All barrels are chambered with reamers that result in the “marks” that pick up copper from the jacket until they get “ironed” out. Given that most “factory” barrels are not lapped, it would be reasonable to assume they would pick up even more copper than a lapped aftermarket barrel. I would do a BI on a virgin factory barrel.
