I have an old Ruger mini14 Ranch rifle, stamped as .223. According to Ruger it is designed to fire 556, however at the time of manufacture 556 was not allowed to be used by the public. In the case of older rifles, check with the manufacturer and provide serial numbers to be sure. I safely fire 556 with no issue.

@@redtra236 According to Ruger... Anyway this was during the Clinton Administration. He was trying to do what Biden is trying now, trying to outlaw the sale of 5.56. What Ruger did was forego any future complications in sales by simply stamping their product with .223. Whether the 5.56 round was actually outlawed or not is really not even the point of my post (I guess I could have worded it differently). The point was, that this may have occurred with other rifles, so contact the manufacturer. It is most likely to happen again.
I would add this: if you are still in doubt, or have additional questions, contact the manufacturer of the firearm. As the manufacturer of that weapon, their answer will be the most accurate and up to date.
All boxes of .223 say .223/5.56. Same with all boxes of 5.56 saying 5.56/.223 my friend 2 years ago everyone knew 5.56 and .223 are one in the same how come now you think they are not.
Thanks man. I just bought a Colt AR-15 a few days ago and the shop I bought it from sold me some 223 rounds. I went to academy today and bought some 5.56 rounds, but I was still pretty upset until I saw this video lol.
Man I had a chance to buy a colt AR about 15 years ago. I turned it down because I had a bushmaster that I was happy with. But I really wish I’d got that colt*. Congratulations and stay sharp.
Dude they are ethe same round. 5.56 is metric for .223 the boxes if you look closely both say .223/5.56 ot vise versa their is no such thing as both .223 and 5.56 it's the same fucking bullet
Brownell's "Smyth Busters" say it is okay to fire 5.56 from a .223 chambered rifle, especially modern rifles, which can typically exceed the max pressure a .556 round would produce.
If you consult a reloading manual you will find the .223 is loaded with more powder than the 5.56. This is done in cases that are exactly alike. Even if you use 80 grain bullets the .223 is still loaded with more powder which will produce more pressure. I believe this shows the semi auto action of the 5.56 is not considered to be as strong as a bolt action.
@@societyisboring the cartridge themselves are 99% identical. The cut of the chamber is where the differences lay. 5.56mm has a slightly larger throat and longer leade. .223 is slightly tighter and a much shorter leade. This slightly tighter throat can cause increased pressure spikes
The pressures of the two cartridges are measured differently (PSI vs CUP) which results in a different pressure number. They're closer than you think. 50,000 CUP is over 60,000 PSI. The real difference is some 5.56mm loads have heavier bullets that won't stabilize in standard .223 Rem barrels. My Remington 700 is far stronger than an AR. But the 700 has 1-12" twist whereas the AR can have 1-9", 1-8" or even 1-7" depending on the brand. My 700 likes bullets below 62 gr while an AR will fire 77 gr bullets. ARs have longer throats to accommodate the longer bullets.
.223 is supposedly slightly less accurate when fired from a 5.56 rifle, and generally .223 rifles it's regarded as being more accurate than 5.56 ones. A rifle with a.223 Wylde barrel/chamber is supposed to have the accuracy advantage of a .223 and remain compatible with both cartridges just like a .556 barrel/chamber.
"Wylde" exists to combat the misunderstanding about .223 ammo and 5.56x45 NATO ammo not being able to be shot in the same gun. It's literally to 'trick' consumers into not worrying about that thing they don't need to worry about.
@@D70340 Well you can shoot 40 S&W out of a 10mm autoloader, but it headspaces off the extractor. To do it in a revolver you have to have moon clips since its not rimmed but if you use moon clips its fine.
More like the difference between .38 ACP and .38 Super, where the external dimensions of the cartridge are essentially identical, but one is loaded to a significantly higher pressure than the other.
omg TY, a simple direct answer without the history of the gaw dang rifle and the round like all the other channel that tried to explain a yes or no answer.
I agree its what stamped on the barrel but i own a benelli MR1 marked .223 but i as well as the previous owner have been shooting. 556 out of it for years no less than 500 rounds, its a much heavier barrel than any of my .556's. I understand the chamber is smaller and although i have never done a velocity test i would imagine its above the 3200 f/sec marked on the ammo boxes. When i first learned all mr-1 sold in the US are .223 i had to check mine and sure enough the barrel is marked for just .223 but i already had 400+ .556 through it. Not concerned anymore i still take it out a d fire off .556 i would imagine the pressures are incredibly high but it works. Just want to add im using 55gr. that could be a reason it works too. I dont think ill try anything heavier
@@societyisboring the bullets are the same. The cartridge loadings are mostly the same. The chamber and throat of the barrel are different, with .223 being tighter.
Not educational he is lying. Like all gun dealers do 5.56 and .223 are the same exact round. It's not lile the .38 vs 357 debate. They are the same size same grain same powder ammount they are the same. 5.56 is metric for .223
Since most rifles that have .223 remington are bolt action it's a non issue. Bolt actions can handle high pressures plus they have vent holes for when a case head ruptures.
Hmmmm…….back in the early 1990’s I had a custom wildcat rifle built, chambered for a 6.5-08…… a .308 necked down to 6.5mm with a 1-8 twist rate. Now I suppose some of you fellas will tell me that the wildcat round will not interchange with a .260 Remington.
Where do you get the idea that the 5.56 can produce so much more pressure than the .223? All the information I have shows just the opposite. Since the cases are exactly the same size and if the bullets are the same then all my load data shows the .223 being charged with more powder in every case resulting is slower bullets from the 5.56. More powder in the same case will produce more pressure. I would be afraid to use my .223 loads in a black rifle. The data I have, which was produced by Sierra, shows the same reduced loads for the 5.56 all the way to an 80 grain bullet where my information stops.
5.56mm is often loaded slightly hotter than civilian .223 (think of 5.56mm as +P). However, the real difference between the two is the cut of the chamber. .223 has a slightly tighter throat and shorter leade than 5.56mm. This tighter throat can create the higher pressure spikes that everyone alludes to.
So basically for the apocalypse I should get a semi auto 5.56 that can also shoot .223 and a .357 magnum that can shoot .357 and .38 SP so I have the best of both worlds when scavenging
I like the video about the difference. Unfortunately I won’t be buying either from you guys are your prices are bonkers.. I mean 18.00 for a box of 20 223 plinking rounds is crazy…
The whole 5.56 vs .223 thing is a holdover from old commercial traditions with military and civilians arms. .223 was the commercial name and 5.56 was the military name, same cartridge just loaded differently. There's nothing notably different with the dimensions either, you'll get more variation in dimension with cartridges out of the same box of ammo as you will between 5.56 and .223 spec dimensions. When someone genuinely has a catastrophic failure with shooting a 5.56 out of a .223 marked barrel with a modern firearm then I'll care. There's .223 cartridges that have a higher pressure or just as high pressure than 5.56 everywhere. You telling me shooting 50k PSI 5.56 is bad but 50k PSI .223 is fine? No, that's not how it works. tl;dr No one has ever had a problem shooting 5.56 out if a .223 despite what these people say. Non-issue.
the difference is not in the cartridge per say (although there are some 5.56mm loads that are far hotter than civilian .223), it's the cut of the chamber. .223 has a tighter throat and shorter leade than 5.6mm.
Well he said "YES and NO" right off. Likely it's safe, but 5.56 Nato is designed for the higher pressures. Probably most .223's are within safety and design margins, but liablility-wise they don't want the attorneys chasing them down.
How in the world does a chamber affect the amount of pressure a firearm can handle? The 5.56 chamber is designed to deal with dirty ammo, don't drag your gun through the mud and happy shooting.
The chamber dimensions are critical for a gas seal, and to keep the bullet from touching(or even being forced into) the rifling. A poor gas seal will cause short cycling, where the BCG does not recoil fully, causing unreliable ejection, feed or both. Rounds with too long of a COL(cartridge overall length) can actually be forced into the rifling when the BCG slams into breech and the bolt rotates to lock up. When fired, the bullet will not have freebore to gain speed before entering the rifling, and will cause very erratic spikes in pressure, and negatively affecting accuracy.
@@boeing352 wow, I had forgotten about this one, but I believe you misunderstood my point. The video stated that the two chambers create different pressures. Assuming that either chamber is correctly cut with appropriate headspace and dimensions, it will have no effect on chamber pressure.
Incorrect. If you put a 300cuin piston in a 305cuin cylinder, what happens? Poor seal and blow by. This ruins compression, and this combustion. If you put a slightly dissimilar. 223 in a 5.56, you get enough seal and pressure, to actuate the BCG. If you put a 5.56 in the tighter chamber of a .223, you will get spiked pressures and excessive wear if not catastrophic failure.
@jic1 the cartridge has nothing to do with the statement in the video. The video states that the chamber causes different pressures, that is an incorrect statement.
If both a .223 Rem and a 5.56mm both have the same 55 grain bullet and almost identical ballistics as far as velocity, isn't the pressure then almost the same ?
they have slightly different chamber and throat profiles. .223 has a slightly tighter throat and shorter leade/freebore. That is what can potentially cause the higher pressure spikes. Also, military spec 5.56mm can be slightly hotter than civilian .223. Think of 5.56mm as .223 +P.
then why just put 5.56 NATO barrel stamp on it. If 223 Wylde how ever you spell it just annoying to mark unnecessary steps to look for that weird caliber if it can do a 5.56 NATO barrel thanks for pointing it out on that barrel
For a typical AR chamber, both are fine. But don’t try jamming a 5.55 into a 1962 bolt action .223. The reamed leade lengths are different. Your 5.56 case will jam.
WRONG !!!! 5.56N can not produce 20 0000 psi more pressure. This has been debunked time and time again. On military spec there is higher chamber pressure number becaue military measures the pressure differently. If you switch the åressure measurement mehods then .223 Rem can produce 20000 PSI more pressure than 5.56N if .223 Rem is measured with Military method and 5.56N with SAAMI method. There is minute pressure difference between caliber for 5.56N benefit, but that is negliable and difference is smaller that the pressure difference between different ammo production batches. Real difference: 5.56N is just as cheap and low quality .223 Rem. 5.56N FMJ has nothing on .223 Rem Lapua Match HPBT
@@jamesosekowsky8303 I mean it's extremely unlikely that 5.56 in a .223 is gonna make it explode. Especially a Mini-14 which I think is actually a 5.56 chamber normally even if marked .223
i guess my .30 Carbine cant shoot 7.62x33 as we are American standard, and NATO is a metric system . i have never had issues, but i do reload . look at a reloading manual @ 556 in a 223 . also maybe i shouldn't shoot 12.7×99mm NATO in my .50 BMG. or even 7.62×63mm in my 30/06.or 7.62x51 in my .308
3rd video I’ve seen that parrots the same false information. Have you ever heard of +P ammunition??? Exactly what part of your rifle will be damaged by these higher pressures? Are there any documented cases of failure or injury from shooting 556 out of a 223 rifle?
The higher pressures are in the 5.56 rifle using that ammo. You can shoot .223 ammo in a 5.56 rifle with slightly less accuracy. You cannot shoot 5.56 ammo in a rifle chambered for .223 ammo due to the increased pressure of the 5.56.
@@kayladonatucci7548 Speaking from experience since my original post: over the last 30 days, I’ve shot hundreds of rounds of 556 ammunition out of my Rock River chambered in 223. No jams, no issues. I’d encourage everyone to seek out accurate information from an expert (like a reloader or an experienced hunter) before repeating tired misinformation.
I’ve never seen +P rifle ammo, but you bring up an interesting point. I know for sure that some of the firearms I’ve purchased had it specified in the manual that they could shoot +P ammo, but I’m not sure if all of them could
They're not higher pressure anyway. Dude says 5.56 can make "20,000 PSI more than .223...". Ha-ha-ha. Have you ever shot .223 and 5.56 through the same chronograph? Did the 5.56 go 4,300 FPS at the muzzle while the .223 was going 3100 FPS? Yeah, because no it didn't. This video is full of obvious logical errors - like that one - and other straight terrible misinformation that other commenters here have pointed out.
@@dundeeecroc That not true at all, they are practically the same case dimensions just 5.56 NATO has a heated treated case, crimped primer pocket, and a very minuscule case shoulder differentiate the bullet caliber are the same 5.56x45mm is military designation for .223 Remington, and 5.56x45mm NATO cartridge more so pertains to the case enhancements slightly hotter powder load and the SS109/M855 and L110/M856 62gr bullets, both .223 Remington and 5.56x45mm NATO will fit the same chamber.
@@dundeeecroc Definitely not true at all I've seen people shoot 5.56 in .223 chambered bolt actions. Never heard of a catastrophic failure from it, but the max PSI on 5.56 is 62K and its 55K for .223. I highly doubt it would cause a catastrophic failure in most weapons but shooting a lot of slightly overpressure ammo that your rifle may not be designed to tolerate could cause damage and potentially a catastrophic failure eventually.

Well he said "YES and NO" right off. Likely it's safe, but 5.56 Nato is designed for the higher pressures. Probably most .223's are within safety and design margins, but liablility-wise they don't want the attorneys chasing them down.
how about the buffer spring for an ar?...i feel like mine is takin a beating w 5.56 compared to .223
Thx
But if as in a CZ Bren 2ms the gas knob is stamped 556 on one side and 223 on the other can you shoot both?
How in the world does a chamber affect the amount of pressure a firearm can handle? The 5.56 chamber is designed to deal with dirty ammo, don't drag your gun through the mud and happy shooting.
The chamber dimensions are critical for a gas seal, and to keep the bullet from touching(or even being forced into) the rifling. A poor gas seal will cause short cycling, where the BCG does not recoil fully, causing unreliable ejection, feed or both. Rounds with too long of a COL(cartridge overall length) can actually be forced into the rifling when the BCG slams into breech and the bolt rotates to lock up. When fired, the bullet will not have freebore to gain speed before entering the rifling, and will cause very erratic spikes in pressure, and negatively affecting accuracy.
@@boeing352 wow, I had forgotten about this one, but I believe you misunderstood my point. The video stated that the two chambers create different pressures. Assuming that either chamber is correctly cut with appropriate headspace and dimensions, it will have no effect on chamber pressure.
Incorrect. If you put a 300cuin piston in a 305cuin cylinder, what happens? Poor seal and blow by. This ruins compression, and this combustion. If you put a slightly dissimilar. 223 in a 5.56, you get enough seal and pressure, to actuate the BCG. If you put a 5.56 in the tighter chamber of a .223, you will get spiked pressures and excessive wear if not catastrophic failure.
The chamber doesn't create the extra pressure, the cartridges are specced differently.
@jic1 the cartridge has nothing to do with the statement in the video. The video states that the chamber causes different pressures, that is an incorrect statement.
Yes
Its written on the receiver?
If both a .223 Rem and a 5.56mm both have the same 55 grain bullet and almost identical ballistics as far as velocity, isn't the pressure then almost the same ?
they have slightly different chamber and throat profiles. .223 has a slightly tighter throat and shorter leade/freebore. That is what can potentially cause the higher pressure spikes. Also, military spec 5.56mm can be slightly hotter than civilian .223. Think of 5.56mm as .223 +P.
I know people talk about their 3rd cousin best friend bought a gun .
0:46 "...the 223 wild". . . WTH is a "223 wild"? What's he saying there? Anyone know?
Wylde. Its a hybrid chamber that allows you to shoot either with more accuracy than .223 in a longer 5.56 chamber
@@boeing352 That is really very interesting. Thank you.
What if the barrel is stamped 5.56 and the lower says 223 Rem?
The load bearing parts are all in the upper so its fine. It's extremely unlikely that shooting 5.56 in a .223 would cause the gun to explode though.
Simple, go 5.56 and not worry
🧠 fast, good info
Yes but not the other way around
Yes.
Go gauge for 223 is 1.4636... Go gauge for 5.56 is 1.4646...
Just buy the right ammunition for your gun how hard is that.
If I have a 5.56 that’s not NATO, can I shoot a 223 in it?
Yes. There is only one 5.56
@@boeing352 thank you. Just wanted to make certain.
223 wylde is the best of both worlds
then why just put 5.56 NATO barrel stamp on it. If 223 Wylde how ever you spell it just annoying to mark unnecessary steps to look for that weird caliber if it can do a 5.56 NATO barrel thanks for pointing it out on that barrel
Ayo holy shit I get it now
5.56mm = Military Round. .223 Remington = watered down civilian trash. For equal example, See: .357 magnum vs .38 Special.
For a typical AR chamber, both are fine. But don’t try jamming a 5.55 into a 1962 bolt action .223. The reamed leade lengths are different. Your 5.56 case will jam.
I call B.S. there is not 1 video on RUclips (or thr net) showing a .223 blowing ip from firing a 5.56 in it! -- tou EVER seen one? Hummmm
👍
20,000. Lol c, mon
WRONG !!!!
5.56N can not produce 20 0000 psi more pressure.
This has been debunked time and time again. On military spec there is higher chamber pressure number becaue military measures the pressure differently.
If you switch the åressure measurement mehods then
.223 Rem can produce 20000 PSI more pressure than 5.56N if .223 Rem is measured with Military method and 5.56N with SAAMI method.
There is minute pressure difference between caliber for 5.56N benefit, but that is negliable and difference is smaller that the pressure difference between different ammo production batches.
Real difference: 5.56N is just as cheap and low quality .223 Rem.
5.56N FMJ has nothing on .223 Rem Lapua Match HPBT
My Ruger Mini 14 is a .223 but it handles both.
are you lucky?....or what?
did u check with the manufacturer? The only reason I ask is so nothing happens to you or your gun
According to Ruger a Mini-14 will shoot either except for the target model which only shoots .223.
@@jamesosekowsky8303 I mean it's extremely unlikely that 5.56 in a .223 is gonna make it explode. Especially a Mini-14 which I think is actually a 5.56 chamber normally even if marked .223
😃👍😎
i guess my .30 Carbine cant shoot 7.62x33 as we are American standard, and NATO is a metric system . i have never had issues, but i do reload . look at a reloading manual @
556 in a 223 . also maybe i shouldn't shoot 12.7×99mm NATO in my .50 BMG. or even 7.62×63mm in my 30/06.or 7.62x51 in my .308
the issue is that 5.56mm and .223 actually have slightly different chamber dimensions. It's not just the metric to imperial conversion.
So yoh didn’t say much ok
Use your common sense, use the ammo your gun is bored for.
So glad I got a 5.56 rated AR best of both worlds 😂🤙
3rd video I’ve seen that parrots the same false information. Have you ever heard of +P ammunition??? Exactly what part of your rifle will be damaged by these higher pressures? Are there any documented cases of failure or injury from shooting 556 out of a 223 rifle?
The higher pressures are in the 5.56 rifle using that ammo. You can shoot .223 ammo in a 5.56 rifle with slightly less accuracy. You cannot shoot 5.56 ammo in a rifle chambered for .223 ammo due to the increased pressure of the 5.56.
@@kayladonatucci7548 Speaking from experience since my original post: over the last 30 days, I’ve shot hundreds of rounds of 556 ammunition out of my Rock River chambered in 223. No jams, no issues.
I’d encourage everyone to seek out accurate information from an expert (like a reloader or an experienced hunter) before repeating tired misinformation.
I’ve never seen +P rifle ammo, but you bring up an interesting point.
I know for sure that some of the firearms I’ve purchased had it specified in the manual that they could shoot +P ammo, but I’m not sure if all of them could
They're not higher pressure anyway. Dude says 5.56 can make "20,000 PSI more than .223...". Ha-ha-ha.
Have you ever shot .223 and 5.56 through the same chronograph? Did the 5.56 go 4,300 FPS at the muzzle while the .223 was going 3100 FPS? Yeah, because no it didn't.
This video is full of obvious logical errors - like that one - and other straight terrible misinformation that other commenters here have pointed out.
@@jefforymerten9613 yep
😂
Stupid responses!!!!!!!!
This is bullshit, show me the .223 gun that blew up from eating 5.56!
it would get stuck before it fires, it won't fire because the bolt won't close fully.
@@dundeeecroc That not true at all, they are practically the same case dimensions just 5.56 NATO has a heated treated case, crimped primer pocket, and a very minuscule case shoulder differentiate the bullet caliber are the same 5.56x45mm is military designation for .223 Remington, and 5.56x45mm NATO cartridge more so pertains to the case enhancements slightly hotter powder load and the SS109/M855 and L110/M856 62gr bullets, both .223 Remington and 5.56x45mm NATO will fit the same chamber.
@@dundeeecroc Definitely not true at all I've seen people shoot 5.56 in .223 chambered bolt actions. Never heard of a catastrophic failure from it, but the max PSI on 5.56 is 62K and its 55K for .223. I highly doubt it would cause a catastrophic failure in most weapons but shooting a lot of slightly overpressure ammo that your rifle may not be designed to tolerate could cause damage and potentially a catastrophic failure eventually.
@@Edmondson_Avenue Thanks for the clarification. better understanding of your explanation. Thanks
223 is 556 in metric
No. 5.56 and .223 are made to different standards.
Thank you
