Parker Otto Ackley (May 25, 1903 – August 23, 1989) [1] was an American gunsmith, barrel maker, author, columnist, and wildcat cartridge developer. The Ackley Improved family of wildcat cartridges are designed to be easily made by rechambering existing firearms, and fireforming the ammunition to decrease body taper and increase shoulder angle, resulting in a higher case capacity.
Some varmint hunters use the improved version of this cartridge, known as the .250 Ackley, .250 Improved or .250 Ackley Improved as a dual-purpose intermediate-range cartridge.

Most rifle magazines had a capacity for 4 cartridges. The .222 Remington version could hold 5 cartridges and the larger .300 H&H Magnum and other similarly large cartridges were limited to 3 cartridges in the magazine. Barrels were tapered with lengths, depending on year and caliber, ranging from 22 to 26 inches.
Despite having a modern straight taper design, the round was eclipsed by the older .22-250 Remington, already a popular wildcat introduced commercially a year later. The .225 Winchester was chambered in factory rifles by Winchester (Models 70 and 670) and Savage (Model 340).
