  2. Brass Preparation

    • Use consistent brass (Lake City 2019 brass in this case). Ensure all brass is cleaned, sized, trimmed, chamfered, deburred, and primed.

  3. Ammo Loading

    • Conduct a ladder test with various powder charges (23, 23.5, 24, 24.5, and 25 grains of H335 powder with 55-grain Hornady full metal jacket bullets).
    • Precisely measure and dispense powder charges using a digital scale and a charge master.
    • Seat bullets consistently, aiming for a consistent crimp depth.

  4. Testing and Data Collection

    • Have multiple shooters test each load to account for variations in shooting technique.
    • Shoot five groups for each powder charge at a suitable distance (in this case, 300-400 yards).

Tips

  • Even if a load has worked well in the past, periodically revisit it to check for accuracy and consistency.
  • Use a consistent batch of powder and brass for the most accurate results.
  • Pay close attention to details like bullet seating depth for consistent results.
  • Test loads under various conditions to ensure reliability.

Common Mistakes to Avoid

1. Inconsistent Powder Charges

Reason: Variations in powder weight lead to inconsistent bullet velocities and therefore, poor accuracy. This can be caused by inaccurate powder dispensing or inconsistent case volume.
Solution: Invest in a precise powder scale and ensure consistent case preparation, including uniform sizing and trimming.

2. Improper Bullet Seating Depth

Reason: Incorrect bullet seating depth can alter the bullet's jump to the rifling, impacting accuracy and potentially leading to pressure issues.
Solution: Use a bullet comparator and seating die to consistently seat bullets to the optimal depth for your specific load.

3. Neglecting Neck Tension

Reason: Insufficient or excessive neck tension can cause bullets to shift during firing, leading to inconsistent accuracy.
Solution: Ensure proper neck tension by carefully adjusting your sizing die and using a case neck turning tool for extreme accuracy.

FAQs

What's the most important factor affecting .223 reloading accuracy?
Consistency is key! Maintaining consistent bullet seating depth, powder charge, and overall case preparation is far more critical than chasing tiny variations in components. Even small inconsistencies can significantly impact accuracy.
