The main difference between .22 WRF and .22 LR is the diameter and length of the cartridge case, which makes them completely incompatible with each other. The .22 WRF features a thicker, longer case and typically fires a heavier 45-grain flat-nosed bullet, delivering slightly more kinetic energy than standard rimfire loads. In contrast, the .22 LR uses a narrower, shorter case and is the most widely produced cartridge in the world, offering unmatched affordability and firearm selection. While the .22 WRF was highly regarded for small game hunting in the early 20th century, it is largely obsolete today. The .22 LR remains the modern standard for plinking, training, and hunting, whereas the .22 WRF is strictly a specialty round kept alive to feed antique firearms.

The Main Difference Between .22 WRF And .22 LR
When comparing .22 WRF vs .22 LR, the most defining difference is the physical dimension of the brass case. The .22 WRF (Winchester Rimfire) was introduced in 1890 as a more powerful alternative to the standard .22 caliber rimfire cartridges of the era. It utilizes a case that is noticeably longer and wider than the .22 LR. Because the case is larger, it safely holds more powder and pushes a heavier 45-grain flat-nosed bullet.
Historically, this gave the .22 WRF a distinct power advantage, making it a favorite for small game hunters who wanted a harder-hitting projectile. Today, modern high-velocity .22 LR ammunition can match or exceed the velocity and energy of the .22 WRF. The .22 LR benefits from over a century of continuous development, resulting in vast improvements in bullet aerodynamics and propellant efficiency. The .22 WRF is now an obsolete specialty cartridge manufactured in small, seasonal batches, while the .22 LR is the undisputed global standard for rimfire shooting.
.22 WRF vs .22 LR Dimensions
Cartridge dimensions dictate powder capacity, chamber compatibility, and barrel bore requirements. The .22 WRF case actually served as the parent case for the modern .22 Winchester Magnum Rimfire (.22 WMR), which explains its wider profile.
Based on specifications published by the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), the .22 WRF measures:
- Bullet diameter: 0.226 inches
- Case length: 0.965 inches
- Rim diameter: 0.300 inches
- Case diameter: 0.245 inches
- Overall cartridge length: 1.180 inches
The .22 LR measures:
- Bullet diameter: 0.223 to 0.2255 inches
- Case length: 0.613 inches
- Rim diameter: 0.278 inches
- Case diameter: 0.226 inches
- Overall cartridge length: 1.000 inches
The .22 WRF case is significantly longer and noticeably wider (0.245 inches compared to 0.226 inches) than the .22 LR case. The .22 WRF also utilizes an internally lubricated bullet, whereas traditional .22 LR bullets feature external wax lubrication.
.22 WRF vs .22 LR Velocity
Velocity controls both trajectory and kinetic energy. The .22 WRF was originally a black powder cartridge, but modern manufacturers load it with smokeless powder to achieve consistent speeds safely.
Comparing representative factory loads tested from standard rifle barrels yields the following figures:
- CCI .22 WRF (45-grain jacketed hollow point): 1,300 fps.
- Winchester .22 WRF (45-grain lead flat nose): 1,300 fps.
- CCI Standard Velocity .22 LR (40-grain lead round nose): 1,070 fps.
- Federal AutoMatch .22 LR (40-grain lead round nose): 1,200 fps.
- CCI Stinger .22 LR (32-grain copper-plated hollow point): 1,640 fps.
A standard factory .22 WRF load operates at 1,300 fps, which is faster than standard-velocity .22 LR ammunition. However, the .22 LR is available in specialized hyper-velocity loads that easily surpass the speeds of the older .22 WRF.
.22 WRF vs .22 LR Energy
Muzzle energy measures the striking force of the bullet. Energy is derived from a formula combining bullet weight and velocity. Because the .22 WRF uses a heavier 45-grain bullet moving at a solid velocity, it produces excellent kinetic energy for a rimfire cartridge.
Representative muzzle energy figures based on manufacturer specifications include:
- CCI .22 WRF (45-grain): 169 ft-lbs.
- Winchester .22 WRF (45-grain): 169 ft-lbs.
- CCI Standard Velocity .22 LR (40-grain): 102 ft-lbs.
- Federal AutoMatch .22 LR (40-grain): 128 ft-lbs.
A factory .22 WRF load hits with roughly 169 foot-pounds of energy, making it noticeably more powerful than a standard 1,200 fps .22 LR load. This extra energy, combined with the traditional flat-nosed bullet profile, made the .22 WRF highly effective for anchoring small game cleanly.
.22 WRF vs .22 LR Range
When evaluating .22 WRF vs .22 LR range, shooters must clearly differentiate practical effective range from maximum projectile travel. Maximum projectile travel denotes the absolute distance the bullet can fly if launched at an optimal upward angle. Both of these projectiles can travel over a mile under ideal circumstances, requiring a safe backstop for every shot.
Effective range specifies the maximum distance at which a bullet retains sufficient accuracy, velocity, and energy to ethically dispatch game. The .22 WRF has an effective hunting range of approximately 50 to 75 yards. Its flat-nosed bullet is not aerodynamically efficient, causing it to shed velocity rapidly over distance.
The .22 LR retains functional velocity and striking energy much further downrange because modern manufacturers offer highly aerodynamic, copper-plated projectiles. A shooter can zero a .22 LR rifle at 50 yards and effectively strike small targets out to 100 yards with predictable holdovers.
.22 WRF vs .22 LR Accuracy
Accuracy relies heavily on the quality of the firearm and the consistency of the ammunition. Today, the .22 LR is vastly more accurate than the .22 WRF, entirely because of modern manufacturing priorities.
In documented independent testing, the .22 LR frequently produces incredibly tight groups at 50 yards simply due to the existence of highly specialized, match-grade rimfire ammunition. Brands like Eley and Lapua manufacture extreme-precision .22 LR loads designed specifically for benchrest and Olympic competitions.
The .22 WRF is no longer produced with match-grade accuracy in mind. Ammunition manufacturers produce .22 WRF in very limited, basic batches intended strictly for keeping antique hunting rifles operational. Furthermore, most rifles chambered in .22 WRF are over 80 years old, and their barrels often show significant wear that degrades accuracy.
.22 WRF vs .22 LR Recoil
Both of these cartridges are celebrated for their exceptionally light recoil, and the practical difference between them is virtually zero. Cartridge energy and the overall weight of the firearm dictate the perceived recoil impulse.
When discharged from a standard 6-pound rifle, a .22 LR produces approximately 0.2 foot-pounds of free recoil energy. A .22 WRF fired from a similar antique rifle generates roughly 0.3 foot-pounds of recoil energy.
Both cartridges generate a tiny fraction of a foot-pound of recoil force, making the physical sensation completely imperceptible to the shooter. Both are entirely comfortable for shooters of all ages and sizes to fire all day without any shoulder fatigue.
.22 WRF vs .22 LR Ammunition Cost
Ammunition cost heavily favors the .22 LR, which remains the most affordable factory ammunition available worldwide. Current retail prices dictate how often a shooter can practice without financial strain.
As of September 2026, representative retail prices for common factory loads indicate:
- Federal AutoMatch .22 LR (40-grain, 325-round bulk box): $19.50 to $26.00 per box, equating to $0.06 to $0.08 per round.
- CCI Standard Velocity .22 LR (40-grain, 50-round box): $4.50 to $6.00 per box, equating to $0.09 to $0.12 per round.
- CCI .22 WRF (45-grain JHP, 50-round box): $20.00 to $30.00 per box, equating to $0.40 to $0.60 per round.
Practicing with a .22 WRF typically costs five to ten times as much per trigger pull as practicing with standard .22 LR ammunition. The .22 WRF is a seasonal, niche cartridge, meaning it does not benefit from the massive economies of scale that keep .22 LR prices incredibly low. Furthermore, .22 WRF is frequently out of stock for years at a time until a manufacturer decides to run a new batch.
.22 WRF vs .22 LR For Hunting
Hunting highlights the original purpose of the .22 WRF. In the early 1900s, the .22 WRF was highly prized by hunters because its 45-grain flat-nosed bullet hit much harder than early .22 LR loads, cleanly killing squirrels, rabbits, and raccoons without ruining edible meat. If a hunter owns a functional .22 WRF rifle today, it remains an excellent short-range small game cartridge.
However, the .22 LR is universally preferred by modern hunters. The .22 LR offers a massive variety of specialized hunting ammunition, from quiet subsonic hollow points to hyper-velocity copper solids. The .22 LR delivers ample kinetic energy and superior accuracy at a distance, making it vastly more practical for a day in the woods than trying to source obsolete .22 WRF ammunition.
.22 WRF vs .22 LR For Target Shooting
For plinking, skills training, and recreational target shooting, the .22 LR is the undisputed champion. The combination of practically zero recoil, low noise, and incredibly inexpensive ammunition makes it the ideal choice for high-volume range sessions. Formal competitive shooting disciplines are structured entirely around the .22 LR cartridge.
The .22 WRF is poorly suited for modern target shooting. The ammunition is expensive and highly difficult to find at local retail stores. A shooter would quickly spend a significant amount of money during a casual afternoon of plinking with a .22 WRF compared to a .22 LR. The .22 WRF is strictly reserved for occasional nostalgia shoots with antique family heirloom rifles.
.22 WRF vs .22 LR For Beginners
For new shooters, the .22 LR stands as the absolute best choice. The complete absence of recoil and the very mild report prevent inexperienced shooters from developing a flinch response. A beginner can dedicate hours to mastering sight alignment, breathing, and trigger control without physical fatigue or heavy financial costs. The .22 LR enjoys massive rifle availability, allowing a beginner to choose from thousands of affordable models.
The .22 WRF is a very poor choice for a beginner simply because of logistical issues. A beginner will struggle to find ammunition and will pay a severe premium for it when they do find it. Furthermore, they would have to learn on a vintage firearm that likely lacks modern safety features and optics compatibility. The most practical recommendation is to learn the fundamentals strictly on a dedicated, modern .22 LR platform.
.22 WRF vs .22 LR Firearms
Firearm manufacturers support the .22 LR with a vast array of platforms. Consumers can select from bolt-action rifles, semi-automatic rifles, lever-action rifles, pump-action rifles, single-action revolvers, and semi-automatic pistols. The .22 LR market remains massive and universally accessible.
Firearms chambered specifically for the .22 WRF are entirely historical antiques. The cartridge was made famous by slide-action rifles like the Winchester Model 1890 and the Remington Model 121, as well as classic revolvers like the Colt Police Positive Target. Today, virtually no major manufacturer produces a new firearm chambered for the .22 WRF.
Can .22 WRF And .22 LR Use The Same Gun?
No, standard .22 WRF and .22 LR cartridges cannot be safely fired from the same gun chamber. The chamber dimensions specified for each cartridge are completely incompatible.
The .22 LR requires a chamber cut specifically for a narrow rimfire cartridge. The .22 WRF requires a wider and longer chamber. You cannot safely swap these cartridges in the same rifle under any circumstances.
It is worth noting that a .22 WRF cartridge can theoretically be fired inside a rifle chambered for the much longer .22 Winchester Magnum Rimfire (.22 WMR), as they share the same case width. However, this article is strictly comparing the .22 WRF to the .22 LR, and those two share no cross-compatibility whatsoever.
.22 WRF vs .22 LR Ammunition Compatibility
Ammunition compatibility is strictly determined by the exact cartridge name stamped on the barrel of the firearm.
- .22 WRF is not interchangeable with .22 LR.
- .22 LR is not interchangeable with .22 WRF.
If a shooter attempts to insert a .22 WRF into a standard .22 LR chamber, the bolt will not close because the .22 WRF case is significantly too wide. If a shooter drops a .22 LR into a .22 WRF chamber, it will drop in but fit very loosely. Firing a .22 LR inside a .22 WRF chamber is highly dangerous. The excessive space allows the thin brass casing of the .22 LR to split open upon firing, venting high-pressure gases and burning powder back toward the shooter. Always read the barrel stamping before loading any ammunition.

Manufacturer Data vs Independent Testing
When reviewing ballistics, readers must understand the difference between promotional manufacturer specifications and independent chronograph testing. Because the .22 WRF is a legacy cartridge, modern manufacturers like CCI load it very carefully to ensure the pressures remain safe for antique firearms that may be over a century old.
Independent chronograph testing provides a highly realistic baseline for actual field performance. When evaluating these older cartridges, independent testers frequently find that .22 WRF ammunition fired from vintage rifles matches the advertised 1,300 fps remarkably well. However, when comparing modern .22 LR ballistics to .22 WRF ballistics in real-world conditions, the .22 LR consistently outperforms the older round at extended ranges due to vastly superior bullet design. When sources provide conflicting figures for vintage rimfire cartridges, controlled independent testing through the exact barrel length of the consumer’s chosen firearm represents the most practical data source.
FAQs
What is the main difference between .22 WRF and .22 LR?
The main difference is the case size. The .22 WRF utilizes a wider and longer brass case that holds more powder, allowing it to push a heavier 45-grain bullet faster than standard .22 LR ammunition.
Is .22 WRF more powerful than .22 LR?
Yes, generally. A factory .22 WRF load generates roughly 169 foot-pounds of energy at the muzzle, which hits harder than standard-velocity .22 LR loads, though hyper-velocity .22 LR loads can match this power.
Which is faster, .22 WRF or .22 LR?
The .22 WRF is faster than standard .22 LR ammunition, operating around 1,300 feet per second. However, modern high-velocity and hyper-velocity .22 LR ammunition (like the CCI Stinger) can achieve much higher speeds, exceeding 1,600 feet per second.
Can a .22 WRF shoot .22 LR?
No. A .22 LR cartridge is significantly narrower than a .22 WRF chamber. Firing it will cause the .22 LR brass case to expand excessively and rupture, which is extremely dangerous.
Can a .22 LR shoot .22 WRF?
No. A .22 WRF cartridge is too wide to physically fit into a .22 LR chamber.
Are .22 WRF and .22 WMR the same?
No. The .22 WRF (Winchester Rimfire) is shorter and less powerful than the .22 WMR (Winchester Magnum Rimfire). However, the .22 WRF case was the direct blueprint used to design the modern .22 Magnum.
Which is cheaper to shoot?
The .22 LR is vastly cheaper. It generally costs between 6 and 12 cents per round, while the rare .22 WRF typically costs between 40 and 60 cents per round when it can be found.
Is .22 WRF still manufactured?
Yes, but in very limited quantities. Companies like CCI and Winchester occasionally run seasonal batches of .22 WRF to supply collectors who still shoot vintage rifles.
