How to Sight In a Barnett Crossbow

Start close so your first shots land on the target, not in the dirt behind it. Set a target at 10 yards, put the top aiming point - your 20-yard crosshair - on the center, and shoot. At this range the bolt prints high, which is fine; you are only confirming the scope is roughly aligned and nothing is loose.

Once you are hitting near center at 10 yards, move the target back to 20 and treat that as your true zero distance. Shoot from a solid rest rather than offhand, so you are reading the bow and scope instead of your own wobble.

Twenty yards on the top crosshair is the number everything else hangs off. Fire a group of three, see where it lands, and move the point of impact with the turrets.

On a Barnett 4x32 the windage and elevation turrets move the point of aim about one tenth of an inch per click at 20 yards, so roughly ten clicks shifts impact an inch. Dial toward where you want the group to go: hitting low means adjusting up, hitting left means adjusting right. Use the same bolts and point weight you intend to hunt with, because a heavier or lighter arrow changes where this zero sits. Keep shooting three-shot groups and adjusting until the group centers on the bull.

The stacked lines below your zero are holdover marks for longer range, and the labelled distance is only a starting guess. Barnett's manual lists each line across a span rather than a single yard figure, because the real distance depends on your bow's speed and arrow weight:

Shoot each line at a measured distance and note where it actually lands, then record the real yardage for each. For the full breakdown of what the lines mean and why they drift, see the scope and yardage-lines page. Tape your real numbers to the stock - that is the step that makes the reticle trustworthy in the field.

Sighting in is not a one-time job if your setup changes. Swapping between 20-inch and 22-inch shafts, moving between Headhunter and a third-party bolt, or adding a lighted nock all change arrow weight, and weight changes both speed and point of impact. Any of those means re-checking the 20-yard zero before you trust the lines again.

If you are not sure which bolt your bow is built around, confirm it on the fit by model page first. A Hyper-series bow on narrow Hyperflite shafts sights in the same way but will not group at all on the wrong bolt family.

Two mechanical things undo good sighting-in. The first is shooting without a rest while you zero, which blends your wobble into the group and sends you chasing adjustments you do not need. The second is loose scope rings. Crossbow recoil is a short, sharp impulse that works ring screws loose, so torque them evenly in stages and re-check after the first twenty shots.

A bow that will not hold zero is almost always a scope moving in its mounts rather than a bow fault, so check the rings and rail screws before you start turning turrets again. If something structural feels off, the parts page covers what is worth inspecting.
