Hello Steve 4102
"There is no difference in absolute pressure between .223 Remington and 5.56 NATO. None!"
If what I'm reading is good information, then why do we need a NATO chamber ? RiverRunner brought up the M855 ammo as well. It does seem to be significantly "hotter" than standard NATO loads.

So, why do we need a NATO chamber ?
