Technical Overview of the .17 HMR Cartridge The .17 Hornady Magnum Rimfire (HMR) has had a significant impact on rimfire ballistics since its introduction in 2002. Developed by necking down a .22 Magnum case to take a .17 caliber bullet, it was designed to provide a high-velocity, flat-shooting alternative to traditional rimfire rounds. Ballistic Performance and Characteristics
: Due to the high velocity and the aerodynamic profile of the polymer-tipped bullets often used in this caliber, it is known for high levels of inherent accuracy. It is often capable of maintaining tight groups at 100 yards, making it a preferred choice for target shooting. buy 17 hmr
: The cartridge typically launches a 17-grain bullet at muzzle velocities exceeding 2,500 feet per second. This high velocity contributes to a very flat trajectory over distances where other rimfires begin to drop significantly. Technical Overview of the
: These are highly common for .17 HMR because the manual locking mechanism easily handles the cartridge's pressure while maximizing the accuracy potential of the round. It is often capable of maintaining tight groups
The cartridge's design requires specific engineering in the firearms that chamber it. Because it operates at higher pressures than standard .22 LR, various mechanical actions are utilized to ensure safe operation:
