The .30-06 Springfield caliber (decimal caliber 7.62 × 63 mm) is one of the most commonly used rifle calibers in Germany and worldwide, along with the German 8 x 57 IS caliber and the Anglo-Saxon .308 Winchester caliber.
Due to the wide distribution, almost all rifles are also offered in this caliber. The ammunition is also available everywhere and comparatively inexpensive.
".30" stands for the projectile diameter of 0.3 inch, "-06" for 1906, the year of introduction in the US Army.
The .30-06 Springfield caliber is closely related to the .308 Winchester cartridge, which has the same projectile diameter but is "shorter": .30-06 has a stronger propellant charge and therefore a longer cartridge case.
In direct comparison to .308, .30-06 is more rapid. This means due to the higher muzzle velocity, the projectile flies in a relatively stretched trajectory. In addition, it brings more energy to the target than .308. The disadvantage of the higher propellant charge: .30-06 has a stronger recoil, in anticipation of the same, shooters warp more easily when firing. As a result, .308 shots are often said to have higher accuracy. If a short, leaded barrel is used, the cartridge's potential may not be fully utilized because the propellant charge does not burn completely until the projectile leaves the barrel. This has the disadvantage of a strong muzzle flash and a very loud muzzle blast. For the .30-06 caliber, a barrel of 60 cm length is therefore recommended, or a special laboratory design for short barrels.
.30-06 Springfield can be used in Germany for hunting all cloven-hoofed game and is therefore also excellently suited for young hunters.
The next largest caliber in the ".30 group" is .300 Winchester Magnum (7.62 x 66.5 mm).
