According Marine Corps Times - Upgrading M16A4

Thanks for the reply. I did not detect a lot of enthusiasm for those powders. Soooo, I will have to buy something else and would very much appreciate your advice on the most likely powder to succeed in my Grendel. It is a Precision 16" Bartlein and I want to shoot it in the Hathcock Match at Cherry Ridge NJ. 20 rounds in 20 minutes prone and single load which allows me to load long if desirable.
Cherry Ridge has swirling wind that is impossible to read - it just blows in circles, so would speed or bullet be the focus. Mark suggested I try Scenar L 120s.
