I am cayugad, but no muzzleloading genius. Reference your question, my pet load for my CVA Staghorn Magnum is 90 grains of Goex and a 245 grain Powerbelt. With this combination accuracy is exceptional. I have the rifle topped with a Bushnell Trophy RED DOT because scopes are forbidden in Wisconsin during muzzleloading season. Yet the rifle with that load and RED DOT will keep a 4" group or betterat 100 yards all day long. I think I could shoot further then that but just to get that kind of distance in this country, I have to shoot all the way across my front yard, between two buildings, and then across the back yard to the target out into the woods. Most shots are around 60 yards and under here with 35-45 yards being much more common.

I personally would not worry about that load out to 125 yards and further. With the load your talking,if you can place your shot, you better know how to butcher. You could take deer a long distance with it.
