Thx Mike. I have an RB chambered in the .43 Egyptian. It is also the off spring of the 44-77 target round later Bison buster. The Egyptians faltered on the order to Remington. These were actually sold to the French.
I picked the RB up down in Mexico many years ago. Like you I modified the sights. I do however prefer the Sharps Rifle. Great video thanks again.
