Finally shot a few over the chronograph and out of my 22" Henry single shot i get 1240 fps. with a 405 grain boolit over 55 grains of Swiss 2F. Even with that light weight rifle, the recoil is mild. I could up it a fair amount and it would still be comfortable, at least off hand. I begin to understand why people use black in cartridges. And the boom and smoke kind of grows on you too.
