You can usually get reloading data wherever you buy powder. However, they may not stock the most recent reloading tables. You’re likely to find the most current data on the website for each powder manufacturer, and you can just print it out at index.
*WARNING: Primer Notice: This hull utilizes their "Magnum" primer, which is NOT the same as the Fiocchi 616 primer. Do NOT use the Fiocchi Magnum primer in load data that specifies the standard Fiocchi 616 primer. Always follow the load data and the primer that is called for in the tested load.
