Yes, I do.
The 8 bore had a 30" barrel. Its load was 300 grains of Fg GOEX, an 8 bore lubricated cushion wad, a .015 Wonder Patch and a .820 hand cast ball.
I think that charge chronographed at 1,425 fps.
The 12 bore (72 caliber) was 200 grains Swiss Ffg, 12 bore lubricated cushion wad, .015 Wonder Patch and a .715 ball from Warren Manufacturing (cast and tumbled). The rifle had a 32" barrel.
As I recollect, it chronographed at about 1,800 - 1,850 fps.
Both were exciting rifles to shoot. Sadly, I have sold both of them. Oh well, I do get visiting privileges for the .72 whenever I get up to Washington state. I imagine the same could be said for the 8 bore if I got down to Florida. Children sure do scatter out, don't they?
