I don't believe fouling was a concern for stopping rifles as the game was usually shot at very close range and reloading was not an option, especially in a m-loader. A gun bearer would carry an extra rifle to (hopefully) finish the prey if need be! I have shot many m-loading smoothbores, single and SXS, and found that at closer ranges they are very adequate for hunting bigger game. I limit my shots to 50 yards. I have also shot many SXS breechloaders with black powder and a round ball and find that the fouling does not affect accuracy. My Emil Echoldt smooth bore in this post had about 3 dozens black powder rounds fired with out so much as wet patch down the barrels. Oh yes it was DIRTY when I cleaned it but accuracy was not affected!!!....Ed
