With muzzle loaders you can only burn a certain amount of powder from ignition until the projectile leaves the barrel. Old timers would shoot over snow and tune back until they had no un burnt grains of power on the White stuff this gave them maximum loads.Powder burns at different rates FFFFG is very fine and used for frizzens or ignition powder FFFG for smaller cals, FFG for larger, FG for cannons. I use FFG for my 45 and bigger cals FFFG for my 38 cal. Pressures increase with finer powders cause they burn faster, producing pressure faster. Grade of powder I think is more dangerous than amount of the correct grade for the calibre, I wouldn't use FFFG in my 500 BPE I stick to FFG, I would need to research it well before changing to the finer powder, obviously FPS increase is the result
