The .22 Long Rifle is inherently accurate, capable of shooting well under 1 inch at 50 yards depending heavily on the rifle and ammunition quality. In precision bolt-action platforms paired with match-grade standard velocity ammunition, shooters can realistically expect 0.25 to 0.50-inch 5-shot groups at 50 yards. Standard factory hunting rifles and semi-automatics generally produce 1.5 to 2.0-inch groups with bulk high-velocity ammunition. Accuracy is most heavily influenced by ammunition consistency, wind conditions, and avoiding the transonic barrier by using subsonic match loads. While high-velocity rounds offer flat trajectories for hunting, subsonic ammunition remains the definitive choice for precision target shooting.

Understanding .22 LR Accuracy
Accuracy is standardly measured in Minute of Angle (MOA). One MOA translates to approximately 1.047 inches at 100 yards, which means it translates to roughly 0.5 inches at 50 yards. If a .22 LR rifle shoots 1 MOA, its bullets should form a half-inch circle at 50 yards and a 1-inch circle at 100 yards in perfect environmental conditions.
When evaluating precision, the number of shots fired per group changes the results drastically. A 3-shot group demonstrates a rifle’s mechanical potential when the barrel is cold, but it lacks statistical proof of consistency. A 5-shot group introduces barrel heat and slight shooter fatigue, providing a much more realistic measurement of field performance. A 10-shot group exposes the maximum dispersion limit of the rifle and the inevitable inconsistencies found in rimfire ammunition. Because .22 LR ammunition is mass-produced and relies on a rimfire priming compound, random flyers are common. Shooters testing accuracy should rely on 5-shot averages or larger 10-shot aggregates to truly understand their rifle’s capability.
Manufacturer accuracy claims typically rely on cherry-picked 3-shot groups from indoor test tunnels. Independent testers fire 5-shot or 10-shot groups outdoors. This explains why a manufacturer might claim quarter-inch capabilities, while a reviewer testing the same rifle outdoors records a 0.75-inch average.
Typical .22 LR Accuracy
The .22 LR is chambered in a wider variety of firearms than any other cartridge, and expectations vary wildly depending on the platform. 50 yards is the universal testing standard for this caliber.
- Precision Bolt-Action Rifles: Custom-built rimfires (like the Vudoo V-22 or RimX) and high-end factory rifles (like the CZ 457 MTR or Tikka T1x) represent the gold standard. When fed premium match ammunition, these rifles consistently produce 0.25 to 0.50-inch 5-shot groups at 50 yards.
- Factory Hunting Bolt-Actions: Standard hunting bolt-actions generally deliver 0.75 to 1.50-inch groups at 50 yards with decent factory ammunition. This is more than precise enough for ethical shots on small game.
- Factory Semi-Automatic Rifles:Standard factory semi-autos like the Ruger 10/22 typically produce 1.5 to 2.0-inch groups out of the box with bulk ammunition. However, adding a custom heavy barrel and a match trigger can quickly shrink semi-auto groups down to 0.50 inches.
Best .22 LR Ammo For Accuracy
Ammunition quality is the single biggest deciding factor in .22 LR accuracy. Because rimfire cartridges cannot be handloaded by the consumer, shooters must test different factory loads to find what their specific barrel prefers.
| Ammunition | Bullet Weight | Type | Supersonic / Subsonic | Reported Group Size | Distance | Best Feature | Source |
| Eley Tenex | 40 grain | Flat Nose | Subsonic | 0.25 inch avg (5-shot) | 50 yards | Olympic-level consistency | General Data |
| Lapua Center-X | 40 grain | Lead Round Nose | Subsonic | 0.35 inch avg (5-shot) | 50 yards | Exceptional reliability | General Data |
| SK Rifle Match | 40 grain | Lead Round Nose | Subsonic | 0.45 inch avg (5-shot) | 50 yards | Affordable match precision | General Data |
| CCI Standard Velocity | 40 grain | Lead Round Nose | Subsonic | 0.75 inch avg (5-shot) | 50 yards | Best value practice load | General Data |
| CCI Mini-Mag | 36 grain | Plated Hollow Point | Supersonic | 1.00 inch avg (5-shot) | 50 yards | Reliable hunting expansion | RifleShooter Magazine |
No single load will be universally the most accurate in every rifle. Eley Tenex and Lapua Center-X are widely considered the absolute benchmark for precision, frequently dominating benchrest competitions.For hunters, CCI Mini-Mags provide an excellent balance of acceptable accuracy and terminal performance.
Supersonic vs Subsonic .22 LR Accuracy
Unlike centerfire rifle cartridges where faster is almost always better for accuracy, the .22 LR operates under unique physics regarding the speed of sound.
- Subsonic Accuracy (Standard Velocity): Standard velocity ammunition travels around 1,050 to 1,080 feet per second. Because it never breaks the sound barrier, it avoids the transonic shockwave. This provides the absolute best mechanical accuracy, which is why every Olympic-grade match load is subsonic.
- Supersonic Accuracy (High Velocity): High-velocity loads travel at 1,200 to 1,400 feet per second. While they shoot flatter initially, they slow down rapidly due to poor aerodynamics. As the bullet drops below the speed of sound (usually between 50 and 75 yards), it enters the transonic zone. The disrupted air currents cause the bullet to yaw and tumble slightly, which instantly opens up group sizes. High-velocity ammo is excellent for hunting inside 50 yards, but it is a poor choice for precision target shooting at 100 yards.
Barrel Length And .22 LR Accuracy
The .22 LR uses a very small powder charge that achieves a complete burn within the first 14 to 16 inches of the barrel.
- 16 to 18 Inches: Highly maneuverable and an excellent choice for a hunting rifle or suppressor host. The short barrel is incredibly stiff, which reduces harmonic whip and frequently produces world-class mechanical precision.
- 20 to 24 Inches: These lengths are popular on target rifles. They do not increase velocity. In fact, friction inside a 24-inch barrel can actually slow the bullet down slightly compared to a 16-inch barrel. The primary benefit of a long barrel is a longer sight radius for iron sights and adding forward weight to help steady the rifle on a benchrest.
Twist Rate And .22 LR Accuracy
Twist rate, the distance it takes for the rifling to complete one full rotation, is highly standardized for this caliber.
The industry standard and nearly universal twist rate for the .22 LR is a 1:16 twist.
This twist rate perfectly stabilizes the traditional 36-grain to 40-grain bullets at standard velocities. Unless a shooter is utilizing highly specialized 60-grain subsonic sniper ammunition (which requires a fast 1:9 twist to stabilize the heavy projectile), a 1:16 twist is required for maximum accuracy.
Bullet Weight And .22 LR Accuracy
The .22 LR operates in a very narrow window of bullet weights.
- 32 to 36 grain (High Velocity): These lightweight options are designed for maximum speed and flat trajectories inside 50 yards. They are highly susceptible to wind drift and are generally utilized for pest control rather than target shooting.
- 40 grain (Standard and Match): The ideal weight for the cartridge. It offers the best balance of gyroscopic stability and momentum. Every premium match-grade load on the market utilizes a 40-grain lead bullet because it consistently produces the tightest groups.
- 45 to 60 grain (Heavy Subsonic): Designed for maximum energy retention at very slow speeds. While extremely quiet when suppressed, they generally offer poor accuracy in standard 1:16 twist barrels because they lack the necessary spin to remain stable.
Effective Accuracy Range
The .22 LR is highly affected by gravity and wind, making long-range precision a challenge.
- 50 Yards: The optimal zero distance. Quality rifles will easily print 0.5-inch groups, and bullet drop is minimal.
- 100 Yards: The high ballistic arc becomes apparent. A standard velocity bullet drops roughly 6 to 8 inches from a 50-yard zero. Mechanical accuracy can still hold around 1 MOA (1 inch), but wind reading becomes critical.
- 200 Yards: The bullet drops roughly 35 to 40 inches. At this range, a 10 mph crosswind can push the bullet a massive 15 inches off target. Precision is possible, but it requires specialized optic bases with built-in elevation to dial the scope enough to compensate for the extreme drop.
- 300 Yards: The extreme outer limit for organized rimfire competitions. Hits on steel plates are possible, but environmental variables make tight groupings practically impossible.
Factors That Affect .22 LR Accuracy
Several unique variables influence the cartridge’s precision:
- Ammunition Lot Testing: Even premium ammunition varies slightly from batch to batch. Competitive shooters will buy a dozen different lot numbers of the same brand, test them all, and then buy a massive quantity of the specific lot that their barrel preferred.
- Chamber Dimensions: A match-grade chamber is cut tighter and shorter than a standard sporter chamber. The tighter tolerances force the bullet directly into the rifling upon chambering, significantly improving accuracy.
- Wind Drift: The blunt, slow-moving .22 LR bullet has a terrible ballistic coefficient. A gentle 5 mph breeze will push the bullet off target easily, making wind reading the most important skill for rimfire accuracy past 50 yards.
- Rimfire Ignition: The priming compound is spun into the rim of the cartridge casing. If the compound is unevenly distributed, the powder burn will be inconsistent, resulting in vertical flyers on the target. Premium ammunition uses strict quality control to minimize this flaw.
.22 LR Accuracy With A Suppressor
The .22 LR is arguably the best cartridge in the world to suppress, particularly when firing subsonic ammunition.
A high-quality rimfire suppressor will rarely degrade the rifle’s mechanical accuracy. In fact, the added weight on the muzzle often dampens barrel harmonics and strips away turbulent gases, which can shrink group sizes. However, threading a suppressor onto the barrel will cause a Point-of-Impact (POI) shift. The bullets will remain highly accurate, but they will strike a different location on the target, requiring the shooter to re-zero their optic.
Manufacturer Data vs Independent Testing
When researching .22 LR accuracy, shooters must distinguish between laboratory claims and field realities.
Manufacturers frequently advertise accuracy based on groups fired indoors from heavy test fixtures. This removes wind, recoil, and human error entirely. High-end ammunition manufacturers like Eley and Lapua even operate indoor testing facilities specifically for shooters to match ammunition to their rifles.
Independent reviewers test the cartridge using consumer-grade rifles shot from a bipod outdoors. Because of real-world variables, especially wind drift, a rifle and ammunition combination that claims 0.25 MOA in a lab might routinely print 0.75-inch averages in independent outdoor field testing.
Best .22 LR Setup For Accuracy
For the shooter looking to extract the maximum practical accuracy from the .22 LR, the ideal configuration is:
- Rifle: A premium bolt-action utilizing a rigid chassis or laminate stock with a match-grade chamber (such as a CZ 457 MTR or a custom Vudoo V-22).
- Barrel: A 16- to 20-inch free-floated, heavy-contour (bull) barrel featuring the standard 1:16 twist rate.
- Optic: A high-magnification, first-focal-plane precision optic featuring an adjustable parallax down to 25 yards to ensure a crisp target image at close rimfire distances.
- Ammunition: Eley Tenex or Lapua Center-X standard velocity ammunition for extreme target precision, or SK Rifle Match for high-level practice.

Loads utilizing 40-grain standard velocity (subsonic) projectiles, specifically Eley Tenex and Lapua Center-X, consistently provide the tightest groups.
Is .22 LR accurate at 100 yards?
Yes. With subsonic match ammunition and a quality rifle, shooters can expect 1-inch groups at 100 yards, provided they accurately correct for wind drift.
Is .22 LR accurate at 200 yards?
Mechanically, yes, but practically, it struggles. The extreme bullet drop and vulnerability to wind make hitting small targets at 200 yards a significant challenge.
Are subsonic .22 LR rounds accurate?
Yes. Subsonic .22 LR rounds are actually the most accurate option available. Avoiding the transonic barrier ensures the bullet remains stable all the way to the target.
Are supersonic .22 LR rounds more accurate?
No. Supersonic (high velocity) .22 LR rounds are less accurate at distance because they destabilize as they drop below the speed of sound.
Does barrel length affect .22 LR accuracy?
No, a shorter barrel does not inherently ruin mechanical accuracy. A stiff 16-inch heavy barrel can be just as mechanically precise as a 24-inch barrel.
Does twist rate affect .22 LR accuracy?
Yes. A 1:16 twist is strictly required to stabilize standard 36- to 40-grain bullets.
Does a suppressor affect .22 LR accuracy?
A suppressor does not degrade group sizes, and frequently improves them by taming barrel harmonics, but it will shift the point of impact on the target.
What bullet weight is most accurate in .22 LR?
The 40-grain bullet is universally considered the most accurate for target shooting, as it offers the best balance of stability and momentum.
