The .30-06 Springfield cartridge is generally considered larger than the .303 British cartridge. The .30-06 has a bullet diameter of .308 inches and a case length of 63mm, while the .303 British has a bullet diameter of .311 inches and a case length of 76.2mm. However, in terms of overall length and power, the .30-06 is typically more powerful and has a longer effective range. Thus, while the .303 British has a larger bullet diameter, the .30-06 is larger in terms of case size and ballistic performance.
