I have found that most HDY load data has maxes that are higher than Accurate maxes. I haven't found the 10mm data at all wimpy (at least for the powders I run). 800-X with a 180 is probably a load that needs to be revised down - especially considering where Underwood loads to. That one is smoking hot!
