I don't yet own an ar or any rifle in this cartridge. I was told by my friend if I want to be able to shoot military 5.56 I need a 5.56 rifle. (this makes since as I'd only want to shoot what it is chambered for). Is it true 5.56 can shoot both and .223 can only shoot .223?

yes

Awesome thanks very much.

Now I just have to find a 5.56mm rifle I like that doesn't cost as much as an AR

Mini-14, FTW!!

ETA: Incidentally, this is the reason Minis ruled the roost back in the '80s: ARs were relatively more expensive and not as readily available as the Minis were.

IIRC Mini14's are stamped 223 but actually have a 556 chamber.

That's because all Minis have 5.56 chambers, even if they are stamped .223.

ETA: Not fast enough.

Yes, unless it's a .223 Wylde chamber designed for both.....

I'm not exactly sure if either can use 5.56, but look at Kel-Tec SU16's or Saiga rifles.

You can pick up an AR for pretty cheap still, definitely sub $800 (at least in some local shops here)

I'd go with a Mini if you can't get an AR. They're OK.

AFAIK all DPMS rifles are chambered in 5.56mm––Mine and all the other ones I have handled are marked 5.56mm.

Just remember, the 5.56/.223 only matters if it is written on the upper.
Link Posted: 7/16/2009 10:21:15 PM EDT

Oh God, here we go...


"The .223 Remington is rated for a maximum of 50,000 CUP while the 5.56mm is rated for 60,000 CUP. That extra 10,000 CUP is likely sufficient to cause a failure in a chamber that's only rated for the "sporting" .223 Remington.

The .223 Remington and the 5.56mm NATO, when checked with a chamber ream from a reliable manufacturer of each, also have discernable differences in the areas of freebore diameter, freebore length (leade) and angle of the throat."

I'm talking about .223/5.56

oh and .308/7.62x51



.308/7.62NATO it's reversed. .308 is rated for higher pressures.
Link Posted: 7/16/2009 10:29:17 PM EDT
Basically, yes.

While there are a few dimensional differences between the two rounds, the main difference is the chamber pressure... Think of 5.56 as .223 Magnum... Or .223 as 5.56 Special... Either way, 5.56 is hotter and higher in chamber pressure, even if they look almost identical.

However, many guns that are marked ".223" are actually chambered in 5.56, which makes it all the more confusing...

A good general rule of thumb is, if it's an old bolt gun that says ".223", don't dare shoot 5.56 in it.

When firearms are proofed according to CIP, a charge of 30% over max is fired and causes no discernable damage to the firearms, and they will take considerably more.

Plenty of people fire 5.56 through .223 chambered barrels, but if you don't want to do it, then don't because it will only leave more ammo for the rest of us



I don't have anything chambered in 223...I have some in 5.56mm though.

But it's not just CUP...it's the dimensions. That changes things too. And is it different firing "a charge" 30% over and firing 5,000 rounds that are overpressure over a few years of shooting?

Yeah. Shooting 5.56 out of a .223 AR will make the rifle explode, the sun collapse, peace in the middle east, and people like unsweetened ice tea.

All .40 Glocks explode.

Keeping loaded magazines ruins the springs.

Chili has beans.

No we don't know what that is, go to the emergency room.

The ammo has the same dimensions, it's the chamber that differs, but when you have some .223 reamers that are more generous than 5.56 ones, where do you draw the line?

An AR15 barrel cut with a SAAMI spec reamer is the same as a bolt guns chamber cut with the same reamer, so why would it be considered safe in an AR15 but not in a bolt gun when the bolt guns barrel diameter at the chamber is usually aroung 1.200", whereas the AR15 barrel is usually 1"" dia at the same place.





Go for it, dude.

Most current manufactured hunting/general purpose rifles in .223 are chambered in Wylde, "target rifles" excluded as they may have tighter then spec chambers (.223 match). Both my Stevens 200 .223 and my Savage 10 .223 have a Wylde chamber according to Savage.

Very few rifles have a tight .223 chamber. Most rifles will handle both 5.56 and .223. (Wylde chamber) The most common exception is match rifles. The tighter leade and throat of a match rifle makes shooting 5.56 dangerous at worst (I have yet to hear about a KB from running 5.56 in a .223) and will cause cycling problems at best if it is an AR platform.

First, I follow the general no 5.56mm in .223 rule. That being said, I seriously doubt shooting 5.56mm will do any harm in a modern rifle like a Savage 10. They use the same action for .308 after all.

Well yes, but.

My neighbor just went through a bout of O. C. D. over this same thing when the only barrel he could get at Knob Creek said .223 on it instead of 5.56, he had an M4 build sitting half done and he couldn't wait.

Once he got it finished we drug it out to the range and fed it some M193 that we've had stashed for years.

It worked great.

Link Posted: 7/17/2009 8:39:32 AM EDT
I have understood it is best not to put 5.56 in a .223 gun. I thought it was something to do with the throat of the chamber being a millimeter different.

Now I look and see several people do it and think nothing of it.

So, what about putting 5.56 ammo in a Remington 700 .223 ?

Thanks,
