A Word of Caution Before We Begin
Reloading ammunition is inherently dangerous. If you're new to reloading, it's crucial to invest time in learning the process thoroughly. Always follow the reloading manual's instructions precisely, and start with minimum loads, gradually working up to desired velocities.
Never exceed maximum loads listed in reloading manuals. Doing so can lead to catastrophic equipment failure and personal injury.
Finding Load Data for .308 with 178gr ELDX at 2700 FPS
Achieving a muzzle velocity of 2700 FPS with a 178gr ELDX bullet in a .308 Winchester is ambitious but possible. However, it will likely require a combination of optimal barrel length, a fast burning powder, and careful load development.
Here's a general approach to finding suitable load data:
* Consult Reliable Reloading Manuals:
* Refer to reputable reloading manuals like those from Hornady, Sierra, Hodgdon, or Lyman.
* Look for data specifically for the .308 Winchester cartridge and the 178gr ELDX bullet.
* While these manuals won't likely have data for exactly 2700 FPS, they will provide a starting point.
* Consider Powder Selection:
* A fast-burning powder is typically needed for higher velocities.
* Powders like Varget, Reloder 15, or H4350 are often used for .308 Winchester and might be suitable for your goal.
* Experiment with different powders to find the best performer for your rifle.
* Start Low, Work Up Gradually:
* Begin with a load significantly below the maximum listed in the reloading manual.
* Increase the powder charge in small increments, testing each load for accuracy and pressure signs.
* Use a chronograph to measure velocity and ensure you're within safe pressure limits.
* Barrel Length and Twist Rate:
* A longer barrel generally yields higher velocities.
* The twist rate of your barrel should be suitable for stabilizing the 178gr ELDX bullet.
* Other Factors:
* Primer type, brass quality, and seating depth can also affect velocity and accuracy.
* Experiment with different combinations to find the optimal setup.
Additional Tips
* Use a reloading scale: Ensure precise powder measurements.
* Check for pressure signs: Watch for signs of excessive pressure, such as flattened primers, excessive case head expansion, or hard bolt lift.
* Wear safety gear: Always wear eye and ear protection when reloading and shooting.
* Consider using a load development service: Some companies offer load development services for a fee.
Remember: Reloading is a learning process. Be patient, meticulous, and prioritize safety.
