Prior to EACH shot, I "pick-the-flash-channel" with a fairly large, unfolded paper-clip which allows me to reach far into the flash-channel to insure it is clean and fully open, then I wipe off the "nose" of the flint with a clean rag and wipe off the "face" of the frizzen with the clean area of the same rag.
Then I prime the frizzen pan with a fair amount of FFFFg Goex and lean the rifle over slightly to the left and lightly smack the left side of the rifle opposite of the frizzen pan with the "ham" of my hand to insure a little of the FFFFg powder gets into the flash-channel.
Next, I lean the rifle over slightly to the right and "bump" the rifle a bit to insure I level-out the priming powder still left in the frizzen pan and insure the priming powder is not stacked up and covering the flash-hole. Then I close the frizzen, aim the rifle and "FIRE".
By doing these actions consistently, I've found that my flintlock rifle fires just as fast as my percussion cap Hawken rifles... and does so without any noticeable "hesitation" in the firing of the flintlock rifle as compared to a cap-lock rifle.
If there IS any "hesitation", it would be difficult to notice using the techniques I use on my flinter.
I wrote this procedure out fully because I keep reading other's posts who claim the flintlock is "noticeably-slower-to-fire" than a percussion cap rifle. If the procedure I've just outlined (above) is followed, I believe you'll find your "flinter" will fire, without any actual noticeable "hesitation" or a difference in speed, just as fast as a percussion cap rifle normally fires.
It's all a matter of "technique" and using reasonable, workable "methods" to keep all the firing "parts" on a flintlock clean and in good, usable order.
Strength and Honor...
