Interesting comment that you bring up about primer "displacing the powder."
I have been meaning to go back and find references to intentionally using weak percussion caps on target guns to get better accuracy....I have never been able to see how this would affect accuracy. On a flintlock, ideally the only thing that goes thru the touch hole is infrared heat wave, so not much of a problem there.
However, I have seen ever so many more articles, including modern writers, that emphasized a strong cap or primer for improving the thouroughness of ignition and improving accuracy. I think the issue there is that burning it all faster results in less variation of muzzle velocity than burning it slower. This would be an advantage of cap over flintlock, but it cannot be a very large issue or we would see the it more with our flinters. I have never seen any evidence of such an issue.
I have seen caplocks "vented" just like a flintlock. this was supposed to help IMPROVE the shot to shot breech pressure and therefore accuracy. It also eliminates the "pressure wave" from the cap firing.
YHS,
