The 300 PRC (Precision Rifle Cartridge) has rapidly gained popularity among long-range shooters for its exceptional accuracy and ballistic performance. This guide provides comprehensive reloading data for the 300 PRC, focusing on safety, precision, and achieving optimal results. Remember: Always prioritize safety and consult your specific reloading manual before undertaking any reloading projects. The data presented here is for informational purposes only and should not be considered a substitute for proper instruction and safety precautions.
Understanding 300 PRC Ballistics
Before diving into reloading data, understanding the 300 PRC's ballistic characteristics is crucial. This cartridge boasts a flatter trajectory and less wind drift compared to many other popular calibers at longer ranges, making it ideal for precision shooting at extended distances. This is largely due to its efficient case design and ability to handle heavier bullets effectively.
Essential Reloading Equipment
Accurate and safe reloading requires the right equipment. You'll need:
- Reloading Press: A single-stage or progressive press capable of handling the 300 PRC cartridge.
- Dies: Full-length sizing die, expanding die, seating die, and possibly a crimp die.
- Case Trimmer: Essential for maintaining consistent case length.
- Powder Measure: Accurate powder dispensing is vital for consistent performance.
- Scale: A digital powder scale ensures precise powder charges.
- Bullet Puller: For safely removing bullets from loaded cartridges if necessary.
- Safety Equipment: Safety glasses and hearing protection are mandatory.
300 PRC Reloading Data Considerations
Several factors influence 300 PRC reloading data, including:
- Bullet Weight: Heavier bullets generally require more powder and result in higher velocities, but also increase recoil. Popular bullet weights range from 208 grains to 230 grains.
- Powder Type: Different powders burn at different rates, impacting velocity and pressure. Popular choices include Retumbo, H1000, and other magnum rifle powders. Always consult the manufacturer's data for specific powder recommendations.
- Primer Type: Large rifle magnum primers are typically used.
- Case Capacity: Slight variations in case capacity can affect pressure and velocity. Consistent case preparation is essential.
- Rifle Characteristics: Your rifle's specific chamber dimensions and barrel twist rate will influence optimal load data.

| Bullet Weight (grains) | Powder Type | Powder Charge (grains) | Primer Type | COL (inches) | Notes |
|---|---|---|---|---|---|
| 212 | Retumbo | 85.0 | Large Rifle Magnum | 2.850 | Start Low, Work Up |
| 215 | H1000 | 82.0 | Large Rifle Magnum | 2.860 | Start Low, Work Up |
Safety Precautions: A Critical Reminder
- Always wear safety glasses and hearing protection.
- Never exceed maximum recommended loads.
- Carefully inspect every component before loading.
- Start with minimum loads and gradually work up to find your optimal load.
- Observe for any pressure signs, such as flattened primers or excessive case expansion.
- Keep your reloading area clean and organized.
- Store ammunition properly.
