Have you gotten any help yet, Fatelvis? I'm thinking of trying to do the same thing. I use Quickload a lot, but have never added a powder file. I've heard that 4759 wasn't added because it was "going to be discontinued". I don't think that is so any more. I think it caused too much of a ruckus from the cast bullet crowd, and rightfully so. I'll be following this thread, and will add any progress(?) that I make.
