I own lyman 49th ed. and it is fantastic. still, that there are numerous resources online regarding others' experiences with various loads using the exact same bullet--just google for yourself! surprisingly, these online recommendations can vary significantly from lyman's published load data, and in at least one instance, lyman's listed min and max loads were SIGNIFICANTLY hotter than the majority of the recipes i found online (how many grains of bullseye for a .452" 200gr lswc???).
my point is that the internet is a great resource, as are, i am sure, the resources that other, more experienced users mentioned above. read it all and take everything with a grain of salt!
