1858 Conversion cylinder to barrel clearance

[Wagon Box Willy]

Howdy Folks,

I just purchased a pair of Uberti 1858 Factory conversions and they need some work for BP shooting.

The one I measured measured has a cylinder to forcing cone clearance of .0055 and after a cylinder full of BP rounds it binds there.

My 1875's are .009

Thanks.

Another issue with the guns is that the firing pin plate blocks view of theloaded cylinder so it's going to be a pain to use at CAS matches.
