I was reading some back issues of The Museum of the Fur Trade Quarterly. In the Summer 2003 issue, James A. Hanson wrote a piece titled "Percussion Fur Trade Guns". In it he referenced some testing done by the East India Company back in the early 1840s.
He cites two tests of flintlock guns that the EIC conducted. In the first, 13,711 rounds were fired from 1,387 pistols, carbines, and muskets. The total number of misfires were 1,834 or a misfire rate of 13.37%.
In the second test, they fired 19,916 rounds with a misfire rate of 15.67%.
Subsequently, the EIC conducted some smaller scale tests with newly issued percussion arms. "Of 1,080 shots recorded, there were misfires of just 1.57%, a tenth as many with flint guns."
English military arms of the early 1840s using period powder and flints and percussion caps, were 15 times less reliable with flints than with caps.
Another positive the British military noted after the conversion to percussion was that since less gas escaped out the nipple relative to the vent hole, they realized a 13% savings in gunpowder, since they could load the percussion arms with that much less powder and still achieve the same power as they had with flintlocks.
Hanson also commented on the adoption of percussion arms in the western wilderness.
Having hunted arrowheads out here in the West, I can attest to scarcity of suitable stone for making gun flints. Also, the average mountaineer would likely not know how to flint knap, either.
From the Paleo to the Mississippian Period, Indians had to travel long distances or rely on extensive trade routes to obtain stone suitable for making their tools and weapons. And not all of the stone they used for tools and weapons would have made very good gun flints. The idea of picking up any old rock and putting it in the jaws of a cock, and it firing a gun is not realistic.
Hanson's source for the East India Company testing is David Harding, Ammunition and Performance, vol. 3 of Smallarms of the East India Company, 1600-1856 (London: Foresight Books, 1999)

I have often been told that, in the wilderness, one could lose or run out of caps. That is true, but I have not encountered a written account of anyone having done so. Rather, I have read of flint guns being converted to percussion because the powder had been weakened by wetting, thus not being adequate to prime the pan. And, properly-shaped, quality flints are not to be found indiscriminately [emphasis added]. That's why even Indians preferred to purchase European flints rather than make their own.
