It is capable of reaching over 4,000 feet per second.
Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]
The Ruger Hawkeye is a single-shot pistol chambered for the .256 Winchester Magnum cartridge, produced by Sturm, Ruger & Co. from 1963 until July 1964.

The 52-grain bullet can be pushed out of the muzzle at over 3,500 feet per second (1,100 m/s), placing the .22 PPC in the varmint and small game class. A 1 in 14-inch (1 in 355 mm) twist has become pretty much standard for these rifles although 1 in 12-inch (1 in 305 mm) twist will sometimes be found, depending on the load and bullet weight.

To obtain maximum accuracy, bullet weight and form are matched to the rifling twist rate of the barrel. Typically, 68 gr (4.41 g) bullets are used in barrels with twist rates of 1 in 13 inch (1 in 330 mm), while 1 in 15 inch (1 in 380 mm) barrel twists can accommodate lighter 58 or 60 gr (3.76 or 3.89 g) accurately.
