Well, I have total faith in Ken - a man who really does know what BP is about and has been v. helpful to me and many others over the years. As you can read in the grease thread - ANY kind of NON-petroleum-based grease can be used. I use E45 skin cream, and have done for over thirty years, most shooters over in Germany, where I was intruduced to it in the late 70's, do the same.
BP rifles of the older type - percussion and flintlock, use a lubed patch, but revolvers do not. Single-shot target pistols - LePage, Kuchenreuter and so on, use a lubed patch, too. However, life is just too short to use such a thing in a six-shot pistol - the Indians have been and gone long before you've reloaded......
