357mag at the moment (Uberti do the low wall in this calibre)

I don't want to mess around with Black Powder therefore due to the range velocity limit (2150fps) I'm also limited by my calibrate choices to essentially 357mag, 44spl, 44-40 or 38-55

Ideally I don't want to acquire equipment for yet another calibre therefore, if it's viable, 357mag fits the bill. However if more suitable 44spl might also although this would require adjusting my 44mag set up to make rounds.

Hopefully that logic makes sense.
