I've had the same experience as asmntman. The only mis-fires I've had with a caplock have been when target shooting and swabbing every shot. After 6-10 shots I end up pushing fouling down into the channel and have to remove the nipple and add some powder to get her to go. I don't pop a cap before loading on a clean barrel, just don't see the need when I clean with the plunger method.
