The AR-15 platform’s adaptability has produced more .22-caliber cartridge variants than any other action type. Among those designed specifically for long-range AR performance with heavy, high-BC bullets, three stand out as the most practically relevant options available today: the 22 ARC, 224 Valkyrie, and 22 Nosler. All three push .22-caliber projectiles past what the 223 Remington can achieve, all three run in standard AR-15 lowers, and all three have found audiences for varmint hunting, precision rifle competition, and long-range target work.
They are not interchangeable, and understanding why requires looking past muzzle velocity claims to the practical realities of build costs, component availability, feeding reliability, and where each cartridge genuinely excels versus where its weaknesses show.
The Engineering Background
22 ARC
Hornady introduced the 22 ARC in 2023 as the .22-caliber companion to the 6mm ARC. Like its 6mm sibling, it is based on the 6.5 Grendel case architecture – a short, relatively fat case designed for the AR-15 bolt face and optimized for high-BC heavy bullets. The 22 ARC was built from the start to run heavy .224-inch projectiles in the 75-90 grain range with high BCs, specifically for long-range precision from AR-15 platforms. It launched with Hornady factory ammunition and factory reloading data simultaneously, which meant handloaders could begin developing loads immediately rather than relying on community data.
For the full technical guide, see our 22 ARC complete guide and the dedicated 22 ARC handloader’s technical guide.
224 Valkyrie
Federal introduced the 224 Valkyrie in 2017, necking down the 6.8 SPC case to accept .224-inch bullets. The original design brief was clear: push 90-grain high-BC bullets at 2,700 fps from an AR-15, remaining supersonic at 1,300 yards. It achieved those ballistics on paper and in initial testing. The problem was component availability – 224 Valkyrie brass proved inconsistent in supply and quality from some sources, factory ammunition variety contracted after the initial launch excitement, and the cartridge developed a reputation for load sensitivity that frustrated handloaders who compared notes online.
By 2026, the 224 Valkyrie occupies a somewhat reduced position: still commercially supported, still capable, but without the momentum it had at launch. For complete specifications, see our 224 Valkyrie complete guide.
22 Nosler
Nosler introduced the 22 Nosler in 2017 with a different approach from the Valkyrie. Rather than chasing the heaviest possible bullets, Nosler designed a rebated-rim case with 25% more capacity than the 223 Remington, specifically to push lighter 55-77 grain bullets at much higher velocities – approaching 22-250 Remington performance from an AR-15 platform. The rebated rim fits the standard AR-15 bolt face, requiring only a barrel and magazine change. It reached 3,100-3,300 fps with 55-grain bullets – genuine performance numbers.
The limitation has always been component availability. Nosler controls the brass supply, and it has never been as freely available as standard 223 Rem, 5.56, or even 6mm ARC brass. For specifications and ballistics, see the 22 Nosler complete guide.
Technical Characteristics
| Characteristic | 22 ARC | 224 Valkyrie | 22 Nosler |
|---|---|---|---|
| Bullet Diameter (inches) | 0.224 | 0.224 | 0.224 |
| Case Length (inches) | ~1.368 | 1.600 | 1.760 |
| Parent Case | 6.5 Grendel | 6.8 SPC | Proprietary rebated rim |
| Bolt Face | 6.5 Grendel (.440″) | 6.8 SPC (.422″) | Standard AR-15 (.378″) |
| Typical Muzzle Velocity (fps) | 2,750 (80 gr) | 2,675 (88 gr) | 2,950 (77 gr) |
| Typical Muzzle Energy (ft-lbs) | 1,343 (80 gr) | 1,397 (88 gr) | 1,486 (77 gr) |
| Max Pressure – SAAMI (PSI) | 62,000 | 55,000 | 62,000 |
The bolt face difference is the most practically important hardware distinction. The 22 ARC uses the 6.5 Grendel bolt face – the same bolt used by the 6mm ARC, which means an AR-15 already set up for 6mm ARC only needs a barrel change to run 22 ARC. The 224 Valkyrie requires the 6.8 SPC bolt face – a different part. The 22 Nosler uses the standard .223/5.56 bolt face, which is the broadest compatibility of the three.
Ballistics Comparison
All data uses 20-inch barrels, zeroed at 200 yards, standard conditions: 59°F, sea level.
Trajectory
| Distance (yards) | 22 ARC 80gr ELD-M | 224 Valkyrie 88gr ELD-M | 22 Nosler 77gr RDF |
|---|---|---|---|
| 0 | -1.5 | -1.5 | -1.5 |
| 100 | +1.7 | +1.9 | +1.5 |
| 200 | 0.0 | 0.0 | 0.0 |
| 300 | -7.5 | -8.2 | -6.8 |
| 400 | -22.0 | -24.0 | -19.5 |
| 500 | -42.0 | -45.0 | -38.0 |
The 22 Nosler’s higher muzzle velocity produces the flattest trajectory to 500 yards. The 22 ARC and 224 Valkyrie are within 3 inches of each other at 500 yards – a difference that matters in competition but is largely academic for varmint hunting where ranging precision matters more than cartridge ballistics.
Energy Retention
| Distance (yards) | 22 ARC 80gr | 224 Valkyrie 88gr | 22 Nosler 77gr |
|---|---|---|---|
| 0 (muzzle) | 1,343 | 1,397 | 1,486 |
| 200 | 1,030 | 1,053 | 1,100 |
| 300 | 875 | 875 | 920 |
| 500 | 618 | 608 | 657 |
Energy retention at 500 yards is close enough between all three that it is not a practical distinguishing factor for varmint hunting. All three maintain adequate energy for ethical kills on prairie dogs and coyotes to 500 yards.
Wind Drift
In a 10 mph full-value crosswind, zeroed at 200 yards:
| Distance (yards) | 22 ARC 80gr | 224 Valkyrie 88gr | 22 Nosler 77gr |
|---|---|---|---|
| 300 | 9.5″ | 10.5″ | 8.5″ |
| 500 | 22″ | 25″ | 20″ |
| 800 | 55″ | 62″ | 51″ |
The 22 Nosler’s velocity advantage reduces wind drift at moderate ranges. The 22 ARC’s higher-BC 80-grain bullet competes well at extended ranges despite lower velocity, because BC matters more than velocity for wind resistance once bullets are in flight. The 224 Valkyrie’s 88-grain ELD-M has an excellent G1 BC (0.547) but the somewhat lower velocity from the 6.8 SPC case leaves it marginally behind the other two.

Head-to-Head Summary
| Category | 22 ARC | 224 Valkyrie | 22 Nosler | Winner |
|---|---|---|---|---|
| Muzzle velocity (standard load) | 2,750 fps | 2,675 fps | 2,950 fps | 22 Nosler |
| Trajectory (drop at 500 yds) | -42″ | -45″ | -38″ | 22 Nosler |
| Wind drift (10 mph at 500 yds) | 22″ | 25″ | 20″ | 22 Nosler |
| Bolt face compatibility | 6.5 Grendel | 6.8 SPC | Standard .223/5.56 | 22 Nosler |
| Magazine feeding reliability | Good | Good | Excellent | 22 Nosler |
| Factory ammo availability | Good (growing) | Good | Fair (limited) | 22 ARC/Valkyrie |
| Brass availability | Good | Good | Limited | 22 ARC/Valkyrie |
| Component variety | Good | Good | Fair | 22 ARC/Valkyrie |
| Reloading data available | Excellent | Good | Good | 22 ARC |
| Build cost | Moderate | Moderate | Moderate | Draw |
| Long-term platform support | Strong | Moderate | Uncertain | 22 ARC |
| Heavy bullet capability (75+ gr) | Excellent | Excellent | Moderate | 22 ARC/Valkyrie |
Recoil
All three cartridges produce mild recoil in AR-15 platforms. The differences are real but not practically significant.
| Cartridge | Load | Recoil (ft-lbs, 7-lb rifle) |
|---|---|---|
| 22 ARC | 80 gr @ 2,750 fps | ~5.5 |
| 224 Valkyrie | 88 gr @ 2,675 fps | ~6.0 |
| 22 Nosler | 77 gr @ 2,950 fps | ~6.5 |
| 223 Remington | 55 gr @ 3,240 fps | ~4.0 |
The 22 Nosler’s higher velocity adds a slightly snappier impulse compared to the other two, but all three remain comfortable for all-day shooting without a muzzle brake. Any of these can be suppressed with appropriate equipment for even milder operation.
Accuracy
The accuracy potential of all three cartridges in properly built AR-15s is excellent. The differences in the field are more about ammunition consistency and load development than inherent cartridge accuracy capability.
22 ARC benefits from Hornady’s careful attention to factory load quality and the extensive published reloading data available at launch. Out of the box, quality 22 ARC factory loads in a quality AR produce 0.5-0.75 MOA groups at 100 yards. Handloads tuned to a specific barrel can push this to 0.3-0.5 MOA. The cartridge’s Grendel case heritage – a BR-derived design with proven accuracy credentials – contributes to its consistency. For load development guidance, see our develop a custom 22 ARC load guide.
224 Valkyrie showed early on that bolt-action rifles extract its accuracy potential more consistently than AR-15 gas guns. The semi-auto gas system introduces variables that can widen groups compared to a single-shot or bolt action. In a well-tuned AR-15 with a quality barrel, 0.75-1.0 MOA is a realistic expectation. The load sensitivity issues that generated early reputation problems largely traced to specific barrel and load combinations rather than the cartridge itself – a well-matched combination produces good results.
22 Nosler produces excellent accuracy in AR-15 platforms with appropriate components. The standard AR bolt face compatibility means any quality 1:8 or 1:7 twist AR barrel is a potential host. Groups of 0.5-0.75 MOA with optimal loads are achievable. The cartridge’s limitation for accuracy with the heaviest high-BC bullets is the twist rate question – original 22 Nosler data was developed around lighter 55-77 grain bullets, and the 1:8 twist that works well with these does not provide optimal stability for the longest 80-90 grain projectiles.
Applications
Long-Range Varmint Hunting
Best choice: 22 ARC or 22 Nosler depending on bullet weight preference
For coyote and prairie dog hunting at 300-500 yards where consistent component supply matters for a high-volume shooter, the 22 ARC and 22 Nosler both serve well. The 22 ARC with an 80-grain Hornady ELD-X provides reliable expansion across the full velocity range from close-range impacts to 500-yard arrivals. The 22 Nosler with lighter 55-64 grain varmint bullets produces more explosive terminal performance on small animals due to higher velocity, but requires being thoughtful about overpenetration on larger predators.
The 224 Valkyrie is capable in this role when properly loaded, but the relatively modest factory load variety and the need to develop handloads carefully make it a less convenient choice for hunters who prioritize the rifle being a tool rather than a project.
For hunters specifically focused on predator calling at moderate ranges, see our 22 ARC for long-range handloading guide.
Precision Rifle Competition
Best choice: 22 ARC
In AR-class divisions of PRS-format matches, the 22 ARC’s combination of high-BC heavy bullets, reliable factory ammunition, and the growing community of load development data makes it the best current choice for competitive shooting. The Hornady ELD-M 75-grain and 80-grain Hornady A-Tip Match are the benchmark competition bullets. Sierra Tipped MatchKing and Berger Hybrid Target in appropriate weights are also well-suited.
For steel-target work at 600-1,000 yards, the 22 ARC’s BC-driven wind resistance is the relevant advantage. The 22 Nosler’s velocity edge matters more at shorter ranges; the 22 ARC’s BC advantage compounds with distance.
Reloading Accessibility
Best choice: 22 ARC
All three cartridges reward handloading – factory ammunition costs enough that reloading pays back quickly at moderate volume. The 22 ARC benefits from Hornady’s complete published data suite, quality brass from multiple sources, and the existing 22 ARC handloading ecosystem on this site. For starting points, see our your first 22 ARC handload guide, top 5 powders for 22 ARC, and best bullets for your 22 ARC.
The 224 Valkyrie has good brass availability and solid handloading support from Federal and Hornady data. The 22 Nosler’s brass supply is the constraint – Nosler controls production, and the market has experienced periodic shortages that interrupt load development continuity.
Reloading Essentials
Primers
All three cartridges use Small Rifle primers. Benchrest primers (CCI BR-4, Federal 205M) are the competition standard. Standard Small Rifle (CCI 400) works well for hunting loads and general practice.
Powders
The three cartridges have overlapping but distinct powder preferences due to their different case capacities.
22 ARC (smaller Grendel-based case) works best with medium-burn powders:
| Powder | Bullet Weights (gr) | Notes |
|---|---|---|
| Hodgdon Varget | 75-88 | Temperature stable; most popular |
| Hodgdon H4895 | 70-80 | Clean; consistent |
| Vihtavuori N135 | 70-80 | Temperature stable; clean |
| Alliant Reloder 15 | 75-88 | Good velocity nodes |
| IMR 8208 XBR | 70-88 | Temperature stable; wide range |
224 Valkyrie (6.8 SPC-based, more capacity) works best with medium-to-slower powders:
| Powder | Bullet Weights (gr) | Notes |
|---|---|---|
| Hodgdon Varget | 75-90 | Most data available |
| Alliant Reloder 16 | 80-90 | Temperature stable |
| Hodgdon H4895 | 70-88 | Versatile |
| Vihtavuori N133 | 70-80 | Lighter bullets |
| Hodgdon CFE 223 | 75-88 | Copper fouling reducer |
22 Nosler (larger capacity, runs faster powders for lighter bullets):
| Powder | Bullet Weights (gr) | Notes |
|---|---|---|
| Hodgdon H335 | 55-70 | Designed for this application |
| Hodgdon Varget | 62-77 | Heavier bullets |
| Alliant AR-Comp | 69-77 | AR gas system optimized |
| Vihtavuori N133 | 55-70 | Temperature stable |
| IMR 8208 XBR | 55-77 | Wide bullet range |
Always verify charge weights against current published data before loading. Begin at minimum charges and work up carefully.

Component Availability and Build Costs
This is where the three cartridges diverge most practically.
22 ARC: Hornady produces brass, factory ammunition (both hunting and match), and published reloading data. The case is based on the 6.5 Grendel family, so tooling exists. Quality brass from multiple sources is available. Uppers from PSA, Aero Precision, and custom barrel makers are readily sourced. Component sourcing guidance is at our where to buy 22 ARC components guide.
224 Valkyrie: Federal, Hornady, and Nosler all produce factory loads. Brass is commercially available from multiple sources. The cartridge’s base level of commercial support has stabilized after the post-launch contraction, though it does not have the same forward momentum as the 22 ARC. Uppers and barrels are widely available, including inexpensive PSA options.
22 Nosler: Nosler produces factory loads and controls the brass supply. The cartridge runs on the standard AR bolt face, which is the broadest hardware compatibility of the three – any quality 1:8 .224-inch barrel and standard AICS-compatible magazine is a potential build. Brass availability has been the persistent constraint, and the gap between 22 Nosler brass availability and the other two has not meaningfully closed.
The Decision
Choose the 22 ARC if:
- You want the best-supported new .22 AR cartridge for long-range precision and varminting
- You already have or plan to build a 6mm ARC – sharing a bolt face simplifies the build
- You prioritize heavy high-BC bullet performance with growing component access
- Long-term factory ammunition and component support matters to you
Choose the 224 Valkyrie if:
- You already have a Valkyrie setup and have learned its load preferences
- You want the heaviest available .22-caliber bullets (88-90 grains) at good velocities in an AR
- Budget matters and you are comfortable investing time in load development
- You shoot primarily from bolt-action rifles where the cartridge’s accuracy potential is fully accessible
Choose the 22 Nosler if:
- Maximum muzzle velocity from an AR-15 with the standard bolt face is the priority
- You primarily shoot lighter 55-70 grain bullets for close-to-moderate range varminting
- You have confirmed brass availability from your preferred supplier
- You want the simplest hardware conversion from a standard .223/5.56 build
For a broader look at how these cartridges relate to each other and the wider .22-caliber precision landscape, see our 22 ARC vs 6mm ARC comparison and the 22 ARC vs 224 Valkyrie vs 22 Nosler detailed guide.
Conclusion
The 22 ARC, 224 Valkyrie, and 22 Nosler each make sense in specific contexts. The 22 Nosler shoots the flattest at moderate ranges and uses the most common hardware. The 22 ARC provides the best balance of long-range BC performance, growing component support, and handloading resources. The 224 Valkyrie remains capable for shooters already invested in the platform.
For anyone starting fresh in 2026, the 22 ARC is the most defensible choice for a long-range precision AR build – it has Hornady’s full commercial support, a growing community knowledge base, and the engineering benefit of lessons learned from earlier .22 AR long-range cartridges. The 22 Nosler suits velocity-first varmint hunters who confirm brass is available before committing. The Valkyrie serves existing owners who have sorted out their load requirements and want to keep shooting what works.
