TO, Daryl's correct in that your Flint gun should be almost as fast as a cussin gun, to the point the you can't tell the difference. If it's noticeably slower then something's wrong. As I mentioned a powder fuse-powder running from the pan, thru the touch hole and up against the charge. This is sometimes called a hangfire if real slow. You want your charge in the gun, and prime in the pan , but nothing in the touch hole, as the flash is what sets off the charge. Also your touch hole may be too small, I like a 1/16' hole, and even some times enlarge my white lightening's to that size. Touch hole location also effects the speed, a proper one should be near the top of the pan with the top of the hole just at a line that would be drawn across the top of the pan. We know you are hooked, we just want to make sure the hook is set well.
Don't want to lose a fish once we got him hooked.
