It is a bullet rifle, not a round ball gun.
Both of my barrels with my Don Brown rifles had/have the crown finished that way. My first one, a buddy that was fitting the sights cut the barrel off flush to remove it thinking that it would give better accuracy. The second rifle was not cut down and still has the same crown finish. I cant say which rifle shoots better as they both give acceptable accuracy. Neither one is difficult to load.
As I stated on a different forum, this rifle could be a long range shooter, but with the ramrod the style is more for hunting, not for target work. Also the rear sight is not tall enough for 1,000 yards, might get you to 500 yards.
