I've been archery hunting for last six years but muzzle loader hunted for the ten years previous. I hunted with the traditional hawken rifle, black powder and reg primers. My first five years I was plagued with misfires and missed a lot of animals which obviously sucked. One day I shot at a buck, then reloaded to finish him off & my gun misfired. I removed the nipple & there was no powder visible. Since that day every time I loaded my gun I would remove the nipple & poor a very small amount of FFF into hole. I carried FFF in small flask. For the next five years I never misfired once. Just thought I would pass that on, I have not read about misfires on here, pass on your own advice.
