The .28 Nosler is a 7 mm (.284″) caliber, rebated-rim centerfire rifle cartridge designed by Nosler. Introduced in 2015  and approved by SAAMI on January 19, 2015. It is the second cartridge designed by Nosler
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 aid 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.
The .28 Nosler is essentially a shortened version of the 7mm Remington Ultra Magnum (7mm RUM). They share a maximum body diameter of 14.0 mm (0.550 in). Rebating the rim to 13.6 mm (0.534 in) simplifies the production of rifle bolts since the rims of Holland & Holland-style belted magnums, such as the 7mm Remington Magnum and .300 Winchester Magnum, are the same diameter. Whereas the 7mm RUM case measures 60.6 mm (2.387 in) long from head to body-shoulder juncture, that dimension on the .28 Nosler case is 55.0 mm (2.166 in). The dimension at that point on the .28 Nosler case is 0.051 mm (0.002 in) larger, and that reduces its body taper by just a tad. Maximum case lengths are 72.4 mm (2.850 in) and 65.8 mm (2.590 in) respectively. Shoulder angles are 30 degrees for the Remington cartridge and a slightly sharper 35 degrees for the Nosler. Due to its greater length, the Remington case is about 25 percent more capacious than the Nosler.
Since the .28 Nosler burns smaller powder charges than the 7mm RUM, barrel accuracy life is potentially a bit longer. How much longer depends on a number of things, including barrel quality and whether a barrel is regularly cleaned and serviced or abused by its owner.
