After reviewing several posts regarding the "Break In" period, I have questions. How many rounds through the new gun for an adequate break in, without hitting the point where it actually is wearing out? I understand it's not an exact thing and there is probably disagreement among knowledgable people, and to an extent each gun and the way it's maintained. At what point (general range) should I feel I have hit the optimum break in without loosing service life? Comments wecome!
