My L.H. full stock flint, Chambers large Siler lock, 3/8 - 32 White Lighting touch hole ,chunk rifle it has a 1 1/2 x 44 .45 Douglas barrel . It likes 90 grains Swiss FFF .451 ball and Wayne Lambson's teflon patching .I us a drop tube clean after each shot and try to seat the ball with the same amount of pressure each time. If I do my part it will stack them right on top of each other.
