I have an old gregorelli/uberti 1851 circa 1962. When I bought the revolver this line that ran the full circumference of the cylinder was present. This is probably old hat to most. My question is, is it a bolt timing issue that can cause this? The line is a very light surface etch (not deep). Look forward to the education guys and Thank you. 👍

It could possibly be from a bolt that's too tall but it's most likely from somebody letting the hammer down from half cock.

Good one, Hawg. That piece has probably been "preowned" a few times. Ring Around the Collar is often self inflicted by the less than prudent.

Hey Hawg and G Dog. Yes,bit is a pre-owned gun. I knew you guys had an explanation. 😊👍 thank you both. So, it sounds like the bolt can ride high though? Thanks , Tim

Like I said it can be but not very likely.

Some of the things that can affect RATC are as mentioned, high bolt and letting the hammer down from half cock, also improper bolt timing/worn hammer cam or bolt leg. The bolt on a Colt should drop in the lead-in unless it's an oval bolt stop like Walker/Whitneyville or 1st Dragoon models. Also Remington NMA/NMN models should drop the bolt about half a bolt width before full engagement.

Probably the condition of the bolt head is as much a culprit as any. If it's the original part, it is probably rounded over on the tall side (locking side) because of wear or attempts at tuning . . . the tall side should have a sharp (90°) edge (but broken). The good thing I see is that it is tracking in the center . . . as it should!! It could also have happened as a bolt spring was failing or a hand spring was breaking.

Morning Cap, Thanks for the input sir. This is a pre-owned and older (1962) 1851 replica. Don't know if that is of any significance. I am hoping it was merely from someone letting the hammer down at half cock position as you described. I need to pay close attention to see if it gets worse. ^j)

Mike, Good morning, I really appreciate your opinion and expertise very much. Would you recommend that I replace the bolt, bolt/spring and hand as a precautionary measure?
Thank you,

Some of those parts will require fitting. The hand definitely will. With it being an older model the bolt may need fitting as well. IMO if it ain't broke don't fix it.

Hawg, thank you sir. It sounds like it could be an expensive venture?

Not so much expensive. You'll likely have to do it yourself. It would be a good lesson in gunsmithing. You would learn exactly how the parts work together. I still wouldn't do it until I had to tho.

Hawg is spot-on here, Tim.
G&U guns are NOT the same as the later Ubertis and while some parts may fit, they likely need to be trimmed and/or fine tuned.
You are a lucky man to have a G&U. They are becoming quite the collector's item these days.
