Mike,
Abby press has a hugh selection of books and copies of manuals, Ammo catalogues etc. I just ordered an Eley catalogue from the 1880's. The picture I saw of it listed cartridges, bullet weights etc. I haven't received it yet so I can't be sure all of the info I am looking for is there but it should help. I recommend you browse their website you might find something of use for you.
