The Rise of the .17 HMR
The .17 Hornady Magnum Rimfire (.17 HMR) is a comparatively new addition to the rimfire household, born out of a collaboration between Hornady and Sturm, Ruger. Launched on the flip of the millennium, the first purpose of .17 HMR was to supply a high-velocity, flat-shooting cartridge that might excel in varmint looking and goal capturing. It basically took the present .22 WMR case and necked it down to simply accept a a lot smaller .17-inch bullet. This innovation allowed for considerably larger muzzle velocities, resulting in flatter trajectories, decreased wind drift, and elevated efficient vary.

One other essential distinction to pay attention to is the stress every cartridge generates. Whereas each function at comparatively low pressures in comparison with centerfire cartridges, the .22 WMR usually produces barely larger chamber stress than the .17 HMR. Although this alone is not the important thing purpose for incompatibility, it is a contributing issue that underscores the necessity for every spherical for use with its supposed firearm.
Why it’s Not Protected to Shoot .17 HMR in a .22 WMR Firearm

The rimfire ignition system depends on the firing pin putting the rim of the cartridge. If the spherical just isn’t correctly seated, or the firing pin is unable to strike the rim with sufficient pressure, a misfire happens, which could be a difficulty by itself.
The potential for malfunctions goes past a easy failure to fireplace. Think about the .172-inch bullet exiting the casing, participating the rifling, after which not sealing the bore.

This ends in a lack of ballistic stability and presents a danger to something that is likely to be within the bullets path.
- Barrel Harm: If the .17 HMR bullet fails to stabilize because it travels down the barrel, it could trigger harm to the rifling. This harm compromises accuracy and might probably result in extra severe barrel erosion and cracking, which can require alternative of the barrel.
- Blowback: Probably the most extreme danger is the potential for blowback. If the bullet doesn’t create a enough seal within the barrel, the high-pressure gases from the firing spherical may escape, probably injuring the shooter.
