The .223 Remington and its nearly identical twin brother, the 5.56x45mm NATO, need very little introduction. They represent one of the most common calibers in the U.S. Being the NATO standard, they are in use in various platforms around the world. The data to list the number of world-wide .223 users is surprisingly difficult to find. So what is the best 223 ammo?

Anyone who recalls the 2012 ammunition crisis can attest to the serious shortages of .223 ammunition on the market. Yes, there was a time when almost all ammunition was selling out instantly. Anything vaguely associated with the AR-pattern rifle was nowhere in sight. Let’s take a look at the reasons for the popularity of the AR-rifle platform, and find the best .223 ammo for practical use applications.

223 Ammo Quick Answer Box:

The .223/5.56 cartridge is one of the most popular ammo calibers in the world.

• What’s the difference between .223 and 5.56 ammo? The .223 and 5.56 cartridges share the same casing. The difference between the two cartridges is pressure. The 5.56 NATO round has a higher pressure load. A rifle chambered in 5.56 has a longer chamber to accommodate the pressure of the 5.56 NATO round.

• What are the benefits of an AR-15 rifle chambered in .223 Wylde? The .223 Wylde shares the same chamber angling as the 5.56. Allowing it to easily handle higher pressure 5.56 NATO cartridges. The .223 Wylde provides high accuracy benefits of the .223 Rem cartridge, while giving shooters flexibility with ammunition options.

• Should I shoot steel cased .223 ammo in my AR-15? Modern steel case ammo is non-corrosive. Shooting bi-metal jackets in an AR-15, in normal shooting conditions, won’t have any short-term negative effects on your rifling. However, testing has shown that shooting steel-cased ammo for extended periods of time, at high rates of fire, can cause your barrel rifling to wear at an accelerated rate. 

.223 Ammo History

Stoner’s AR History

Ironically, the AR-15 rifle, which was the brainchild of Eugene Stoner, came as the result of scaling down the AR-10 rifle. The AR-10, an oft sought after and highly prized variant of the AR-pattern rifle, actually came first. The AR-15 was a smaller caliber version of the AR-10. Its design was to meet engineering requirements put out by the U.S. Continental Army Command in 1957. The requirements stated the need for a .22 caliber bullet, which would remain supersonic at 500 yards. A very lightweight rifle can fire the bullet. The magazine had a 20 round capacity. The .223 Remington was eventually born and the rest is history. It was tailor-made for the eventual M-16 and all derivatives down the line. 

Bullet types and weights

Full Metal Jacket (FMJ)

The FMJ is the most common type of ammunition. It possesses relative ease of manufacturing and significantly lower materials cost than other types of bullets. By looking at popular ammo-type listings, we can easily see that FMJ rounds are the top 10 selling cartridges. Well, except for the .22 LRN. They mostly serve the same purpose. It is the least expensive cartridge to manufacture and acquire. Ideally, suited for target practice. The standard weights of FMJ target ammo in .223/5.56 are 55 and 62 grain, which are significant.

The lighter grain bullets best pair with higher rates of barrel twist like 1:8 and 1:9. The lowest common twist rate is 1:7, which also happens to be the M4 and M16-A2/A4 standard. Its most common use is with the heavier 62gr. M855 ‘green tip’ cartridge.

Hollow Points (HP)

The hollow point bullet is synonymous with personal and home defense scenarios. Unless you are planning on buying bulk steel-cased Russian ammo, these rounds are at the upper end of the price sheet. The unique manufacturing process for hollow-point bullets is more involved. This translates directly to the price, and to the availability on the market since demand is lower than that of FMJs.

HP ammo has bullet weights similar to the popular offerings of FMJ bullets. Since there isn’t much mass to remove to make the concave opening on a hollow point bullet, the bullet remains small and light. Displaying similar energy and ballistics to the FMJ.

Soft Points (SP)

Best suited as a hunting cartridge, SPs are still quite a popular choice for AR-15 owners. They offer expansion qualities much better than that of an FMJ. They even have more controlled expansion than a hollow point. The goal is to harvest meat or fur not obliterate it. The beauty of the soft point bullet, is that it is not subject to the drag found in HP ammo. The drag is caused by a cavity in the middle of a bullet. The ballistic coefficient of SP ammo is excellent, particularly in the form of a boat tail.

M855

M855 ammo is easily identified by its green tip, its “armor-piercing” capabilities have been greatly exaggerated by the media.

The infamous ‘green tip’ bullet, which all vets will recall with mixed emotions. A fervor for some, despise from others. The purists stand fast that all service rifles should start with something that says “.30”. There are many reasons that give this bullet reputation. A former tenant of the White House demonized it for being “armor-piercing”. They wanted it banned from citizen ownership as “common sense”.

I hate to break it to the uninformed author of that sentiment, but there is nothing new under the sun about the “armor-piercing” magic of the M855. The Soviets used “armor-piercing” ammunition with the 7.62X54R cartridge. The magnificent Mosin-Nagant fired it off. This rifle was functional and durable as hell. This rifle was a major player in several wars. The original corrosive-primed cartridges for the Mosin fired a steel-cored 148gr. bullet. Rather than using the soft lead core common to most bullets, the steel core acts as a spike. It is capable of penetrating thin steel and bi-metal armor. The M855 is nothing new. It’s a reused old concept for a newer application.

Ammo Recommendations 

Let’s get down to brass tacks and look at some of the different kinds of .223 ammo from the leading brands. Broken down by the best-specified uses.

Best Target Shooting / Match .223 Ammunition

When accuracy and target placement counts, the MOA performance of these cartridges is near the top. Load your magazines with this ammo for a competition, and the only person you’ll be competing against is yourself. 

Hornady Superperformance 5.56 55 Gr GMX

Born to scream, Hornady’s Superformance is designed to propel around 100 to 200fps faster than its peers, which is well over 3,000fps for a 55gr 5.56.

The GMX line is a design that employs a one-piece copper alloy. Other designs feature copper plating bonded to a lead core. The bullet has polymer capping This aids its ballistic coefficient of .270.

Federal Gold Medal Match 69 Gr

The bullet weight of Federal Gold Medal Match gives the ammo excellent ballistic coefficiency.

Ideally suited for barrels with a lower rate of twist, like the 1:7 and 1:8. The heavy 69gr Federal Gold Match is tailored for the AR geek who actually likes reading about ballistic co-efficiency. It’s a great choice for guys like me who make a family day out of going to the range. His adoring wife and kids get to hear about it, stuck in the minivan along the way. 

The Sierra MatchKing is a boat-tail design, which is synonymous with excellent aerodynamics. It yields a ballistic coefficient of 0.301 at a muzzle velocity of 2,950fps. The heavier weight resists the effects of wind better than lighter bullets. It also creates a longer, sleeker bullet in the process.

Best .223 Ammo for Training

Are you planning to engage a silhouette at 25 meters? Are you ready to get dirty and train like you fight? You don’t need to shell out the dough on the higher-priced stuff. Go with the stuff that goes ‘bang’ every time you pull the trigger and doesn’t say ‘match’ anywhere on it.

Wolf Gold .223 55 Gr

It’s easy to decide which wolf to feed when you’re shooting Wolf Gold at the range.

Wolf is an established budget Russian ammo brand, which shoots about as clean as a Mig flies. But it does shoot reliably and their Gold line is a step or two up from its steel cased stablemates. Taiwan is the manufacturer of .223 Wolf Gold line. In the same factory that makes ammo for the Taiwanese military. The 55gr FMJ performs as accurately as every other 55gr FMJ in .223, and offers a reloadable brass case.

PMC Bronze .223 55 Gr

Another budget-friendly ammunition, bulk PMC Bronze is a step up from the budget-priced competition. Offering a 55gr FMJ boat tail bullet, which leaves the tube at 3,200fps and 1,250 ft/lbs. Right on par with other 55gr .223 cartridges.

Federal LE Tactical TRU is a soft-point bullet with the expansion characteristics of a hollowpoint.

Well suited for any of the myriad M4 clones on the market, the TRU 55gr soft point is made specifically for semi-automatics. Read: AR-15s. The soft point offers the best advantages of both worlds. Ideally suited for patrol weapons with their excellent penetration and weight retention. Good expansion close to that of a hollow point.

Hornady 223 55 Gr SP

Hornady sells a nearly identical soft point as the Federal TRU. It weighs in at 55gr and offers the same quality as their higher-end products that you’ve come to expect. 

The Adaptable Cartridge

The .223 has proven to be an adaptable, reliable, and versatile caliber. It has a variety of loads ranging from lightning-fast varmint rounds, to antelope and deer rounds. The heavy boat-tails make for precision marksmanship and tactical sharpshooting. It is cheap, plentiful, and very useful to have around. You can sleep easy with an AR-15 loaded with dedicated tactical 77gr rounds standing watch. Any landowner is confident he can dispatch all forms of varmints with a healthy dose of .223 Remington.
