The 6.8 SPC (Special Purpose Cartridge) has gained popularity among shooters for its accuracy, versatility, and effectiveness in various applications. Reloading your own 6.8 SPC ammunition offers significant advantages, including cost savings, the ability to fine-tune loads for specific needs, and the satisfaction of creating your own precision ammunition. This guide provides comprehensive reloading data for the 6.8 SPC, emphasizing safety and accuracy. Remember, always prioritize safety when reloading ammunition. Consult your reloading manual and manufacturer's specifications before beginning.
Understanding 6.8 SPC Ballistics
Before diving into reloading data, let's understand the 6.8 SPC's ballistics. This cartridge balances performance and recoil, making it suitable for both hunting and tactical applications. Its larger diameter and heavier bullets compared to the 5.56 NATO provide greater energy transfer and improved downrange performance.
- Key Ballistic Features:
- Increased stopping power compared to 5.56 NATO.
- Flatter trajectory than 5.56 NATO at longer ranges.
- Moderate recoil, manageable for most shooters.
- Suitable for a wide range of bullet weights and types.
Here's a simple table comparing 6.8 SPC to 5.56 NATO:
| Cartridge | Bullet Weight (grains) | Muzzle Velocity (fps) | Energy (ft-lbs) |
|---|---|---|---|
| 6.8 SPC | 110 | 2700 | 1350 |
| 5.56 NATO | 55 | 3200 | 1200 |
(Note: Values are approximate and vary based on barrel length, powder, and other factors.)
Gathering Your Reloading Supplies
Reloading 6.8 SPC requires specific tools and components. Ensure you have everything you need before you begin. Improper equipment can lead to dangerous malfunctions.
- Essential Equipment:
- Reloading Press: A progressive press is efficient for large batches, while a single-stage press provides more control.
- Dies: A full set of 6.8 SPC dies (sizing, powder, bullet seating, and crimping).
- Powder Measure: A reliable powder measure ensures consistent powder charges.
- Scale: An electronic scale is crucial for precise powder weighing.
- Case Trimmer: To ensure consistent case length.
- Bullet Puller: For removing bullets from misloaded cartridges.
- Primer Seating Tool: For safely seating primers.
- Case Lubricant: Reduces friction during sizing.
Step-by-Step Reloading Process for 6.8 SPC
The reloading process involves several precise steps. Consistency is paramount to ensure safe and accurate ammunition.
-
Case Preparation: Clean, inspect, and deprime spent cases. Trim cases to the correct length using a case trimmer.
-
Sizing: Resize cases to the correct dimensions using the sizing die. Lubrication is crucial here to prevent case damage.
-
Powder Charging: Carefully measure and dispense the correct powder charge using a powder measure and scale. Double-check your powder charge before seating a bullet.
-
Primer Seating: Seat primers firmly and evenly using a primer seating tool.
-
Bullet Seating: Seat the bullet to the correct depth using the bullet seating die. Ensure proper bullet alignment and crimping.
-
Crimping: Crimp the case mouth to secure the bullet.
-
Inspection: Inspect each round carefully for any defects before storage.

This table provides example data, but you must consult your specific reloading manual and powder manufacturer's data sheets for accurate load data before reloading. Variations in brass, bullets, and environmental factors can affect results.
Troubleshooting Common Reloading Issues
Troubleshooting is a crucial aspect of reloading. Understanding potential problems and their solutions ensures safe and successful reloading.
-
Stuck Cases: Insufficient case lubrication can lead to stuck cases. Use proper lubrication techniques.
-
Squib Loads: Insufficient powder charge results in a squib load (bullet not fully propelled). Always double-check your powder charges.
-
Inconsistent Accuracy: Inconsistent powder charges, improper bullet seating, or variations in case preparation can lead to inaccurate shots.
Conclusion: Safe and Accurate 6.8 SPC Reloading
Reloading 6.8 SPC ammunition can be a rewarding experience. However, safety must always be the top priority. Carefully follow instructions, consult your reloading manual, and always double-check your work before firing any reloaded ammunition. Proper technique and attention to detail will result in safe, accurate, and cost-effective ammunition. Remember to always start low and work up when developing loads. Never exceed maximum recommended loads from your powder manufacturer's data.
