I watched a couple guys at the range increasing powder charge with each shot, shooting thru a chrono. I think they used Pyrodex, and were shooting .50 cal with buffalo type bullets maybe 300 grain. Any how, velocity increased a little with each shot, from 60 grains up to about 90, then stayed at 1800 fps all the way thru 120 grains. They concluded 80 grains was good enough. Then they got out a Win 1886 in 45-70 and said it kicked too much and would I like to buy it for 300 dollars. I still kick myself for not grabbing it.
