Quick Answer
Sighting in a 28 Nosler rifle involves a process of fine-tuning the optic and rifle to achieve optimal accuracy. Start with a baseline zero at 100 yards, then adjust for wind deflection and bullet drop at longer ranges. Use a chronograph to ensure consistent muzzle velocities.
Choosing the Right Ammunition and Optic
When sighting in a 28 Nosler rifle, it’s essential to use high-quality ammunition with a consistent muzzle velocity. For long-range shooting, look for loads with a velocity of at least 2,700 feet per second (fps) and a grain weight of 150-170. A high-quality optic with a minimum of 4-14x magnification and a reticle with bullet drop compensation (BDC) markings for the 28 Nosler is also crucial.
Setting Up the Rifle and Firing the Zero Shot
Begin the sighting-in process by setting up the rifle with the optic’s BDC markings aligned with the rifle’s bore. Shoot a group at 100 yards to establish a baseline zero. Use the optic’s BDC markings to adjust the reticle for wind deflection and bullet drop at longer ranges. Aim for a consistent muzzle velocity of 2,750 fps, with a standard deviation of no more than 10 fps.
Fine-Tuning for Long-Range Accuracy
Once the rifle is sighted in at 100 yards, fine-tune the optic and rifle for long-range accuracy by adjusting the reticle’s wind deflection and bullet drop markings. For the 28 Nosler, aim for a 1-mil wind deflection per 100 yards, and adjust the bullet drop markings accordingly. Use a chronograph to ensure consistent muzzle velocities and make adjustments as needed.
