500 S&W Mag Cast Load Data Books?

[BigBoreReloader]

I have been trying to find a decent source for cast boolit load data for 500 S&W Magnum loads. It seems that most of the books I've seen top out at 440 grain weights. Can anyone recommend a book or other quality source listing load data for the heavier projectiles (say, 500-700 grain?). Thanks!

Your welcome. Definitely tough to find data for cast loads over that 440 grain mark which happens to be what my Lee mold is.
