Flintlock touch holes Special type?

Does anyone remember if there were touch holes made for Thompson Center and other flintlocks that had a special design to make them more efficient? I seem to remember they existed, and I believe mine went down the drain during one of my more recent cleaning sessions. I replaced it with one I had and for the first time in a long while I had the pan go off without igniting the powder in the chamber. Am I dreaming or did those touchholes really exist? Thanks, Kurt
