Bioprof: Seems to me that the burden of proof rests in the hands of the critics. Let them prove a ball block was not made in 1757, or earlier for that matter. Men have been boring holes in wood with hot embers, rocks, and metal tips since the stone age. I just can't see much chance that the idea of boring holes in a wood block to hold PRBs waited until the 19th century for someone to think up. I do understand that these kinds of things were done by individuals, that there was really no way to make a profit making them for shooters and hunters, since they could make their own, so we are unlikely to have catalogues, or other written references to such blocks of wood, or to the use of a ball block in the scant writings of the period. Few hunters could read and write, and fewer had the money to acquire, much less have on hand, pencil and paper. So, just who would have been there to write about these things?
