1680 is generally far more dirty than H110 in the 300 Blk - in either subs or supers.
H110/296 and Lil'Gun are good choices for subs in a properly set up 300 Blk AR, but if your rifle is a little undergassed then 1680 will help, but at the expense of being louder.

However, 1680 is stupid dirty. I've picked up some H110 and Shooters World Blackout to give them a shot but haven't tried them yet.
The H110 is a faster powder even than 1680 so I'm hoping it will work better in my 6" barrels. I'm also hoping it is less dirty.
