    Does anybody use this with good results? I have read a few things online that say its a great clean burn with excellent performance. I am having trouble finding consistent load data for it though. I like to see data in atleast two places and get a estimated start load before I shoot a round.

    Thanks for the information.
    Did you shoot any off a rest for accuracy?

    No I have not tried for grouping yet. My first attempt was to get velocity in the correct range then when I get that in a few different powders i will try them all for accuracy and see how clean they are burning.
