The cases tend to have similar case capacity when measured, with variations chiefly due to brand, not 5.56 vs .223 designation. The result of this is that there is no such thing as "5.56 brass" or ".223 brass", the differences in the cartridges lie in pressure ratings and in chamber leade length, not in the shape or thickness of the brass.

The major dimensional difference between the chambers that fire the .223 Remington and the 5.56×45mm NATO is the longer and larger-diameter "freebore" [3] in the 5.56 chamber (0.0566 in (1.44 mm) vs 0.0250 in (0.64 mm) length, 0.2265 in (5.75 mm) vs 0.2240 in (5.69 mm) diameter). Freebore is a short and smooth section of the barrel that is ...
The AR-15 rifle usually comes chambered for either the military cartridge 5.56×45mm or the .223 Remington. Because of the pressures associated with the 5.56×45mm, it is not advisable to fire 5.56×45mm rounds in an AR-15 marked as .223 Remington, since this can result in damage to the rifle or injury to the shooter.

The official name for .223 Remington in the US Army is cartridge 5.56x45mm ball, M193. If a 5.56×45mm NATO cartridge is loaded into a chamber intended to use .223 Remington, the bullet will be in contact with the rifling and the forcing cone is very tight. This generates a much higher pressure than .223 Remington chambers are designed for. [3]
The .22 TCM (Tuason, Craig, Micromagnum) is a proprietary bottlenecked rimless cartridge derived from a 5.56×45mm NATO (.223 Remington) parent case. It was developed by custom gunsmith Fred Craig in collaboration with Martin Tuason, the President of Rock Island Armory (RIA) and Armscor. The cartridge is primarily used in Rock Island Armory ...
Other benefits of the SAAMI conformal transducer are: very adaptive to the high volume quality control testing demands of commercial and law enforcement ammunition production; protection of the transducer from direct exposure to the high temperature combustion gases and hence a comparatively long service life; 80,000 psi (551.6 MPa) maximum ...
In January 2017 Nosler introduced the .22 Nosler. It is the fifth cartridge designed by Nosler. It is claimed that the .22 Nosler delivers 25% more case capacity and is nearly 90 m/s (300 ft/s) faster than a .223 Remington/ 5.56 NATO. The .22 Nosler is designed to use the existing bolt face of an AR-15, and conversions to this caliber can be ...
The 6.8mm Remington Special Purpose Cartridge (6.8 SPC, 6.8 SPC II or 6.8×43mm) is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command [6] to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines.
