I've never used those bullets before, what kind of bullet is it, jacketed, plated, lead, other?
Which data you use, is going to depend on what type of load your wanting to develop. For instance, I load jacketed bullets, and I like Longshot, HS6, Blue Dot, and other slower burner's, cause I like full throttle loads. As far as data, as long as it comes from a published source, Hornady, Speer, Sierra, Nosler, Hodgdon, Lyman for example, it's considered as reliable published sources.
