Ash - the paper patched bullets did not reduce fouling, but due to deformation, slugged up to fill varying groove diameters common in those days. A grooved lubricated bullet needs to be closer to groove diameter to shoot well - not so the paper patched bullets with base wads.

My best accuracy from my .45 3 1/4" chambered Hoch barreled Rolling block and my brother's .45 3 1/4" factory M74 Shiloh Sharps gave their best accuracy with bore sized, paper-patched pure lead bullets. We needed to use a lube wad next to the powder (separated by wax paper disks) to make this work. We were able to shoot 10 consecutive shots - no wiping, and push ALL of the fouling out the muzzle with a single dry patch after the 10th shot - just as Paul Mathews explained in his "The Paper Jacket" book. Both of our rifles shot better than 1 1/2 MOA - using their aperture sights only, off bags at 100 meters.

I suggest anyone wanting to try paper patched bullets, to purchase that book by Paul A. Mathews. Another good book on the subject by him, is "Loading the Black Powder Rifle Cartridge.
