Check your spread/grouping at 500 or 600 yards. If it’s 3-5 inch then you can forget the ES out of your chrony, and go hunting. I’ve been running RL25 in my 6506ai and getting 2930 fps with RP brass, ES <10. And 2980 fps with Norma brass but ES is up around 30-40. I settled on the RP and slightly slower speed
