I like the Lyman & Speer, because they have decent lead bullet data. This is good for extrapolating for coated & plated bullets. Speer is about the closest to reality IMO, I get closer results with their data vs others.
Sometimes the data is VERY different. I'm an old hand, but I've seen some variations so big they bumfuddled me. It's like the old laxative commercial with the prunes. Four enough? Six too many?
