.17 Hornady Magnum Rimfire, commonly known as the .17 HMR, is a rimfire rifle cartridge developed by the ammunition company Hornady in 2002. It was developed by necking down a .22 Magnum case to take a .17 caliber (4.5 mm) projectile. Commonly loaded with a 17 grain (1.1 g) projectile, it can deliver muzzle velocities in excess of 775 m/s (2,650 ft/s).
The .17 Remington was introduced in 1971 by Remington Arms Company for their model 700 rifles. It is based on the .223 Remington case necked down to .172 in (4.37 mm), with the shoulder moved back. It was designed exclusively as a varmint round, though it is suitable for smaller predators. There are those such as P.O. Ackley who used it on much larger game, but such use is not typical. Extremely high initial velocity (over 4000 ft/s 1200 m/s), flat trajectory and very low recoil are the .17 Remington's primary attributes. It has a maximum effective range of about 440 yards (400 m) on prairie dog-sized animals, but the small bullet's poor ballistic coefficients and sectional densities mean it is highly susceptible to crosswinds at such distances.
