This will not be for specific loads, although some may be listed, but will be broken down for supersonic powders, subsonic powders, powders that work for both, as well subsonic powders for bolt action and single shot, and may be broken down more as things progress. It is a beginning and the list will be adjusted and or modified as things progress. So this is going to be a List of powders that can be used in the 300 blk. Often powders that are way to slow to be used effectively in the 300 blk. They are constantly asking about powders.
