Should a BP revolver barrel have a crown? I'm looking at this 1851 Navy and the barrel was cut square and it doesn't even look like the muzzle was de-burred, let alone crowned.
BP barrel and crown ?'s

C&B muzzels are generally just cut square. No crown.

Fingers, why is that?

This is why kwhi43 doesn't believe in crowns:

I have crowned several and got better groups.

Fingers, is there a reason they just cut them square? Was the knowledge just not there yet, about muzzle crowning?
Arcticap, what in the world is that a picture of?

That is a picture of a chunk gun muzzle. The four holes are for a false muzzle used to prevent damage to the muzzle during loading. These guns are used for very, very accurate bench rest match shooting. His point is that the people who shoot these guns, with incredible accuracy, do not crown their muzzles.

discussed above
As for the false muzzle HOGWASH. you forgot to say he puts a feather in his hat too. so if you dont put a feather in yours you wont shoot good. Every gun is different. There are purposes for a proper crown. You can believe in crows or not dosent matter. The most important thing to remember about crowns is they are there to keep you consistant

That picture actually is of my Flintlock pistol.
The bench shooters at Friendship would love to know that they are just wasting their time with their False Muzzles. I think if someone
feels that strong about something, they should go to the Nationals and tell them about it. I would. Oh, I forgot, were dealing with
arm chair experts here.

Some people swear by crowning barrels, some don't. Just like some people like Ginger & some Mary Ann. On a cap & ball revolver, it really isn't necessary cause they aren't loaded from the muzzle so there is little chance of creating a burr on the lands that might cause an accuracy problem and gun makers didn't have to add a step that would increase costs.

you are kidding right. We all know its about Mary Ann

Of course it's about Mary Ann. 
But; I realize there are some misguded souls out there that appreciate Ginger's attributes more than the goddesses - er, I mean Mary Anns.

Scrat, thanks again! It seems Google was right this time. Well, at least right about so many differing opinions. Oh yeah, Mary Ann any day of the week. Except for now. She is old and got busted for having some of those "left handed" cigarettes.

Fingers, ok, I'm traking now. As long as the barrel is cut square to the bore and remains so, with no dings or burrs, it should be good to go?
A flat muzzle is the most accurate. All my Bench rest rifles have heavy barrels with flat ground muzzles. They were made that way but I can grind my own if they get a problem.
Reason is that any other type is totally dependent of the cutter or stone being exactly centered with the bore which is almost imposable to achieve.
If a beveled cut at end of rifling isn't cut perfect then accuracy goes away.
The cutter of a flat muzzle can be off center by a fraction of a thousandth or even more and still the muzzle surface will be exactly perpendicular with the bore.
Crowns are put on sporting barrels to help protect the ends of the rifling from being hit and damaged.
First one in drawing is a recessed muzzle. The same as a flat one but with some protection from damage to ends of rifling. second is a crowned muzzle. as before it protects the rifling but is less accurate because of centering the cutting process.
And the last is just a beveled muzzle which has the same inaccuracy problems as the crowned one.

Winchester Model 1873 rifles usually did not have a crowned barrel. Here is a photo of the muzzles of several. The saddle ring carbine all the way on the right may be crowned. Modern made Uberti 1873 replicas do not have crowned barrels either.
I have an original Winchester Model 1892, made in 1894, and a Marlin Model 1894, made in 1895. Neither of them has a crown on the barrel. I have another Winchester Model 1892 made in 1918. This one is a saddle ring carbine and the barrel is crowned. Not really crowned like we are used to seeing today, just kind of smoothed over a bit, inside and out.
All the replica C&B revolvers I own do not have crowned barrels.
The first C&B revolver I ever bought, a Navy Arms brass framed 44 caliber 'Navy' that I bought in 1968 was not crowned either. And really close inspection showed that it was not cut square across. It was imperfect, there was a slight angle.

Exactly. It's not some magic tweek to improve accuracy. It helps maintain accuracy by keeping small dings away from the bore. Simple as that.

Would it not be technically accurate to say that all barrels are crowned but just that some are square crowned while others are bevel or round crowned? I thought that by definition that the end of the barrel is the crown regardless of actual shape used or not used.
A crown is a rounded top of something, like a hill or the top of your head. To crown a muzzle is to round its flat area.
The end of a gun barrel where the bullet exits is called the Muzzle. Could be a flat muzzle, a recessed muzzle, recessed muzzle with a chamfer, a crowned muzzle or a chamfered muzzle.
