As you browse loading manuals as well as find numerous recipes, it's likely that you'll run into calibers that call for magnum primers with some loads yet not with others.

A lot of jacketed bullet loads for this quality ask for magnum guides, yet lead bullet loads make use of normal large rifle guides. The lower line is this. Count on released recipes specifically.
