In my Fusil de Chasse, I load 65gr of 2f or 3f, a wad of wasp nest (or tow) about the size of a .62 caliber ball over the powder. Then 65gr of #6 shot topped off with another wad of wasp nest (or tow) same size as the one over the powder. I’ve taken a lot of squirrels with this load and haven’t lost or missed any.
In my .50 caliber Kentucky rifle, I load 50gr of 2f, followed by a wad of wasp nest (or tow) about the size of a .495 round ball. Then I load either a .490 or .495 round ball topped off with another wad of wasp nest (or tow) same size as first. With this load I can put all my shots inside a 4 inch circle at 50 yards shooting offhand. If I use a bench rest and act right, my shots will cloverleaf at 50 yards.
