I've heard that flintlock guns have slightly higher pressures than percussion guns. Is that true?

No. They actually have less because touch-hole vents some of the gas.

Anyway, have a friend fire just a small pan of FFFFg in a unloaded flintlock, take notice of the shape of the "poof" cloud it makes...
Now do the same with the muzzleloader loaded, have a friend shoot it while you watch (from behind)...
Besides the "poof" cloud of the priming powder, there will also be a jet stream of hot smoke shooting out at a right angle to the barrel via the touch hole...
Depending on the size of the gun's vent and the size of it's main charge loaded, this could range from a few inches to several feet in length...
This is why some military muskets were fitted with flash guards, to protect the shooter on your right from the hot gasses, the flash guard will direct the jet stream of gas upwards...

When shooting a flint lock, one must keep in mind what is beside the lock, I once set a bale of hay on fire while out hunting groundhogs in the summer, the hot gas from the main charge was enough to ignite the dry hay with ease...

if you video tape your range work and replay it at a slower playback....you will see that when the main charge goes off and the ball starts to leave the barrel....the flash hole will suck the smoke back in the flash hole....pretty neat to see...........................bob
