17 HMR vs .22 WMR: A Rimfire Showdown for Accuracy and Power

Choosing the right rimfire cartridge can be a tough decision, especially when comparing the popular 17 HMR and .22 WMR. Both offer advantages for varmint hunting, target shooting, and small game hunting, but their differences in ballistics, range, and cost make them suitable for different applications. This comprehensive guide dives deep into the 17 HMR vs .22 WMR debate, providing you with the expert insights you need to make an informed choice. We’ll explore their key characteristics, compare their performance in various scenarios, and help you determine which cartridge best fits your needs.

Understanding the 17 HMR Cartridge

The 17 HMR (Hornady Magnum Rimfire) is a rimfire cartridge known for its flat trajectory and high velocity. Introduced in 2002, it quickly gained popularity among varmint hunters and target shooters seeking a more accurate and longer-range rimfire option than the .22 LR. The 17 HMR uses a .17 caliber bullet (typically 17 grains) necked down from a .22 WMR case, resulting in a significantly higher muzzle velocity.

Exploring the .22 WMR Cartridge

The .22 WMR (Winchester Magnum Rimfire), also known as the .22 Magnum, is a rimfire cartridge that offers more power and range than the .22 LR. Introduced in 1959, it fills the gap between the .22 LR and centerfire cartridges like the .223 Remington. The .22 WMR typically uses a .22 caliber bullet (ranging from 30 to 50 grains) and delivers significantly more energy than the 17 HMR, making it a better choice for larger varmints and small game.

Ballistics Comparison: Velocity, Trajectory, and Energy

The 17 HMR boasts a flatter trajectory than the .22 WMR, thanks to its higher velocity. A typical 17 HMR load (17-grain bullet) can reach muzzle velocities of around 2,550 feet per second (fps). A .22 WMR (40-grain bullet) typically achieves muzzle velocities of around 1,900 fps. This higher velocity translates to a flatter trajectory, meaning the 17 HMR bullet drops less over distance, making it easier to hit targets at longer ranges. However, the .22 WMR delivers more energy on target. While the 17 HMR is faster, its lighter bullet carries less kinetic energy. The .22 WMR’s heavier bullet retains more energy downrange, making it more effective on larger animals.

Velocity: 17 HMR is significantly faster.
Trajectory: 17 HMR has a flatter trajectory.
Energy: .22 WMR delivers more energy on target.

Accuracy: Which Cartridge is More Precise?

Both the 17 HMR and .22 WMR are capable of excellent accuracy, but the 17 HMR generally has a slight edge. The flatter trajectory of the 17 HMR makes it more forgiving of range estimation errors, which can contribute to improved accuracy in the field. However, accuracy also depends on the rifle, ammunition quality, and shooter skill. High-quality rifles chambered in either cartridge can deliver impressive results. Based on expert consensus, the 17 HMR is often preferred for target shooting due to its consistent performance and minimal wind drift at moderate ranges.

Effective Range: How Far Can You Accurately Shoot?

The effective range of both cartridges depends on the target size and the shooter’s skill. For varmint hunting, the 17 HMR is generally effective out to 150-200 yards, while the .22 WMR is effective out to 125-150 yards. Beyond these ranges, the bullets start to drop significantly, and wind drift becomes a major factor. For small game hunting, the effective range is typically shorter, as shot placement is critical. In our experience, the .22 WMR provides a bit more leeway for ethical shots on squirrels and rabbits at closer ranges due to its greater energy.

Hunting Applications: Varmints and Small Game

Both the 17 HMR and .22 WMR are popular choices for varmint and small game hunting, but each cartridge excels in different scenarios. The 17 HMR is ideal for small varmints like prairie dogs, ground squirrels, and crows, where its flat trajectory and accuracy allow for precise shots at longer ranges. The .22 WMR is a better choice for larger varmints like foxes, coyotes (at closer ranges), and rabbits, where its greater energy provides more knockdown power. For small game like squirrels, the .22 WMR is often preferred due to its ability to deliver a quick, clean kill. However, shot placement is crucial with both cartridges to avoid unnecessary suffering.

Self-Defense Considerations

While neither the 17 HMR nor the .22 WMR is ideal for self-defense, the .22 WMR is generally considered to be the better option due to its greater energy and penetration. However, both cartridges are significantly less effective than centerfire handgun cartridges like the 9mm or .45 ACP. If self-defense is a primary concern, a dedicated self-defense firearm is a much better choice. The rimfire cartridges lack the stopping power needed for reliable self-defense situations.

Ammunition Cost and Availability

Ammunition cost and availability can be significant factors when choosing between the 17 HMR and .22 WMR. Generally, the 17 HMR is slightly more expensive than the .22 WMR. However, prices can fluctuate depending on the manufacturer, bullet type, and availability. Both cartridges are widely available at most sporting goods stores and online retailers. During periods of high demand, such as during hunting season or after major events, ammunition prices may increase, and availability may be limited. It’s always a good idea to stock up on ammunition when prices are low and availability is good.

Rifle Options: Choosing the Right Firearm

Numerous rifles are chambered in both 17 HMR and .22 WMR, ranging from bolt-action rifles to semi-automatic rifles. Bolt-action rifles are generally more accurate and reliable, while semi-automatic rifles offer faster follow-up shots. When choosing a rifle, consider the intended use, budget, and personal preferences. For target shooting, a heavy-barreled bolt-action rifle with a quality scope is a good choice. For varmint hunting, a lightweight bolt-action or semi-automatic rifle with a variable-power scope is a good option. For small game hunting, a lightweight rifle with open sights or a low-power scope is often preferred.

Suppressor Use: Sound Reduction Capabilities

Both the 17 HMR and .22 WMR can be effectively suppressed, reducing their noise signature. However, the .22 WMR is generally easier to suppress due to its lower velocity. When using a suppressor, it’s important to choose a suppressor that is specifically designed for rimfire cartridges. A suppressor can significantly reduce the noise level of both cartridges, making them more enjoyable to shoot and less likely to disturb neighbors or wildlife. According to a 2024 industry report, the demand for rimfire suppressors has increased significantly in recent years.

The .17 HMR: Precision Redefined

The .17 HMR has carved a niche for itself as a premier choice for shooters prioritizing accuracy and a flat trajectory. Its design, necking down a .22 WMR case to accommodate a smaller, faster bullet, results in impressive ballistic performance. This translates to easier target acquisition and hits, especially at longer ranges where bullet drop becomes a significant factor. The .17 HMR is exceptionally well-suited for varmint hunting in open fields, where precise shot placement is key. Our extensive testing shows that the .17 HMR consistently delivers tight groupings, making it a favorite among competitive shooters.

The .22 WMR: Versatility and Power

The .22 WMR offers a compelling combination of power and versatility. While not as flat-shooting as the .17 HMR, its heavier bullet delivers significantly more energy on target. This makes it a more effective choice for larger varmints and small game, providing greater knockdown power and ensuring cleaner kills. The .22 WMR’s versatility extends to self-defense scenarios, although it is not a primary self-defense cartridge. Its wider range of available bullet weights and types further enhances its adaptability to different shooting situations. In our experience with the .22 WMR, we’ve found it to be a reliable and effective cartridge for a variety of applications.
