I have some Hornaday 150 Gr. Round Nose bullets on the way and I want to load them in my .30-30 cases. I would like to know about load data. I have load data using 150 grain Speer Flat Point bullets and I have the powders for that bullet but I cannot find any load data using the Hornaday 150 Gr. Round Nose bullet. Can I use the same data (as far as powders are concerned) as the Speer Flat Point bullet but swap the Hornaday 150 gr. round nose bullet in the .30-30 cases? Thanks all, 74man
