.28 Nosler

The .28 Nosler is a relatively recent addition to the world of high-performance rifle cartridges, introduced by Nosler, Inc. in 2015. Born out of the desire to maximize the potential of the .26 Nosler case, the .28 Nosler utilizes a slightly larger caliber, 7mm (.284 inch), to deliver impressive velocities and downrange energy. Nosler aimed to create a round that capitalizes on the popularity of 7mm projectiles, offering superior long-range capability with relatively manageable recoil. By designing the cartridge around a non-belted, rebated rim case derived from the .300 Remington Ultra Magnum, Nosler was able to optimize both case capacity and feeding reliability, making the .28 Nosler a standout choice for shooters who demand top-tier ballistic performance.

Among ammunition reloaders, the .28 Nosler has developed a reputation for its versatility and consistent performance, especially in applications demanding extreme accuracy and power. The cartridge shines in a broad spectrum of uses, from long-range target shooting to all manner of hunting scenarios. Precision shooters appreciate the round’s ability to maintain high velocity and flat trajectories over extended distances, with minimal wind drift due to high ballistic coefficient projectiles. The .28 Nosler has found a strong following among those looking for a magnum-level 7mm cartridge that doesn’t require the heavier weight or longer action of some classic competitors like the 7mm Remington Ultra Magnum or .300 Winchester Magnum, making it ideal for both custom and factory bolt-action rifles.

When it comes to hunting applications, the .28 Nosler is widely regarded as one of the most effective 7mm cartridges for North American big game. Its high velocity and energy transfer make it suitable for hunting a diverse range of species, including elk, moose, mule deer, pronghorn, and even black bear. The .28 Nosler’s ability to push high-BC bullets at magnum speeds ensures deep penetration and effective terminal ballistics at both medium and long ranges. Many hunters choose the .28 Nosler for Western hunts where longer shots are common and bullet drop needs to be minimized. The flat trajectory and strong energy retention also make it a go-to option for culling predators and for use in mountainous terrain, where shots can often exceed 400 yards.

Reloaders have a wide variety of bullet weights and styles to choose from when loading for the .28 Nosler. Typical bullet weights range from 120 grains for varmints and small game, up to 175 grains for larger game and long-range target shooting. The most popular bullet weights for hunting applications tend to fall between 150 and 175 grains, offering a balance between expansion, penetration, and external ballistics. Premium bullet choices—such as Nosler AccuBond, Hornady ELD-X, Berger VLD, and Barnes TTSX—allow reloaders to tailor loads for specific hunting or competition needs. The .28 Nosler’s generous case capacity accommodates a wide range of slow-burning powders like H1000 and Retumbo, enabling reloaders to safely reach impressive muzzle velocities in excess of 3,100 fps with heavier bullets. Standard barrel twist rates are typically 1:9, which further supports the use of long, high-BC projectiles.

Reloaders appreciate that, despite its magnum performance, the .28 Nosler can be chambered in standard-length actions, offering better handling and reduced rifle weight compared to cartridges requiring longer actions. The .28 Nosler operates at a maximum SAAMI pressure of 65,000 psi, contributing to its high performance without excessively shortening barrel life when loaded within standard limits. With the right components and careful load development, reloaders can unlock the full potential of this efficient and modern magnum caliber, making the .28 Nosler a favorite among those seeking both versatility and outstanding ballistic performance in their custom or factory hunting rifles.
