Thankyou very much for that. I will take my recently aquired ROA out to the range next time. I am looking forward to it. Just got to get the oxyoke wonder wads & a powder measure first for loading the cylinder. Will the Hornaday .457 balls be a tight fit and stay in the chamber on their own? They don't sometimes roll out do they whilst the pistol is inverted? Thankyou for the advice. G.
