The 300 Blackout cartridge, with its versatility and subsonic capabilities, has become a popular choice for both hunting and self-defense. The 160-grain bullet offers a unique balance of performance characteristics, making it a compelling option for subsonic loads. This guide provides comprehensive Lee load data for the 160gr bullet, focusing on safety, accuracy, and optimal performance. Always consult your reloading manual and follow all safety precautions before beginning any reloading process. This information is for guidance only and should not be considered a substitute for proper training and safe reloading practices.
Understanding 160gr 300BLK Loads
The 160-grain bullet in 300BLK is typically designed for subsonic applications, offering significant advantages in reduced noise and improved accuracy at shorter ranges. Its heavier weight contributes to greater energy transfer upon impact compared to lighter-weight projectiles at subsonic velocities. However, achieving optimal performance requires careful consideration of powder type and charge weight.
Key Factors Affecting Load Performance
Several factors significantly influence the performance of your 160gr 300BLK loads:
-
Powder Type: Different powders burn at different rates, significantly impacting velocity and pressure. Selecting the appropriate powder for your specific bullet weight and desired velocity is crucial. Powders known for their suitability with subsonic 300BLK loads include but are not limited to: Accurate Arms #9, Hodgdon Titegroup, and several others. Refer to your chosen manual for specific recommendations.
-
Powder Charge Weight: The amount of powder used directly correlates to pressure and velocity. Start at the minimum charge weight recommended in your reloading manual and work your way up gradually, carefully monitoring pressure signs. Never exceed the maximum recommended charge weight.
-
Primer Type: While the effect is less pronounced than powder selection, the primer type can slightly influence ignition and pressure. Use the primer type recommended in your reloading manual.
