You need a ball puller to pull the ball, then the patch if that didn't come, and the powder should come out with some hits from the ramrod to loosen it. Once your rifle is clean I'd be sure to take it out of the stock and remove the nipple and make sure everything gets clear and dried.

I use bore butter on my traditional...but before I shoot it I only use dry patches to swab. Maybe the wet patches did something with the bore butter that stuck in the barrel? You also should have used more than one dry patch just for good measure, and then a few caps to clear the firing channel. That should make everything go well. And next time you see some pick up some #11 mag caps and a hot shot nipple. They're a great combination to stop those hangfires I hope everything works out with your bobcat, tell me how that el-cheapo shoots!
