I think Herr DFD posted a very interesting question. I can only comment about here in New England. I tend to think round ball was used for some large game hunting, that is deer, but buck-and-ball loads were likely very common too. For most hunting, the various sizes of shot likely prevailed for fowling along the large river valleys like the Connecticut River, Thames River, Niantic River and so on. By 1750 there weren’t that many deer left in southern New England anyway. I think musket balls were also widely used in warfare as it was typically mandated that each militiaman (virtually everyone between 16-60)had a working firelock and so many rounds of ammunition or so many lbs of “bullets.” Take the memoirs of Joseph Plumb Martin, a Connecticut soldier (born MA), who was a young private during the American Revolution. He related one incident in New York where he witnessed a soldier take his “piece” with a six foot long barrel, which he rested on a fence, and pick off a British soldier “certainly over half a mile” away. Whether true or not, it does suggest some serious shooting with round ball. Martin also noted a soldier who had his musket charged with buckshot, which the British called “Yankee peas.” In another interesting incident he mentions melting down musket balls to make shot to hunt squirrels and pigeons. Had he been caught he would have been severely reprimanded. Now whether New Englanders cloth patched the ball, that I don’t know, but I think ball, shot, and buck and ball, were used in many combinations with a lot of different kinds of wadding.
