I am quite aware of the limits of the Continental, and European loading techniques. I thought the original poster was seeking improved accuracy, while still using paper patched balls.
I think people shooting these smoothies have to make a decision, as to they are going to try to be period correct, and historically correct in what they do with the Brown Bess, or are they going to attempt to actually get some accuracy from it.
If they want to re-enact, they are probably firing blanks, only.
If they really want accuracy, then a PRB on top of a OP wad, or filler, on top of the powder charge in the barrel, serves as a fire wall, and will be the correct choice of loading. Then do something with the bayonet lug to make a true sight out of it, and decide on how you are going to make something to reference as your rear sight. That will give you accuracy UNHEARD Of back in the days when these were the Battle Arms of the infantry. The wads or filler, will also act as a gas seal- far better than a cloth patch around the ball with these light charges of powder. Both tend to scrub the bore as they exit- although corn meal fillers are the best at this-- helping to keep it clean.
If you lube the bore with a good wax/oil based lube before the first shot, the lube will feed the cloth patch, and provide a slick surface that will NOT hold powder residue well. I have found this to be the case using my Young Country 101 lube, now sold as "Bore Butter", or " Wonderlube", when used that way in my 20 gauge fowler.
My lube does NOT foul the powder, when its loaded. And, if you are shooting at a target range, there is NO restriction on you using a Powder drop tube, to load the powder down at the bottom of the barrel without touching the sides of the bore on the way down. A drop tube will also position fillers on top of the powder without touching the bore on the way down, too. :hmm:
If you use an OP wad, make sure its at least .010" Larger in diameter than the actual bore diameter of you gun. Track of the Wolf sells fiber wads that meet these requirements. But, You HAVE TO MEASURE THE BORE OF YOU GUN, and not rely on what the factory stamps on the side of the barrel to determine its actual diameter in thousandths of an inch! :shocked2: :thumbsup:
