Brought the new-to-me .38 Special Uberti/Cimarron 1866 home -- yippie, skippy!!
Lee's 358-158 RNFN sized to .358" is a wee bit fat to reliably chamber, and their 358-158 SWC is a definite no-go, as it gets hung up on the squared-off chamber the same as in the Rossi 92/EMF Hartford. Sierra's 158-grain JHC feed, chamber and eject smoothly 100 percent of the time, so will load some up for Monday's range session.
The original owner replaced the loading gate (Uberti calls it a ladle -- really weird), because the tab on the back of it was bent and created feeding problems, but I don't know if it's Uberti, or aftermarket. In the process of disassembly/re-assembly, he, or worse yet his gunsmith, buggered the lever screw head and the magazine tube plug.
Bore is blindingly bright and rifling sharp, though it was a mite dirty, and Mother's Mag Polish really spiffed up all the brass work.
All-in-all, my lever-action rifle soul is about as happy as can be.
