Have to say, I’ve never felt a liquid prelubed patch fouled the powder, if shot immediately after loading. I’ve used dawn/water mixture, Hoppes BP lube and spit In various concentrations. Had a discussion with an old timer who figured if the load is tight, except for the exact center diameter of the ball, the lube will be squeezed out atop your ball and spread on the rifling or smooth barrel as you seat you load. Am wondering what caliber, powder charge, ball and patch dimensions are in this trouble firearm and how long it’s setting between completed load and firing. I’ve shot next to people who fill a shallow container with their chosen lube and lay rows of patches in it. The patches are soaked with lube and that’s how they shoot all day.
