Winchester’s current product page identifies this load as USA223R1. The earlier AUSAA223R1L value was distributor notation rather than the manufacturer’s published symbol and has been corrected.

Winchester USA223R1 is the current official identity for the 55-grain USA White Box 223 Remington FMJ load. Winchester lists 3,240 fps muzzle velocity, 1,282 ft-lb muzzle energy, and a G1 BC of 0.255.
Official Ballistics

Winchester publishes the muzzle values and G1 BC for USA223R1 but does not show a complete downrange table in the verified product listing used here. No trajectory or wind values are added.
Bullet and Load Design
The full-metal-jacket bullet is designed for positive functioning and range accuracy without controlled expansion. Winchester places the load in its value-oriented USA White Box line.
Best Uses
This load is intended for target shooting, training, and recreational range use. It is not a purpose-built expanding hunting load.
Reliability Notes
The official product page describes consistent performance, but firearm-specific function still needs to be confirmed in the individual rifle and magazine.
