Thanks for all the advice cayugad. Very helpful, I appreciate it. I was swabbing with T/C black powder solvent every 3 or 4 shots, so that may have been the reason for the hangfires. Like I said, I haven't shot a sidelock much at all for quite a few years so I've got to get back into the routine. I will try the 3F Triple 7, and maybe a musket cap nipple if I can find one. Our early muzzleloader deer season starts September 25th, so we COULD have dry weather, but it's hard to say. Being western Washington, it could rain every single day just as easily. September is normally one of our dryer months of the year, but weather this summer has been different, to say the least.
