.256 Newton

Often though of as the father of high velocity, Charles Newton developed the .256 Newton in 1913 using the Springfield 30-06 as the parent cartridge. The .256 Newton was initially loaded by the Western Cartridge Company with a 129 grain bullet at 2760 fps. This was about a fast as it could be propelled with the powders of the day, as slow burning powders weren’t available until the 1940s.

The .256 Newton was well received by the shooting public, but with the outbreak of WW I, in 1914, the U.S. Army took over Newtons factory. By the end of 1917 Newton had used the last of his inventory and there was no market for his rifles. He was able to secure a loan to buy more machinery and tooling, but in April 1918 the bank foreclosed, and the company went into receivership.

The .256 Newton is capable of propelling a .265 dia. 123 gr. bullet at 3,105 fps with 2,632 ft. lbs. of energy.
