#10MinuteTalk

Honestly, who doesn’t have a 5.56 or one of the new and fancy “.223 Wylde’s” in their arsenal? This cartridge has become one of if not the most ubiquitous cartridges in our world and we often take it for granted just being there and being what it is. Ryan Muckenhirn joins Jimmy and Mark to take it back to where it all began, what the cartridge has been intended for in its long use with NATO forces, how many different loads there are, what makes it different from its civilian cousin the .223, and what might be the future of this cartridge? Check it out!

Estimated 16 million AR-15’s in the U.S. alone, who knows how many Ruger mini-14’s or other similar rifles. This little beast is here to stay!

[@ricblic901]

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.

[@alfonsorodriguez6437]

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.

[@jefferyboring4410]

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.

[@TheIamfrustrated]

5.56 forever!

[@bandogmerch]

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.

[@justaregularguy3827]

They just supped it up hahah

[@0214Bub]

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.

[@primalj_2a433]

It's not going anywhere

[@briant7652]

CAG went to 6mm. The Army is likely going to 6.8mm. NATO countries will stick with 5.56 because they're broke.

[@Coyote-wm5op]

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.

[@Fister_of_Muppets]

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.

[@Coyote-wm5op]

This standard won’t change unless a new technology comes out that drastically changes the game.

[@csmith1]

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.

[@fishermandancrook]

.223 is great. Barrel twist and barrel length do matter though

[@acester86]

You guys should do the Soviet cartridges.

[@ryanehlis426]

The 556 and AR is the new 30-30, inside 200 yards with good hunting bullets good deer and pig killer.

[@Patriotusa44]

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.

[@JMane3000]

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

Where can I get the poster of the gal in aviators with a cap?

[@Gchang54]

5.56 in a 16+inch barrel is a proven platform

[@John-hf1ig]

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.

[@dr.froghopper6711]

6.5 Grendel is darned close!

[@mannequinfukr]

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

[@stevenmike1878]

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.

[@stevenmike1878]

@@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.

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 ....

I am one of those that dislike both the 223 and the 5.56mm. I think it would have been better as a 253 or a 6.35x45 but that is just me... in-case you didn't get it my 253 is a 25 cal in the 223 case Also please talk about the 10.3x68

[@The10thManRules]

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.

@@briant7652 design-wise AP ammo just kinda goes hand-in-hand with sniper rifles because of them generally having longer barrels to maximize velocity and minimize drop and wind drift. Speed is how you beat armor, you can have the hardest material ever but if it's traveling at 40fps it won't even break the skin, meanwhile if you could fire a grain of rice at 5000fps it would explode like a grenade upon impact.

Australia had the 7.62 in it's auto FN Rifle in Vietnam and while you can carry plenty of rounds it is too weak and too small sorry. going this way was a mistake. The new calibre and rifle for the USA clearly is a reaction to that and need to hit harder against vests.
