800X, in my opinion, is a miserable powder. There are so many other better choices, regardless of gauge or application. Think about it - there is a reason, in this period of powder shortage, that 800X is still on the shelves. As has been noted above, it is loud (kind of like black powder, it gets the dogs stirred up) and dirty. More importantly, because it is a large flake powder, it meters poorly, especially when using small orifice powder bushings required for small gauges.
