How to Zero a Rifle Scope

Get on paper fast and dial in a solid 50- or 100-yard zero.

1. 1
   Mount level and torque

   Level the scope, set proper eye relief, and torque the rings to spec. A loose or canted scope will never hold zero.

2. 2
   Bore sight to get on paper

   Pull the bolt and look through the bore at the target, then adjust the scope to roughly match — or use a bore sighter. This saves ammo.

3. 3
   Fire a 3-shot group

   From a stable rest at your zero distance, fire three careful shots. Aim at the same point each time — you're reading the group, not a single shot.

4. 4
   Adjust to the group center

   Measure from the group center to the bullseye and dial the turrets (remember MOA vs MIL and clicks per inch at your distance).

5. 5
   Confirm

   Fire another group to confirm. Repeat until centered, then note your zero and load.
