I spent most of December and January shooting pistols, single shot percussion and flintlock and revolvers, all were 44s and 45s. I shot a total of 6 different pistols.
Only 3F was used and the loads ranged from 18 to 30 grains depending on the pistol and only round balls were used. All shooting was done for paper matches, not hunting, accuracy only.
After a bit I had to shift my shooting range (cows on the range) and started shooting into my wood pile with the target frame in front of the pile.
When shooting the single shot percussion and flintlocks, I did not hear from my wife. When I started shooting the revolvers she came out and said that is enough, the balls are hitting the house. Not believing her I went back to shooting. When I heard a ball hit my truck, I quit.
When I started looking at the end of the firewood, I noticed that where I had shot the percussion and flintlock single shots, the balls were embedded in the wood. Where I had shot the revolvers, there were many balls barely stuck in the wood or where a lot just bounced off the wood.
The difference in the pistols I see, is that there is a loss of energy in revolvers when the ball jumps from the cylinder to the barrel which does not happen in single shot pistols.
In all honesty, I do not think black powder pistols have a place in hunting for critters much larger than small game, they do not have the energy that is needed to do the necessary work in quick order.
And most people are not what I consider to be adequate pistol shots to put the ball where it needs to go.
Just my opinion,
