Then explain to me why military brass has less case capacity and is heavier.
US military 5.56mm brass does not have less capacity and it is not heavier. I have weighed .223 and 5.56mm cases for years. The heaviest cases made are Lapua match. Some Brit 5.56mm cases are very heavy.

Go to the link: Click on Tech and then click on brass weights.

Gee, probably all the SAAMI members who must abide by the SAAMI specs for every firearm chamber they cut.
Not so. For about 25 years Ruger has said that their rifles rifles will accept either 5.56mm or .223 ammo.
