Smyth Busters: Important Info on 5.56 vs .223 Ammunition
ฝัง
- เผยแพร่เมื่อ 28 มิ.ย. 2024
- Remember the old advertising slogan, "When E.F. Hutton talks, people listen"? In the firearm industry, when SAAMI talks, we listen. The Sporting Arms & Manufacturers' Institute sets the standards for ammunition and firearms manufactured in the United States (details at SAAMI.org). The folks at SAAMI got in touch with the Smyth Busters after we released our video "Is It Safe To Shoot 5.56 in a .223 AR-15?" The ammunition you load in any gun should match the markings on the outside of the gun. With an AR-15, use the ammunition type marked on the BARREL. AR-15 receivers are sometimes marked vaguely with something like "Cal. MULTI". If your AR-15 has a .223 Remington chamber cut tighter than SAAMI specs, you should NOT fire 5.56 NATO ammo in it.
As a military round, the 5.56x45mm NATO is designed to work in a variety of firearms, and there are multiple 5.56 loads, all of which generate HIGHER pressures than civilian .223 Remington loads. Military ammo is also pressure tested using a different method from civilian ammunition. The resulting pressure statistics are not comparable - an "apples to steak knives" sort of comparison!
Higher-pressure ammunition will wear out your firearm more rapidly because higher bolt thrust puts more strain on the gun's moving parts. SAMMI defines a pierced primer, blown primer, a torn off cartridge rim, and the like as an ammunition failure. You should stop using that ammo in that gun if any of these things happen. - กีฬา
Matching the ammo type to the markings on the barrel instead of the receiver is a good point. It sounds super obvious now but I hadn't thought it until you brought it up.
That's because SAAMI almost always informed based on chamber pressure not barrel. Kind of hard to match ammo to a 223 Wylde barrel when there is no such thing as a 223 Wylde cartridge. It's all the chambering
I was thinking the exact thing. Thanks Caleb!
@@mikeyb.3306 I would at least stop making them on factory built AR or other semi automatic variants. It's nice to have the option to install one later on down the road but not for a combat rifle.
That's y I don't have markings on the receiver.
You briefly mentioned "wear" on the weapons in general when using different ammunition types.
I'm a small arms repairer in the Army. We've been using the M855A1 for a while, and we (collectively, the repairers) have seen increased wear that we've contributed to the ammunition.
The army had to make a new standard for barrel erosion because of it. Not to mention damage to the feed ramps from the rounds not being presented at the normal angle of the M855 out of legacy magazines. We've also noticed that the bolt rings seem to wear faster now.
Ive been trying to see if there is noticeable wear being caused to M4s in other places because of the ammunition. I haven't noticed anything else, but M855A1 is a pretty spicy round, so i imagine its only a matter of time.
Apparently a lot of the additional barrel wear has been attributed to the primers, which have been replaced in new production.
@@jarink1 What is different about these primers, as opposed to the M855 or these "new production" ones?
Small Arms Solutions has an article on M855A1 EPR vs M855.
"Looking at chamber pressure, both cartridges were fired in a 14.5 inch M4A1, both projectiles are a 62 grain projectile. The M855 has an average chamber pressure of 51,522 psi, which is within the 52-55,000 psi range the M4 and all 5.56mm military rifles are designed. The M855A1 is increased vastly to 61,830. In fact, you see pressure levels as high as 62,900 psi. Please keep in mind that a proof cartridge is 70,000 psi. Clearly the rifle is being significantly driven past its design parameters. The increase in chamber pressure also increases the bolt velocity substantially driving the cyclic rate much faster, which increases parts wear and service life of both the bolt and barrel."
If only citizens could get their hands on that round. Fun to know the army can just use whatever they want (aside from HP) and it is banned for civilians. Fair fight.
@@railfanningpoints2.045Your thoughts on how about chamber throat wear? Seems with that much increased pressure it might be causing havoc on the throat then compromise accuracy!
Good luck in the Gundie awards, Caleb! Everyone who's ever given him a hard time about his hair needs to go give him a vote for Most Dapper Influencer as an act of repentence.
I wish they had a "Best Hair" category.
I will give him a whole 15 votes tomorrow lol
Is he from Mayberry? 😆 Lol or is he the Mr. Rogers of firearms 😆 Lol
This guy has, arguably, the classiest hair online. No joke.
Most guys would kill for that hair. Haters... smh😏
Caleb is a breath of fresh air. Clean cut, articulate and knowledgeable. This is one of the best videos I've seen on the subject. Just last week, shooting an older CAR-15, had fired several magazines without issue. When I got to the mag's with M-855 in them, the rifle started throwing a huge muzzle flash with twice as much recoil. Actually jammed the gun a couple times. The rifle has a .223 chamber but has had thousands of rounds of M-193 5.56 ammo thru it. It definitely didn't like the 855 stuff. Probably won't be shooting M-855 thru that rifle anymore. Listen to Caleb people.
I think that's what we're seeing industry wide in a lot of .223/.223W/5.56 chambers is a huge variances on tolerances. Many ammo manufacturers since 2017 have dialed pressures back 10% because of complaints of popped primers or ammo issues. This has is very apparent on M193 variants.
I think lucky gunner did a test with different barrels and some of the. 223rem showed lower pressure than the .556 barrels with the same rounds.
I appreciate when an organization can update past misunderstandings. This is a learning process, and info is vital to safety and longevity, both to human life and the firearm. Handloaders have all this to overcome, apply and disseminate to make a quality product that may be passed to the next generation. Case capacity affecting pressures and velocities, chamber and brass resizing dimensions vary according to application, powder and bullet lots can be inconsistent. The more we know about the effects and outcomes of variables, the better we become.
Really wished you'd mentioned ".223 Wylde" chamberings. It causes even more confusion, especially for new or prospective AR owners.
That is true. Some will mention that little tidbit to not worry about it. Wylde just makes it more accurate for 5.56.
They already did:
th-cam.com/video/Ya2JqLPyx4I/w-d-xo.html
@@Ratkill9000 You're close; it makes firing .223 more accurate than it would be compared to firing it out of a 5.56 barrel, while still allowing you to fire the higher pressure 5.56 without issues. Firing .223 out of a 5.56 barrel is fine, but will be less accurate than a .223 barrel. Firing 5.56 out of a .223 barrel can cause issues because of the higher pressure.
@@Ratkill9000 Is there any real proof that the Wylde is more accurate than .223 (not 5.56)? Guys at Camp Perry say there is no proof and it is just marketing. They say there is no solid research testing that proves this hearsay.
A few years ago, I visited the Hornady and Sierra closed testing ranges. They each use a benched actions for each the .223 and 5.56 testings and for accuracy monitorings. Their test match rounds all shot one hole groups. I asked about the Wylde and the testers both said the Wylde is a great marketing move. When you eliminate the human factor, environmental, and barrel variations, both the .223 and 5.56 are as accurate as can be.
I want you guys to know that I have never watched one of your gun-care videos that I didn't learn something important. Thank you for doing this channel!!
I know they test pressures at different points in the chamber or cartridge between .223 and 5.56, just always wondered why no one seems to have tested either cartridge using one system on both. Ya know..for "science"
Came here to comment exactly this.
@@mattschmitt9924 me too. Exactly what I was thinking.
They have. The pressures vary depending on the chambering. (See ballistictools article on this.) The presumed reason for this is the length of the leade in the chamber specification and specification for the cartridge length (and probably specified powders). However, for the specific loading the pressure testing is part of specification. So, NATO spec has a pressure test standard and SAAMI spec has a pressure test standard.
Actually the youtube channel Bolt Action Reloading did a test including measuring pressures. His findings mirror what Caleb is saying. Ironically the opposite is true for 308 and 7.62x51.
So, apples = oranges. Got it.
I knew the previous video would require a follow up. Well done sir. Timely, accurate and directing people to the proper resources.
One nuance to keep in mind is import restrictions. I've heard that Saiga rifles were imported with .223 Remington marked on the receiver while being actually chambered in 5.56x45 NATO because they would be considered a sporting guns rather than military ones. I don't believe the barrels are marked with any chambering.
I have a Ruger Mini-14 Ranch Rifle from '99 and although their are no barrel markings for the caliber, it is marked on the receiver CAL. .223 not .223 Remington. The manual states that either .223 (5.56mm) or standard US military ammo can be used. Ruger also confirmed that all Mini14's with the exception of the Mini-14 target model, have 5.56mm chambers, so either .223 sporting ammo or 5.56 NATO ammunition can be safely fired.
That is my understanding. I have an earlier model, and confirmed with Ruger that it has a 5.56 NATO chamber.
That's correct, and only recently, have they stamped their barrels for 5.56.
I have a ruger ranch rifle, should I be fine with 5.56 ammo? My barrel says 223 on it.
@@Hidalguense Yes, it's good to go! 5.56 chambers all.
Thanks for the reply, gunsmith told me it was ok but second opinion its always better
Good information. Matching ammo to barrel rather than receiver makes sense. Thanks
Great information as always. Thanks gentlemen!
Thank you for the update.
I appreciate the knowledge your helping all of us understand.
Good stuff.
Strong video.💪👍
Probably one of the most interesting videos I’ve seen in a long time. Thanks Caleb!
Good job with the up-date..Much better!
So eloquently put. Another awesome video that I'm bookmarking to send out when I get this question.
Shoot the round your barrel is made for!👍🇺🇸
Thank you for sharing your priceless knowledge sir! It’s much appreciated!
Great stuff as usual!
Thanks again gentlemen!
Thank you for the video!
Thanks for the update!!
Thanks, great info. Good to see you again Caleb!
Caleb is a rather good looking fella. Appreciate you, bud ;)
Great information! Thanks for sharing this!
Great information. Agonizing delivery.
You give great presentations.
Thanks for the info!
Very valuable information for the experienced shooter and reloaders, especially a "New Shooter" or new reloaders.
Yes valuable to experienced but for a new person he was all too encompasses. Im a gunsmith and builder with 40 years of shooting and reloading behind me, I know what he was saying however the lay person would be lost....now that's my opinion
Hi this is Caleb from Brownells, and here is a note from our lawyers....
Thanks for all the information that you/brownells give us.
Its very credible on your part to come back on this and make a deep dive, if you will, to clear up some of the misunderstandings of the previous video, kudos to you. These are tools, machines, yes they experience wear and tear, and require maintenance, just like a motor vehicle. You must “fuel” them properly, like a car, needs x-octane, or your body, or needs x protein.
Excellent follow-up.
Oohhh, I love some SmythBusters! Thanks for the extra info!
Thanks for the context on Saami! Good to know for non handloaders
Synopsis: Use the ammo for which your firearm is chambered.
Great video thank you! It answered a lot of questions I had as to why Bushmaster DCM-XR Competition Rifle sometimes blows M855 primers.
Great video very informative/educational! Thanks
Not to correct the great Caleb, but M993 is Nammo's AP8 round chambered in 7.62NATO :D M995 (AP3) is the 5.56x45mm variant :D
Thanks Gabe
Great video as always 👍👌👏
Great info...thanks much !
Thanks
Shoutout to the different pressure measurement methods!,!
Great video Caleb!
Keep up the good work!
Thanks for the caveats. Good info is always welcome
Having witnessed, first hand on a range, an AR-15 blow up on a range when 5.56mm is fired through a .223 chambered AR, there is a very important difference. This occurred almost 30 years ago, in the early 90's. I quickly correct people when they say there is no difference. Luckily the friend shooting the rifle was not injured, but the rifle was destroyed.
Colt introduced confusion to the topic 30 years ago. Sitting on my lap is an AR, and the lower markings state, " Colt SPORTER MATCH HBAR CAL. 223."
The barrel is marked, " C MP 5.56 NATO 1/7 HBAR.".
I like to consider this rifle as the first ever, 223 Wylde.
Got one just like it.👍Except mine has had NATO rounds get stuck in the chamber. Installed a Geissle SSA trigger and it's a pleasure to shoot.
Have a gunsmith determine the actual chamber if you don't have chamber gauges for 5.56 NATO, .223 Rem, and .223 Wyld.
That Lower is Mil Spec and your barrel has passed the Magnetic Particle Inspection Test and you can shoot NATO 5.56 too but I'd check the stamp on your barrel first just to make sure... Ha ha ha ha... Nothing I'd worry about... 🇺🇸 🌎
Yeah Ive got one of those,too lol. A good old classic from 1995. Pretty nice trigger on mine, from the factory
Thank you wow very well explained
Awesome channel guys
THANKS
8:05 I've actually had that happen well shooting my 1911 . I had just bought a box of 45 acp ( not + P ) and I noticed a huge kick and fire ball . Stopped and took a look then seen a primer laying there on the next round . That's when I noticed that my hand had powder on and was a little burnt from being peppered by let gunpowder. Took that box home and found sixteen rounds out of 50 where way over charged.
Good thing you investigated.
what brand?
@@TreeCamper Winchester white box . 230 grain .
@@onpsxmember yup it could have been bad .
@@Portuguese-linguica Wouldn't have guessed Winchester. I haven't had any bad boxes. Maybe they corrected the mistake. Anything made by humans is imperfect.
As consumers, we need to pick a spec and stick with it, no charging handle imprint on the forehead because 65,000 psi was "too much".
Great video, excellent info!
I received some bulk reload 5.56 NATO ammo, which may have been loaded hot. I don't have chrono data, but will relate my experiences using those rounds in three firearms. (Be sure to scroll down to the Mini 14 info.)
Rock River Arms (Advanced Tactical Hunter model) 5.56 Wylde chamber purchased in 2017: Nothing unusual to report.
Colt AR-15 HBAR (round handguard, open sights), chamber marked .223, purchased from original owner in 1995: Buffer seemed to travel to max rearward position, and could hear a ringing sound (I think from buffer spring) through hearing protection after each shot. Factory .223 rounds did not do this.
Ruger Mini-14 Ranch rifle, stainless steel, purchased new in late 1980's: Significantly more perceived recoil from these rounds than factory .223 rounds. The brass was ejected even more vigorously than normal. I stepped off the distance where the brass ended up in mowed lawn and estimate 27 yards travel! The firearm did not appear to be damaged in any way, but I never shot that ammo out of that firearm again.
Listening to this is like thinking about the wear and tear on my car.
I saw a different video discussing the differences between 5.56 and .223 and they also said the pressures of these rounds were different mainly due to the differences in the ways they measured between the NATO method and the civilian method. They did say that when they used the civilian method of pressure testing ammo on the 5.56 ammo, they got very similar pressure values. They went on to say that the pressure differences is mainly due where each method measures the pressure at with in the chamber. This is not to say that all 5.56 rounds can be fired in a .223 rifle, since some of the heavier/ longer 5.56 rounds may be too long for the .223 chamber. This later instance could cause a high pressure problem in a .223 chambered rifle.
Knowledgeable, well spoken and great hair
Oh boy. I am new to all this and I have just bought my first AR lower. I haven't seen any talks of this or even companies giving these specifics in their products. Just as I thought I knew what to look for, I now have to start at square one.
Please do a video explaing the correct conversion from military to commercial pressures
Sounds like lawyers got a hold of this one.
They took the responsible action and corrected their first video by contacting the source. Good for Brownells..
@@hairydogstail it was a joke. No need to get defensive
@@TheScott2theextreme No one got defensive...

@@TheScott2theextreme No problem!
Good job!
Great video!
GREAT VIDEO. ...
Thx again
Matching ammo to what’s printed on the barrel? What a brilliant idea!
Sometimes. I have a .357 Magnum-marked revolver that I fire a lot of .38 Specials in. It will also fire .38 Short Colt and .38 Long Colt ammo. Perfectly safe with all.
@@MrTruckerf sorry to hear that.
I'm glad you cleared this up. Cuz the last one didn't sit right with me.
Thanks this answers why my bolt isn’t rocking Back correctly on my .556 daniels. I just recently tried .223 in the Daniels and it’s a no go even though the manufacturer said .223 is ok to use. Live and learn.
If you have any doubts go with vanilla 223 commercial ammo. I have a 5.56 chamber gauge and throat reamer. My SP-1 1974 production passed. The AR-180 had one tiny burr in the throat. Two brand new 5.56 DPMS barrels both had serious throat burrs that took a few turns of the reamer to get a go with the gauge. I have fired 5.56 in the SP-1 and it is weaker than some of my varmint loads. If you are reloading, go by the most recent published reloading date for your components. Family pay for hunting trip business was ammo reloading until the Mid 70's,
Enjoyed the video very much. How do you test existing ARs barrels for correct ammunition?
Great video
Long story short, your video in reference stated you could shoot 5.56 in a 223 firearm. I was shocked, and shortly after it was posted, you took it down. This is now to walk back the statements from that video. Thank you.
Yup, good for Caleb and Brownells
: OUTSTANDING info COMMENTARY
Good on them
Mine was the 223rd Like. :) Great info, as always. Thanks!
Ugh!! Caleb, making me learn stuff again. Lol 😆
Well, That made it clear as mud. I have a Ruger American in .223 that has the ejector missing from a round that went crazy. This was the 30th round out of a lot of 250, it popped the mag out and seized the bolt. Upon getting the bolt open I found a case with the base opened up. The round chambered fine, it just blew the base of the case out. This was a .223 commercial round with a 62 grain slug.
Sounds like a bad reload or remanufactured round.
@@davidunderwood3605 Ammunition failures are a thing. The case failed. It happens.
And it's always a good idea to let the ammunition manufacturer know. Case manufacture isn't difficult, but a lot of bad product can slip by between sample inspections during drawing and heading. I learned the hard way to visually inspect the draw constantly. Every 10 minutes, as specified in the process standard, wasn't nearly enough. Those machines are fast.
Mini14 is. Marked 223 but Ruger website mentions ok for 556.
Excellent video. Have you done a similar one on 308 win vs 7.62x51. Live long and prosper.
I have heard the same for Ruger 10/22. The chamber is not design for ammo like 22 lr stinger. Do to case length. But, I understand people still fire stinger through the rifle.
ROCKET MAN!
Love ya Caleb :D
I think all the ARs in the house are "multi caliber" on the receiver
Please tell me you are aware that just means it can be used for .223, .300 AAC, .50 Beowulf, 6.5 Grendel uppers edit - and more
Thanks! Good info! Could you also talk about 308 vs 7.62x51?
308 and 7.62X51 are opposite of the 223 and 5.56 NATO. The 308 has higher pressure than the 7.62X51
You Sir, are a TRUE Professional.
Very much enjoy your posts.
All the BEST in the New Year.
...pierced primers could be out of spec firing pins or bolts, too. Lots of knobs to adjust.
Yep. First thing to check is firing pin protrusion. .036 max. If my memory serves me right. But better double check, I'm old and my memory plays games.
@@davidunderwood3605 my gauge says .028 to.036 in case anyone reads this.
Damn SAAMI must have laid down the hammer real hard during that call. Still love you guys
Twist rate and bullet weight is a more important conversation than 556 vs 223
That being said, Sammy Davis Jr. was a great performer! Moral of the story, get a 5.56 or Wylde chamber, if you want diversity, and inclusion.
Sammy Hagar? I love that guy.
I've put close to 20k rounds of all kinds in my DPMS .223. Not one problem. Have yet to change anything on it. I'll keep being diverse with it.
@@bad74maverick1 Sammi, laid the salami to @Brownells, to make them sing!
What if you want to shoot diversity and inclusion?
@@PaulVerhoeven2 Then you'll have to get permission from Jobama! They'll also need your vax papers, and make sure, you're registered Democrat!
CIP (the euro SAAMI) only have one entry for the 556, so 223 and 556 are tested to the same standard. as such, if you have a euro gun (or one tested by CIP), it doesnt matter, they are the same.
Just out of curiosity...is there a recorded incident anywhere in the world, in which there was a catastrophic failure of a firearm chambered in 223 Rem, while shooting a 5.56 NATO out of it?
No. No there is not. Damn good question.
could only happen in a limited part of the world, as most countrys have CIP and 5.56 NATO is within spec of .223 REM CIP
Thus, approved ammo in those countrys is generaly safe to use.
However, individual compaibility should always be checked. One of mine had issues wit 77gr SMK loads in .223 rem.
Vlk I don't think anyone said anything about a catastrophic failure but ruptured cases, blown primers, and throat erosion have for sure happened. Long term firings of 5.56 in a .223 chamber could weaken the .223 chamber over time. So the point is its not worth firing 5.56 in .223 chambers with the damage that it can do even if it doesn't result in catastrophic failure.
Basically a firearm that runs efficiently with say Tula .223 Remington and you switch up to M855 and it starts slinging brass harder and has an increase amount of "jostle" will result after multiple 100-1000's of rounds will see an increase in parts wear, such as the gas rings, gas port, and chamber throat. You will not necessarily see your buffer spring shorten as that is more related to the number of rounds fired, but extractor spring will see accelerated wear as it is having to work harder to extract the case.
@@Mr79dream Be careful on that CIP rating. Some of those countries aren't allowed to own military caliber firearms like the 5.56x45, so the manufacturers cut "223 CIP chamber" to 5.56 dimensions and call them 223. Pretty sure CZ does that. If you were to cast a CZ 223 chamber, it would measure out to 556 dimensions, not 223 remington SAAMI dimentions.
This is one of Caleb's best videos. I always learn something from him.
You need to run this by someone that doesn’t shoot and see if they can follow it. Because I’m barely tracking this rabble
How about an intro on proofing?
If you haven’t made a video yet on this can you make one on .223 Wylde
I bought a F1 firearms king FDR. It is supposed to be 223 Wylde. But my barrel isn't stamped. I spoke to F1 firearms and they said they skipped that step in building my firearm and I'm not sure how others could be skipped also. How would I found out before I shoot other then 223 ammo? Cause I have some 556 also on hand to shoot. I'm assuming a gun smith to measure the chamber.
Thanks William
Great Video. Greetings from Germany, a country were most people think .223 Rem and 5,56x45mm NATO are the same.
Yes AR-15s here are blowing up on a weekly basis.
for US in Germany it is the same!
For 2 to 3 reasons.
5.56 NATO is within the spec of .223 REM CIP AND because we allow only CIP approved ammo to be sold!
Thus, the ammo that we can buy here is ALWAYS CIP approved, we also can't get the M855 (Green Tips)
Some of our .223 REM labled ammos, like Geco, PPU, IMI and what not, are sold in the US as 5.56 NATO, as they are outside of the SAAMI spec.
The only real NATO ammo that you can buy in Germany is rebrandet and CIP TESTED, SM ammo comes to mind here.
That said, individual firearms an ofcourse have issues with individual types of ammo.
For exsample, when my Schmeisser Ultramatch was relatively new, I could not safely fire 77gr .223rem from S&B.
Also, I had a test pack of SM rebranded Santa Barbara 5.56 NATO 55gr, which had an issue in my 16" upper, but tha issue was easily resolved by either reducing the gasport or insatlling a heavier buffer.
Yep. Even 22lr in Europe has different specs. Their chambers are tighter in older gun. That's the way it used to be but now ?.
@@davidunderwood3605 Its the same as with .223 Remington and 5,56x45mm NATO. The German .22lfb (Lang für Büchsen, eng. long for rifle) is and was not the same as .22lr (long rifle) but due to the fact, that the CIP states that they are the same, people believe this like its a divine revelation. Causing a lot of problems but not as severe due to the lack of power. Most of them are feeding and extracting issues. If you ask German people they are very likely to tell you that .22 weapons are unreliably by default, not knowing the real source of the problem. Many German sport shooters even get mad if you tell them this, because you insulted their holy CIP.
@@Grasyl I have a German made 22lr 6 gun from back in the 60's/ 70's that was sold in the U.S. .Its chambers are far tighter than U.S. chambered 22lr. It came to me second hand and one of the two cylinders ( 22lr) has marks all over it from the cases the previous owner had to pry out because a little dirty means they'll stick. I keep saying I'll ream em but then again I can buy a new American made for a few bucks more than a new reamer would cost. And yeah I lived in Germany when I was young and they get upset quick when comparing ours to theirs. But that's the nature of many things in this world. And yeah their engineering can be more precise on some things I really believe the U.S. is best in most of the firearms when we set out to produce them for precision. We have been setting bar for a century or two if we keep the bureaucratic factor out of it. But then again most countries are the same way. But again maybe not after the 30 Super Carry and .327 fed mag. Really makes me wonder. Lol.
@@davidunderwood3605 The German gun industry is a whole other story. If you are a regular gun guy in Germany and you made fist contact with the local gun industry you will have a feeling like "my hole life was a lie". That's because the German used in the gun industry is almost another language, then the one spoken at shooting ranges. I was once tasked with introducing people to this very specific langured and got so many backlashed for that.
I'm really jealous that English speakers can read stuff like Hatcher's Notebook and share this knowledge at the range. If you read a German industry book like "Rheinmetals waffentechnisches Taschenbuch" and try to talk about it at a range .. people will look at you like you have become crazy.
Excellent points. My 300 AAC Blackout receiver is marked 5.56.
