I have seen some people post 5.56 and .223 as the same ammunition. And I assuemd so. However i have heard that the NATO 5.56 is not the same and more powerful... is this true??? Whats the difference in them?? Will any 223 shoot the 5.56???
NATO ammo is loaded about 15,000PSI hotter than SAAMI, when we're talking 5.56 v. .223... you can probably get away with shooting 5.56 ammo in just about any .223, but why put all that extra stress on your chamber? it'll just burn it out that much faster, if nothing else.
with ARs, it can make an even bigger difference.. but that's a whole topic by itself.
The piezoelectric sensors or transducers NATO and SAAMI use to conduct the actual pressure measurements also differ. This difference in measurement method accounts for upwards of 137.9 MPa (20,000 psi) difference in pressure measurements. This means the NATO EPVAT maximum service pressure of 430 MPa (62,366 psi) for 5.56 mm NATO, is reduced by SAAMI to 379.21 MPa (55,000 psi) for .223 Remington.
