HTC 310-225 RN Bullet Mold: Specifications and Features

Before diving into load data, it’s important to understand the bullet’s characteristics and what makes it ideal for reloading.

• Caliber: .310 inches
• Weight: 225 grains
• Profile: Round Nose
• Base: Plain Base
• Intended Use: Powder Coating or Hi-Tek Coating
• Best Suited For: Subsonic loads in .300 AAC Blackout (300 BLK)

Why Choose HTC 310-225 RN?

This bullet mold is perfect for shooters looking for subsonic performance in semi-automatic platforms. The round nose profile ensures smooth feeding, while powder coating or Hi-Tek coating enhances performance by reducing lead fouling and improving barrel longevity. It’s especially useful for suppressor users, hunters, and target shooters who want quiet, effective, and accurate loads.

Choosing the Best Powder for HTC 310-225 RN Load Data

Selecting the right powder is one of the most critical decisions when working with HTC 310-225 RN bullets. The goal is to achieve a consistent, safe velocity while maintaining low pressure.

Top Powders for Subsonic Loads

• Accurate 1680: The best powder for subsonic 300 BLK, providing consistent pressures and reliable cycling in semi-automatic rifles.
• Hodgdon CFE BLK: Specifically designed for 300 BLK applications, ensuring clean burning, reliable ignition, and smooth cycling.
• IMR 4198: A slower-burning powder that excels in low-pressure subsonic loads.
• Shooter’s World Blackout: A popular new powder optimized for subsonic 300 BLK applications.

Best Powders for Supersonic Loads

• Hodgdon H110: Works well in higher-velocity 300 BLK applications, but is less effective in subsonic loads.
• Lil’ Gun: A versatile powder suitable for medium-velocity cartridges.

Key Aspects to Evaluate When Selecting a Powder

• Burn Rate: Faster-burning powders like H110 are great for supersonic loads, while slower-burning powders like Accurate 1680 are best for subsonic applications.
• Pressure Regulation: Powders like CFE BLK offer consistent pressure, ensuring reliable cycling in semi-autos.
• Residue and Clean Burning: Hodgdon CFE BLK and Shooter’s World Blackout produce less fouling, keeping barrels clean.

HTC 310-225 RN Load Data: Charge Weights and Velocities

For safe and effective reloading, always start with the minimum recommended charge and increase gradually, monitoring for pressure signs.

Recommended Load Data for 300 AAC Blackout (Subsonic)

Important Notes:

• Always cross-check load data with official reloading manuals.
• Adjust loads based on firearm type, barrel length, and environmental factors.
• If using a suppressor, ensure velocity stays below 1100 fps to prevent the supersonic crack.

Seating Depth and Cartridge Overall Length (COL)

Bullet seating depth is crucial for chambering reliability and pressure regulation.

• Recommended Cartridge Overall Length (COL): 2.120 inches
• Crimping: A light taper crimp is advised for semi-auto firearms to prevent bullet movement during cycling.

How to Achieve Proper Bullet Seating

• Perform a “plunk test” to ensure proper chamber fit.
• Avoid excessive crimping, which can distort the bullet and affect accuracy.
• Keep COL consistent to maintain uniform chamber pressure.

Case Preparation and Priming for HTC 310-225 RN

Proper case preparation ensures consistent ignition and cycling.

Step-by-Step Case Prep Process

• Cleaning: Remove carbon buildup with a tumbler or ultrasonic cleaner.
• Full-Length Resizing: Standardize cases for reliable chambering.
• Trimming: Keep 300 BLK cases under 1.368 inches.
• Chamfer & Deburr: Smooth case mouths allow for easy bullet seating.
• Priming: Use small rifle primers for reliable ignition.

Safety Considerations for HTC 310-225 RN Reloading

Safety should always come first when reloading. Follow these critical precautions:

• Start Low & Increase Gradually: Never begin with max loads.
• Monitor for Pressure Signs: Flattened primers, difficult extraction, or case head swipes signal excessive pressure.
• Store Powder & Primers Safely: Keep in a cool, dry location away from open flames.
• Use a Digital Scale: Precise measurements prevent dangerous overcharges.

HTC 310-225 RN: Performance Insights and Best Applications

Ideal Use Cases

• Subsonic Suppressed Shooting: Best for quiet, accurate shooting in suppressed 300 BLK rifles.
• Hunting Applications: Effective for medium game like hogs and deer.
• Target Shooting & Plinking: Provides affordable and consistent accuracy.

Optimizing Accuracy

• Shorter barrels (8-10 inches) improve subsonic performance.
• A 1:7 or 1:8 twist rate stabilizes heavy bullets effectively.
• Using a chronograph helps fine-tune velocity and consistency.

Conclusion: Reload HTC 310-225 RN with Confidence

Reloading HTC 310-225 RN bullets is an effective way to enhance shooting performance, whether for suppressor use, hunting, or target shooting. By following accurate load data, choosing the right powder, and practicing safety protocols, you can achieve consistent, reliable performance.

Key Takeaways

• Accurate 1680 and Hodgdon CFE BLK are top powders for subsonic loads.
• Maintain a consistent COL of 2.120 inches for best chambering results.
