Getting your rifle scope perfectly aligned with your barrel is a fundamental skill. If you’re wondering when sighting in a rifle scope which way to turn the adjustment knobs, you’re in the right place. It’s a common point of confusion for new shooters, but the principle is simple once you understand it. This guide will give you the clear, step-by-step instructions you need to get zeroed with confidence.
When Sighting In A Rifle Scope Which Way To Turn
The golden rule of scope adjustments is this: you always move the point of impact toward your point of aim. In other words, you adjust the crosshairs to follow your bullet holes. If your shots are hitting left of the bullseye, you need to move your crosshairs to the left, which actually means turning the windage knob to the right. This often feels backwards, but it makes sense when you think about it.
Your scope adjustments move the internal reticle. Turning the knob “Right” or “Up” physically shifts the reticle in that direction inside the tube. To make the bullet hit more to the right, you must raise the rear of the barrel by moving the reticle right, pointing the barrel slightly left. Let’s break down the two main adjustments.
Understanding Windage and Elevation Knobs
Every rifle scope has two main turrets, usually protected by caps.
- Windage Knob: This controls left and right movement. It’s typically located on the right side of the scope. The markings often include an “L” and “R” or arrows.
- Elevation Knob: This controls up and down movement. It’s usually on the top of the scope. Markings include “Up” and “Down” or arrows.
Each click of the knob moves the point of impact a specific distance at 100 yards, like 1/4 inch or 1/2 inch. This is called the click value and it’s marked on the knob.
The Simple Rule: “Follow the Shot”
Instead of memorizing a complex chart, just remember this phrase: Follow the Shot. Look at where your bullet holes are on the target. You need to move your crosshairs from the center of the target to that group. To do that, you turn the knobs in the direction you want the bullet holes to move on the next shot.
- Shots are LEFT? You want them to go RIGHT. Turn the windage knob RIGHT (often marked “R”).
- Shots are RIGHT? You want them to go LEFT. Turn the windage knob LEFT (often marked “L”).
- Shots are LOW? You want them to go UP. Turn the elevation knob UP.
- Shots are HIGH? You want them to go DOWN. Turn the elevation knob DOWN.
Step-by-Step Sighting In Process
Follow these steps to safely and effectively zero your rifle.
1. Pre-Range Preparation
- Safety First: Always treat every firearm as if it is loaded. Keep the muzzle pointed in a safe direction.
- Secure Mounting: Ensure your scope rings and base are properly torqued to the manufacturers specifications.
- Bore Sighting: Use a bore sighting tool or the old-fashioned method to get your first shot on paper. This saves time and ammo.
2. The Initial Shots
- Set up a large target at 25 yards. This makes it easy to get on paper.
- Fire a careful 3-shot group from a solid rest, like sandbags or a bipod.
- Go downrange and mark the center of that group with a pen or sticker.
3. Making the Adjustments
- Do not move the rifle. Look through the scope and place the crosshairs back on the bullseye.
- Have a friend tell you how far off your marked group is, or use a target with a grid.
- Calculate the clicks. If your group is 8 inches left at 25 yards, and your scope clicks are 1/4″ at 100 yards, that’s 32 clicks left needed. But remember, at 25 yards, each click is 1/16″. So 8 inches divided by (1/16) = 128 clicks. This is why the 25-yard method is for rough alignment.
- Turn the knobs according to the “Follow the Shot” rule. Remove the turret caps and adjust.
4. Final Zero at Distance
- Move your target to your desired zero range, like 100 yards.
- Fire another 3-shot group. It should be much closer to center.
- Measure the distance from the bullseye and make your final, precise adjustments using the click values for 100 yards.
- Fire a final group to confirm. When you’re satisfied, replace your turret caps without disturbing the settings.
Common Mistakes to Avoid
- Chasing a Single Shot: Always adjust based on a group of shots (3-5 rounds). A single flyer is not a reliable indicator.
- Poor Shooting Position: You must eliminate human error. Use a solid rest and focus on consistent trigger pull and cheek weld.
- Forgetting Parallax: If your scope has a side focus or adjustable objective, set it for the correct distance to avoid parallax error, which can cause aiming inconsistency.
- Loose Hardware: Double-check that all screws on the rings, base, and rifle action are tight before you start.
Tools That Make the Job Easier
Having the right gear can streamline the process significantly. A shooting rest or sandbags are essential for stability. A spotting scope or binoculars lets you see your hits without walking downrange every time. A small notebook is great for recording your adjustments and final zero settings. Don’t forget a screwdriver set or Allen wrenches that fit your scope mounts.
FAQ: Your Sighting-In Questions Answered
What does “MOA” mean on my scope turret?
MOA stands for Minute of Angle. It’s a unit of measurement. 1 MOA is roughly 1 inch at 100 yards. So, a scope with 1/4 MOA clicks moves the impact 1/4 inch at 100 yards per click. At 200 yards, that same click moves it 1/2 inch.
Why are my shots still scattered after adjusting?
If your groups are large and inconsistent, the problem likely isn’t the zero. It could be your shooting fundamentals, the rifle’s bedding, inconsistent ammunition, or even a scope that’s failing to hold zero. Focus on shooting a tight group first, then move it to center.
How often should I re-check my zero?
It’s a good habit to check your zero before any important hunting trip or competition. Also check it if you drop your rifle or bang the scope hard. Changes in temperature and humidity can sometimes effect it, but usually a quality scope will hold zero for a long time.
My turrets don’t have clear markings. How do I know which way to turn?
Most scopes turn clockwise to move impact up and right. But the best way is to test it. At close range, fire a shot. Then, turn the elevation knob 20 clicks “up.” Fire another shot. If the second shot is higher, you know “up” means up. If it’s lower, then “up” on the knob means down on the target. Write it down for future reference!
Sighting in your rifle is a satisfying and essential task. By remembering to “Follow the Shot” when deciding which way to turn the knobs, you remove the mental gymnastics. Take your time, be methodical, and always prioritize safety. With a good zero, you can head into the field or onto the range with full confidence in your equipment’s performance.
