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 aim of .17 HMR was to supply a high-velocity, flat-shooting cartridge that might excel in varmint searching and goal capturing. It primarily took the prevailing .22 WMR case and necked it down to simply accept a a lot smaller .17-inch bullet. This innovation allowed for considerably greater muzzle velocities, resulting in flatter trajectories, diminished wind drift, and elevated efficient vary. The .17 HMR shortly gained reputation amongst hunters concentrating on small recreation, equivalent to prairie canine, squirrels, and rabbits, and is a favourite amongst goal shooters.

Trying to fireplace a smaller .172-inch bullet can result in disastrous penalties.
Though the cartridges use the identical base, the .17 HMR case is technically the identical as a .22 WMR, the bullets should not. Some firearms are choosy about headspacing, or how the casing sits inside the chamber. .17 HMR cartridges and .22 WMR cartridges could also be so shut in dimensions that there’s little or no margin for error.
One other essential distinction to concentrate on is the stress every cartridge generates. Whereas each function at comparatively low pressures in comparison with centerfire cartridges, the .22 WMR usually produces barely greater 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 meant firearm.
Why it’s Not Secure 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 may be a problem 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.

- Barrel Injury: 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 doubtlessly result in extra severe barrel erosion and cracking, which can require alternative of the barrel.
- Blowback: Essentially the most extreme threat is the potential for blowback. If the bullet doesn’t create a adequate seal within the barrel, the high-pressure gases from the firing spherical may escape, doubtlessly injuring the shooter.

The .17 HMR and .22 WMR cartridges, whereas sharing visible similarities, are basically totally different. Trying to interchange them places you and others in severe hazard.
