AA2520 was one of Bill Alexander's (creator of the Grendel) favorite powders for the Grendel. Burn rate was just right for a wide variety of Grendel projectiles relative to the case size.
I believe the formula has been changed slightly in recent years and NEW 2520 is close, but not exactly the same, as ORIGINAL 2520.
Anyway, I'd recommend using AA2520. Western Powders has quite a few loads using it in their Handloading Guide on page 56.
