@@KentuckyLasslo If 5.56 had the capability to blow up 223 chambered rifles, we'd hear about it happening all the time but we don't, because it doesn't happen.
I've only heard about it once, but currently it's fairly rare to even have a gun in production that is .223 only, most guns are 5.56 or .223 Wylde chamber
If it does it's because it's a squib. I just made a comment explaining about a dozen different reasons why he is wrong. This is absolute textbook fuddlore.
I run 556 in a 223 breakbarrel single shot. The worst thing that’s happened was a case got stuck. Literally dropped a 6 inch piece of cleaning rod down the barrel and they both popped out easy. It’s still very accurate and the coyotes die.
Check your barrels people. And your ammo. Once made the mistake of firing a 20mm anti-materiel round out of my son's Nerf blaster. What a wacky day at the range that was! 😆
Check your barrels people. And your ammo. Once made the mistake of firing a 105mm howitzer shell out of my Daisy Red Ryder BB gun. What a wacky day at the range that was! 😆

Even before that. This might hold more true with semi autos, I use them interchangeably in my bolt and falling block guns. I'm reloading and handloading though so on paper I should be producing 58,000 psi. Im seating the bullet as close to the rifling as possible.
Did you know there isn't a recorded case of a 223 barrel blowing up from a 556 and I make 77 grain projectile with a 23 grain powder load that are about .020 from the lands and run just like any other
@@craigalston2208 223 cases and 556 cases can take the same loads and the 223 barrels run 556 just fine that barrel has to be very very very thin to cause problems
@@fishlife1013 you MIGHT get away with trying that combination out once . But let's say the summer of 2020 type riots took place again only in YOUR neighborhood are you going to bet YOUR FAMILY'S LIFE on shooting 556 bullets from a 223 gun NON-STOP ? If so then you're a fool . I WOULD RECOMMEND GET A GOOD SUPPLY OF THE CORRECT AMMUNITION FOR EACH OF YOUR GUNS & DON'T GAMBLE WITH YOUR FAMILY'S LIFE ! You never know when intruders might try to take over so be prepared with the RIGHT equipment to protect YOUR FAMILY !
Honestly, I’m glad nothing catastrophic has happened to injure you or destroy the rifle! Is it a bolt-action or semi-auto? (That does make a slight difference that I did not mention in the vid). There is still much debate out there about firing 5.56 out of a .223 barrel, but the scary truth is that there IS a larger pressure spike than recommended by gun manufacturers when firing 5.56 out of a .223, and I personally wouldn’t want an over pressured metal tube possibly detonating that close to my face! But that’s just my opinion. Another problem from shooting 5.56 in a .223 gun is throat erosion, as the 5.56 round is designed for a longer lead. It can start to wear down the early rifling in a .223 barrel, reducing its accuracy when shooting .223 as opposed to 5.56. So you'll be adding wear and tear to your barrel by doing it. In gas-operated guns, it also has a different pressure curve which can increase the pressure on the gun's piston or operating rod. The primary problem you will encounter is that a steady diet of 5.56 will damage your accuracy when shooting .223. Just some food for thought! Stay safe out there, and thanks for the comment!
Nobody seems to be talking any about the barrels rifling 223 has a 1 and 10 twist barrels most common but a 556 was designed to use heavier bullets so it has twists of one and eight or even one and seven you can shoot lightweight bullets in a tight twist gun but you can't shoot heavyweight bullets in a light twist gun so anybody is going to use 556 in a 223 is going to realize real quick that they don't shoot worth a damn 😜
@@warrenlilly2091 That is total BS. There are .223 rifles on the market from 1-7 to 1-12 twist and it actually doesn`t make a big difference what barrel twist you have. It is a lot more important if your rifle “likes” the particular cartrige. I did many tests myself and there are a load of youtube videos that show you that 78 grain in a 1/12 twist rifle works fine, same the other way around as long as your rifle/barrel "likes" that particular ammo. One can easily shoot 44 grain out if a 1/7 twist barrel if your barrel “likes” the ammo. Barrel twist rate is a general indicator but does not means crap in the real world.
Absolutely right. Here in Europe .223 chambers are anyways designed to withstand 30% overpressure to get CIP certification, so shooting 5.56 in a .223 chamber is usually perfectly fine. Best is to buy a rifle with a .223 Wylde or 5.56x45 chamber because they are designed for both types of ammo.
@@warrenlilly2091 the m16a1 had a 1in12 twist rate. You can buy .223 barrels with whatever twist you want. Mine has a 1in8 twist. My brother has one with a 1in7 twist.
The 5.56 is made for military and pressure is measured at the chamber. A 223s pressure is measured at the muzzle. They are almost exactly the same. Primers are pressed into the 5.56 so they can be used in full auto without backing out :)
@@BigShooterUnaimed then how did all the hotloads work before the 90s? Was every competition shooter just running the risk and every one of them got lucky lol?

@@chadklaren9537 308 has slightly higher pressures 7.62x51 has a slightly longer chamber and the two have different brass thickness for the most part none of that matter in modern rifles however some of the older 7.62x51 should only use 7.62 so you don’t cause a burr in the throat of the rifle and cause excessive bullet jumping that may lead to a catastrophic failure or squib load
@@chadklaren9537 ooof… wrong my friend. the .308, like the 5.56 is slightly hotter and The 7.62×51 NATO chamber is imperceptibly longer than the . 308 Winchester, extending between 0.006 and 0.010 inches beyond the . 308 SAAMI specs. This results in a 7.62 case that is ever so slightly longer than its commercial brother.
This is so false on so many levels. First of all barrels and chambers are proofed to way higher pressures than they will ever likely experience. 5000psi over pressure is not going to harm a rifle action. The freebore (section of barrel before the rifling begins) is longer in a 5.56 to improve combat reliability. It allows slightly more room for dirt, carbon, etc to be in the chamber and still cycle reliably. Pressure differences on paper also come from the two different testing methods used to measure chamber pressure for 5.56 and 223. When measured the same way the pressure differences all but disappear. 223 chambers are typically used in bolt action rifles which are by nature inherently stronger mechanically than semi autos so if a 5.56 doesn't blow up a semi auto platform it's certainly not going to damage a bolt action. That 55k psi rating on the 223 was for a standard 55gr bullet. Heavier bullets used often for hunting see much higher pressures even exceeding that of the 5.56 standard pressure. So there I just deconstructed your argument like 8 different ways. Please go read some reloading books before giving information on stuff like this. I hear this all the time from idiots at the gun counter and it's getting really old.
Exactly, I've been reloading for 20 years and firing these rounds interchangeably for 30 years, before the internet this wasn't even a question, we used them both in either chamber.
I’d take that argument with a grain of salt, as the method of testing the pressure’s on both the calibers is done to different standards and taken through different methods.
The real difference is the chamber tolerance. 5.56 is designed to fire different types of ammo (green tip, tracer, ect.) A .223 has the tolerance to fire a standard .223 round. There is no difference in pressure.
@ReapingDth tell me you onow nothing about the ammo without telling. This is not a case like the 357 being able to shoot 357 and 38 while a 38 can't shoot 357. All .223 and All 5.56 are the same no difference. If your gun is 223 its a 5.56 if it's 5.56 it is a 223. All boxes of ammo say .223/5.56 for a reason it's the same round. You are thinking of 300 blk out as it will chamber into 5.56/.223 guns but will severely damage the gun l. All boxes
I CALL BS as a shooter, reloader, and gunsmith! Where are all the BODIES? or fingers, eye balls, or missing faces? Everyone knows a cousin of a brother's sister and her boyfriend Bubba!
Kind of a myth, most modern new production rifles can safely fire both the 5.56 may wear parts slightly faster than the 223 it's only some older guns in 223 that have issues
The thing that most (experienced) shooters don't realize this with the huge upswing in new firearm owners, more and more people are buying older AR.223 rifles at pawn shops and off auction sites and bolt action .223 rifles which most certainly will wear out much faster if running the much hotter, 5.56 mm NATO. Quite possibly leading to a catastrophic failure. If you don't know for sure go by the old adage "If it isn't stamped on the barrel don't put it in there!"
Well Kentucky you forgot to tell everyone to build their AR-15 in.223 Wylde and you won't have to worry which is which that's what mine is chambered in and a 1/8 twist
Yes, could happen, but really doesn't, most are platform rifles are compatible with both. Now 300 blackout.. that's the one you wanna watch out for.... It won't with all, but it CAN chamber into some .223... That one WILL go bang, pretty much Guaranteed. Keep your ammo separate, if you have a full case of .225 or .556 make sure no .300 wind up in there. Won't even notice while speed loading
I have fallen in love with the 223 wylde chamber as of late. Always just got 5.56 barrels, but I got a Faxon match fluted barrel with a 223 wylde chamber and 1/8 5R rifling and it is insane how well it shoots. Haven't had any problems with heat either. I fired a 5 shot group of 68 grain BTHP then dumped 3 mags on M193 as fast as I could and then fired another 5 round group. The first was .75 and the second group was .82, so still sub MOA with factory loaded ammo.
Pressure is about the same as they are measured different. The "hotter" comes from 5.56 having the longer lead. 5.56 is into the lands in a .223 chamber. A lot of budget barrels in .223 have sloppy enough throat to withstand 5.56.
there are plenty of videos showing that most 223 and 556 pressures are mostly the same and some brands of 223 are higher than 556. So unless it's some old surplus ammo it's mostly the same.
I do not understand English well. Please clarify. Does this mean that a 556 weapon can be used with 223 rounds, but as for a 223 weapon, is it unsafe to put 556 rounds in it?
That is what’s documented in the manuals for designated .223 rifles. However, as many will state in the comments, they have been firing 5.56 without many problems.. There is a ‘Wylde’ barrel that can fire both 5.56 and .223 safely AND accurately.
5.56 is 60K/PSI measured via piezo transducer while the .223 is 55K/CUP measured via the copper crusher. When the known variance between the two methods are applied, they are of like pressures. While not equal, they reside within the known margin of error for the standard of either. The “leade” length in the chambers is the critical difference. Because of magazine length design restraints, OAL cartridge length must conform for proper and reliable feeding, thus establishing a narrow margin for leade specifications, which results in different go/no go OAL chamber lengths.
No, 5.56 is 62,350psi and 223 Remington (SAAMI) is either 55,000psi or 52,000 CUP. Non North American 223 Remington is the same pressure standard as 5.56 NATO.
The 5.56 is a smidge bigger and the problem he's talking about in the video could theoretically happen. I've never heard of it actually happen, though. Still, I'm chicken so I never fire 5.56 out of a .223.
Yes and no saami spec they are the same but some barrels from what I understand is 556 can sit right up on the lands of a 223 barrel which isn't much of a problem
@@LanternOfLiberty it depends on the particular 5.56 loading. The extra free float length in the 5.56 chamber enables manufacturers to load projectiles with longer profiles into them. The actual chamber pressure is the same between the .223 and 5.56, they're just measured differently.
It is. 62gr m855 just is loaded to a slighty longer overall length due to the bullet being very long from the low density of the steel penetrator tip. But just shoot them interchangeably. It is totally fine. Actually reloading manuals consider them the same lol
@@LanternOfLiberty but there are some hunting loads wich are stronger. The maximum reccomendet load for reloading is higher too. It cannot happen unless your rifle is faulty in some way and in that case it can happen with a "normal" .223 too. The only real danger is that your .223 rifle could have a tollerance wich is to small to allow a 5.56 round to go into your chamber or it will go into it and damage it, but that mostly only happens it some high end very expensive rifles. I mean you can just try it and put a round in manually and if it fits easily you can fire it without any fear of something happening. I life in Germany so i had to do a expertise on weapons to own weapons and to reload and buy the propelant i had to make a course on it too and we talked about that and that is what they where saying and i know allot of people who use 5.56 in their .223 rifles (including me) and/or load very hot .223 rounds on the maximum and yeah it works perfectly fine and i did not know anyone who had a problem and i did not know anyone who knows anyone who had a problem. The only incident i know about a rifle blowing up was of a guy reloading and he accidentaly was loading a round twice so it was his fault. Luckily he was nearly unharmed after that.
It’s just not very difficult to get the right info, this video is for the most part correct, but not about guns blowing up. He’s right that .223 isn’t supposed to be firing a 5.56, but it’s not that deadly.
@@Bandit4557 how is it right? It's like saying a 2 liter engine can't replace a 4 cylinder engine .223 can come hot or cold, 5.56 Is just the nickname for NATO mil rounds
Which is funny, because they dont even understand what the point is. Theres just "everything works" and "literally blows in your face" to them. Some people just arent smart enough to handle guns.
@@termitreter6545Some people know from years of actual experience that it doesn't matter. Then there are those who see a video and think they know better.🤡
The difference is that the 5.56 has to work in multiple military platforms reliably. It also has to have tight tolorences to work the actions of the rifles and belt fed machineguns reliably, as well as have the same pressures whether it be a tracer, ap, or ball ammo being pushed down range. .223 caliber rifles can have a variety of weights and speeds, but they do not have to work in full-auto rifles, nor belt fed anything. The only standard is what that case can handle safely, along with the caliber of metal being shot out.
556 has a looser tolerance tolerance than 223 its just a different saami spec all together. Your that both have many projectiles of different weights and shapes thats the biggest factor in knowing how safe it is as well as what chamber pressure your rifle can handle more pressure is bad but its worse if your bullet is already in the lands and grooves there is no surefire answer but following the spec but that doesn't mean your rifle can't or even shouldn't shoot 556 just cause thats what they stamped on it do your homework map your chamber know your load and the lines for your rifle might fall between what Saami says
Here’s an interesting sidebar. Back in late 1990’s I purchased two cases of Remington 62 grain match .223 ammo after shooting a 20 round box of it inside a half MOA at 100 yards in slow fire single round feed prone sling supported position with irons from my match conditioned Service Rifle. During 200 yard rapid fire stage sitting position at first match with this ammo however the rounds failed to feed from Mag to chamber. It appeared the very broad hollow point bullet tip was bumping the mag and thus stove piping the action. A call to the designer of this round at Remington revealed that this loading was never tested by Remington in an AR-15. Long story short, they refunded my money and I moved onto other brands of match .223 ammo for competition, eventually settling on 75 grain Black Hills.
A .223 Wylde chamber is a hybrid rifle chamber designed to allow .22 caliber barrels to safely fire both .223 Remington and 5.56×45mm NATO ammunition. While the cartridge dimensions of both rounds are the same, 5.56 NATO loads produce pressures in excess of the .223 safe spec.
I once fired a factory 5.56X45 in ky .223Rem chambered TC Contender. It locked the pistol up solid, had to disassemble it to remove the case. I learned my lesson.
An Omission, I’m sure, to keep a minute video from being a minute and a half. After all, How do you explain a .223 Wylde? Who’s on first, What’s on second, I don’t know is on third.
The truth of the Gospel! Jesus Christ loves you and died, rose from the dead, and ascended to heaven to pay for your sin! Repent and turn to Him and you will walk in light and be saved. Read the book of John and Luke to see God's love for you!
It’s 2022. Our metallurgy and machining processes are well refined enough to shoot 5.56 out of .223 chambers. Idk why you would, but you absolutely can.
That is right and reloading data can show powered charges that exceed any and all 5.56x45 or 223 and never does these reloading dates cause blown guns / my own reloads have so much pressures when loading 223 or 5.56x45 brass the primers are flat and at times the primer indent from firing is burnt out, never have I blown a rifle in 223 or 5.56x45 chambers / It is all a F ing lie by stupid morons that repeat heard garbage./ and also barrels aren't made from different steel for one or the other cartridges
The pressure differences just isnt enough to cause a catastrophic failure, the probability of a 5.56 exploding a .223 barrel is slim to none unless the barrel was poorly made in the first place in which case even some hotter .223 would be dangerous as well
And Ruger target chamber 223. I have a Ruger RPR in .223 that will eat long heavy high BC projectiles. My typical OAL for 75 grn BTHP (OTM) projectiles is 2.300”. Horn 10th addition lists OAL at 2.250”. Not all weapons are the same… I’ve shot a bunch of 5.56 out of .223 and never had an issue. The data above is provided under .223 service rifle data & under 5.56 NATO sections - Horn 10th edition
Also remember that a rifle chambered in .308 win can fire 7.62x51mm but a rifle chambered in 7.62 NATO can't fire a .308 WIN .it is the opposite with the .223-5.56 NATO
.125"?! That's 1/8". My friend, it's .030. Thirty THOUSANDTHS of an inch deeper till you hit the rifling between SAAMI'S blueprints of each chamber. That's it. Thats the only differences between chamberings. And it was to be able to shoot those chunky boy tracer rounds, if need be. The difference is a rounding error.
Ive pulled bullets on .223 saami ammo and found 24-24.5 grains of powder. Pull a true 5.56mm cartridge and there will be 27.5 grains of powder. OAL is the same at 2.26in and the difference in the 223 vs 556 chamber. ETA the powder charges change with projectile weight. Heavier bullets take a lighter powder charge.
M193 ammo wont cause an issue in a .223. M197 I may not continuously rapid fire it, but a shot at a time isn’t going to hurt a quality rifle. They’re proofed at 68750psi(if I remember correctly) 125% of the cartridge designated. The M855 has a heavier bullet which will cause even higher pressure. Probably would stay away from it. Doubt it blows it up, but could damage it, possibly.
It's a good idea to just check the manual for your specific firearm. My ruger mini14 is stamped for .223 but the manual says it's compatible for any 5.56 as well. 🤷♂️
I've been listening to this discussion going on 50 years now. I've shot both cartridges...out of both rifles...probable well over 200,000 rounds. Never...not once...have I had a problem. Not saying it's impossible...but problems seem to be very rare. I don't worry about it. I use Wylde barrels now. Probably more worried about the effects of peeing in the shower.
If you only know AR’s, and only compare modern store ammo, you only know that both work in your AR. I assure you, there is a difference in the cases, especially neck length. I have eight different .223 reamers. How much leade does your ammo require? Don’t know what I’m talking about? Then don’t comment.
**One of the main differences that most guys making videos like this supposedly explaining the difference between a 223 and a 556 almost always failed to mention is that the 556 is charged with much more powder for more long distance shooting making it more explosive and hotter for that matter than the 223🫡🫡
Finally someone gets it right. I'm so tired of fools who think the cartridge cases themselves have different dimension. I assume you meant room for the case to expand not the bullet, as the bullet is squeezed into the rifling. On the chamber pressure issue while it's not recommended to fire 5.56 in a .223 chamber the chances of a catastrophic failure are pretty low. The most I've ever heard of is a stuck case. .308 Winchester 7.62 NATO is the exact opposite as .308 is hotter than the NATO loading. I think that's what confuses people.
Why is that every other Gun on the planet can handle different loads and different grains, hotter round except the most common one of all? To each their own, never personally experienced seen it or heard it. Just from guys the only guns they have are AR’s.
Pretty sure that's backwards. .308 & 7.62 are a similar story but 308 is slightly hotter. My understanding is the brass is thicker on a 7.62 so the cartridge does not bend easily under war/military usage. Thicker cartridge has a little less powder. Or I'm totally wrong.
Basically 5.56 is super spicy .223 rem and should be treated as such, .223 is “technically” for civilian use and 5.56 is for shooting at baddies with armor
the SAAMI specs on the .223 and the 5.56 are only ~3,000 psi different. All rifles are proof tested at 1.5 to 2 times the nominal chamber pressure they are rated for. Therefore the 3,000 psi is well within the difference of the 5.56 to the. 223. The 308 has a nominal pressure of 63,000 psi, so that level of pressure in not outrageous at all.
the mini 14 can fire 5.56x45mm ammuntion. Although older minis are marked . 223, it says you can use 5.56mm in the manual. The mini 14 Target model is NOT rated for 5.56, it has much tighter chamber.
Any 5.56 with a capacity of more than 5 rounds is highly dangerous and should never be used. You should only use a safe single shot musket that cannot be converted to the deadly semi automatic version. Better yet, use a slingshot. I mean it took down Goliath when a fully automatic M16 was readily available with 100 round beta mags. But the slingshot was the preferred method of disposal. A shotgun fired straight up in the air is just as effective. C'mon man!
I do it all the time. My rifle never told me it wasn’t happy with the extra pressure. I shoot 5.56 through my .223 handi rifle every day. Could be rifle specific. I doubt that though. I even reload to 5.56 spec and the rifle still runs.
The weapon will fire a lesser caliber round with no problems , bit not the other way around , or else the weapon may be damaged/malfunction , or just explode due to the more powerful explosion of the round ,, A similar scenario is firing a .357 round from a .38 pistol , and being left with a busted barrel , or splitting the muzzle open like a naked umbrella ,, but the .357 will fire the .38 round for years 😅
my Savage Recon says .223 on it and its 16.5 barrel with 1:8 twist but it says .223 and .556 runs thru it smooth. i guess if you had a cheap AR but the round is the same size and the gas is mostly released aside from what moves the bolt back, exactly the same as m16 a2
First, love the comments, but no, the chamber pressure is different because of the two different ways it’s measured. The government has to do things their own way and complicate things. The 5.56 chamber is bigger for tracer rounds. Tracer rounds I would not shoot out of a .223 chamber.
Pressures are practically identical, .223 uses SAMI spec and 5.56 uses nato pressure rating systems, same rounds with the same loads, just different metrics used
Actions are tested to way way over normal chamber pressure. The little difference between .223 in & 5.56mm To be considered dangerous would mean that .223 was made out of pot metal? 😮
I dont plan on trying it but hearing the difference is only 55k psi to 60k psi makes me highly doubt a 5.56 woul blow up a .223 gun unless its alread been weakened and is on the verge of failure, working with safety equipment and manufacturing theres no way a .223 gun is only meant to ha d 55k psi as they would over design the weapon to handle a mich greate pressure so that it would last, be safer, and allow for a wider range of error in manufacturing.
What he said about the rounds is true. The difference is that most guns that are .223 are .223 wylde which shoots both rounds so most modern receivers are ok. It's all about the rifle. .223 Remington rifle is the only one you should be warry about.
