accuracy. Once you shoot it either way, there is no way to return it to brand new and try another way to see if there is a difference. So I. Reality, it's all speculation. A feel good that manufactures give customers because they think they need one. A placebo."
