Understanding Hornady's 300 Blackout Offerings
Hornady offers a wide range of projectiles designed for the 300 Blackout, each optimized for different applications. Their lineup includes:
- Subsonic bullets: Designed for suppressed use, these projectiles are specifically weighted and constructed to maintain subsonic velocities, minimizing noise. Look for Hornady's offerings in weights like 208 grains or even heavier.
- Supersonic bullets: Optimized for maximum range and velocity, these bullets are ideal for hunting or longer-range shooting. Weights typically range from 110 grains to 150 grains.
- Match grade bullets: Designed for extreme accuracy, these bullets often feature superior construction and consistency for improved precision.
- Expanding bullets: Designed for hunting applications, these bullets expand upon impact, maximizing stopping power and lethality.
Key Components for Reloading 300 Blackout with Hornady Components
Before delving into load data, let's cover the essential components:
- Hornady Bullets: Choose the bullet weight and type appropriate for your intended use. Consider factors like ballistic coefficient, intended range, and hunting regulations.
- Hornady Cases: Using quality brass cases ensures consistent performance and longevity. Hornady offers new brass specifically for 300 Blackout, ensuring optimal sizing and dimensions.
- Hornady Powders: Hornady offers a range of powders suitable for 300 Blackout, each with unique burn rates and characteristics. Selecting the correct powder is crucial for achieving optimal velocity and pressure. Popular choices often include Lil' Gun and other slower-burning powders for subsonic loads.
- Small Rifle Primers: Use small rifle primers; this is non-negotiable for proper ignition in 300 Blackout. Hornady primers are a reliable option.
Hornady 300 Blackout Load Data Examples (Disclaimer: This is sample data only. Always consult the latest Hornady reloading manual for the most accurate and up-to-date information.)
(Note: This is sample data and should not be used without consulting the current Hornady manual. Always start low and work up slowly, carefully monitoring pressure signs.)
| Bullet Weight (grains) | Powder (Type) | Powder Charge (grains) | Primer | COL (inches) | Notes |
|---|---|---|---|---|---|
| 125 | XMP (example) | 21.5 | Small Rifle | 2.260 | Start low, work up |
| 150 | Lil' Gun (example) | 10.0 | Small Rifle | 2.260 | Subsonic load |
| 208 | Unique (example) | 8.0 | Small Rifle | 2.260 | Subsonic load |
Crucial Considerations:
- Start Low and Work Up: Never start at the maximum load. Begin with the minimum listed charge and incrementally increase the powder charge while carefully observing pressure signs.
- Pressure Signs: Be aware of potential pressure signs such as excessively hard bolt lift, flattened primers, or unusual sounds from your firearm. If any pressure signs are observed, immediately cease reloading and reassess your load.
- Accurate Measurement: Use a reliable powder measure and scale to ensure consistent powder charges.
- Consistent Seating Depth: Maintain consistent bullet seating depth using a bullet seating die.
- Case Preparation: Prepare your brass correctly using appropriate sizing and trimming.
Safety First: The Golden Rule of Reloading
Reloading ammunition is inherently dangerous. Always prioritize safety: wear safety glasses and hearing protection, work in a well-ventilated area, and follow all manufacturer's instructions precisely. Improper reloading practices can lead to serious injury or death. Never exceed the maximum listed pressure.
