Solved from this product's advertised 2950 fps, 140gr bullet and G1 BC 0.496, with the sight 1.5" over the bore at standard conditions. Compare every zero for .270 Winchester, or read What Is the Best .270 Winchester Zero for Elk?.
How to read it: filled circles are the near and far zero, where the bullet's path crosses the line of sight;the triangle is the peak (max ordinate). The shaded band is the 8" vital zone, ±4" either side of the line of sight. The dashed line marks the edge of the hold-dead-on window. The chart is zoomed to where the zero matters; the tables below run to 500 yards.
