20" Gov't Profile: Improve Your Long-Range Shots

The 20" government profile barrel is a popular choice among AR-15 enthusiasts, particularly those focused on long-range shooting. Its length provides significant advantages in accuracy and velocity, making it a superior option compared to shorter barrels for precision work at extended distances. But simply owning a 20" government profile barrel isn't enough; understanding how to optimize its performance is key to consistently hitting your targets. This guide delves into the essential aspects of improving your long-range shots with a 20" government profile barrel.

Understanding the 20" Government Profile Barrel

The "government profile" refers to a specific barrel contour. It's heavier than many other profiles, offering several key benefits:

• Improved Accuracy: The added weight helps to dampen vibrations, leading to more consistent shot groups.
• Increased Barrel Life: The thicker barrel wall can better withstand the heat generated during rapid firing, extending its lifespan.
• Enhanced Velocity: The longer barrel allows for more complete powder burn, resulting in higher muzzle velocity and flatter trajectory. This is crucial for long-range accuracy.

However, the weight also presents a trade-off: it makes the rifle heavier and potentially less maneuverable. This is a consideration for some shooters, but the accuracy benefits generally outweigh the extra weight for long-range applications.

Key Factors for Improved Long-Range Accuracy

Beyond the barrel itself, several other factors critically impact your long-range shooting performance:

1. Ammunition Selection

Choosing the right ammunition is paramount. Factors to consider include:

• Bullet Weight: Heavier bullets generally have a flatter trajectory and are less affected by wind. Experiment to find the optimal weight for your specific rifle and intended range.
• Bullet Type: Match-grade ammunition, designed for superior accuracy, is highly recommended. Look for bullets with consistent construction and high ballistic coefficients (BC).
• Powder Charge: The proper powder charge ensures consistent and optimal velocity. Using factory ammunition ensures this is properly calibrated, but handloaders can fine-tune this for maximum precision.

2. Optics and Zeroing

Your scope and its mounting are vital. A high-quality scope with sufficient magnification is essential for long-range shooting. Proper zeroing is critical. Consider:

• Scope Magnification: Choose a scope with sufficient magnification to clearly see your target at extended ranges.
• Mounting System: Ensure a rigid and reliable mounting system to prevent scope shift and maintain zero.
• Zeroing Procedure: Use a methodical zeroing process, starting at shorter ranges and progressively working your way out to your maximum effective range.

3. Proper Shooting Technique

Even the best equipment is useless without proper technique. Fundamental shooting skills are paramount:

• Stance and Grip: Maintain a stable and consistent stance and grip to minimize movement and ensure repeatable shots.
• Breathing Control: Control your breathing to minimize movement during the shot.
• Trigger Control: Develop a smooth and consistent trigger pull to avoid disturbing the shot.
• Follow Through: Maintain your sight picture and hold until after the shot to ensure accuracy.

4. Environmental Factors

External conditions significantly impact long-range accuracy.

• Wind: Wind is perhaps the biggest challenge in long-range shooting. Learn to read and compensate for wind.
• Temperature: Temperature affects both bullet velocity and trajectory.
• Humidity: Humidity can affect the trajectory of projectiles.

Practice and Refinement

Consistent practice is vital to improve your long-range shooting skills. Regular trips to the range, focusing on the fundamentals and experimenting with different techniques and ammunition, are essential. Don't hesitate to seek guidance from experienced long-range shooters.

In Conclusion:

A 20" government profile barrel is a great foundation for long-range accuracy. However, optimizing its potential requires meticulous attention to detail across all aspects of the shooting process – from ammunition selection and optics to technique and environmental awareness. With consistent practice and a commitment to precision, you can significantly improve your long-range shooting performance.
