Based on having done this break-in routine to several rifles, I now think it' s just a waste of my time. Instead, I simply take a new rifle, clean the barrel of any residue left at the factory and then go shoot it. I give it a thorough cleaning after about every 20 rounds.

I' d like someone to prove that this break-in nonsense results in a more accurate rifle. It hasn' t for me. The two most accurate rifles I own were not " broken in" . The late Gale McMillan, who made match barrels for a living, thought it was nonsense. The guys at Shilen think it' s no big deal either.

If someone wants to do it, that' s fine with me. However, if they think it' s going to result in a rifle that' s more accurate, they' re fooling themselves. It will reduce copper fouling quicker, but that' s about it.
