Ive got some 4831 we might use if I cant find data. Im open to suggestions.
There are online manuals available with plenty of data. Alliant and Hodgdon both have decent data available. Hodgdon has data for Winchester, Hodgdon, and IMR powders.
Here is a link. www.hodgdon.com
Look in the data center to see if you've got an appropriate powder.
My personal favorites for the short mags are H4350 and Alliant Reloder 17.
edit: Just checked. There are numerous starting and max loads for the 325 WSM in the Hodgdon data center.
