    Generally you won’t be able to use the same powder for the 300-BO, and the 223/556 NATO. The lighter bullet wants a faster powder for optimum performance, while the heavier bullet with about the same case/barrel volume needs a slower burning powder.

    I use Lil Gun for the BO. It was the most accurate of the powders I had on hand. It may not be the “Best” powder. But it does work ok.
