    Hodgdon Book

    155g 8.5 max
    180g 6.9 max

    Hornady Book

    155g 8.8max
    180g 7.6max

    Both with a 4 inch barrel, 1 in 16 twist, both Hornady case trimmed .845", and both with Winchester Small Pistol primers. I was amazed that they were all the same.

    Am I safe with the Hornady data in an XDm with 4.5" barrel?

    Yup, brand and specific powder is crucial to know since each one has different properties and thus, different starting/max. load data.

    Sorry about that... Hodgdon HS-6 is the powder. I copied this all from a post elsewhere, must have missed the powder text. Bit by the copy/paste monster.

    I would likely start with the data from the powder manufacturer, and start making a dozen or so with a weight halfway between their listed minimum and maximum, to be safe. (If the maximum load only is given, then I would start 10% less than max.) I'd shoot those and if there's no problems, then I may decide to go to within 5% to 10% of the max. I tend not to make hot loads, but that's my personal preference.

    Yes loads change over the years due to new powder formulas and IMO legal issues my data book is about 15 years old.
