IMO there is no better or more complete loading data available anywhere than that offered on www.loaddata.com
It costs the price of 1 reloading manual and has the compiled data from 40+ years of Handloader and Rifle magazines as well as nearly all the data from every modern published reloading manual.
An amazing amount of info with a great search function to search by cartridge, bullet weight, powder manufacturer, and powder type. All the data can be printed as well.
If I didn't enjoy reading printed reloading manuals in bed I'd never spring for another copy again.
