This question is for JerryJ, I have a .260 Rem. in 15" Encore and sight in dead on @ 200yds. Puts me less than 3" high @ 100yds, with 120gr Nosler BT @ 2500+ FPS. I have not shot @ 300yds, but believe that from the ballistics program on Realguns.com, it would be 9" low @ 300, still on your 12X12 plates.
Would it be easier to sight in dead on @ 200yds? I had no problem with deer last fall with this combination.
I am looking forward to spring and woodchuck hunting with this gun.
Just an observation.. Rol
