I've loaded a lot of 800X. I think it is great for 1 1/4 Pheasant loads. Used i8t in Springer Field Trials for years. Good velocity and patterns, but easy on the shoulder.
As a lighter load, I would be careful if you are using it in cold weather. I ended up throwing away a case of shells I had loaded from the IMR/duPont loading manual. Bloopers, squibs and so on. It is dirty (I think most slow burning powders are also) but since I clean my guns after each use, that is of no concern to me
