OK, OK, I'll yield!
Although I have seen somewhere the bit about soldiers being executed is largely myth.
Brown Bess was so named because the metal was browned.
While sub-caliber rounds were used for more shots due to fouling, the average soldier equipped with a Brown Bess was lucky to get off two rounds before employing his bayonette, that being the standard miiltary strategy of the day.
I have heard of soldiers proficient enough to reload a musket while prone, these being the legendary Algerian French origiinal "Zouave" units, but that was a bit later.
Black powder guns lobbed large chunks of lead because, like air guns, their velocity was low. The advent of high pressure smokeless powder ushered in the lighter, high speed bullet.
And, once those multi-shot Austrian guns ran out of air, it took something like several thousand pumps to refill them. Supposedly spare reservoirs were hooked to pumping mechanisms attached to wagon wheels so they could be recharged while on the move. (PCP owners - Do Not try this with your scuba tanks and pickups!)
