Billy, I shoot / have a few nice flintlocks and yes there is 'tech' to getting a good spark and ignition.

Look up some vids on flint knapping (if you make multiple shots) but I usually get about 20 rounds off before I have to trim a flint (still in the hammer) by chipping the tip.
This pic is proper placement...almost touching the Frizen at 1/2 cock...altho each action has it's own little quirks.
I suggest shooting quite a bit to work up loads/accuracy and get confidence in your ignition....once you get the feel ignition is close to 100%.
Feel free to msg me with anything.....this is all I shoot for fun anymore...I have 2 hand made pre revolution era .54's...just fun.
