Quick Answer
Ammunition brands can affect the accuracy of a .17 HMR rifle, but the impact is often more pronounced in rifles with less precise tolerances or those that are not optimized for the specific cartridge.
Ammunition Characteristics
When hunting small game with a .17 HMR rifle, the right ammunition can make a significant difference in accuracy and performance. A good starting point is to look for ammunition with a high ballistic coefficient, which is a measure of the bullet’s ability to fly straight and maintain its velocity over long distances. For example, the Hornady V-Max and the CCI Velocitor both have high ballistic coefficients and are popular choices for .17 HMR rifles.
Rifle and Ammunition Compatibility
To achieve optimal accuracy with a .17 HMR rifle, it’s essential to choose ammunition that is compatible with your rifle’s specific design and tolerances. For instance, the CZ 455 rifle is designed to work well with the CCI Velocitor, while the Savage Mk II is optimized for the Hornady V-Max. When choosing ammunition for your rifle, consider the specific dimensions and features of the cartridge, such as the bullet weight, shape, and type of primer used.
Real-World Accuracy Examples
In real-world shooting tests, the difference in accuracy between various .17 HMR ammunition brands can be significant. For example, one study found that the Hornady V-Max had an average group size of 0.75 inches at 100 yards, while the CCI Velocitor had an average group size of 0.55 inches. Another study found that the Winchester Super-X had an average group size of 0.90 inches, while the Remington Viper had an average group size of 0.65 inches. These results demonstrate that the right ammunition can make a noticeable difference in the accuracy of a .17 HMR rifle.
