Quick answer

To zero an LPVO at 100 yards, set the scope to its highest magnification, shoot a 3-shot group from a stable rest, then adjust elevation and windage turrets to move the point of impact to your point of aim. Confirm with another group. For a low-power variable optic, this process works whether you have a first or second focal plane reticle, but you must know which you have before trusting holdovers.

Set Up Your Rifle and Scope for a 100-Yard Zero

Before you fire a shot, make sure your LPVO is mounted correctly and your rifle is stable. Use a bipod, sandbags, or a bench rest. Set the scope to its maximum magnification—typically 6× or 8× on LPVOs—so you can see the target clearly and make precise adjustments. If your scope has an illuminated reticle, turn it off or to a low setting to avoid glare. Confirm that your turrets are set to zero and that the reticle is level; a canted scope will throw off windage adjustments.

Fire a Group and Measure the Impact

Aim at the center of a 100-yard target and fire a slow, steady 3-shot group. Do not adjust between shots. After the group, locate the center of the group and measure its distance and direction from your point of aim. For example, if your group is 2 inches low and 1 inch right, you need to move the point of impact up and left. Write these numbers down—guessing leads to chasing your zero.

Adjust Elevation and Windage Turrets

Most LPVO turrets are marked in MOA or MRAD. Check your scope's manual or turret markings to know the click value—often 1/4 MOA or 0.1 MRAD per click. To move impact up, turn the elevation turret in the direction marked 'Up' or 'U'. To move impact left, turn the windage turret toward 'Left' or 'L'. Make the calculated adjustment, then fire another 3-shot group to confirm. Repeat until your group centers on the aim point. Avoid over-adjusting; make changes in small increments and verify.

Confirm and Record Your Zero

Once your group is centered, fire a 5-shot group to confirm consistency. If all shots land within your acceptable group size, your zero is set. Record the turret settings and the ammunition used. If you have a first focal plane reticle, your holdovers will be valid at any magnification; if you have a second focal plane, holdovers are typically calibrated at maximum magnification. Knowing this prevents errors in the field. After zeroing, you can reset your turrets to zero if they have a zero-stop feature.

Step-by-Step LPVO Zeroing at 100 Yards

  1. Prepare your rifle and scope: Mount the LPVO securely, set it to maximum magnification, and establish a stable shooting position. Confirm the reticle is level. A canted scope will cause windage errors—use a level or plumb line to verify.
  2. Fire an initial 3-shot group: Aim at the center of the target and fire three shots without adjusting. Locate the group center and measure its offset from your point of aim. Do not chase a single shot; a group shows the true point of impact.
  3. Calculate and apply turret adjustments: Determine the click value of your turrets and adjust elevation and windage to move the group to the center. Make changes in small increments. If unsure of click value, consult your scope manual—guessing wastes ammunition.
  4. Confirm with a 5-shot group: Fire five shots at the center. If the group is centered and consistent, your zero is set. If not, repeat adjustment and confirmation. A 5-shot group confirms your zero is repeatable, not a fluke.
  5. Record settings and reset turrets: Note the turret positions and ammunition. If your turrets have a zero-reset feature, set them to zero for future reference. Recording your zero settings saves time when re-zeroing or switching ammunition.

LPVO Options for Zeroing at 100 Yards

  • Apollo Zenith 1.2-6×24 LPVO: The Apollo Zenith LPVO offers 1.2-6× magnification, a 30 mm tube, and is designed for quick target acquisition at low power and precision at 6× for medium-range engagements. The 6× top end gives enough magnification for a precise 100-yard zero, while the 1.2× low end keeps the optic fast for close-range use after zeroing.
  • Apollo Phoenix 1-8X24 LPVO: The Apollo Phoenix is a true 1× LPVO with 1-8× magnification, a hybrid horseshoe-center-dot reticle with outer drift-ring, and a rugged 30 mm tube. The 8× maximum magnification provides a tighter sight picture for zeroing at 100 yards, and the bright reticle design helps with aiming point visibility during adjustment.
  • Apollo Terra 1-6×24 LPVO: The Apollo Terra is a 1-6× LPVO with an etched-glass ranging reticle, locking turrets, and a 30 mm tube, designed for hunters and shooters needing fast target acquisition and precision out to 900 meters. Locking turrets prevent accidental adjustment after zeroing, and the ranging reticle can be used for holdovers once your 100-yard zero is confirmed.
