Introduction
A precision rifle is only as effective as the glass sitting on top of it, and even the most expensive optic is useless if it is not correctly aligned with the bore. For the tactical enthusiast or the serious prepper, the .22 LR (Long Rifle) is more than just a plinking tool; it is a vital asset for low-cost training, small game hunting in a survival scenario, and discrete pest control. We have spent years in the field and on the range, and we know that a sloppy zero leads to missed opportunities and wasted ammunition.
At Crate Club, we emphasize that mastering the fundamentals of your gear is the first step toward proficiency. If you are building out your kit at the same time, you can choose your Crate Club tier and align your gear with the same mindset you bring to the range. This article provides a technical, step-by-step breakdown of how to zero a .22 rifle scope, covering everything from initial mounting and bore sighting to calculating adjustments at the range. Whether you are prepping for a survival situation or sharpening your marksmanship, a reliable zero is non-negotiable.
Quick Answer: To zero a .22 rifle scope, start by bore sighting the rifle at 25 yards to get on paper. Fire a three-round group, calculate the necessary clicks based on your scope's MOA or MRAD adjustments, and move the point of impact to your point of aim. Finally, confirm your zero at your preferred distance, typically 50 yards for a .22 LR.
The Importance of the .22 LR Zero
The .22 LR is a unique caliber because of its relatively low velocity and high trajectory arc. Unlike a 5.56 or .308, which have flatter trajectories at common engagement distances, the .22 LR "rainbows" significantly. This makes the distance at which you zero your scope critical. If your zero is off by even a fraction of an inch at 25 yards, that error will expand exponentially as the distance increases.
For a prepper or tactical shooter, the .22 is the ultimate "trainer." It allows you to practice the same fundamentals of trigger squeeze, breathing, and follow-through as a full-sized centerfire rifle but at a fraction of the cost. If your zero is not perfect, you are training yourself to compensate for a mechanical error rather than refining your skill.
Step 1: Pre-Range Gear Inspection
Before you ever chamber a round, you must ensure your hardware is properly installed. A scope that is loose in the rings will never hold a zero, and you will waste a box of ammunition trying to chase a moving target. If you want to stock up on essentials before range day, you can also browse the Gear Shop for practical range-ready equipment.
Checking the Mounts and Rings
Ensure your scope rings are torqued to the manufacturer’s specifications. Most tactical rings require between 15 and 25 inch-pounds of torque. Over-tightening can crush the scope tube or interfere with the internal adjustment turrets. Use a drop of blue thread locker on the base screws to prevent them from backing out under the vibration of repeated fire.
Setting Eye Relief and Leveling
Eye Relief is the distance between your eye and the rear lens of the scope where you see a full, clear image without black shadows around the edges. Adjust the scope forward or backward in the rings until your eye relief is comfortable in your natural shooting position.
Next, ensure the reticle (the crosshair pattern) is perfectly level. If the scope is "canted" (tilted to the left or right), your windage and elevation adjustments will interfere with each other. If you adjust for height, the bullet will also move horizontally. Use a small bubble level on the rifle's receiver and another on the scope's elevation cap to ensure they are aligned.
Addressing Parallax
Parallax occurs when the reticle and the target are on different focal planes, causing the crosshairs to seem to move if you move your head. Many .22-specific scopes have a fixed parallax at 50 yards, while higher-end tactical scopes have a side-dial adjustment. Ensure your parallax is set for the distance you are shooting to avoid aiming errors.
Step 2: Selecting Consistency in Ammunition
You cannot zero a rifle using three different brands of ammunition. The .22 LR is notoriously sensitive to variations in bullet weight and muzzle velocity. A 40-grain subsonic round will have a completely different point of impact (the place where the bullet actually hits) than a 32-grain high-velocity round.
For a reliable zero, select the ammunition you plan to use most often. If you are building a survival kit, choose a high-quality round like CCI Mini-Mags or a match-grade subsonic load and stick with it.
Field Note: When zeroing, buy several boxes of the same "lot number" if possible. Even small variations between different manufacturing runs of the same brand can shift your zero enough to miss a small target at 75 yards.
Step 3: Range Setup and Stability
To zero a rifle, you must remove as much human error as possible. You are testing the mechanical alignment of the optic and the barrel, not your ability to shoot off-hand. If you want a broader refresher on the process, how to zero a rifle scope is a useful companion read.
- Use a Solid Rest: Use a dedicated rifle sled, sandbags, or a sturdy bipod with a rear squeeze bag.
- Pick the Right Distance: While 100 yards is the standard for many centerfire rifles, 50 yards is the "gold standard" for a .22 LR. It provides a balance between a usable point-blank range and the trajectory of the bullet.
- Target Selection: Use a target with a clear grid. Targets printed with 1-inch or 1/2-inch squares make calculating your adjustments much easier.
Step 4: Bore Sighting
Bore sighting is the process of aligning the center of the barrel with the center of the scope. This does not give you a final zero, but it ensures your first shot will at least hit the paper. For a deeper walkthrough, what a bore sight is used for explains the basic process in more detail.
The Bolt-Action Method
If you are using a bolt-action rifle, remove the bolt and look through the barrel from the rear. Center the target in the middle of the bore. Without moving the rifle, look through the scope. Adjust the windage (horizontal) and elevation (vertical) turrets until the reticle is centered on the same target.
The Semi-Auto Method
For semi-autos like the Ruger 10/22, you cannot look through the bore. You can use a laser bore sighter or simply start your zeroing process at a very close distance, such as 10 or 15 yards. If you are on target at 10 yards, you will likely be on the paper at 25.
Step 5: The Initial Grouping
Once bore-sighted, move your target to 25 yards. This is a "shortcut" distance that makes the initial adjustment easier. If you want to understand the tool side of that step, how bore sighting works is a solid follow-up.
Step 1: Fire three rounds. Do not aim at where the first bullet hit. Always aim at the exact center of the bullseye for every shot in the group.
Step 2: Find the center of the group. Disregard any "fliers" (shots that went wide due to a bad trigger pull).
Step 3: Measure the distance. Use a ruler or the grid on the target to measure how many inches the group is from the center, both vertically and horizontally.
Step 6: Calculating Adjustments (MOA and Mils)
This is where most shooters get frustrated. To adjust correctly, you need to understand the math of your turrets. Most scopes use MOA (Minute of Angle), while some tactical scopes use MRAD (Milliradians).
Understanding MOA
1 MOA is approximately 1 inch at 100 yards. Most scopes have "1/4 MOA" clicks. This means 4 clicks move the point of impact 1 inch at 100 yards.
However, because you are zeroing at 25 or 50 yards, the "value" of those clicks changes:
- At 100 yards: 4 clicks = 1 inch
- At 50 yards: 8 clicks = 1 inch
- At 25 yards: 16 clicks = 1 inch
Making the Adjustment
If your group is 2 inches low and 1 inch to the right at 25 yards:
- Elevation: You need to move the impact UP. If your scope is 1/4 MOA, and you are at 25 yards, you need 16 clicks per inch. (2 inches x 16 clicks = 32 clicks UP).
- Windage: You need to move the impact LEFT. (1 inch x 16 clicks = 16 clicks LEFT).
Key Takeaway: Always move the turrets in the direction you want the bullet hole to go. If the bullet hit low, turn the elevation turret toward "Up." If the bullet hit left, turn the windage turret toward "Right."
Step 7: Refining the 50-Yard Zero
Once you are hitting the bullseye at 25 yards, move the target out to 50 yards. This is where you will perform your final "precision" zero. If you want a more detailed look at practical bore-sighting accuracy before live fire, how accurate bore sights are covers what to expect from the tool itself.
- Fire a five-round group. A five-round group provides a better statistical average than a three-round group.
- Calculate the adjustment. At 50 yards, each 1/4 MOA click represents 1/8th of an inch. If you are 1/2 inch high, you need 4 clicks DOWN.
- Confirm. Fire another three to five rounds to confirm the point of impact matches the point of aim.
Our Captain tier often features the types of range tools and EDC (Everyday Carry) gear that make this process easier, ensuring you have the maintenance equipment needed for field adjustments. If you want to compare what comes in that tier, see the Captain crate.
Step 8: Creating a DOPE Card
Once you have a 50-yard zero, your work isn't done. You need to know where that bullet will land at 75 yards, 100 yards, and beyond. This data is called DOPE (Data on Previous Engagement).
The .22 LR drops significantly. A typical high-velocity round zeroed at 50 yards might drop 6 inches at 100 yards. Spend time shooting at various distances and record how many clicks or which "holdover" point on your reticle is required to hit the center. Tape this small chart to your rifle stock or keep it in your range bag. If you are putting together a kit for this kind of field note-taking and maintenance, start with the Lieutenant tier and build from there.
Field Note: Environmental factors like temperature and altitude affect the .22 LR more than most calibers. Cold air is denser and will cause the bullet to impact lower. If you zeroed in the summer, check your zero again when the first frost hits.
Common Mistakes to Avoid
Even experienced operators can run into issues when zeroing a rimfire rifle. Keep an eye out for these common pitfalls:
- Chasing the Shot: Never adjust your scope based on a single shot. Always shoot a group. A single shot could be a fluke or a mechanical inconsistency in the ammunition.
- Ignoring the Barrel Heat: While a .22 doesn't get as hot as a .300 Win Mag, rapid fire can still cause the barrel to expand and shift the point of impact. Take your time between groups.
- Dirty Chamber: Rimfire ammunition is notoriously dirty (carbon and lead buildup). A fouled barrel or chamber can degrade accuracy. Clean your rifle every 200–500 rounds to maintain zero consistency.
- Improper Eye Position: If you do not have a consistent "cheek weld" (the way your face rests on the stock), your eye will be at a different angle each time, leading to parallax errors.
Tactical Applications for the .22 LR
In a tactical or survival context, the .22 LR is an essential tool. It allows for "stealth" small-game hunting that doesn't alert everyone within two miles to your location. It is also an excellent tool for introducing new shooters to the fundamentals of marksmanship without the intimidation of recoil and muzzle blast. If you want to keep building your knowledge after dialing in your scope, how to use a bore sight is a natural next step.
A well-zeroed .22 can also serve as a formidable defensive tool in extreme circumstances, provided the operator can place shots with surgical precision. This precision is only possible with a scope that has been zeroed with care and verified through practice.
Bottom line: Zeroing is a marriage between your barrel, your ammunition, and your optic; if you change any of those three variables, you must re-zero.
The Crate Club Standard
We believe that high-quality gear is the foundation of readiness, but the skill to use that gear is what makes an operator. Whether you are using a Lieutenant-level EDC kit or the professional-grade tactical equipment found in our Major tier, the principle remains the same: verify your equipment.
Crate Club was founded by Spec Ops veterans who know that in the field, there is no "undo" button. Your gear must work the first time. By taking the time to properly zero your .22 rifle scope, you are ensuring that when you squeeze the trigger, the result is exactly what you intended. If you are ready to keep improving your setup, get a crate delivered monthly and keep your kit moving forward.
Summary Checklist
- Ensure scope rings are torqued and the reticle is level.
- Select one specific ammunition type for the zeroing process.
- Start at 25 yards to get "on paper" and save ammunition.
- Understand the click values for your specific distance (e.g., 16 clicks per inch at 25 yards).
- Finalize and confirm the zero at 50 yards.
- Record holdover data for longer distances on a DOPE card.
FAQ
What is the best distance to zero a .22 rifle?
For most general purposes, 50 yards is the ideal zero distance for a .22 LR. This provides a relatively flat trajectory from 20 to 60 yards, which covers the majority of small game hunting and tactical training scenarios. If you only plan to shoot at very close range or indoors, a 25-yard zero is acceptable, but you will need to account for significant bullet drop beyond 50 yards.
How many clicks move the bullet one inch at 50 yards?
On a standard scope with 1/4 MOA adjustments, it takes 8 clicks to move the point of impact one inch at 50 yards. This is because 1 MOA is roughly one inch at 100 yards (4 clicks), so at half that distance, the clicks are worth half as much. Always check your scope's turrets to confirm if they are 1/4 MOA, 1/2 MOA, or MRAD-based.
Why does my .22 rifle lose its zero?
The most common reasons for a lost zero are loose mounting hardware, significant changes in ammunition, or extreme temperature shifts. Rimfire rifles also experience significant lead and carbon buildup, which can affect the barrel's harmonics and accuracy over time. Ensure your rings are torqued correctly and use a drop of blue thread locker to keep screws from vibrating loose.
Can I zero a .22 scope without firing a shot?
You can "bore sight" a rifle without firing, which aligns the optic with the barrel, but you cannot achieve a true zero without live fire. Bore sighting only gets you close enough to hit a large target at short range. Factors like the ammunition's velocity and the barrel's unique vibrations mean you must always confirm and refine your zero with actual rounds on a range.
