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. [14] This feature helps weight-conscious sportsmen to lighten their load before venturing into the backcountry.
Handloaders using the SAAMI spec full length sizer, can be adapted to the older chambering, as Redding required use of a custom deeper shellholder (.014 deeper or .014 space between shellholder and bottom of die). Published loading data has increased as have bullets and powders, the original .280 Remington and the .280 Ackley variants are ...
The .280 Ackley Improved (.280 AI) was the result of the .280 Remington case modification by P.O Ackley, who pushed out the sidewalls at the shoulder to near parallel and steepened the shoulder angle to 40 degrees in order to increase powder capacity, thus along with increasing the allowable pressure, resulted in increasing the bullet initial velocity by approximately 100 fps.

Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
Since their release, the 26 Nosler and 28 Nosler [7] have been known for high muzzle velocities and extremely flat trajectories. The parent case for both cartridges is based on the .300 Remington Ultra Magnum [8] case. In October 2014, Nosler introduced Ballistic Tip Ammunition as the latest product offering in their factory loaded ammunition. [9]
This case has no belt, unlike many other magnum cartridges, which can be desirable for handloading because of possible problems with case head separation with repeated reloading of belted magnum cartridges. The rimless design also contributes to smooth feeding from the box magazine of bolt-action rifles.
The .257 Weatherby Magnum is capable of firing a 115 gr (7.5 g) Nosler Ballistic Tip bullet at 3,400 ft/s (1,036 m/s) generating 2,952 ft⋅lbf (4,002 J) of energy [3] which is comparable to factory loadings of the .30-06 Springfield and the .35 Whelen in terms of energy.
