    How much worse would the barrel of a rifle be if the crown was taken off?

    From what I understand the crown of a rifle is supposed to be even on all sides so the projectile will be centered and not be thrown to one side or the other. Now, If the crown is in good shape I see no reason to remove it.

    I'm not asking about a crown that's in good shape, just a hypothetical question on recur owning firearms.

    It wouldn't be any worse as long as the muzzle was cleanly faced off perpendicular to the bore line, and no burrs remained. But one little bump or ding on the muzzle afterward, and all bets are off. A big part of the crowns job is to protect the end of the bore and rifling.

    If I were to leave the saw cut end of this barrel blank as-is, it wouldn't shoot worth a hoot!

    Exactly. The reason crowns are rounded and, usually, are not flat is because this protects the crown.

    My rifles with a target crown are not rounded- they are slightly dished in, with straight lines. But again, it is to insure that as gasses are released when the bullet leaves the barrel- they are released evenly, and do not push the bullet to one side or the other. Dan Wesson revolvers typically have a pretty flat "crown"- due to the unusual barrel design.

    A crown is very important for a rifle to shoot accurately. I had a rifle that shot 3 to 4 inch groups at 100 yards and after I recrowned the barrel it shot the first three rounds under and inch at 100 yards. In my eyes that's a huge difference.

    I agree, I think that's a huge difference too.
