800X was originally billed as a 12 ga. target powder, which it ain't. It is better suited to large gauge (12 & over) porch and heavy hunting loads, but you shouldn't have to cast far to find better powders (cleaner & more uniform) for whatever you want to do.

Because it is a large flake powder, the metering is especially poor through the small diameter powder bushing needed for the smaller gauges. Again, it's not hard to find better powders.
