lock time
Just a note - another point of view -
Long lock times and frequent failures to fire will test your skill as well as your patience.
I take exception to that as a blanket rule. I rarely shoot caplocks any more, preferring my flint guns. I can count the failures to fire in the last two years on the fingers of one hand - and I shoot frequently.
Long lock times - properly loaded and prepared, there is little to no difference in time between trigger pull and bang when a flint gun is compared to a caplock.
Don't overfill the priming pan - about 1/3rd will do.
Pick the main charge with a vent pick.
Make sure that the priming charge is properly placed in the pan. I usually slap the right side of the gun in order to jog the priming charge over.
Ignition is virtually instantaneous.
