Crowning the muzzle of a smoothbore?

[mark_fare]

Hello All,
There is alot of discussion on this forum of crowning ML rifle barrels. Is it applicable to smoothbores? I have a Pedersoli Brown Bess and the crowning on the muzzle is a little sharp and it shaves off material from both my delrin and hickory range rods. Would it be prudent to smooth the crown so this doesn't happen anymore?

If it is that sharp, I would say yes. You can "break" it with just emery cloth under the pad of your thumb and gentle pressure while you twirl your hand around the muzzle. It don't grow back so don't get all gorilla on it. You'll only need to smooth it - not remove a lot of metal.

Done it lots of times.
My method is to rotate not only the finger or thumb but also while doing so walk steadily around the upright gun. It avoids favouring one area!

I believe that is an old (eighteenth century) telescope making technique.

Was you accuracy affected?

No, not at all. The last three shots on the upper black, 1.5" at 50 yds.
