List of Official On-Line Load Data Sources

These are the "official" sources of load data that are available on-line, that I have been able to find. If you know of more, please include them in your post. I will add them to this list so as to serve as a convenient, single-source reference.

Please send me a PM if you know of additional, authorized sources or if a link is incorrect/outdated.

Accurate Arms

Accurate's Lt-32 data

Alexander Arms 50 Beowulf Data

Alliant Please note: Considerable data from Alliant can only be found by going to the "Products" link, selecting the powder in which you are interested and selecting the "View All XYZ Recipes". A great many loads do not show up in the Data Library directly.
