Col without the MM book the taxonomy covering all of the MM bullets won't do you much good without the book and photos. An interesting post/thread on the Taxonomy of Trans-Mississippi Theatre bullets, Arkansas, Louisiana, Texas, and Missouri has photos of these unique bullets found to this theatre of the war. The Trans-Mississippi Taxonomy can be found on page 2 of bullets and last entry on Sept 8, 2012. A lot of the leadheads in the forum have more of an interest in this theatre than the others and most of the bullets listed have photos attached.
If you have any question on Trans-Mississippi bullets there are numerous experts on these bullets and I don't classify myself in the same league as some of these guys but post the questions and someone will have the answer.
