When I bought my first muzzle loader as a teenager in the '70's I used muslin from Mother's quilt material stash, usually the outside edges of bed sheets where they were not worn. I cut round patches to size, melted Crisco on the stove, dropped the patches in and fished them out with tweezers. They would dry in a nice tight stack that I could easily peel patches off of in the field. That first rifle had a very smooth rifled bore, and it worked very well with this combination. Later as I bought more rifles, some of the bores were rougher, so I went up to pillow ticking, laundered and treated the same way. Check your recovered patches they should show rifling steaks and a dark spot in center where the ball was. My mountain rifle burned patches something awful and I had to go with a progressively smaller ball and thicker linen patching before it began to wear in and shoot better. Each barrel is its own separate entity it seems.
