Load data isn't interchangeable but I've had similar good results with all the 4350s. I stick with the H version now as it's one of the Extreme powders, but they all work well. AA4350 is easily the slowest of the three. Never found any of them to be dirty. I use a CCI-200 unless I'm loading a magnum case then I go with Fed.215M or CCI-250.
