My zero for EFT is 35 yards. This is a .22 MRD @985 fps. I use the same technique using my ballistic app in calculating EFT as I do AAFTA FT zero. This gives me the flattest trajectory possible with the smallest amount of clicks or holdover.
^ Ditto. I think my true 'zero' is around 30-32 yards but it's basically flat from 25-35 and the ballistics app likes using 'far zero'. Everything is hold over.
