Sighting in a rifle at shorter and longer ranges, such as 25 and 100 yards respectively, allows for a trajectory that intersects the point of aim at both distances. This process compensates for the parabolic arc of a projectile’s flight path. For instance, a rifle zeroed this way might impact slightly high at 50 yards, on target at 25 and 100 yards, and slightly low at 150 yards. This provides a practical aiming solution for engaging targets within a typical hunting or competitive shooting range.
This dual-range zeroing method offers versatility and ethical shot placement in diverse scenarios. It leverages an understanding of ballistic trajectories to maximize accuracy within a defined range. Historically, hunters and marksmen have employed similar techniques to improve accuracy without complex calculations, relying on practical experience and field testing. Modern ballistic calculators refine the process but the underlying principles remain the same.
