FYI on new Uberti Conversions

[Fox Creek Kid]

I bought a NIB Uberti factory '58 conversion over a month ago and quickly sold it to a buddy who simply had to have it. Well, he's $100 poorer now as the breech face peened (actually caved in!) on the conversion face from less than 100 BP rounds!! $100 poorer as he sent it off to a top notch CAS 'smith who machined a beautiful hardened recoil plate into the conversion ring. Just an FYI.

So what you're describing is how you screwed a friend. . .

Actually, I didn't want to sell it but he whined & cajoled and I relented. Since he'd done favors for me I let him "lowball" me on price but Providence saw otherwise!

This is troubling. I expect better from Uberti.

I hope my '75 holds up. A different gun, I know. But the same steels?

Are you talking recoil shield?
What is the "Breech Face? Forcing  Cone? Never heard the term in connection to BP weapons. What exactly "Peened(the firing pin hole? If , indeed it is the forcing cone at the breech, then it sounds like the chambers do not align with the bore.

Charlie, the breech face is the entire area directly behind the cylinder. The area where the free floating firing pin is on this particular conversion (the face of the conversion plate) was the area that peened severely. So much so that the firing pin froze. Colt & USFA have hardened recoil plates on their revolvers ( as well as S & W and Ruger) through which the firing pin passes. I have had to have recoil plates machined into two Uberti Open Tops. Beacuse revolvers need "play" in their headspace in order to revolver the cylinder there is damage from the rear of the cartridge case slamming into the breech face over time. In revolvers with soft steel, such as Italian one, this is sometimes rather quick.

Got it.
Breechface = recoil shields or plates. I just put one back in an Old Remy conversion.
Was that gun backing out the primers as well? that is the only thing I can figure that would do it, as the brass is forced back into the recoil shield (hence the base imprint around the firing pin hole thru the bluing or finsih after a several shots.
