How to Use the HTC 310-225 RN for Optimal Results
To achieve the best performance from your HTC310-225 RN, follow these steps for a smooth and efficient bullet casting process.
1. Preparing the Mould
Before you start casting, it’s crucial to prepare the mould properly:
- Clean the mould – Use a mild degreaser to remove any factory residues.
- Preheat the mould – This prevents wrinkles in bullets and ensures proper fill-out.
- Apply a light sprue plate lube – Helps in smooth operation and extends mould life.
2. Selecting the Right Alloy
The choice of lead alloy impacts bullet hardness and performance:
- 96-2-2 Alloy (96% Lead, 2% Tin, 2% Antimony) – A great choice for subsonic loads.
- Straight Wheel Weights – Commonly used but may require additional tin for better fill-out.
- Soft Lead – Ideal for hunting applications due to better expansion.
3. Casting the Bullets
Follow these steps to cast perfect bullets:
- Heat the lead to 700-750°F (371-399°C).
- Pour steadily into each cavity, ensuring complete fill-out.
- Allow the bullets to cool slightly before opening the mould.
- Drop the bullets onto a soft towel to prevent deformities.
Bullet Coating Options for the HTC 310-225 RN
The HTC310-225 RN is designed for modern coating techniques, which enhance bullet performance and eliminate traditional lubing needs.
1. Powder Coating
Powder coating creates a durable polymer shell around the bullet, offering several advantages:
- Prevents barrel leading.
- Enhances lubricity and accuracy.
- Allows for color-coding different loads.
2. Hi-Tek Coating
Hi-Tek coating is another popular choice, especially for high-volume casters:
- Reduces smoke during firing.
- Improves bullet hardness.
- Eliminates the need for gas checks in certain applications.
Loading Data for the HTC 310-225 RN
Loading the HTC310-225 RN requires careful powder selection and load development for safety and performance.
1. Recommended Powders
- A1680 – Ideal for subsonic 300 Blackout loads.
- IMR 4198 – Provides consistent velocity with minimal pressure spikes.
- H110 – Works well for both subsonic and supersonic applications.
2. Charge Weights
Always start with conservative charge weights and work up while monitoring for pressure signs. Consult a reputable reloading manual for precise data.
3. Bullet Seating Depth and Crimping
- Seat the bullet to ensure proper chambering.
- Apply a light crimp for consistent ignition and accuracy.
Common Issues and Troubleshooting
Even the best moulds can present challenges. Here’s how to solve common problems:
- Wrinkled Bullets? – Increase mould temperature or adjust pour speed.
- Bullets Not Dropping Freely? – Lightly smoke the cavities or polish burrs.
- Poor Fill-Out? – Increase lead temperature or add a bit more tin.
Maintenance Tips for Longevity
Proper care extends the life of your mould:
- Clean after each session to remove lead buildup.
- Keep in a moisture-free environment to avoid oxidation.
- Lightly oil the mould when not in use (for storage).
Conclusion
