I apologize, I just got off the phone with my friend and he pulled up the data, and we got that ES with IMR 4831. It was 74 Deg. the day we shot it, and when he went out this fall to sight in for Rifle Season, his results were more sporadic (as to be expected according to him) it was 88 degree's and his ES is now around 45 according to his data, so maybe it was just one of those days.
