Well I finally took my first step into reloading. I bought and read "The Complete Reloading Manual for the 45-70 Government". I was disappointed to find that the speer 300 grain was not in this "complete manual". So I am wondering what reloading manual would give me the most information for this bullet loaded with H322 and RL7 powders. Or maybe a better question would be, what is the best reloading manual for the 45-70?
