Thread: Accuracy or ES?

Hi all,
Just shot some groups with 162 eld-x in the 7mmRSAUM
Used Norma and Remington brass.
Got very good groups with norma brass but larger ES.
Remington brass ES of between 5 and 3 fps but groups not that great. Norma ES 20-25fps but tight group.
So what's more important and why. I've gone group but at up to 1200 yards on steel will the larger ES make that much difference?
