Was at the range today and a friend had one of the Uberti made Cimmaron copies of the 1872 Colts open top frame .45 Schofield Cal. revolvers.
The owner was shooting Black Hills Arms factory "Cowboy" loads, on about the 18th round two of the chambers came apart! split the cylinder from front to back where the bolt lock cuts were made.......these cuts were so deep that the metal at the point of rupture looked like foil........ the case in the chamber under the hammer was loose in the chamber and the primer was no different in appearance than the others in the cylinder....no pressure signs at all.....except the top of two chambers lying about three feet away on the concrete. I don't know if all these revolvers are subject to the same problem....but if you have one.......be cautious and wear protection.........the next one that blows may just hurt someone!

Why would this happen? Bad metal? Cimarron needs this brought to their attention if they don't want to be in court. Is this one of those Mason conversions? I have seriously thought about buying one of them.

Tony, it is a copy of Colts first catridge revolver....the 1872, a very pretty and smooth handling firearm......but for some reason Uberti/Cimmaron decided to use the 1851 frame instead of building on the 1860 frame as were the original revolvers.....the 1851 being .36Cal. originally....the cylinder just does NOT have enough room to put 6 .45 Cal. catridges. IF the revolver had been a 5 shot....I don't believe this problem would have came to be as the 5 shot cylinder would have the bolt cuts BETWEEN the chambers instead of dead center of the thinnest part of the web between the chambers.
The revolver is on the way back to Cimmaron.

Pretty stout for cowboy loads, wouldn't you say? Yeah, I can see where .45 in an 1851 would make metal too thin.
