But when you look down the bores, the view is quite horrid. There are pits, tool marks, annular rings, and blemishes galore. And yet not only do both Scouts shoot very well, they don’t pick up copper fouling, which by rights they should. I put the .308 through the standard rifle break-in process, but did not do so with the 5.56, and it made no difference. Both are a snap to clean.
