Went down and dickered around with the 550B, seems to be setup for .223 right now from what I can tell on the toolhead. Guess I need to go rummage through and find some H110 and other components. Seems fitting with what's going on.
Have you loaded your own ammunition before? H110 is primarily a pistol and shotgun powder. It has some rifle applications but not in the 223/5.56 cartridge.
