Find an old wool felt hat, [try Goodwill or the Hospital auxilliary],buy or make a 3/8" wad cutter and punch out many wads. Soak half of them in lube[ Wonderlube, beeswax and olive oil or Crisco have all worked for me]load 20 grains of 3f, a dry wad then a greased one, then ram in your ball.Play with the powder charge, up and down, 2 grains at a time, and make a note of the result. Ideally, the charge should bring the ball to just barely under the mouth of the chamber, whether the powder has been reduced and partially replaced by cornmeal or not.This load will shoot clean and accurately all day in my Navy. Have fun!
