Above link is a fun read especially if you slowly view artillery stores and the shipping list, some 360 items (9 Pages of Items). The tie between ammunition types and artillery can be seen here, including the use of sabots (wooden bottoms), cannister rounds in brass cannons but not grapeshot, yet grapeshot for brass howitzers, flannel for developing fixed ammunition, ........ here, a slow read is best.
And see this link, especially: A Different Interpretation of the Battlefield (near the bottom of the page).
