History
Adopted with the M1903 Springfield as an improvement on the .30-40 Krag. Used a round-nose 220gr bullet typical of the era. When Germany adopted the S-Patrone spitzer bullet in 1905, achieving dramatically higher velocity and flatter trajectory, the Army hurriedly developed a new load — the .30-06 — with a 150gr spitzer. Every .30-03 rifle had to be re-chambered.
