Was playing with my Uberti 1858 and discovered that one out of three cylinders has a timing problem.
I have 2 OEM cylinders and 1 R&D .45 ACP.
One OEM and the R&D work perfectly.
The other OEM doesn't.
It simply won't hit TDC and lock unless I either "forcefully" cock the hammer or manually give it a near 3mm turn.
Most distressing is that the hammert will still rom on the cap even if the cylinder is not fully locked.
I can't see any difference in the feed pawl cuts, so I'm stumped.
Hate to throw away an OEM cylinder if I don't have to....

Hopefully steve young will soon give you an expert opinion.
Having spare cylinders work without fitting/timing seems to be the exception rather than the rule. None of the ones I've tried have worked and I have tried several. I have revolvers (19) made by pietta, uberti, and a.s.m. and have bought three or four spare cylinders over the years and none have worked and I don't have the patience to make them work.
B.T.W. the remington is the only one that a spare cylinder makes sense, the other designs are not quite tactical reload friendly.

I think you're looking in the wrong place... Here's an idea...
Check the dimensions of the bolt-locking-notches on that problem cylinder -- and I suspect you'll find the answer there! They could be slightly undersized, maybe the lead-in angle is wrong, or perhaps there is a burr on each ("forcing" that cylinder to lock up could easily displace metal).
Don't mess with the locking bolt itself, as we know that's OK from the other 2 cylinders.

That gives me the willies for sure!
Instead of tossing it, why not see if it would work with another Uberti 1858? If it does, you could sell it - at least partially fund the next cylinder.
I had one like that years ago and offered it free here if the taker would pay the postage. I think it bounced once or twice before landing with someone who's gun it worked with.
