.30-06 Spring. Ladedata

The .30-06 Springfield, commonly known as .30-06, is a storied rifle cartridge with a rich history, having been developed in the early 20th century. Officially adopted by the United States military in 1906, it succeeded the .30-03 Springfield and was used extensively through both World Wars and into the Korean War. This cartridge remains popular among hunters and sports shooters due to its versatile performance.

Technically, the .30-06 features a bullet diameter of 0.308 inches (7.82mm) and a case length of 2.494 inches (63.3mm). The cartridge overall length is typically about 3.34 inches (84.8mm), allowing for substantial powder capacity and thus varied ballistic performance. It can be loaded with bullet weights ranging from 110 to 220 grains. However, a practical reloader commonly employs bullet weights between 150 and 180 grains for optimal versatility in most applications.

Ballistically, the .30-06 boasts a flat trajectory and significant energy retention, making it suitable for long-range shooting. Standard muzzle velocity for a 150-grain bullet is approximately 2,900 feet per second, with a corresponding energy of about 2,820 foot-pounds, showcasing its capability to take down medium to large game.

Reloaders appreciate the .30-06 for its abundance of load data and variety of components available. Its relatively large case allows for experimentation in powder types and bullet seating depths, facilitating the crafting of loads tailored to specific firearms and applications, from target shooting to big game hunting. Furthermore, the widespread use of the .30-06 ensures that brass and reloading tools are readily accessible. This versatility and adaptability are key advantages that continue to make the .30-06 a favorite among ammunition reloaders worldwide.
