The .30-03 Springfield (7.62×65mm) was a short-lived cartridge developed by the United States in 1903, to replace the .30-40 Krag in the new Springfield 1903 rifle. The .30-03 was also called the .30-45, since it used a 45 grain (2.9 g (0.10 oz)) powder charge; the name was changed to .30-03 to indicate the year of adoption. It used a 220 grain (14 g (0.49 oz)) roundnose bullet. It was replaced after only three years of service by the .30-06, firing a spitzer bullet that had better ballistic performance.
