Break in ???

[Variable]

I see a whole new line of thinking here
we can sell copper paste to apply to bullets to fill those ugly cracks and dips in the barrel .
the process will create a better seal and increase velocity and accuracy
IE: Moly, Otis lifeliner and several other products in the past

Perhaps for a small fee I could allow folks to remove the copper from my barrels and allow it to be chemically rendered for use in there own firearms. That way I could give back to the community!
