Understanding the Cartridges: .17 HMR vs. .22 WMR
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 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 increased muzzle velocities, resulting in flatter trajectories, diminished wind drift, and elevated efficient vary. The .17 HMR shortly gained recognition amongst hunters focusing on small sport, similar to prairie canines, squirrels, and rabbits, and is a favourite amongst goal shooters.
The Reign of the .22 WMR
The .22 Winchester Magnum Rimfire (.22 WMR), also known as the .22 Magazine, is a real traditional within the rimfire world. It has an extended historical past than the .17 HMR, launched within the mid-Fifties by Winchester. The .22 WMR was designed to supply a big step up in energy in comparison with the usual .22 Lengthy Rifle (.22 LR). It was initially supposed to be used in lever-action rifles, and it shortly discovered its place within the arms of hunters and goal shooters who wanted extra vary and hanging energy than the .22 LR might supply. Its recognition has endured as a result of its effectiveness in searching small sport and its suitability for plinking and leisure capturing.
Key Variations: A Nearer Look
Whereas each the .17 HMR and .22 WMR are rimfire cartridges, and outwardly they share the same look, the vital variations are what make them incompatible. These variations are basic to the protection of your firearm and the shooter.
Probably the most vital distinction between these two rounds lies within the bullet diameter. The .17 HMR makes use of a .172-inch bullet, whereas the .22 WMR makes use of a .224-inch bullet. This distinction, seemingly small, is the first motive why you can not interchange these cartridges. Your .22 WMR firearm’s barrel is designed to soundly include a .224-inch bullet. Trying to fireside 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 pay attention to is the strain every cartridge generates. Whereas each function at comparatively low pressures in comparison with centerfire cartridges, the .22 WMR sometimes produces barely increased chamber strain than the .17 HMR. Although this alone is not the important thing motive for incompatibility, it is a contributing issue that underscores the necessity for every spherical for use with its supposed firearm.
Why it’s Not Secure to Shoot .17 HMR in a .22 WMR Firearm
The Hazards of Misfires and Malfunctions
One of many first and most regarding points is the elevated threat of misfires and malfunctions. As a result of the .17 HMR bullet is smaller in diameter than what your .22 WMR barrel is designed for, the bullet might not seat accurately. The bullet might doubtlessly tumble within the barrel somewhat than gaining the steadiness wanted for accuracy, and doubtlessly, the shot might not even hearth. The rimfire ignition system depends on the firing pin hanging the rim of the cartridge. If the spherical is just not correctly seated, or the firing pin is unable to strike the rim with sufficient power, a misfire happens, which will be a problem by itself.
The potential for malfunctions goes past a easy failure to fireside. Think about the .172-inch bullet exiting the casing, partaking the rifling, after which not sealing the bore. The gases might doubtlessly escape across the projectile, resulting in inconsistent velocities and erratic bullet flight, which might injury the barrel and trigger damage to the shooter or bystanders.
The Threat of Harm and Weapon Failure
Past misfires, there’s the very actual risk of significant damage and injury to your firearm. When the smaller .17 HMR bullet is fired from a .22 WMR rifle, the next might occur:
- Bullet Fragmentation: The .172-inch bullet might not correctly have interaction the rifling within the .22 WMR barrel. It might doubtlessly fragment, and even disintegrate, mid-flight. This leads to a lack of ballistic stability and presents a threat to something that is perhaps within the bullets path.
- Barrel Injury: If the .17 HMR bullet fails to stabilize because it travels down the barrel, it could trigger injury to the rifling. This injury compromises accuracy and might doubtlessly result in extra severe barrel erosion and cracking, which can require alternative of the barrel.
- Blowback: Probably the most extreme threat 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 might escape, doubtlessly injuring the shooter.
These elements spotlight why it’s vital to by no means try to make use of ammunition that isn’t particularly designed on your firearm.

- Be aware of headspacing: At all times be aware of the headspacing of your ammunition. If the ammunition is unfastened within the chamber, it’s not protected to shoot.

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