I've not much experience at conical shooting in percussion revolvers and in our recent discussion on stepped chambers I began to rethink this question I've had for some time (about the need for conicals to shave a lead ring) as to the differences between ball shooting and conical use.
Balls will self center under any ram face profile but this is not necessarily the case with conicals and especially conicals with square bases. Shaving a perfect lead ring to insure base seal is not a guarantee on bullets and this is where the tapered chamber and heeled bullet profile would demonstrate an advantage in my opinion. My educated guess is that the gradual taper would probably promote better alignment accuracy and gas seal than a step that I previous thought an advantage. The steps I have cut have a 45 degree transition taper but the Uberti taper is much more gradual and I think to be preferred.
The chamber mouths still need to be opened to groove diameter but the chamber cut of more gradual taper like Uberti apparently does. A taper reamer would need to be fabricated and I haven't made one in a few years and need another project like a tax audit but I'm approaching the curiosity level that may pull the trigger on this deal if I can ever get caught up on the others.
The easier approach will be to fully ring out the Uberti chamber taper and see how it pans out before embarking on a new reamer make.
