Once fired, there isn't the room for expansion that the cartridge is supposed to have. You are running the risk of higher pressure than even the 5.56 was designed for. Now many times reloaders seat bullets into the rifling for better accuracy in the 223, but the load is worked up appropriately for the chamber. Way different than off the shelf 5.56 ammo.
Go look at that nosler data, there is no difference in seating for that big heavy bullet in .223 or 5.56 but the weaker, less powerful, lower pressure cartridge called .223 REM can have MORE powder shoved inside, compressed load.

That alone should raise a red flag for you if you feel that the powder load needs to be carefully reduced to eliminate pressure issues.

The FUNNIER part is that I have yet to find a particular bullet meant for .223 or 5.56 fun, that has a different seting depth or COL for the cartridges. Meaning, same dimensions still apply regardless of the "throat or leade"

And for most of my time online, I have never seen an issue with using that COL interchangeably for .223 and 5.56x45 UNLESS the .223 Remington uses the slow twist barrel and "55 grain or less throat"

Not sure why Nosler would do that but take a look at the Accurate Powder load guide. Quite a difference.

youll notice that for similar bullet weights, the COL is identical on most bullet weights.

Notice it gives a CIP pressure limit that equals ONE Nato pressure level of 62,500 PSI ironically those loads are SAFE in SAAMI 223 Remingtons...

Good read here...specifically the tables with the different cartridge in each chamber.

So EXACTLY, what is your agenda here??? Apparently you know better than all of the firearm mfg. So why don't you tell them?? Isee guys talking about loads that HAVE to be over 70kpsi that are "safe" in their guns. Shoot what you feel like shooting in "your" gun. The .223 Remington chamber has .025 freebore. The 5.56 NATO has a .0556. The .223 Wylde has a .0619. What you are missing is the pressure rise from bullet jump or lack thereof. I don't doubt that 99% of the factory guns would have no issues with 5.56 ammo. Other than trying to "teach" us we have no idea WTF we are doing, I really don't get the point of this thread in the context it was started.

you guys that drool over a .001 difference in bullet diameter for a .17 hornet... are missing a major point here.

if a gun company in America says to use SAAMI or CIP approved factory ammunition in all rifles and NOT handloads. And that CIP .223 Remington is actually above the standard SAAMI limits for .223 Remington,


NO ONE here seems to be able to comprehend that fact. So ill make it easy..

gun company says SAAMI and CIP only

SAAMI says .223 REM is NOT 5.56 x 45 NATO

CIP says .223 REM IS EXACTLY THE SAME as 5.56 NATO

Nosler publishes load data for .223 Remington and 5.56x45 using same powder brand, bullet, seating depth, and over all length. BUT uses loads for the .223 that exceed the loads that make "max allowable pressure in 5.56 data"

or ill make it slightly easier to consider.

.223 rem/5.56 case. Case variation is null and void as most companies don't seem to do more then change the head stamp die between product runs.

same 62 grain bullet, same powder. .223 Remington gets 3 grains MORE powder, but still somehow meets SAAMI limits for .223 Remington but exceeds charge data to stay in 5.56 limits..

can I have some of what they smoke?

High Pockets..........

The cartridge case and/or the bullets are not different between the two other than obvious manufacturing differences.

You're the one missing the boat totally. But carry on with your rant about what others don't know. Its entertaining.....
