Decoding the .17 Caliber World: How Many Are There?
The question "How many .17 calibers are there?" isn't easily answered with a single number. The .17 caliber designation refers to a bullet diameter of approximately 0.172 inches (4.37 mm). However, the reality is far more nuanced, with numerous cartridges using this approximate diameter but differing significantly in other aspects like case length, powder charge, and intended application. This leads to a diverse range of .17 caliber rounds suitable for various purposes.
Instead of focusing on a precise count (which is difficult to definitively determine and prone to change with new cartridge introductions), let's explore the categories and key distinctions within the .17 caliber family. Understanding these categories will give you a much clearer picture of the .17 caliber landscape.
Categorizing .17 Calibers: More Than Just a Number
We can broadly categorize .17 caliber cartridges into several groups based on their intended use:
1. Rimfire Cartridges: These are generally smaller, lower-powered rounds, often favored for small game hunting, target shooting, and plinking. Popular examples include:
- .17 HMR (.17 Hornady Magnum Rimfire): A very popular choice known for its flat trajectory and relatively high velocity for a rimfire.
- .17 Mach 2: Another rimfire, offering decent accuracy and affordability.
- .17 WSM (.17 Winchester Super Magnum): While technically a rimfire, this round sits at the higher-powered end of the rimfire spectrum.
2. Centerfire Cartridges: Centerfire cartridges are generally more powerful than their rimfire counterparts, suitable for varmint hunting and longer-range shooting. This category boasts a larger variety:
- .17 Remington: An early centerfire option, less common now but still available.
- .17 Fireball: A small centerfire cartridge designed for varmint hunting.
- .17 Hornet: A relatively older cartridge gaining some renewed interest.
- .17 Winchester Super Magnum (WSM): Despite also appearing in the rimfire category (this highlights the complexities of categorizing by caliber alone!), this is a powerful centerfire cartridge.
Why the Variable Number?
The number of .17 caliber rounds isn't fixed due to several factors:
- Custom Loads: Experienced reloaders often create custom loads based on existing cases, further expanding the variety beyond commercially available cartridges.
- Regional Variations: Some cartridges may enjoy greater popularity in specific regions, leading to a perceived difference in "how many" exist.
- Obsoleted Cartridges: Older cartridges may become less common but not entirely disappear, making it tricky to compile a definitive total.
- Emerging Technologies: The firearms industry is constantly evolving; new cartridges are occasionally developed, adding to the total number.
Conclusion: Focus on Purpose, Not Just Count
Rather than obsessing over a precise count of .17 caliber cartridges, it's more beneficial to understand their applications and characteristics. Each cartridge within the .17 caliber family offers unique attributes regarding power, accuracy, cost, and intended purpose. Understanding these distinctions will help you choose the most suitable round for your specific needs. Researching individual cartridges based on your intended use is recommended for a deeper understanding.
