Reloading your own 308 Winchester ammunition offers significant advantages: cost savings, the ability to tailor loads to your specific rifle, and the satisfaction of crafting your own precision rounds. However, it's crucial to approach reloading with meticulous attention to detail and a deep understanding of safety procedures. This guide provides comprehensive 308 Winchester reloading data, emphasizing safety and accuracy. Always consult your firearm's manual and follow recommended load data from reputable sources before attempting to reload ammunition.
Understanding 308 Winchester Reloading
Before diving into specific data, let's establish a foundation. Reloading involves four key steps:
-
Case Preparation: This includes cleaning, resizing, and depriming spent cases. Consistent case preparation is vital for reliable and accurate reloading.
-
Powder Charging: Accurately measuring the correct amount of gunpowder is paramount. Using a scale is mandatory; even slight variations can lead to dangerous pressure increases or underpowered rounds.
-
Bullet Seating: Properly seating the bullet to the correct overall cartridge length (OAL) ensures reliable feeding and optimal accuracy. OAL is critical and must be carefully measured.
-
Crimping: Crimping secures the bullet in place and prevents it from shifting during firing.
Essential 308 Winchester Reloading Data Considerations
The following factors influence your 308 Winchester reloading data choices:
-
Rifle: Different rifles have different chamber dimensions and tolerances. A load that works perfectly in one rifle might be unsafe in another.
-
Bullet Weight: Heavier bullets generally require more powder, while lighter bullets require less.
-
Powder Type: Different powders burn at different rates, affecting pressure and velocity. Using the wrong powder can lead to dangerous pressure spikes.
-
Primer Type: Primer type influences ignition characteristics, but the impact on 308 Winchester reloading is less significant than powder and bullet choices.
-
Case Brand and Condition: Case consistency influences the final results.

| Bullet Weight (grains) | Powder Type | Powder Charge (grains) | Primer Type | OAL (inches) | Notes |
|---|---|---|---|---|---|
| 150 | IMR 4350 | 43.0 - 45.0 | Federal 210M | 2.800 | Start low, work up |
| 150 | Varget | 42.0 - 44.0 | Federal 210M | 2.800 | Start low, work up |
| 168 | IMR 4064 | 42.0 - 44.0 | Federal 210M | 2.810 | Start low, work up |
| 168 | Varget | 40.0 - 42.0 | Federal 210M | 2.810 | Start low, work up |
Note: This table represents a small subset of possible load combinations. Many other powder types and bullet weights are compatible with the 308 Winchester.
Safety Precautions: The Most Important Aspect of Reloading
-
Always wear safety glasses: Eye protection is essential to prevent injury from potential powder explosions or flying debris.
-
Work in a well-ventilated area: Gunpowder fumes can be harmful.
-
Use a powder scale: Accurate powder measurement is crucial for safety.
-
Never exceed maximum recommended loads: Overloading can cause catastrophic rifle damage and serious injury.
-
Inspect every round carefully: Check for any defects or inconsistencies before loading into your magazine.
-
Clean your rifle regularly: Proper rifle maintenance is key to safe and accurate shooting.
-
Consult multiple sources: Use reliable reloading manuals and cross-reference data to verify accuracy.
Conclusion: Responsible Reloading for Precision and Accuracy
Reloading 308 Winchester ammunition can be a rewarding experience, providing cost savings and the ability to fine-tune loads for your specific firearm. However, safety must be your top priority. Always adhere to strict safety procedures, consult multiple reputable sources for reloading data, and never exceed maximum recommended loads. By following these guidelines, you can safely and effectively reload 308 Winchester ammunition, enjoying enhanced accuracy and performance on the range.
