Is There A Difference In Velocity Between Handloads And Factory Ammo?

Velocity Gains Through Handloading

Handloading allows for precision control over powder charge weight, which can result in significant velocity gains compared to factory ammunition. For example, a .308 Winchester handload using 46 grains of Varget powder and a 150-grain bullet can reach velocities of around 2,800 feet per second (fps), while a factory 150-grain .308 Winchester load might top out around 2,600-2,700 fps. This difference in velocity can be attributed to the ability to fine-tune the load for optimal performance.

The Role of Rifle and Barrel in Velocity

The velocity of both handloaded and factory ammunition can also be influenced by the rifle and barrel used. A well-tuned barrel with a consistent chamber and throat can help to optimize the performance of both handloads and factory rounds. In contrast, a barrel with significant wear or imperfections can cause velocity losses across the board. For instance, a barrel with a 1 in 10-inch twist rate may be better suited for longer, heavier bullets, which can result in improved accuracy and velocity.

Measuring and Comparing Velocity

To accurately compare the velocity of handloads and factory ammunition, it’s essential to use a reliable chronograph or Doppler radar system. These tools can provide precise measurements of bullet velocity, allowing hunters and shooters to identify any potential issues with their loads. When comparing handloads to factory ammunition, it’s also crucial to control for other variables, such as environmental conditions and rifle setup. By doing so, shooters can gain a more accurate understanding of the performance differences between handloads and factory rounds.
