Never cared much about velocities. IMO: Accuracy is more important. A 240-250 grain saboted bullet fired from the barrel of a muzzeloader rifle using 100 measured grains of Pyrodex gives a velocity of about 1,700 fps. Go to the link and click on Black Diamond rifle for more info.
I read years ago that the "Kentucky Crack" from a Kentucky rifle was made when the round ball went super sonic and that was the load that was sought after. I think it is somewhere around 1100 fps but I could be wrong. My .45 long rifle will do it with a patched .440 round ball in front of 75 grains of ffg goex.

All persons present in uniform should render the military salute. Members of the armed forces and veterans who are present but not in uniform may render the military salute. All other persons present should face the flag and stand at attention with their right hand over the heart, or if applicable, remove their headdress with their right hand and hold it at the left shoulder, the hand being over the heart.
