Probably the most popular centerfire rifle round in the Western Hemisphere is the .223 Remington and its metric match, the 5.56x45mm. Though many folks use “.223 Rem” and “5.56×45″ interchangeably, there are some meaningful differences in specifications for the original .223 Rem and the 5.56x45mm cartridge, as adopted by the U.S. military and NATO armies. The default chamber throats are slightly different and the .223 Rem is rated at 55,000 PSI vs. 62,366 PSI for the 5.56x45mm.*
.223 Rem vs 5.56x45mm — Key Differences
There is a truly outstanding, very thorough article on the subject, published by LuckyGunner.com.** This involved extensive testing, with pressure monitors, of 5.56x45mm ammo in .223 Rem chambers. Those tests revealed the peak pressures. Here is one of the ammo test charts:
NOTE: “The observed chamber pressure for Federal XM855 5.56mm ammunition in a .223 Rem chamber exceeded .223 maximum pressures, but not by a massive amount. The ninth shot (the red line) was an underpowered cartridge which exhibited significantly lower velocity and pressure than the other rounds, so it was excluded from the average velocity and pressure numbers for this chamber.”
And if you’re curious, LuckyGunner also fired .223 Rem ammo in a 5.56x45mm NATO-chambered AR15 rifle. As you would expect, the peak pressures were significantly lower, but the .223 Rem ammo still cycled the semi-auto AR-platform rifle perfectly well:
UltimateReloader.com Explains .223 Rem vs. 5.56x45mm
To explain the key differences between the .223 Rem and 5.56x45mm cartridges our friend Gavin Gear of UltimateReloader.com has created a very thorough 12-minute video. This covers the cartridge specifications and explains key considerations for hand-loaders. Gavin also addresses the oft-asked question “Can I shoot 5.56x45mm ammo in my .223 Rem chamber?” Gavin’s video is definitely worth watching. In fact, this is one of the most popular videos Gavin has ever created — it has been watched over 300,000 times on YouTube.
What Exactly Is the 5.56x45mm NATO Cartridge?
The 5.56×45mm NATO is a rimless bottle-necked intermediate cartridge family standardized by NATO with development work by FN Herstal. It consists of the SS109, SS110, and SS111 cartridges. Under STANAG 4172, it is a standard cartridge for NATO forces as well as many non-NATO countries.
Bullet diameter: 5.70 mm (0.224 in)
Maximum pressure (EPVAT): 430.00 MPa (62,366 psi)
Maximum pressure (SCATP 5.56): 380.00 MPa (55,114 psi)
Case length: 44.70 mm (1.760 in)
Rifling twist: 178 mm or 229 mm (1 in 7 in)
Parent case: .223 Remington (M193)
Ammo-Maker Federal Premium Compares .223 Rem and 5.56x45mm
Here is a video from ammo-maker Federal Premium explaining the difference between .223 Remington and 5.56x45mm NATO. Federal states that you may experience excessive pressures when firing a 5.56x45mm in a standard .223 Remington chamber:
One leading gunwriter has addressed the question of shooting 5.56x45mm ammo in .223 Rem chambers. He advocates caution (for more info, SEE pressure tests by LuckyGunner.com):
“I have received a slew of questions — many from first time AR-type rifle buyers — about the .223 Rem and the 5.56×45 mm NATO cartridges. Can I shoot 5.56×45 mm NATO in my .223 and vice-versa? Are these the same cartridge?
Externally, the two cartridge cases are identical. The main differences are that 5.56×45 mm NATO operates at a higher chamber pressure (about 60,000 PSI versus 55,000 PSI on the .223 Rem.) and the 5.56’s chamber is slightly larger than that of the .223 Rem. Also, the throat or leade is longer in the 5.56×45 mm chamber. What does this mean? You should not shoot 5.56×45 mm NATO out of a rifle that is chambered in .223 Rem. And be aware that some .223 Rem. ammunition will not reliably cycle through some AR-style .223 Rem. rifles, but it usually does. As a matter of fact, I have not encountered any difficulty with current .223 Rem. loads cycling through a 5.56 mm AR-style rifle.” – Mark Keefe, Editor, American Rifleman
* According to the official NATO proofing guidelines, the 5.56×45mm NATO case can handle up to 430.0 MPa (62,366 psi) piezo service pressure. The U.S. SAAMI lists Maximum Average Pressure (MAP) for the .223 Remington cartridge as 55,000 psi (379.2 MPa) piezo pressure with deviation of up to 58,000 psi (399.9 MPa). The chamber for military 5.56×45mm NATO has a longer throat prior to the bullet contacting the rifling which results in lower pressures when firing 5.56×45mm NATO ammunition. If 5.56×45mm NATO is used in rifles chambered for .223 Remington the bullet will be engraving the rifling when chambered. which can increase pressures past SAAMI Max levels. NOTE: The C.I.P. standards for the C.I.P. civilian .223 Remington chamber are much closer to the military 5.56×45mm NATO chamber.
** The full-length LuckyGunner article is well worth reading. It even provides specifications for a number of .223 Rem reamer types, and compares the original .223 Rem, the 5.56x45mm NATO, and the modern .223 Wylde chamberings.
Jerry Miculek — that name is synonymous with revolvers. But Jerry is also one heck of a rifleman, as he demonstrates in this video.
Three Shots Standing at 400 Yards in 4.37 Seconds
For those of us who usually shoot from the bench, hitting a silhouette target at 400 yards from an standing position (unsupported) would be a big challenge. Here Jerry Miculek makes it look easy.
In this video, Jerry hits not one but THREE c-zone targets at 400 yards. And — get this — he does this in under 4.4 seconds starting with his rifle laying on a support. It took Jerry two tries (on his first run he hit 2 out of 3 in 4.65 seconds). On the second attempt (see video starting at 2:19), it takes Jerry just 4.37 seconds to shoulder his rifle, aim, and fire three shots, each hitting a separate steel target. Wow. That’s truly remarkable. Most of us would need ten seconds (or more) just to get the scope on the first target.
Trust us folks, this ain’t easy. It takes remarkable marksmanship skills to shoot with this kind of precision at this kind of pace. As Jerry would say himself, “Not bad for an old guy who needs glasses”.

Looking for your first black rifle, i.e. an AR-platform semi-auto? Now is a great time to buy. Gunmakers stepped up AR production dramatically in 2015-2016, to satisfy high demand by citizens who feared that a Democratic Presidential victory would result in bans on semi-auto rifles. Well Hillary Clinton lost, so the panic buying ended. That means there is an over-supply of ARs at this time. So AR manufacturers are cutting prices and offering significant money-back rebates.
Perhaps the most attractive AR offers right now are the Bushmaster and DPMS Mid-Year Rebates. You can save $125.00 on the most popular Bushmaster and DPMS models. Bushmaster QRC rifles are $75 off, while the DPMS Oracle models (both .223 and .308) are $50 off.
You will want to act soon to qualify for these Mid-Year promotions. You have two more weeks to buy — Both Bushmaster and DPMS Rebate programs end July 31, 2018.
DPMS/Panther Arms makes a wide variety of rifles, including AR10-type rifles that handle the .308-Win family of cartridges. DPMS’s GII Series is an AR10 evolution with lighter weight and more AR15 parts interchangeability. DPMS claims the GII is “the lightest, most reliable, technically advanced .308 MSR”.

The Second Amendment Foundation (SAF) has filed a lawsuit against the California Department of Justice and Attorney General Xavier Becerra, seeking an injunction against the agency for failing and refusing to establish a properly functioning Internet-based firearms registration system.
Joining SAF in this legal action are the Calguns Foundation, Firearms Policy Coalition, Firearms Policy Foundation and three private citizens. The lawsuit was filed in Shasta County Superior Court.
“We’re suing because California DOJ’s Firearms Application Reporting System (CFARS) broke down during the deadline week for people to register their firearms in accordance with new state laws,” said SAF founder and Executive Vice President Alan M. Gottlieb. “For a whole week the system was largely inaccessible. People who wanted to comply with the law simply couldn’t and now they face becoming criminals because they couldn’t do what the law requires.”
The lawsuit notes that during the week of June 25-30, which was the statutory registration deadline, the CFARS system was inaccessible and inoperable on a variety of web browsers across the state. Many users who were able to initially log in and begin the process could not finish because the system crashed, obliterating all of their work. The CFARS system was substantially underfunded and understaffed from its inception, Gottlieb noted.
“It’s like a bad version of ‘Catch-22’,” Gottlieb observed. “The government required registration by the deadline, but the online registration failed and people couldn’t register. They’re required to obey the law, but the system broke down, making it impossible to obey the law. Now these people face the possibility of being prosecuted. We simply cannot abide that kind of incompetence.”
“Attorney General Xavier Becerra seems to care about everything but the constitution, the rule of law, and law-abiding California gun owners,” said FPC President Brandon Combs. “If Becerra spent as much time doing his job as he does talking about his pet crusades against the federal government, hundreds of thousands of Californians would not be in legal jeopardy right now.”
“Predictably the state of California wants to take guns away from the law abiding. In this instance they couldn’t even build a working system to respect gun owners’ rights,” explained CGF Chairman Gene Hoffman. SAF and its partners want the court to prevent DOJ from enforcing the law to allow individual plaintiffs and other citizens in the same situation to register their legally-possessed firearms through a “reliable and functional registration system.”
The Second Amendment Foundation (www.saf.org) is the nation’s oldest and largest tax-exempt education, research, publishing and legal action group focusing on the Constitutional right and heritage to privately own and possess firearms. Founded in 1974, The Foundation has grown to more than 650,000 members and supporters and conducts many programs designed to better inform the public about the consequences of gun control.
The new .224 Valkyrie for AR15-platform rifles has garnered lots of attention lately. That new cartridge has gotten people thinking about the options for an AR shooter beyond the venerable .223 Remington (and 5.56x39mm NATO). While the .224 Valkyrie is good for shooting long heavy bullets (such as Sierra’s new 95gr SMK), there is a simpler, cheaper option for folks who favor “fast and light” — smaller, lower-mass bullets traveling at very high velocities. That option is the 20 Practical, which is simply a .223 Remington necked down to 20 caliber. This little cartridge can launch 40-grainers at over 3900 fps. That’s bookin’. This makes the 20 Practical a great choice for an AR-based varmint rifle.
20 Practical Ultimate Varminter
A decade ago, as a “proof-of-concept”, AccurateShooter.com created a 20 Practical AR15 Ultimate Varminter with a custom 20-caliber upper from Robert Whitley of AR-X Enterprises, LLC. That project rifle was ultra-accurate — every 5-shot group out of the gun was less than the size of a dime. That gun was auctioned off, but Robert Whitley continues to produce custom 20 Practical AR15 uppers. (The 20 Practical cartridge is simply the .223 Rem necked down to 20 caliber — you can use standard .223 brass and load with standard.223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.)
Robert reports that the accuracy of the first 20 Practical AR15 was no fluke. After building six (6) more 20 Practical uppers, he tested them for accuracy and they all shot great. These uppers feature DPMS low-pro receivers with side charging handles. They are fitted with PacNor 1:11″ twist, three-groove stainless barrels.
Robert reports: “We have been making more 20 Practical AR15 uppers and I have to say I am astounded by the accuracy of these things. For shooting little tiny groups out of an AR15 with bullets going 3500+ fps, it’s hard to beat the 20 Practical. Today I test-fired six more uppers, all with 11-twist barrels. Three of the uppers had 24″ barrels, two had 20″ barrels, and one had an 18″ barrel (we call it ‘Stubby’).
In four of these uppers I shot re-sized Winchester brass using 25.3 grains of WC844 powder with Berger 40gr BTHP bullets loaded at 2.225″ OAL (about .015″ off the lands). WC844 is inexpensive military surplus powder that is nearly identical to H335. I tried three different primers and the choice did not seem to matter (CCI BR4, Rem 7 1/2s and Win Small Rifle — the old silver ones). All these four uppers shot great. Here is an animated GIF with targets from uppers #6, 10, and 11. All groups are mag-fed, 5-shot groups shot at 100 yards using a front rest and rear bag.”

AR-platform rifles are fun and versatile, but the standard, mil-spec triggers leave much to be desired. They tend to be gritty, with creep and heavy pull weight. One of the easiest, most effective AR upgrades is a trigger group swap. An improved fire control group makes a huge difference. There are many aftermarket trigger options for the AR platform rifles. Choose single-stage or two-stage, either standard trigger assembly or unitized “drop-in” trigger, such as those made by Timney or Triggertech.
When upgraded with a precision trigger and match barrel, AR-platform rigs work great in NRA High Power competitions (Photo from NRA Blog, at Camp Perry).
Two-Stage vs. Single-Stage Triggers
Two-stage triggers have two separate movements. The first stage offers a light, spring-loaded pressure that works against the shooter’s pull until stopping at the second stage – this is called “take-up”. If there is no spring pressure, it is known as “slack”. Should the shooter continue to pull the trigger once he’s arrived at the second stage, the mechanism will operate like a single-stage trigger from there until engaging the sear and firing the gun. Good trigger reset requires the shooter to keep pressure on the trigger, even during reset, to minimize movement of the muzzle.
Single-stage triggers feature no take-up or slack, as they begin engaging the sear as soon as the shooter begins pulling the trigger. Some competitive shooters prefer the two-stage trigger because of the feedback it provides during its first stage, while other shooters, including those using their rifle in tactical scenarios, may want the surety of a single-stage trigger, ready to engage and fire once their finger is inside the trigger guard. Regardless of preference, a good trigger will feature minimal creep and should be free of grittiness, providing a smooth, even break.
Drop-In Trigger Assembly vs. Standard Trigger Group
Once you decide between a single-stage or two-stage trigger, you can choose between standard and drop-in trigger groups. Standard trigger groups feature all the fire control group parts separated, and need to be pieced together and installed much like a mil-spec trigger, while drop-in trigger are pre-assembled and contained within a casing that simply drops in to the receiver and accepts the pins, hence the name.
After-Market Trigger Comparison
Some shooters prefer drop-in triggers due to the ease of installation, while others opt for standard groups so they can access the components individually for cleaning adjustment or replacement. If one piece of a drop-in trigger fails, you’ll need to either replace the entire unit or send it to the manufacturer for repair, whereas you may be able to simply replace the broken component of a standard trigger without needing a whole new trigger set.
Trigger Terminology — “Creep”, “Stacking”, “Overtravel”
“Creep” or “travel” is the distance the trigger moves between the end of take-up and when the trigger breaks to fire the fun. Too much creep can affect accuracy, but no creep can be unsafe, as the shooter may not be prepared to fire. “Stacking” occurs when the trigger weight actually increases during travel — this shouldn’t happen. Lastly, “overtravel” is the distance the trigger continues moving back after the gun fires.
This article is based on a longer story in the NRA Blog.
This shocking photo of destroyed AR-15 bits and pieces was posted on Facebook by William Walter, a firearms instructor. William said this was “The worst AR-15 blow-up I have ever seen. The case head literally atomized …you can see the brass residue on the parts. The bolt was split in two also.”
There’s nothing inherently wrong with AR-platform rifles (well, except that they run dirty). Over the past six decades Eugene Stoner’s semi-automatic design has proven its merits in military and civilian applications. You may not know, but the original AR from 1955 was a .30-caliber. The Armalite AR-10 shot the 7.62×51 cartridge. Later, at the request of the U.S. Military, Armalite created a smaller version that became the M16/AR15. The rest was history. Now there are millions of AR “black rifles” in the hands of soldiers and sportsmen.
With so many ARs in circulation, it’s no surprise that some get used by folks who don’t know how to hand-load or otherwise fail to follow safe gun practices. The AR is actually a pretty sturdy rifle, but when it’s fed bad ammo, or abused, bad things can happen. Very bad things… commonly known as Kabooms.
The American Shooting Journal (ASJ) has compiled a set of particularly extreme AR Kabooms. Compiling the “evidence” from various web sites, ASJ has published nine (9) of the most Unbelievable AR-15 Fails. Here are two of the worst “AR-15 Fails”. CLICK HERE to see them all.
Nothing but busted parts after this catastrophic Kaboom…
Notice the bolt is still stuck in the barrel extension … with the rest of the gun in pieces.
Another view of this sad blow-up…
These catastrophic AR failures are eye-openers, that’s for sure. ASJ cautions: “Any weapon can fail if given the wrong ammunition, faulty reloads or a plugged barrel. Always be aware of what can happen at anytime if you fail to follow common sense and gun safety rules.”
