    Shoottng 300blk subs, and 223.
    16 inch, and 10.5 barrels for each.
    Went to check stability calculator on the rounds / twist rares, 220 otm and 55 / 68gr respectively.
    None were low but a couple were over 3.0 .
    No indication on the calculator of what is too much, no upper limit
    Is there a set max to avoid in general?
