cayugad,

Good shooting on those squirrels and nice gun. I've got an old Traditions Springfield Hawken that I've had for about 25 yearsor so with a 1-66 twist. It's a real nail driver with those round balls. Mine has the fixed sights and I really had to do some filing on that front blade to get it shooting good when I first bought it. I have also killed a couple of squirrels with mine and a couple of foxes. I've never tried Pyrodex in mine. I've always used Goex 2f (90 to 100 gr). By-the-way, I kept mine loaded in the gun cabinet (in the house) for several months after deer season last year. When I finally took it out to shoot it, it shot on the first try like it had just been loaded.I know that's not a great idea but mine worked fine. Anyway, you got a great looking old gun there.
