rigbymauser;
As a point of reference for you, here is my most
accurate load for my WC Scott 10 bore rifle.
RMC turned brass cases, 2 7/8" long.
Winchester 209 primers
215 grains of Swiss 1 1/2 FG black powder
700 grain soft lead round ball.
Two.070" Hard over powder wads and a lubed felt wad to bring
the ball up to the case mouth. Light crimp to hold the ball
in place.
1410 Ft./Sec. (430 M/S) Chronograph measured at 15 ft. (3+ Meters)
This shoots to the sights on my rifle.

That is simply a great looking rifle you have. Very nice!
Any plans to use it on a hunt?
Hope this helps
Raff
