As you read packing guidebooks as well as discover different dishes, it's most likely that you'll encounter calibers that require magnum guides with some lots however not with others.
The majority of jacketed bullet loads for this quality require magnum guides, however lead bullet loads utilize normal large rifle guides. The lower line is this. Count on published dishes precisely. You could find non-magnum qualities that require a magnum guide. Or the opposite. Just don't randomly change them by yourself.
