That is neat

Was that a hang fire?

I don't think it's a hang fire. If you compare the relative time in slow motionfor the hammer to completely fall, to the time the spark took to achieve a pretty full bloom (about 1 : 3 ratio) you can figure that if the hammer fell in 1/10 of a second in real time, you had good fire in 3/10 of a second.

What do you rock swingers think?

with my dial up here in the woods.. I will just have to take your word for it.

I give talks to the local schools and take my 2 flinters...I explain what a flint and steel are and then show them how a flinter throws sparks....Now this is with the lock held in my hands, off the rifle...While talking, I proceed to put a little powder in the pan, close the frizzen, bring her to full cock, by this time the kids are backing away from me...
I trip the sear and poof, she lights off, instantaneously....By this time, I have their full attention....That's when you can teach them something about history...

Says it was using ffg powder in the pan. I'd guess ffffg would light off a bit quicker.
