Nah, Joe, the recoil wasn't all that bad, but I will admit to being moved back a step once. I let a fellow shoot it one time and it did spin him around about 180 degrees. Good thing he didn't have cowboy boots on, he might have dug right into the ground. I think it was about a 15 pound rifle, so that helped quite a bit on the felt recoil. IIRC, the ball weighed about 860 grains.
With 300 grains of Fg, the ball left the barrel at about 1,450 fps. With 300 grains of Ffg, it was 1,550 and with 300 grains of Pyrodex Select, it was about 1,625. I asked Chris Hodgdon why Pyrodex did so good, and he replied that I was the expert on big bore guns, no one at his place was about to shoot anything that big. Gee thanks. That didn't quite answer my question.
That was really good fun, shooting those big boomers. Sorry to say, at this point, it is definitely something out of my past, as all my big rifles have gone on to others. Hope they enjoy them as much as I did.
