Thank you so much for covering this so completely. I've watched so many on this topic over the years and this one is by far the best explanation I have seen.
Excellent explanation, thanks!!!
Great explanation, I’m sure this will help many shooters who are unfamiliar with the differences.
I have a 223 wylde barrel that was given to me, thank you for the perfect explanation of the two
Very nicely done!!! I've heard/been following along with this topic for decades, but I do believe YOU presented more things related to it in this single video, and you did so in a nicely worded/easily understood manner folks who have little to no hands-on experience can appreciate, but also for folks with reloading/ballistics experience. I for one had heard of the .223 Wilde, but never really knew what it was about (And since I don't have any platform designed this way, just didn't take the time to do my homework on).
Thank you!
Alan...great job explaining the difference! Thank you!!!
Best explanation yet. Thanks
It's about the chamber combination. Finally someone says it again.
So many only look at the rounds but not at the interaction with certain chambers. Most no longer make those tight .223 chambers, often only on request for match rifles. If it is that tight, a few rounds and the benefit is gone, high pressure spikes too.
The wylde can make save use of both cartridges, but won't reach the optimum for either. It's a compromise.
The 223 chamber uses a shorter go gauge (1.4636) than the 5.56 (1.4646)..Many barrels marked 5.56 use the 223 short chamber and throats..
The 223 Remington was created as a military cartridge, not a commercial varmint round..The original AR15 was first designed around the 222 Remington commercial varmint round for the SCHV rifle test in the 1950's..The military then decided to change the penetration test from 300 yards to 500 yards and Stoner realized the chamber pressures would be too high to accomplish this.. Stoner then had Remington lengthen the 222 case to add more powder, which became the 223..This was at first called the 222 Special and then was changed to the 223..The 5.56 chamber has a longer minimum head space (go gauge) of 1.4646 compared to the 223 Rem commercial go gauge of 1.4636.. The 5.56 throat is also longer than the 223..The 223 Wylde uses a long throat like the 5.56 but tighter..The 223 Wylde also uses the 5.56 go gauge of 1.4646..
Is “free bore” the same as the throat?
@@VincitOmniaVeritas7 Yes, it is the distance between the bullet and where the lands and grooves begin..Some barrel makers have a gradual taper to the lands and grooves while others have a more aggressive design..Some have a short free bore while others (like the 5.56) have a longer one..The longer the free bore, the more pressure and velocity can be obtained without raising chamber pressures..The 223 Wylde has a long throat but a tighter free bore compared to the 5.56 to allow higher pressure ammunition like the 5.56, but obtain a theoretically more accurate result..
@@hairydogstail thank you very much. I remember researching this .223/5.56 topic long ago and the biggest difference was the free bore.
@@VincitOmniaVeritas7 The 5.56 also has a longer minimum chamber length than the 223..When a chamber heats up, it will shrink lengthwise..This is why the 5.56 has a go gauge of 1.4646 and the 223 uses a 1.4636 go gauge..I see many 5.56 marked barrels with an out of spec chamber ( short chamber)..Many places sell 223 go gauges marked 5.56 and they are the wrong size..
Thanks Allen. Well and thoroughly explained.
Nicely done. I get this question frequently.
Very wise explanation for this subject i really enjoy listening to someone who has the knowledge and experience to make these explanations and differences easy to understand not to mention lest we forget Kentucky Ballistics has fired hundreds of thousands of rounds and been trained extensively as a cop and still had his 50 bmg blow up in his face thank you sir for this video 👍🏻👍🏻💯🇺🇸🪖
Excellent information and letting the people know to keep them safe. Your knowledge is greatly appreciated by all in the Ar-15 rifles for fun and safe range days. The wyld chamber is cool and I personally think its wild. 😅
Great, to the point, explanation.
You are a great presenter :)
Thank you so much for this precise informations
The 556 is adopted by NATO and is a higher pressured round then the 223 rem and it's the opposite for the 308 win/762, the 308 win is higher pressured for hunting heavy game
If you are another num nuts trying to claim 5.56x45 blows up guns with 223 chambers, then you are talking out your ass and then shows us where are the photos - videos - write ups on guns blown up by shooting 5.56x45 in 223 chambers?
Or explain why reload data for 223 & 5.56x45 are the same and top loads exceed any and all Military loaded 5.56x45 showing flat primers caused by excessive pressures and the guns don't blow up!
I was loading and shooting 223 and 5.56x45 in rifles before time of Bull Clinton was president and it was normal to by military surplus ammo in 5.56x45 to shoot in all rifles from bolt guns to auto loaders with NO one blowing up guns then comes all of this PUNK ASS BS that shooting 5.56x45 in 223 chambered guns blows them up like a bomb went off.
When the Norinco 5.56x45 ammo was sold we shot ship loads of it being so cheap and brass reloadable cases and again NO one blew up 223 chambered guns.
That Norinco 5.56x45 was $2.50 a box and it was good ammo.
Great explanation.
Thanks for sharing it!
Excellent - This is why I shop with Olde English
Nice clarification on AR ammunition, now I have to decide which moderately priced rifle gives the best bang for the buck.
Anderson and Del-ton are best bang for the buck if talking .223/5.56 chambered AR’s.
I purchased a Radical Firearms AR 15 about a year and a half ago on sale for 429 at our local Midwest gun exchange. Real basic gun, all aluminum upper and lower. Shoots both .223 and .556 so that would be your choice of which. Great gun but if your just into occasional plinking, I'd go cheaper and check out polymer framed AR models since they are considered cheaper.
@@stevennewman4778 Both of those are assembled using made in China parts.
Build your own to avoid buying made in China junk
THANKS
So, just don’t shoot 5.56 in a .223 chambered AR
You've been brainwashed by TH-cam Groupie Parrot mouth talkers BULL SHIT !
There is zero problems shooting any and all 5.56x45 in guns marker 223 .
If there was, I would know it since I have fired military marked 5,56x45 in Rem 700 rifles to AR 15 I personally did the barrels chamberings using 223 chamber reamers.
And all the other people shooting 5,56x45 in 223 so where are the reports of bad things happening? tell me where?
What also indicated this is liars bull shit is reloading data for 5.56x45 & 223 are identical and max powder charges exceed all Military loaded 5.56x45 pressures so much that a fired reloaded 5.56x45 and 223 case the primers are flat from over pressure so where is this dangerous? again tell me how this is dangerous where it's done all the time?
@@dalebenson6859 Blown primers, reliability and accuracy issues..There are many catastrophic examples of blown up AR rifles with the shooter being clueless of what happened..If they admit they used a 5.56 in a 223 chamber then the warranty is gone and void..The 5.56 uses a longer minimum chamber than the 223 because the chamber will shrink lengthwise causing reliability and pressure issues..No one was brain washed lol, use the correct ammunition for the chamber..There is a reason they create specs and tolerances and Colt has always used the 1.4646 go gauge nstead of the 223 commercial go gauge of 1.4636..The differences in the throat is where the pressure problems can occur..Weatherby used a longer throat in their 300 mag to obtain the highest velocity..Use the same ammunition in a short throat 300 WBYM and problems will occur..
@@hairydogstail I can turn your own Punk ass in also for harassment so far play
@@hairydogstail Another day passes, and you can't even come to defend yourself because you can't from all of your lying TH-cam Groupie Parrot mouth talking BS and when someone corners you on your lies you turn them into TH-cam.
If you never done that - never been there - don't own guns like you don't them don't go making lying Parrot mouth BS statements!
I built an 18 inch AR and intended it to be a more precision shooting rifle and put a 223 Wylde barrel on it, for varmints of the 4 leg or 2 leg variety. But in testing rounds, I found it does prefer slightly higher weight ammo. The 62 grain fmj it really likes. It does ok with the 55 grain but it gives tighter groups with the 62 grains. I'll have to try some other rounds if I can find some heavier loads.
Thanks, how about a similar explanation about boat tail.
❤
I feel like, in today's world, if a manufacturer cannot build a rifle that will handle the slight increase in pressure, that manufacturer is not making a quality product.
Well said
Get a Wylde barrel.
