Period correct '74 Sharps Buffalo Rifles?

[Kurt]

That will do a fine job behind 75 gr of 2F OE or 73 gr of 3F OE
both of those loads keep 5 shots under three inches at 200 yards using the ladder sights and Stephen's Hartford cloned front sight. At 130 yards you can cover the 5 holes with a 1/2 dollar using the barrel sights.
Some day I might put a tang sight on this rifle so I have windage adjustment and use it for silhouettes.
The bullet below is what Steve made for me from a bullet I turned down on a lathe that I copies from a original and he hit it on the head. But later I made a flat base plug for the mould.
With that .485 gr bullet in the picture and the 75 gr load of 2F that bullet will drop between 12" and 13" between 130 and 200 yards.
