Product Overview 280 Ackley Improved AMMO
The .280 Ackley Improved (.280 AI) was the result of the .280 Remington case modification by P.O Ackley, who steepened the shoulder angle to 40 degrees in order to increase powder capacity, thus increasing the bullet initial velocity by 100 fps.
Nosler Trophy Grade ammunition 280 is high quality, production-run ammunition manufactured to strict tolerances and inspected as it is hand-packaged. Trophy Grade features Nosler Custom brass and the dependable, high performing bullets you know and trust.
History
In 1957 Remington introduced the .280 Remington, which was based on the .30-06 Springfield case necked down to 7mm. The cartridge was intended to compete with the .30-06 and the .270 Winchester.
Although the .280 Remington is considered to be a very balanced cartridge combining the best attributes of both cartridiges due to the high ballistic coefficient and sectional density, characteristic of 7mm calibers, it did not reach the popularity achieved by the .30-06 and .270 Win.
In 2006, the famous wildcatter P.O Ackley, worked on the .280 Remington case in order to add it to its line of “Ackley Improved” cartridges and named it the .280 Ackley Improved 40 degrees. By 2008, Nosler standardized it and SAAMI accepted it. Ever since, the .280 Ackley Improved has earned great popularity in the US market. Actually different companies are chambering the .280 AI among its line of rifles, including the Ruger M77 Hawkeye, Savage 110, Browning X-Bolt and Weatherby Mark V.
Partition Bullets feature a fully tapered jacket that ruptures instantly at the thin jacket mouth, yet the gradual thickening along the bullet’s axis controls expansion and curls the jacket uniformly outward at high or low velocities. Nosler’s integral partition supports the expanded mushroom and retains the rear lead alloy core. The enclosed rear core retains more than half the original bullet weight for deep penetration. The special crimp locks in the rear core section, adding strength to resist deformation under the pressure of heavy magnums.
The .280 AI is basically the .280 Remington redesigned by steepening its case shoulder, thus resulting in an increased powder capacity giving 100 fps of muzzle velocity, comparable to the 7mm Remington Magnum.
The differences between the .280 Remington and the .280 Ackley improved are minimal. A .280 Remington cartridge fired from a rifle chambered in .280 Ackley Improved will result in a case formed for the latter, which may be used for reloading.
