Me too! And as someone else offered ... if at some NMLRA shoot or other range that forbids the practice, I too use a simple 'blow tube' to clear the touch hole.
In regards to any debate about the use of a touch hole pick vs. blowing down the barrel, here's what Larry Pletcher observied in his Touch Hole Ignition Timing tests from the February 2000 issue of MuzzleBlasts magazine:
"While cleaning the barrel between tests, I learned something that may be important in firing flintlocks. Looking through the inspection port opposite the touch hole, I saw that the touch hole was partially clogged. A vent pick was pushed into the touch hole while watching from the inspection port. I could see the dirt being dislodged as the vent pick went through. However, as the pick was withdrawn, the dirt was deposited back in the touch hole where it was at the beginning. This was seen more than once. It made me think that running the pick through the touch hole might not do as much good as I once thought."
