  1. That's incorrect. Max pressure for both are essentially the same however they measure the pressure at different locations. 556 isn't particularly spicier than 223 although a lot of commercial 223 is downloaded. The difference is the shape of the chamber where the bullet goes in. 556 basically has a little bit more room in the leade. And it is a very little bit.
