I tried AA 1680 in .223 and it was not good, not good at all. Which is a shame since I think I have a full pound of it at the bottom of the powder magazine.Accurate 1680
Best luck I have had is with H-335, with RL7 right behind. Currently using CFE 223 and H4895, because nowadays I load with whatever I can get my mitts on...
Edit to add, if you have good data for that powder, I might try it again.
