History
Designed for the Savage Model 99 lever action, which required a shorter cartridge than .30-06. Achieved approximately 90% of .30-06 performance. Ordnance engineers studied it extensively when developing the T65 experimental cartridge that became .308 Winchester — the .300 Savage's case dimensions directly influenced the .308.
