I have been buying, selling, trading and shooting new & used rifles and pistols for about 50 years. I went through at least 40 years of this time without ever having heard of this "breaking in" stuff. I think it is a crock.
Maybe if you are shooting a benchrest rifle, maybe it is a good idea. But for a hunting weapon?? NUTS!!
(Reminds me of a friend in Japan right after WWII who bought a Japanese sword (wakizashi) that was rusted and needed to be polished and resharpened. He took it to the swordsmith to have the job done. He was asked if he just wanted a "mechanical job", or was he "planning to use it??" He asked what the difference was. Well, a simple polishing and resharpening job would take a mere two weeks. But the "full treatment", for a sword that would be used for its' intended purpose, would require six months which included a number of trips to a local Buddist Temple where the proper benedictions would be given after each step in the restoration job! Otherwise, it would not be serviceable.)
