.30-06 and .270 Colt Sauer Rifles

The .30-06 Springfield cartridge, commonly referred to simply as the ".30-06," has its roots in the late 19th and early 20th centuries. It was officially adopted by the United States military in 1906, hence the name, and quickly gained recognition as a versatile and effective cartridge for both military and civilian applications. The .30-06 was initially designed for the Springfield 1903 bolt-action rifle, and this combination soon became synonymous with American marksmanship.

  • Bullet Diameter: .308 inches
  • Case Length: 2.494 inches
  • Typical Bullet Weights: 150-220 grains
  • Muzzle Velocity: 2,700-2,900 feet per second (fps)
  • Muzzle Energy: 2,800-3,000 foot-pounds (ft-lbs)

The .30-06 is renowned for its versatility in hunting. It is capable of taking down a wide range of game, including deer, elk, moose, bear, and even some African species. Its larger bullet diameter and wide selection of bullet weights make it suitable for various hunting scenarios.

1973 to 1985, Colt contracted with J.P. Sauer to make these bolt action rifles. My 2 examples are .30-06 and .270.

The .270 Winchester cartridge was introduced in 1925 by Winchester Repeating Arms Company. While it has a shorter history compared to the .30-06, it has gained a strong following and is considered a classic cartridge in its own right.

The .270 Winchester is well-regarded for its flat trajectory and long-range capabilities. It is particularly popular for hunting deer and other medium-sized game due to its excellent accuracy and energy retention at longer distances.

  • Bullet Diameter: .277 inches
  • Case Length: 2.540 inches
  • Typical Bullet Weights: 130-150 grains
  • Muzzle Velocity: 2,900-3,100 fps
  • Muzzle Energy: 2,600-2,950 ft-lbs

The .30-06 offers a wider range of bullet weights, typically from 150 to 220 grains, making it more versatile for hunting larger game. The .270 Winchester typically uses bullets ranging from 130 to 150 grains, making it well-suited for medium-sized game.

The .270 Winchester generally has a slightly higher muzzle velocity and flatter trajectory compared to the .30-06, but the .30-06 often delivers more energy at the target due to its larger bullets and heavier bullet options.

While both cartridges are suitable for hunting, the .30-06 is better suited for larger game due to its greater bullet diameter and weight options. The .270 Winchester excels at taking down medium-sized game, making it a popular choice for deer hunters.

The .270 Winchester tends to have less recoil compared to the .30-06, which can be a factor to consider, especially for recoil-sensitive shooters. Both cartridges have widespread ammunition availability, but the .30-06 may offer a broader selection of loads and bullet types due to its longer history and popularity.

In conclusion, the choice between the .30-06 and .270 Winchester depends on the specific needs of the shooter or hunter. The .30-06 offers greater versatility for hunting larger game and has a longer history, while the .270 Winchester is well-suited for medium-sized game and offers a flatter trajectory. Ultimately, personal preference, intended use, and the specific characteristics of the rifle should guide the selection between these two classic cartridges.

The Colt Sauer Serial Numbers
Note Letters in Serial Number
The first 18,000 rifles had a prefix of CR letters in the serial number.

Years of DOM           Begin
1973 - 1978 CR0001 CR18000 18,000
1979 - 1985 ?????? ??????? ?????
This bolt action rifle was manufactured just twelve years (1973-1985), by JP Sauer of Germany for Colt.

According to my serial number research, only 18,000 rifles were produced from 1973 through 1978. I don't have the serial number ranges after 1978, but since Colt has published their Serial Number Lookup Database, it is very easy to identify your gun.
