Reading the Ballistic Charts from Office of the Chief of Ordnance -Terminal Ballistic Data III
The Ballistic data from TBD Version III is a little confusing, this page will help you figure them out.
You can find these fascinating books Here for Vol.1, Vol. 2 and Vol. 3, my hat is off to Marcmichael77 over on Scribd., for posting them. Great scan quality and really very interesting. Who knew you could find tables for shrapnel patterns, and blast casualties for pretty much all US weapons on the internet?!
