Exactly NOT!! There is alot of gun experts with more experience than you or I that has alot of those pretty pictures you show, that disagree, including myself.
I've got about 20 years MORE EXPERIENCE than most "experts" alive today. This applies in particular to the ones writing in the gun rags these days.
And I have proven to my own satisfaction, with probably over 250 or so different rifles of different calibers since1952, that this break-in stuff is B.S.! Now, if you want to use up your ammo, barrels, and cleaning supplies that way, have a balland do it!
But just remember Harry Pope's statement - (I assume you know who Harry Pope was) - "More barrels are ruined with a cleaning rod than any other way."
