I got a Douglas factory long chambered 260 barrel that was factory blued. They blued the bore too.

That rifle fouled fast. To break it in, I have to wear the bluing out of the bore. I can't wear it off when it is covered with Copper.

There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. -Ernest Hemingway
The man who makes no mistakes does not usually make anything.-- Edward John Phelps
