Hi Mike,

H777 cleans up beautifully with nothing but cold water. I've used it for years. Run one damp patch, two dry patches, one damp patch, two dry patches, and a patch with T/C 1000+ Bore Butter, and you'll be fine. The second damp patch will probably be clean, so use it to clean the area around the breech. The Bore Butter patch will probably be clean also, so wipe down the barrels on the outside with it.

Despite all the stories to the contrary, I have had absolutely no corrosion, not even the slightest bit, with this cleaning regimen. I don't let my guns sit around after shooting, I clean them right away. As an experiment, I shot my 54 cal Hawken about 20 shots, cleaned it as described above, and put it away for a year. A careful examination revealed a perfect bore. I let it sit another year, and again, perfection.

Make certain there is not a trace of Pyrodex in your bores. Clean them completely, down to bare metal. Then wipe them with T/C 1000+ Bore Butter, and use Bore Butter on your patches. I don't know how important the T/C 1000+ Bore Butter is, because I've never used H777 without it. It might be that it is critical to success, and people have used H777 without T/C 1000+ Bore Butter and had problems; I don't know.

H777 is more difficult to ignite than black powder. In my flintlock rifles I have to use a black powder priming charge. As a result, it is necessary to clean for black powder. Since there is no advantage to H777 in the flintlock, I just use black powder.
