    Question for Bryan on load data for 300 Norma please.
    We discussed this caliber at 2015 Nationals and I am finally about to send rounds down the tube on one!
    After some data on loads if possible for 215H and 230H with Retumbo and also just got some RE26 delivered?
    I have run the throat out .130" over the standard full neck bearing surface engagement on my reamer. Now approx half the neck engages on the bearing surface of a 230 GR hybrid.
    Norma case with .001 neck tension. Fed 215 primers.
