To clarify: 5.56 chamber are 2 thousands of an inch longer than 223 chamber allowing it to withstand 10,000 PSI more than the 223 chamber; so yes you can shoot 5.56 in a .223 but is not recommended since continuous shooting can weaken the chamber at the risk of a catastrophic failure. On the reverse side, 223 can be shot in a 5.56 chamber all day long. The Wilde chamber have also address the problem by allowing both cartridges to shoot thru one chamber which is neither 223 or 5.56. Agreements between NATO members regarding weapons or procedures are called a STANAG (followed by a number) or Standard Agreement or Standard NATO Agreement (take your pick) I used both in the military when stationed in Europe with the US Army Europe (USAEUR) decades ago. Back to the cartridge, I load both 5.56 and 223 casings for target shooting matches and I just loaded fast enough to get out to 600 yards with match bullets weighing between 75 to 80 grs. Short range I use military casings with 55gr or 62 grs at around 3000 to 3200 PFS out to 350 yards. I like your podcasts but sometimes are lacking on technical details.
From what I’ve seen manufacturers are using the same cases for both. Some man’s use thicker brass some use thinner but their using their same case for both. Of course the 223 is loaded a little softer. I load all mixed brass the same right until I get a little cratering.
I would be shocked if the 5.56 is not around for a longtime. The latest push to develop a newer 7mm+/- is likely another journey that goes no where. The 5.56 does a lot of stuff well and as you pointed out changing is more involved than most folks realize.
Yes, the big push is 6mm-6.8mm now. Ballistic coefficient is very high in this range. They factor in range, capacity, and weight. Personally I’m a big fan of 6.5 Grendel and that’s been out since 2004.
HA...! The Remington. 223 was introduced for the XM-16 program in the early 1960's...The 5.56 was a Belgium FN creation in the 1970's to replace the .233...thus becoming the official NATO infantryman round.
The 5.56 was the M-16 round designed to eliminate human prey. It was not a hunting round it was not a target round. It was a round fired that from a 20 inch M-16 barrel will eliminate a target at 300 meters. That is why when I entered basic training in 1978 we fired at targets 300 meters for firearms proficiency.
Yeah I've been eyeing the 6mm ARC. I think the bullet is too long, making the case shorter, to maintain that AR-15 platform compatibility. If they could basically neck up from the 5.56x45 I think it would be better. We'll see.
The Barnes 5.56 70gr TSX rounds are great. Though I didn't see anything when I was hunting a few years ago, I have no doubt those would have done the job from my 20" AR.
I use to hate 223/556 until I went to Afghanistan and witnessed the devastation it creates on impact of human tissue, with that bein said the 762×39 is in its own lane for specific duties
A rifle made in Europe generally has a barrel made to higher cip specifications therefore 556 can be fired in the rifle chambered for 223. cip is usually stamped on the rifle and barrel . Whereas a rifle barrel made in the u.s for example is made to Sammi specs so it may not be safe to fire a 556 in a 223 barrel.
So why do gun manufacturers just not chamber all new rifles to 5.56 specs and be done with it? Are there accuracy issues or something? why are civilian 223 rifles still made?
223 and 5.56 have same out side sizes ..you say that right off .so they will fit ... BOTH have the same proof pressure .. so its just the 5.56 might have a wee bit higher op pressure ..but 223 at 3240 is the same as 5.56 at 3240 .. crimped primer , sealed .. no big deal .. so if nato 556 was in the 1970's then what did they use in the 1960's ....
@@katana258 yes and that doesent have anything to do with the ammo in use proof ammo is for testing over pressure... Jesus dude are you an idiot it's not the operating pressure which a firearm especially military rifles have to use that pressure and fire usually an exorbitant amount of rounds.... Cmon man do some thinking
i think it will be replace by a heavier better bc bullets, one that will still fit in the ar platform. like 6arc and 6.5 grendel. mostly because of new computer electronic scopes, this gives unskilled soldiers the ability to shoot 1000yr shots easily. if an enemy has to travel 500m or around 3 mins or running just to close the gap just to be able to take those very skilled difficult shots back. a simple barrel and caliber change is a no brainier for the military. it can multiply the potential of a very small a force drastically.
@@briant7652 artillery and air drops can only do so much if the enemy has massive numbers and decides to zerg rush. if the enemies have 400 yrd rifles. and have to close a 600 meter gap. and the typical geared soldier can move 6.1 mph. that's over 3 and a half minuets of pure full on sprinting. in that time if a soldier can shoot 1 round per second focused single shots, thats over 200 rounds fired before the enemy can even close the distance.

The cautionary tale of .223 vs 5.56 is vastly different than gasoline vs. diesel fuel. Firing 5.56 in a .223 barrel will result in reduced barrel life more than it will result in catastrophic detonation. However, unfortunately, the old axiom of "better safe than sorry" leaves too much room for the most agregious horror stories. Just as if someone said that filling a gas tank with diesel will blow up with enough force to crack the mantel of the earth. It's BS.

Easy to carry, more to carry but if you use a small fast bullet you will wound instead of killing, that wounded soldier will take another one out of the fight
That's a pervasive myth that just won't die. 5.56 was not designed only to wound, it was designed to kill with less. Merely wounding a soldier will not take another soldier out of the fight trying to help him, because people don't just stop in the middle of a firefight to render aid.
@@justaregularguy3827 I stand corrected and since I can't think of a good reason as to why I would say 62 instead of 63, I am going to blame fat fingers on a phone keyboard.

6mm ARC is the round with the most promise right now, it shoots flatter, longer, and really bridges the gap between 5.56 and 7.62.

.223 is great. Barrel twist and barrel length do matter though
You guys should do the Soviet cartridges.

Yes, but highly highly NOT recomended!

It's the 6.5 TCU. It was made for target shooting iirc
