Well, Jimmy Veeeeeeeeeeeeeeeeeee, here is my reasoning for using a .010 patch in the ol' T/C. How deep is the rifling in a T/C 1:48 barrel. Maybe .006" on a windy November day with the rain coming down? Always seemed a thin patch worked better with shallow rifling, and a thick patch with deep grooves.
Seems to me that when I was selling Ox Yoke products, they had .005, .010, .015 and .020 in plain cotton patches and .017 and .022(?) in ticking. They came in various lube choices as well, dry, oiled, Wonder Lube and at one time, silicon. Then we had product from a fellow in Colorado and he had several other thicknesses to choose from in diameters for each caliber: .45, .50, .54 etc. Our patching area took up two full set of inventory shelving. Good grief, it were something.
