My 1970 remington 1858 lyman/uberti has the # 415 stamped on the frame, cylinder, ram and marked on the grips. I find the cylinder takes pietta nipples, the chambers run .378 tapering down to .376. Not having any .380 balls I swapped in the cylinder from my pietta 36. it seemed to function fine and there were no problems firing at the range, except it shoots about 5” high at 20 yds. Is it unusual that the uberti and pietta cyl's can be swapped?
