This company publishes reloading manuals for individual cartridges. I bought a .30-'06 manual from them; around 60 pages of loading data. All powders, bullets, and on and on...They also have a .30-30 manual.

The most complete information on exterior ballistics and trajectories, etc, is in the Sierra books. They explain how the calculations are done, and have beaucoup tables and charts.
Best luck,
