Everybodies right. The breechplug are not tightened, so it makes the touchhole position look worse than it is. But, the touch hole is too low. The fix is an oversized touch hole liner. For some reason almost all the early importers did this. I put a 5/16” liner in one of those sea service smoothbore pistols, and it worked like a champ. You just have to drill a pilot hole where you want the touch hole to be, and then drill it out with the proper number drill for the tap, easy pleasey.
