The 223 Remington was standardized by Remington in 1964 as the civilian counterpart to the military 5.56x45mm NATO cartridge. It is the most widely used centerfire rifle cartridge in North America by volume, chambered in more AR-15 and bolt-action rifles than any other round. Its combination of low recoil, flat trajectory, broad component availability, and genuine accuracy at moderate ranges has made it the default choice for coyote hunters, prairie dog shooters, and AR-15 owners across the country.
Chamber compatibility note: The 223 Remington and 5.56x45mm NATO are similar but not identical. A 5.56x45mm chamber has a longer throat (freebore) than a 223 Remington chamber. Military 5.56 ammunition can be fired safely in a 5.56 chamber or a .223 Wylde chamber; it should not be fired in a standard 223 Remington chamber due to higher pressure from the longer bullet seating against a shorter throat. 223 Remington ammunition is safe in any of the three chambers. If your rifle’s chamber is uncertain, use 223 Remington commercial ammunition.
The 223 Remington is a varmint and predator cartridge that doubles as a coyote hunting round and an AR-15 competition cartridge. It is not a big game cartridge. The original article on this page claimed the Barnes TTSX is “correct for elk or larger game” and that AccuBond produces “ethical harvests up to 700 yards for big game” from the 223 Remington. This is incorrect – the 223 Remington produces a maximum of 1,313-1,834 ft-lbs at the muzzle depending on load, well below the minimum required for elk at any distance.

Core Ballistic Parameters
| Load | MV | BC (G7) | Muzzle Energy |
|---|---|---|---|
| 55 gr Hornady V-MAX | 3,240 FPS | 0.143 | 1,282 ft-lbs |
| 62 gr FMJ (M855) | 3,100 FPS | 0.151 | 1,323 ft-lbs |
| 69 gr Sierra MatchKing | 2,950 FPS | 0.196 | 1,335 ft-lbs |
| 77 gr Sierra MatchKing | 2,750 FPS | 0.222 | 1,294 ft-lbs |
All data below uses a 100-yard zero, 1.5-inch sight height, 59°F, sea level. The 223 Remington is a standard-velocity cartridge used at typical hunting and target distances. A 100-yard zero is the practical standard for most 223 Remington applications.
Bullet Drop (100-Yard Zero)
| Range (yards) | 55 gr V-MAX | 62 gr M855 | 69 gr SMK | 77 gr SMK |
|---|---|---|---|---|
| Muzzle | -1.5 | -1.5 | -1.5 | -1.5 |
| 100 | 0.0 | 0.0 | 0.0 | 0.0 |
| 200 | -3.4 | -3.7 | -4.0 | -4.7 |
| 300 | -12.8 | -13.9 | -15.0 | -17.5 |
| 400 | -29.5 | -32.0 | -34.6 | -40.5 |
| 500 | -56.0 | -61.0 | -66.0 | -77.5 |
| 600 | -93.5 | -102.0 | -110.5 | -130.0 |
| 700 | -144.5 | -158.0 | -171.5 | -202.0 |

| 1,000 | -402.0 | -443.5 | -485.0 | -576.0 |
Drop in inches. Zero at 100 yards.
With a 100-yard zero, the 223 Remington 55-grain V-MAX is 3.4 inches low at 200 yards – manageable for an experienced coyote hunter who holds slightly high. At 300 yards it drops 12.8 inches, requiring deliberate holdover. The 77-grain MatchKing shows substantially more drop at every distance due to its lower starting velocity – 17.5 inches at 300 yards versus 12.8 inches for the 55-grain load.
The drop difference between loads is the largest of any cartridge covered in these ballistics articles because the velocity spread between 55-grain at 3,240 FPS and 77-grain at 2,750 FPS is 490 FPS – a significant gap in the same bore diameter. Hunters who switch between varmint and competition loads need separate holdover cards for each.
Wind Drift – 10 MPH Full-Value Crosswind
| Range (yards) | 55 gr V-MAX | 62 gr M855 | 69 gr SMK | 77 gr SMK |
|---|---|---|---|---|
| 100 | 0.8 | 0.8 | 0.7 | 0.6 |
| 200 | 3.3 | 3.2 | 2.8 | 2.5 |
| 300 | 7.6 | 7.4 | 6.5 | 5.8 |
| 400 | 13.8 | 13.5 | 11.8 | 10.5 |
| 500 | 22.2 | 21.7 | 18.9 | 16.8 |
| 600 | 32.8 | 32.0 | 27.9 | 24.8 |
| 700 | 45.8 | 44.8 | 38.9 | 34.6 |
| 800 | 62.0 | 60.6 | 52.7 | 46.9 |
| 900 | 81.0 | 79.2 | 68.8 | 61.3 |
| 1,000 | 103.0 | 100.7 | 87.7 | 78.1 |
Drift in inches. Half-value crosswind = divide by 2.
The 77-grain MatchKing drifts 24.9 fewer inches than the 55-grain V-MAX at 1,000 yards – a dramatic difference that explains why NRA High Power and precision rifle competitors standardized on the 77-grain class for 600-800 yard shooting. At 500 yards the gap is 5.4 inches, which in a 5 MPH wind represents the difference between a center hit and a near-miss on a coyote-sized target.
The 223 Remington’s wind sensitivity is its primary limitation at extended ranges. At 500 yards in a 10 MPH crosswind, even the best load (77-grain SMK at 16.8 inches) requires accurate wind reading to hit a coyote. The 55-grain V-MAX at 22.2 inches of drift means a 3 MPH wind-reading error at 500 yards costs over 6 inches – outside a coyote’s vital zone.
Velocity Retention
| Range (yards) | 55 gr V-MAX | 62 gr M855 | 69 gr SMK | 77 gr SMK |
|---|---|---|---|---|
| Muzzle | 3,240 | 3,100 | 2,950 | 2,750 |
| 100 | 2,934 | 2,812 | 2,712 | 2,545 |
| 200 | 2,645 | 2,535 | 2,482 | 2,347 |
| 300 | 2,371 | 2,270 | 2,259 | 2,156 |
| 400 | 2,112 | 2,017 | 2,044 | 1,973 |
| 500 | 1,867 | 1,776 | 1,836 | 1,797 |
| 600 | 1,637 | 1,549 | 1,636 | 1,628 |
| 700 | 1,422 | 1,337 | 1,445 | 1,466 |
| 800 | 1,225 | 1,143 | 1,264 | 1,312 |
| 900 | 1,050 | 979 | 1,098 | 1,168 |
| 1,000 | 901 | 841 | 955 | 1,036 |
Velocity in FPS. Supersonic threshold approximately 1,340 FPS at sea level.
The 55-grain and 62-grain loads go transonic at approximately 775-825 yards. The 69-grain SMK crosses the threshold around 850-875 yards. Only the 77-grain SMK stays above 1,340 FPS past 900 yards, reaching 1,036 FPS at 1,000 yards.
The claim in the original article and in many marketing materials that the 223 Remington “maintains supersonic performance well beyond 1,000 yards” applies only to the 77-grain MatchKing – and even then, 1,036 FPS provides marginal supersonic margin with high wind drift (78 inches in 10 MPH wind at 1,000 yards). For the lighter varmint loads, practical accuracy ceiling is 700-750 yards.
At altitude (5,000+ feet), supersonic range extends by 50-75 yards for all loads due to reduced air density – relevant for western mountain varmint shooting.
Energy Retention
| Range (yards) | 55 gr V-MAX | 62 gr M855 | 69 gr SMK | 77 gr SMK |
|---|---|---|---|---|
| Muzzle | 1,282 | 1,323 | 1,335 | 1,294 |
| 100 | 1,051 | 1,087 | 1,127 | 1,108 |
| 200 | 854 | 884 | 945 | 943 |
| 300 | 686 | 709 | 782 | 796 |
| 400 | 544 | 560 | 640 | 666 |
| 500 | 425 | 434 | 516 | 551 |
| 600 | 327 | 330 | 410 | 453 |
| 700 | 247 | 246 | 320 | 367 |
| 800 | 183 | 180 | 245 | 295 |
| 900 | 134 | 132 | 185 | 233 |
| 1,000 | 99 | 97 | 140 | 183 |
Energy in ft-lbs.
The energy table makes the 223 Remington’s honest limits clear. The 55 and 62-grain loads cross below 1,000 ft-lbs at approximately 115-135 yards. The 69-grain SMK crosses below 1,000 ft-lbs around 165 yards. The 77-grain SMK holds above 1,000 ft-lbs to approximately 140 yards.
For deer (1,000 ft-lbs practical minimum), the 223 Remington is below the threshold before 200 yards with all loads. It is legal for deer hunting in many states but energetically inadequate for reliable ethical kills past 100-125 yards. For elk, the cartridge never reaches the 1,500 ft-lbs threshold – the best load (69-grain SMK) produces only 1,335 ft-lbs at the muzzle.
Terminal Performance Profiles
Hornady V-MAX 55 gr
Construction: Polymer tip with thin expanding jacket, lead core. The most common 223 Remington varmint load in factory ammunition.
Terminal behavior: Fragments violently at 223 Remington velocities. At 3,240 FPS the V-MAX produces explosive fragmentation with penetration of 6-10 inches and a large temporary cavity. On prairie dogs and ground squirrels this is immediately effective. On coyotes from broadside shots, the V-MAX produces reliable kills at distances where impact velocity exceeds 2,200 FPS (approximately 425 yards).
Hunting application: Varmints to 500 yards, coyotes to 400 yards. The 55-grain V-MAX is the standard reference varmint load for the 223 Remington – widely available, accurate in most barrels, and produces the explosive effect varmint hunters seek. Not appropriate for deer – energy is below 1,000 ft-lbs before 150 yards and penetration depth is insufficient for reliable access to deer vitals.
More details: Hornady V-MAX bullet profile
62 gr FMJ (M855 / Green Tip)
Construction: Full metal jacket steel-core penetrator. The military M855 load. Not an expanding bullet – designed for penetration through barriers, not controlled expansion on game.
Terminal behavior: The M855 does not expand reliably in soft tissue at hunting velocities. At close range where the bullet is still tumbling from barrel rifling, it can yaw and cause significant tissue disruption. At extended range where the bullet has stabilized, it often passes through soft tissue with a narrow wound channel. Performance is inconsistent and not appropriate for hunting application.
Application: Target practice and volume shooting. The M855/62-grain FMJ is the most cost-effective 223 Remington load for high-volume AR-15 training and practice. It is not a hunting load. In some jurisdictions, FMJ ammunition is prohibited for deer hunting even where the 223 Remington caliber is legal – check local regulations.

Sierra MatchKing 69 gr
Construction: Open-tip match (OTM) bullet with thin precision-formed jacket. Designed for accuracy, not controlled terminal expansion.
Terminal behavior: At 223 Remington velocities, the 69-grain SMK can produce yaw and tumble in soft tissue at close range, causing significant disruption. At longer ranges where impact velocity is below 2,400 FPS, terminal performance becomes inconsistent. The SMK was not designed for hunting and its terminal performance is not reliable for ethical use on game.
Competition application: The 69-grain SMK is the standard load for NRA High Power competition at 200-300 yards in the 223 Remington. Its superior BC to the 55-grain varmint loads produces noticeably better wind resistance at 300-600 yards. For competitive shooters who want the best performance from a 223 Remington without switching to the 77-grain class, the 69-grain SMK is the step up.
More details: Sierra MatchKing bullet profile
Sierra MatchKing 77 gr
Construction: Heavy-for-caliber OTM with high BC. Requires a 1:8 or faster twist rate for stabilization – will not stabilize in the standard 1:12 twist common in older 223 Remington rifles.
Terminal behavior: Same inconsistent terminal performance as the 69-grain SMK – a match bullet, not a hunting bullet. At close-range high-velocity impacts in the 223 Remington, the thin jacket can produce dramatic disruption; at longer ranges terminal performance is unreliable for ethical hunting.
Competition application: The 77-grain SMK is the benchmark competition load for the 223 Remington at 600-800 yards. Its G7 BC of 0.222 produces the best wind resistance of any widely available .224-inch bullet at this weight, and it remains supersonic past 900 yards – the longest supersonic range of the four loads in this article. For Service Rifle competition at 600 yards and Long Range competition at 800+ yards, the 77-grain SMK has been the standard for decades.
Twist rate requirement: The 77-grain SMK requires a minimum 1:8 twist for reliable stabilization. Rifles with 1:9 twist may or may not stabilize it depending on barrel temperature and atmospheric conditions; 1:12 twist will not stabilize it. Many modern AR-15 barrels are 1:8, but verify before loading.

Hornady ELD-M 75 gr
Construction: Polymer tip match bullet with Heat Shield, high-BC design for .224-inch bore. Hornady’s premium match offering at this caliber weight.
Terminal behavior: Like all match bullets, the ELD-M is not designed for controlled hunting expansion. At close-range high-velocity impacts it expands, but inconsistently. It is not appropriate for hunting use.
Competition application: The ELD-M 75-grain offers competitive BC with the Sierra 77-grain SMK in a polymer-tip design that provides slightly better long-range BC retention. In well-built 223 Remington barrels with 1:8 twist, sub-0.5 MOA groups are achievable. For competitors who prefer polymer-tip bullets for their BC advantage at extreme range, the ELD-M is the alternative to the SMK.
Coyote application: Some hunters use the 75-grain ELD-M on coyotes at close to moderate ranges (inside 300 yards) where impact velocity is above 2,500 FPS and the thin jacket provides adequate tissue disruption. Results are inconsistent – the ELD-M is a better competition bullet than it is a coyote bullet. Use the V-MAX or a dedicated coyote load for predator hunting.

Practical Range Recommendations
Prairie dogs and small varmints – 55-grain V-MAX to 500 yards. Inside 300 yards the trajectory with a 100-yard zero requires minimal holdover on most prairie dog shots.
Coyotes – 55-grain V-MAX or 69-grain SMK to 375-400 yards. Past 400 yards, wind drift in a 10 MPH crosswind exceeds 12-14 inches – requiring accurate wind reading to hit a coyote reliably. A practical self-imposed limit of 350 yards on coyotes in variable wind is appropriate for most hunters. In calm conditions an experienced shooter can stretch to 450-475 yards.
Deer – not recommended. The 223 Remington drops below 1,000 ft-lbs before 200 yards with all loads. Where legal for deer hunting, restrict shots to inside 125 yards with quality expanding bullets (not FMJ, not match bullets) on broadside shots only. A 243 Winchester or 7mm-08 Remington in the same AR or bolt-action platform provides substantially better margin for deer.
Competition – 69-grain SMK for 300-600 yards, 77-grain SMK for 600-800 yards. Both require 1:8 or 1:9 twist for stabilization.
Frequently Asked Questions
What is the difference between 223 Remington and 5.56x45mm NATO? The cartridges are dimensionally similar but the 5.56x45mm NATO operates at higher pressure and is loaded to higher specifications than 223 Remington. The critical difference is chamber design: a 5.56 chamber has longer freebore (throat) than a 223 Remington chamber. Firing 5.56 military ammunition in a 223 Remington chamber can produce elevated pressure because the bullet engages the rifling sooner. 223 Remington ammunition is safe in a 5.56 or .223 Wylde chamber. The .223 Wylde chamber is a hybrid design that accepts both cartridges safely with good accuracy.
Is the 223 Remington legal for deer hunting? In many states, yes – but it is marginal. Most states that allow it require expanding bullets (FMJ is typically prohibited for deer). Energy drops below 1,000 ft-lbs before 200 yards with all loads. Hunters who use the 223 Remington for deer should restrict shots to inside 125 yards on broadside shots with quality expanding bullets like the Nosler AccuBond or Barnes TSX in 62-70 grain weights. Shot placement requirements are more demanding than with larger calibers.
What twist rate does the 223 Remington need for different bullet weights? The 1:12 twist handles 55-grain and lighter bullets well. The 1:9 twist stabilizes bullets up to 69-grain reliably. The 1:8 twist is required for reliable stabilization of 77-grain and heavier bullets. Many AR-15 factory barrels are 1:9, which limits the 77-grain class. Modern factory barrels for precision AR-15s are commonly 1:8. Bolt-action rifles vary; check your specific barrel before loading heavy-for-caliber bullets.
How far is the 223 Remington effective on coyotes? 400 yards in calm conditions with the 55-grain V-MAX or 69-grain SMK and good wind reading. In a 10 MPH crosswind, a 3 MPH estimation error at 400 yards moves the bullet 4 inches – inside a coyote’s vital zone but with little margin. A practical self-imposed limit of 350 yards in variable wind conditions is appropriate for most hunters. At 500 yards in any crosswind, consistent hits require skilled wind reading and precise holdover.
Can I use the 223 Remington for hogs? On smaller hogs (under 150 pounds) with bonded expanding bullets inside 200 yards, yes. The 62-grain Barnes TSX or similar bonded lead-free load provides adequate penetration for broadside shots on hogs inside 150 yards. On large boars with the shoulder shield, energy and penetration are both marginal – the 223 Remington can wound without killing. A 6.5 Grendel or larger caliber AR-15 chambering is more appropriate for reliable hog harvesting.
What is the 223 Remington’s barrel life? 3,000-5,000 rounds before accuracy loss with standard loads. This is substantially longer than the 22-250 Remington and comparable to the 308 Winchester. The 223 Remington’s moderate powder charge (approximately 24-26 grains) and standard pressure produce much less throat erosion than overbore varmint cartridges. High-volume AR-15 shooters who fire 5,000+ rounds per year will go through a barrel in 1-2 seasons; hunters who fire 500 rounds per year have a decade of accurate shooting from a quality barrel.
Editorial note: This article was originally published in November 2025 and revised in April 2026. The revision corrected the zero to 100 yards per site standard for standard cartridges, recalculated all drop and wind drift tables for 100-yard zero with accurate load-specific data using G7 BC values, corrected the energy table (original 69 gr showed 1,627 ft-lbs muzzle energy which requires 2,310 FPS – the 69 gr SMK exits at 2,950 FPS producing 1,335 ft-lbs; original 77 gr showed 1,834 ft-lbs requiring 2,318 FPS – it exits at 2,750 FPS producing 1,294 ft-lbs), removed dangerous claims about the Barnes TTSX being appropriate for elk from the 223 Remington, replaced the Nosler AccuBond profile (inappropriate for this caliber at these energies) with Hornady ELD-M 75 gr as a more practical fifth bullet, added the 5.56/223 chamber compatibility warning, added velocity retention table with twist rate requirements for heavy bullets, added explicit deer and hog hunting limitations, and added FAQ.
