The name .28 Nosler refers to the first two digits in the caliber (0.284 in; 7.2 mm) of the bullets that the cartridge fires and the name of the company which created it.
The .28 Nosler is based on the .26 Nosler which was released in 2014. The .28 Nosler shares the same overall cartridge length of 84.8 mm (3.340 in) as the .26 Nosler which allows it to be chambered in standard-length action. This feature helps weight-conscious sportsmen to lighten their load before venturing into the backcountry. The cases’ overall length also aids in quick follow-up shots, since the bolt throw is shorter than on a magnum action.
Four of Nosler’s Cartridges the .26 Nosler, .28 Nosler, .30 Nosler, and the .33 Nosler are based on the same .300 Remington Ultra Magnum parent case. While the .26 Nosler and the .28 Nosler share the same cartridge case dimensions, the .30 Nosler has a slightly shorter length to the shoulder dimension than the .26 Nosler and the .28 Nosler, and the .33 Nosler has a shorter shoulder dimension yet than that of the .30 Nosler.
