I have been using a lot of Accurate 11FS the last couple of years. It is basically W296/H110 with a flash suppressant added. This came about by requests from the 300 Blackout crowd. The added suppressant makes the powder just a "tick" slower than W296/H110 and slightly boosts velocity in most reported loads. If you can't find load data for it, data for W296H110 can be used.
The best thing about the powder is it's several dollars a pound cheaper than W296/H110.

I know there are some very good "new" powders out there
