Rick,
I somehow had a senior moment! The ball is a .570" I don't know what made me think .530"....
Still, it makes no odds in the long run.
The only problem with cornmeal as a filler, is that it can cause extra pressure in a constricted area. That is why we don't use it in the Martini-Henry, as it rams up solid in the neck.
Seeing as this barrel isn't so much constricted at the chamber, but more reduced in bore for the chamber, the cornmeal might do very well though. (the slight constriction there was, I reamed /fine -bored out, to simplify it! )
With this constriction removed, I can now tell that the chamber does not enlarge to bore diameter as I figured previously, so in essence a slight tapering towards the breech if anything.
We have been working on loads for an International musket competition we are just starting, to be run in conjunction with our annual "Victorian Riflemen Shoot" here on the farm on 25th & 26th June.
Most of us have had good luck with a ball using thick wads of felt, and plenty of lube, and no patch..
At 50 metres, they seem like they will group in the black allright off-hand, so that will be something to try.
Re. patches;
I used to wander around thrift /fabric shops with a micrometer in my pocket, seeking out the thickness of good dense linen I needed!! I have a good selection still. :-)
The touch-hole on this barrel is right at the breech face, so any small amount of powder could be used, as long as wadding can be rammed down into the narrower breech area. (or cornmeal)
To all intents & purposes, this barrel is (now) simply a .57" or so bore, then a narrower breech area, with parralell (nearly!) sides.
For cleaning;
a wool mop or brush on the rod would work for both our barrels, as being flexible they should pass through a constriction in your case, or into the narrower chamber in my case, without too much trouble.
Let me know how you get on with your barrel!
Richard.
