I did read it & that`s why I posted it, so you could make up your own mind.........But right off the bat he says.
If you’re unfamiliar with the differences between .223 and 5.56, you should understand the following basic facts:
1. The exterior (physical) dimensions of .223 and 5.56 ammunition are effectively identical.
2. 5.56 ammunition (MAY) be loaded to higher pressures than .223 ammunition.
3. 5.56mm chambers are dimensionally larger in certain critical areas than .223 chambers.
4. Given the same ammunition, 5.56 chambers will have lower pressures than .223 chambers.
