A Brief History
Charles Newton designed the .250-3000 Savage sleeve specifically for the lever rifle . Newton advised to equip cartridges with 6.5 g bullets, which would allow to reach a speed of 850 m / s, but Savage Arms reduced the mass of the bullet to reach a speed of 910 m / s, thus making it the first American cartridge to reach this speed. Achieving this speed may be the reason for choosing a lightweight 5.6 g bullet for a given caliber [3] . Newton questioned that the advertised increase in speed would lead to a decrease in penetration in the bodies of large animals [4] .
The American set the maximum pressure for this cartridge at 45,000 . Although this cartridge is inferior in power to the larger , but it produces less noise and has less impact. The characteristics are very close to .257 Roberts . Perhaps this cartridge is generally more suitable for hunting than the more popular .30-30 Winchester , but in recent years it has been squeezed by .257 Roberts and more flatbed 6 mm cartridges, such as .243 Winchester [3] , etc.
Currently, very few new weapons are produced under the .250 Savage. This cartridge has moderate returns and is well suited for hunting small game and deer [1] .
Options
Some rodent hunters use an improved version of the cartridge, known as .250 Ackley or .250 Improved or .250 Ackley Improved , as a dual-purpose cartridge for medium-range shooting. .250 Ackley is characterized by a steeper slope of the sleeve and straightened (ie, having less taper ) side walls - to increase the internal volume of the sleeve to accommodate a larger charge of gunpowder [5] . This allowed an increase in speed of more than 76 m / s compared to factory cartridges.
