Default rifling methods / cleaning antique gun bores

Ward,
Thanks for posting the pics of the rifling process used in pre-industrial America. One would suspect that similar methods were used in the Ottoman Empire (the majority of Turkish "shishhane" guns are rifled) since both the Turks and the rifle-makers of colonial Pennsylvania looked to the same ancestral source for the rifle concept: the German-speaking world.

As far as taking the pains to check and clear the barrels of old guns, you are spot-on. I have a couple of other tips, given me by veteran shooters of black-powder guns, which I've used for years and that you might find useful.

1. Besides removing any old charges, an important part of cleaning is removal of any layers of powder fouling from previous shots. Most modern shooters mistakenly use some of the commercial petro-based solvents such as Hoppes No. 9, but although these work fine to remove lead deposits and the fouling from nitro powders and mercuric primers, it doesn't do much for the "glaze" of old black powder combusion residue which is itself a moisture trap. BOILING HOT WATER WITH LYE SOAP is a tried-and-true old time black powder solvent. Dismount the barrel from the gun (or else be very careful not to wet the stock), and use an old metal teakettle to pour the hot stuff down the muzzle to flush thoroughly, then work on it with your brush-on-rod tool until the water spritzing from the touch-hole is clean.

2. Stubborn scales of rust clinging to the bore can be attacked with penetrating oil (Break Free is a good product). Plug the touch hole, fill the bore with the stuff, stand the gun in a corner and forget about it for several days, then work on it with your bore tools. Repeat as necessary. In the pre-Break-Free era, one guy told me that he had good luck with Coca Cola (the old classick formula). He learned that after reading a report about how the stuff could free up seized engine cylinders and dissolve things like typewriter keys and the galvanizing off of nails that were soaked long enough in it. ( BTW just think of what this infernal bevridge can do to your stomach lining under such circumstances. I got religion after hearing about this and immediately gave up Coke in favor of beer )

After cleaning, make sure bore is dry and you can oil with your favorite lubricant; a guy on another forum uses Ballistol and I can vouch for the durable protection it provides.
