Choosing the right caliber for target shooting or small game hunting can feel overwhelming. Two popular choices often debated are the 5.7x28mm and the .17 HMR. While both offer impressive accuracy and stopping power within their respective niches, they cater to different needs and preferences. This in-depth comparison will help you determine which cartridge best suits your shooting goals.
Understanding the Contenders: 5.7x28mm vs .17 HMR
Before diving into the specifics, let's establish a foundational understanding of each cartridge:
5.7x28mm: High-Velocity, Versatile Powerhouse
The 5.7x28mm, often associated with the FN P90 and PS90, is a high-velocity cartridge known for its flat trajectory and significant penetration. Developed for personal defense and military applications, its small size belies its considerable stopping power. It’s also gaining popularity among enthusiasts for its accuracy at longer ranges.
.17 HMR: High-Velocity, Accurate Small Game Cartridge
The .17 HMR (.17 Hornet Magnum) is a popular choice for varmint hunting and target shooting. Its high velocity and flat trajectory make it ideal for precise shots at small game, offering excellent accuracy at longer distances than many other rimfire cartridges. Its relatively low recoil makes it suitable for beginners and experienced shooters alike.
Key Differences: A Head-to-Head Comparison
Here's a breakdown of the key differences, helping you weigh the pros and cons of each cartridge:
| Feature | 5.7x28mm | .17 HMR |
|---|---|---|
| Caliber | 5.7x28mm | .17 HMR (5.6mm) |
| Cartridge Type | Centerfire | Rimfire |
| Velocity | Significantly higher (over 2000 fps) | High velocity (over 2500 fps) |
| Recoil | Noticeable, but manageable | Very low |
| Power | High penetration, stopping power | Excellent for small game, limited penetration |
| Cost | Higher ammunition cost | Lower ammunition cost |
| Applications | Personal defense, target shooting, small game hunting (with limitations) | Varmint hunting, target shooting, plinking |
| Availability | Widely available, but can be more expensive | Widely available, generally less expensive |
5.7x28mm: Strengths and Weaknesses
Strengths:
- Exceptional Penetration: The 5.7x28mm offers significantly greater penetration than the .17 HMR, making it effective against larger targets.
- Flat Trajectory: Its high velocity results in a flatter trajectory, improving accuracy at longer ranges.
- Accuracy: Capable of exceptional accuracy with appropriate firearms and ammunition.
Weaknesses:
- Higher Cost: Ammunition for the 5.7x28mm is generally more expensive.
- More Recoil: Experienced shooters will find the recoil manageable, but it may be significant for beginners.
- Overkill for Small Game: Its power can be excessive for many small game hunting applications, leading to potential damage to the meat.
.17 HMR: Strengths and Weaknesses
Strengths:
- Low Recoil: Extremely low recoil makes it ideal for beginners and comfortable for extended shooting sessions.
- High Accuracy: Exceptional accuracy at longer ranges for a rimfire cartridge.
- Affordable Ammunition: Relatively inexpensive ammunition compared to the 5.7x28mm.
- Excellent for Small Game: Ideal for varmint hunting, providing humane dispatch of small animals.
Weaknesses:
- Limited Penetration: Penetration is significantly lower compared to the 5.7x28mm.
- Not Suitable for Larger Game: Insufficient power for larger animals.
- Limited Availability of Specific Ammunition: While widely available, specialized ammunition might be harder to find compared to the 5.7x28mm.
Conclusion: The Right Choice Depends on Your Needs
Ultimately, the "better" cartridge depends entirely on your intended use. The 5.7x28mm excels in situations requiring significant penetration and accuracy at longer ranges, making it suitable for target shooting and certain small game hunting applications (though overpenetration can be an issue). The .17 HMR is the superior choice for varmint hunting and target practice where high accuracy and low recoil are priorities, but its limited penetration makes it unsuitable for larger game. Consider your specific needs, budget, and experience level before making your decision.
