The 223 Wylde chamber was developed to reliably fire both rounds with the highest possible accuracy (556 NATO ammo can safely be used in 223 Wylde barrels). The 223 Wylde chamber was desiged to have tighter tolerences and be slighty more accurate than the 556 NATO chamber. Both rounds maintain supersonic speed beyond 500 yards and maintains the capability of penetrating 0.135" steel at 500 yards.
