You need a ball puller, which looks like a screw and attaches to your ramrod. It screws into the ball. Then the ball can easily be pulled out. It should work on bullets too, as long as there is some lead to tap into.
Glad you were able to clear it.
Is a terrible feeling on a black powder elk hunt (when I was younger) when you can't get it to fire. Hiked back to the truck and ask dad, "WTF? and he wanted to know how long I had been tromping around with the muzzle down. All it took was doing what you did, and no elk that trip. Lesson learned.
