[2] In 1915, Charles Newton designed the .250-3000 Savage case to fit the popular Savage Model 99 lever-action rifle, which unlike the previous lever actions had no problems with aerodynamic spitzer bullets thanks to its rotary magazine.

To facilitate handloading, casing geometry was based on the .30-06 Springfield, albeit shortened in order to fit into the aforementioned magazine designed for the .303 Savage.

[3] Newton questioned if the publicity over the advantages of velocity compensated for reduced penetration of the lighter bullet in larger game animals.

It is an excellent cartridge with moderate recoil for hunting small up to deer-sized game.

The .250 Ackley is the same basic cartridge with a steeper shoulder and with the sides blown-out or straightened to increase powder space.
