Reloading Load Data: Official Manufacturer Sources
A curated, always-current directory of official, free load data from the powder and bullet makers themselves. We don’t host or alter anyone’s data — we point you straight to the source, so you’re always working from the manufacturer’s own published numbers. Method, not recipes: always work up from current published data for your exact components.
⚠ Read this first — reloading safety
Reloading is inherently dangerous and can cause serious injury or death. The links below point to each manufacturer’s own published data; this directory is provided only as a guideline to help you find official sources. You are solely responsible for your own safety. Always use the manufacturer’s current published data for your exact components, start at the minimum (starting) charge and work up in small increments, and watch for pressure signs at every step. Never exceed a published maximum charge. If you are new to reloading, seek qualified instruction. By using these resources you accept all risk.

Don’t skip the printed manuals
The most thorough, cross-referenced data still lives in the printed handbooks — Lyman, Hornady, Sierra, Speer and Nosler each publish a current edition, and Lyman’s is component-neutral (it spans many bullet and powder brands). If you reload seriously, owning at least one current manual is the single best investment in safe, consistent loads.
Turn published data into your own confirmed load
Published data is a starting point. Your barrel, brass, primer lot and conditions are yours alone — which is why you start low, work up, and confirm the result. These guides cover the method:
Track what you load, dial with what you confirm
Log every session, build a confirmed-load library, and feed real velocities straight into the solver. Free to try — web and Android.
