Absolutely... You can definitely shoot .223 out of a 5.56 chambering. 5.56 operates under heavier pressure so .223 is safe. You should not reverse the situation. do not shoot 5.56 out of .223 chamberings. you will damage your chamber.

you can definitely shoot 5.56 out of a .223 wylde chamber. Its a slightly tighter chambering tolerance and it will increase your accuracy with both calibers.

You can shoot 5.56 or .223 no problem. 5.56 is a little hotter round than .223 and this is partly why you shouldn't shoot 5.56 in a .223 barrel. The 5.56 barrels are usually heavier duty for the higher charges. The brass casing walls of 5.56 are also a little thicker than that of .223 meaning that the bore in your rifle will have no problem chambering either cartridge. If one were attempting to shoot 5.56 out of a .223 barrel, the casing diameter and high charge would be an issue.

yes.

On 5.56 you can use either 5.56 or .223
On 2.23 you can only use .223

I do not think I want to shoot a "2.23" inch barreled rifle.

I have done it for hundreds of rounds... No prob.

My friend's dad say they used to shoot .223 all the time when they ran out of 5.56 in the Air Force too.

Wouldn't that be called a cannon? Lol, that would be awesome to fire.

I know what a .223 wylde is. I just want to point out that people need to choose the right words when saying things like never fire a 5.56 out of a .223. They need to be sure to say 5.56 NATO out of a .223 Remington. Especially, when they are relaying information to others.

Edit: Also, the current mini 14 while designed for. 223 Rem also says it is fine to fire 5.56 NATO. The older mini 14 barrels are not designed for this and would be trouble if you did.

The Mini-14 manual dated 01-10-1977 for the Series 181, second series, states under AMMUNITION on page 1,

"The Mini-14 Rifle is designed to use either U.S. Military or commercial sporting .223 (5.56mm) caliber ammunition manufactured in accordance with U.S. industry practice."

The difference between the two exists largely on the internet. Before the ether it was called the "hot stove league". You know, the guys that had nothing better to do than hang around a gun shop with their feet up on the cracker barrel and spew all kinds of factoids to anyone they could corner and not let out the door.

Read it all the way through. At the end they even dispute themselves. There is nothing new in that article that hasn't been known by savvy reloaders for 40+ years. ALL GI rifle brass is thicker. Of course you reduce the loads in that brass, always have.

The .223 and the 5.56 have the same min and max headspace dimensions. The 5.56 chamber has a longer throat, but that doesn’t mean the loaded cartridge has a longer throat datum. The longer throat is for dirt, crud, and lighter, longer tracer bullets. The pressure differences are negligible. Show me a drawing that shows the throat datum of a loaded 5.56 nato round that will jamb the bullet ogive into the lands of a .223 commercial (SAAMI) chamber.
If this were true there would be hundreds if not thousands of damaged or catastrophically destroyed rifles out there. Seen very many that can be attributed to this?

Nice computer model.
Show me the throat datum on the loaded 5.56 cartridge.
Where are all the damaged chambers?

I've seen problems several times on the Range now from firing 5.56 Nato in a .223 Remington. It's always a bolt gun and so far it's only required a hammer blow to open the bolt; however, the fact that a hammer is needed tells me they were close to bad things happening...you have been warned!
