Anyone else thinks this looks like crap?

Im talking about the 7 o clock to midnight of the muzzle. Its so out of round, its practically oval...i don't even know how something like this could be drilled...how does something like this even happen at the factory. I have never seen a drill capable of drilling an oval!...i need to know what went wrong at least before i can figure out if it can be fixed, honestly ordering a new barrel seems like a crapshoot if this is what ended up from their manufacturing process...project weather is coming soon, and work will be winding down a bit. Would like to make improvements on this gun as i am really fond of it...i just don't see how it is possible that the entire interior of the barrel follows this shape. Thats not how drill bits work! What is going on here?

It does look lopsided, but how does it shoot? If you don't like the appearance, I suggest you crown it. It does not look like there is much if any there now. (Crown)

its a 5 minute job to recrown and tru up at your local machinist shop

Yeah, thats what I'm getting at...i think the solution is to trim back the muzzle an 8th or 16th inch. There is a loading lever latch to worry about so i can't go too far back...the next loading lever assembly available in size is for a 5" barrel and i want to keep it at 7.5"...

Whether it originally came from factory defective, muzzle/ramrod wear, or contact with a rock at some point while squatting down along the river fishing, i posted this thinking a crown job was in order. But i am not sure how to go about it with hand tools...was hoping one of these guys with all the good jokes would have some experience with it and provide some insight on the process.

 

[golden sky]

strip it down and post a pic of the full assembly, it might fit in a large 4 jaw chuck on an engine lathe...

Very hard for me to form an opinion. As a picture showing the muzzle of a barrel to show out of roundness would need the camera dead center with the bore and not canted. Not sure if the picture truly represents the condition. But if it shoots great then what the heck, show the target and brag about your skills in shooting such a weapon.

My rather snarky post, now that I reread, it was a smart a.. reply, apologies to the Op. was an attempt at pointing that out.

Im amazed at the accuracy of these guns. I own north of 20 of them in various models. Priced to sell at sometimes half the price of modern revolvers they can run with the best in the accuracy department. Yet we read complaint after complaint on fit and finish.

I once had a Pietta revolver that was, in my opinion not theirs, mechanically defective. Not much problem getting a refund.

Oh, do sent it back before you mess around with it

If you choose to try and crown it yourself, versus go back to factory (if possible) this is all I use below. No big deal for me. A die hard machinist will most likely have a hiccup over my suggestion as it is not perfect, only as good as your ability.

How does it work?

 

[Whitworth]

Put a larger caliber lead ball on the muzzle and hammer it partially into the muzzle. Tap it out from the breech end and examine it see the true shape of the muzzle.

 

[Rudall]

The OP has shot this pistol thousands of times and is only worrying about this problem now?

 

[sheriff john]

I had a cheap brass bullet mold one time that cast out-of-round conicals but the round ball hole was ok. Maybe it was meant for your gun. It went "bye-bye" at a gunshow.

 

[rdane]

If you have used it as much as you say, then why complain about now?

 

[Coinneach]

Elmer's and some bailing wire will fix just about anything .

You must be an Aussie "She'll be right mate" !

 

[Brokennock]

What the heck is wrong with you people?
If you don't have something helpful to add, why don't you just shut it?!

The man asked for people's opinions.
Maybe he was hoping to affirm his suspicions, or have someone give him different idea. Maybe it is something that has been nagging at him for a while and he finally decided to ask about it.

You must be the type of folks who speak just to hear their own voice, with nothing to say worth listening to.

 

[Brokennock]

In topics/discussions where it has come up, I have always been against the "lead box." But I think I've found my 1st three to go in it within this one topic.

 

[.36Rooster]

I dont know, Brokennock.
All I got to say is that it's the internet, i guess; And for the several people who've commented despite not having any useful insight on muzzle crowning, then i can't really help them keep from making themselves look bad...this is a thread asking for advice from people with technical experience in muzzle crowning issues. And as far as im concerned, all these wisecracks, and clever remarks are being made in the absence of any actual knowledge.

Anyways, I am just going to get on brownells, and browse through their hand tools, and see if I can find anything I can buy and figure out how to use for myself. Its my gun.

I have tuned up three Pietta 1858s. All had micky mouse uncrowned muzzles. The best way to crown any barrel is with a lathe. Center it, make sure the bore it pointing right at the tailstock. Take light cuts. I use a sickle shaped cutter to make a progressive angle crown. Yes it can be done with a piloted cutter. You will need a pilot of the exact size though. Hacksaw, file and abrasive ball jobs are makeshift. I am not saying it won't work, just that there is no guarantee that the crown is dead straight to the bore. IF that was the only option, I'd stick with the Pietta "crown".

 

[Dude]

Before removing any of the barrel's length, why not crown it as it is? That should make it look good.

Are you saying it's not particularly accurate at 25 yards?

It's easy enough to remove the cylinder, shine a light through it and give us a photo of what you see.

Hi Rooster, There's nothing wrong with Oval bores so long as there is No rifling in the bore apart from the twist in the Oval.. Charles Lancaster(London 1815----> made lots of them . Shot quite well out to 1000yds. They where of course made on purpose that way in UK. OLD DOG

Brownell's has what you need. Look for rifle/handgun muzzle & cylinder facing & chamfering tools. They turn by hand & you just get the pilot to match whatever bore diameter you have. They come in both 90 degree to square up muzzle & 45 degree cutters to give a recessed crown.
