Better bullet for 1000 yards

[Sticks]

I compete with my Grendel, running 123 ELD at 2475 fps. Stays supersonic out to 1200 IIRC where I shoot. The killer is the environmentals. Wind and conditions (temp, pressure) changing through the day makes a massive impact on the Grendel past 600 when you are shooting 1.5 MOA or less plates out to 900y. Just off the edge of a 1 shot per target is still a miss - 2 mph off on my wind call.
