Point Blank Range Calculator

Maximum point blank range is the furthest distance you can hold dead-on and still land inside the vital zone, with no hold-over. This finds the zero that stretches that window as far as possible for your load.

308 Win — 168 gr match Trajectory through the 8 in vital zone

Light horizontal band is the 8 in vital zone centred on the line of sight. Hold dead centre from 22 yd to 293 yd.

Your zero

Drag the Far zero dot on the chart, use the slider, or type a distance to see how a different zero changes your usable range.

Far zero(yd)

Max height above sight line(in)

Zero this load at 250 yd — or sight in 3.53 in high at 100 yd — and you can hold centre on a 8 in vital zone all the way out to 293 yd. Past that the bullet falls below the bottom edge of the zone and you need hold-over or a dial.
