If duplex loadings are acceptable for this discussion, the book "The Story of Pope's Barrels" has a number of targets shot by John D. Kelly that are quite impressive.  Most of the targets shown in the book are shot with smokeless, but there are some shot with duplex loads.

Steve Garbe probably knows a lot about this subject I suspect.  He used to hold matches that would give a good idea as to what very good targets would look like.  I had the intention of competing in his "Quart of Blood" matches but by the time I owned a suitable rifle the matches were done.   

Keep in mind that it's also a bit tricky to convert old scores to modern scores because string measure was often used.  Plus reproductions of the targets were often drawings of the groups rather than photos.

Back then quite a few of the bench matches were the old string measure matches. Take a look at the length of string.
