Agreed! I don't think flinters pay enough attention to the touch hole. You can have the best, most efficient lock on the market, but if your touch hole isn't totally clear of crud when you pull the trigger, you will experience a mis- fire, a hang fire, or a flash-in-the-pan.
With a 12" piece of rawhide, attach a brass wire touch hole pick of "slightly" smaller diameter to one end, and the other end attached with a loop to the front of your trigger guard. USE THIS PICK WITH EVERY SHOT!!!
I use FFFg with all my flintlocks, .36 cal. to .58 cal., because I'm cheap! I use FFFFg to prime all these weapons because it works effectively! If I had to spend the extra effort to drop some FFFFg under my charge of FFFg, I'd probably go back to centerfires!
A well tuned flintlock, a sharp flint of quality, a degreased flint edge and frizzen with an alcohol patch, a meager priming powder charge, and a totally cleared touch hole to the main powder charge, provides an instantaneous, flinchless explosion.
This is the beauty of flintlocks. If the shooter adheres to each step needed by the rifle to provide immediate response, there is seldom or never a malfunction.
With flintlocks, one must remember, the action is on the outside of the rifle, the powder charge and patched round ball are inside the barrel. The channel between the two must be absolutely clear of crud! The lock, flint, and frizzen must be clear of burnt powder, and oilyness, and the priming powder must be dry and away from the touch hole.
Only the shooter can control all these factors before pulling the trigger, and if a malfunction occurs, the shooter must look no further than him/herself as the cause.
Enjoy the up-coming season, but be totally prepared before pulling the trigger.
