Choosing the right rimfire cartridge can significantly impact your shooting experience. The 17 Mach 2 and 17 HMR are both popular choices, but they cater to different needs and preferences. This in-depth comparison will help you decide which cartridge best suits your shooting style and goals.
Ballistics: Power and Performance
The most significant difference between the 17 Mach 2 and 17 HMR lies in their ballistic performance. The 17 HMR (Hornady Magnum Rimfire) boasts considerably more power, delivering significantly higher velocity and energy.
-
17 HMR: This round packs a punch, offering significantly higher muzzle velocities (typically around 2550 fps) compared to the 17 Mach 2. This translates to a flatter trajectory, longer effective range, and greater penetration power. It's a favorite for small game hunting and varmint control.
-
17 Mach 2: This cartridge is a milder performer, with lower muzzle velocities (around 2000 fps). This makes it a great choice for plinking, target shooting, and pest control at shorter ranges. It's generally less expensive to shoot.
| Feature | 17 HMR | 17 Mach 2 |
|---|---|---|
| Muzzle Velocity | ~2550 fps | ~2000 fps |
| Energy | Significantly Higher | Significantly Lower |
| Effective Range | Longer | Shorter |
| Recoil | Noticeably Higher | Lower |
| Cost | Generally More Expensive | Generally Less Expensive |
Accuracy and Precision
Both cartridges are known for their accuracy, but the 17 HMR generally provides a tighter grouping at longer ranges due to its higher velocity and flatter trajectory. However, the 17 Mach 2 is perfectly adequate for most target shooting and plinking needs at closer distances. The accuracy of both ultimately depends on the firearm, ammunition quality, and the shooter's skill.
Cost and Availability
Ammunition for the 17 HMR is typically more expensive than that for the 17 Mach 2. This cost difference is largely due to the higher manufacturing costs associated with the more powerful cartridge. However, both cartridges are readily available at most sporting goods stores and online retailers.
Rifle Compatibility
Finding rifles chambered in 17 HMR is relatively easy; they are widely manufactured by numerous companies. The 17 Mach 2, while also available, has a smaller selection of compatible rifles. Consider this factor when making your decision.
Applications: What's Each Best For?
-
17 HMR: Ideal for small game hunting (squirrels, rabbits), varmint control (groundhogs, prairie dogs), and longer-range target shooting.
-
17 Mach 2: Best suited for plinking, close-range target shooting, and pest control at shorter ranges. It’s also an excellent option for new shooters due to its lower recoil.
Conclusion: Making the Right Choice
The best cartridge for you depends entirely on your intended use. If you need the power and range for small game hunting or longer-range shooting, the 17 HMR is the clear winner. If you're looking for a less expensive, lower-recoil option for plinking, target practice, or close-range pest control, the 17 Mach 2 will likely be more suitable. Consider your budget, shooting style, and intended applications before making your choice. Remember to always practice safe firearm handling.
