My own stash of guides and references:
- Western (powder) -- Reloading Guide v8.0 2020
- SomChem (powder) -- Reloading Guide 2022
- Vihtavuori (powder) -- Reloading Guide 2021
- Alliant (powder) -- website
- Barnes Bullets -- website
- Lee Modern Reloading 2nd Ed -- book/manual
- Hornady Handbook of Cartridge Reloading -- book/manual
- Lyman 50th Anniv. Reloading Handbook -- book/manual
- Sierra Reloading Data 6th Ed -- book/manual
- Hodgdon Reloading -- website
- XXL Reloading -- website (1yr subscription)
- Plus a couple of older guides given to me by experienced reloaders
Caught most of the book/manual examples on sales, or got the prior version at a steep discount.
Haven't found anything missing that I or a couple of buddies needed to search for, for a variety of calibers. Have always found a couple of competing references, to validate a given load. Have occasionally (rarely) found an error or an "outlier" load suggestion, which I then discarded.
Of course, that sort of list is more than most would suggest is needed. But it makes me feel better that I can find several references for anything I'm looking to load. Helps ensure the load's reasonable and validated via the work of others. Being fairly new into this, without the decades' worth of experience many reloaders have, IMO every little bit helps.
