Fred,I think every gun is different and you have to find out what works best in your firearm. I have found in my ROA that a reduced load with a cream of wheat filler gives the most accuracy. I like using lubed wads or grease cookies to keep the fouling soft. It may not be historically accurate, but the older I get, the more I want things that make it easier.
I’m in your camp. I forgot grits the last two club shoots and I notice hard fowling build up. Swiss 3F. I also incorporate grease cookies. ROA. I get a lil better accuracy and the fouling is completely removed after 10 shots with one dry patch. 18 grains of Swiss 3f, milk carton wad, small scoop of grits, pea size of lube, .457 ball topped. Reminds me. I gotta pistol to clean today!
