I picked up a nice .50cal TC Hawken. Finally getting a range day, I found out my musket cap wrench won't fit down into the nipple recess in the drum. it's too fat. Trying every make-shift tool I could think of, nothing really worked proper. I finger tightened it, and then snugged it with needle nose pliers and had at it. It was a good day at the range, goals achieved with no problems.
Anybody have this problem? I can't be the only guy with a fat wrench. The only thing I can come up with is to file/grind down the wrench tip, or try to make one out of a small socket.
