And when it comes to a platform that blends accuracy, affordability, and widespread availability, the .308 Winchester cartridge stands out as a compelling choice. This guide dives deep into the world of “Long Range Shooting 308,” providing everything you need to embark on or refine your journey into the realm of precision shooting.
The .308 Winchester, also known as the 7.62x51mm NATO, isn’t just a round; it’s a legend. Born from military necessity and refined for civilian use, its history is interwoven with the evolution of modern firearms. The genesis of the .308 Winchester lies in the quest for a shorter, more efficient cartridge than the venerable .30-06 Springfield. Developed in the early 1950s, it quickly gained popularity, quickly proving its worth.
The appeal of the .308 for long range applications is multifaceted. First and foremost, it boasts a reputation for inherent accuracy. The carefully designed case and projectile configurations often translate to tight groupings downrange. This is a critical advantage when aiming for targets hundreds of yards away.
Another significant advantage is the readily available nature of ammunition and reloading components. Unlike some more specialized cartridges, .308 Winchester ammunition can be found in virtually any gun store or online retailer. This means more time shooting and less time hunting for scarce supplies. Component availability also makes it a favorite for reloaders, who can fine-tune their loads to maximize performance.
Furthermore, the .308, compared to larger calibers like the .300 Winchester Magnum, offers a relatively moderate recoil. This is a significant factor for comfort and follow-up shots, allowing shooters to maintain better control and observe their shots more effectively. Less recoil also makes the .308 a more approachable round for shooters of all sizes and experience levels.
Finally, the .308 provides a good balance between cost and performance. Ammunition and components are generally less expensive than those for magnum cartridges, making it an excellent choice for those on a budget or for those who want to spend more time practicing without breaking the bank.
Disadvantages and Alternatives
Of course, no cartridge is perfect. The .308 has its limitations in the world of long range shooting. One key drawback is its trajectory compared to faster, flatter-shooting rounds like the 6.5 Creedmoor. The .308’s bullets tend to drop more over long distances, which requires more precise elevation adjustments.
Additionally, .308 projectiles are somewhat more susceptible to wind drift than heavier, higher ballistic coefficient bullets. This means wind calls become even more crucial at extended ranges.
Lastly, while the .308 is effective at long ranges, its optimal performance generally falls within a certain range. While capable of reaching out much further, its effectiveness may diminish compared to cartridges specifically designed for extreme long-range engagements.
Essential Gear for Long Range .308 Success
Rifle and Optics
The right equipment is essential for consistently hitting your target in the realm of long range shooting. The .308 Winchester, like any precision tool, demands careful selection and attention to detail.
Let’s start with the rifle. A bolt-action rifle is the preferred choice for long range shooting. The robust design and inherent accuracy potential of bolt-action platforms make them ideal for the precise nature of the sport. Consider barrel length and profile. Heavier barrels, often referred to as target or varmint barrels, are less prone to heat-related issues and generally provide enhanced accuracy over longer strings of fire. The stock is another important factor. Adjustable stocks are highly recommended; they allow the shooter to tailor the rifle’s ergonomics to their specific body type and shooting position, leading to improved comfort and consistency. Chassis systems, which are becoming increasingly popular, provide a rigid platform for the action and are often highly adjustable.
Next comes optics. The scope is arguably the most critical piece of equipment. Magnification is a primary consideration. While it’s tempting to go for the highest magnification possible, a range of power is generally the best choice. Many long range shooters find a scope with a magnification range of, say, 5-25x or 6-24x ideal. Choose features like First Focal Plane (FFP) or Second Focal Plane (SFP), along with mil-based or MOA (Minute of Angle) based reticles. The reticle itself should be designed for long-range use, with features like windage markings and elevation holdovers. Proper scope mounting is also crucial. High-quality rings and bases ensure the scope is securely attached to the rifle, and that the reticle is properly aligned.
Ammunition and Support Gear
Choosing the correct ammunition is vital. Bullet weight plays a critical role. .308 Winchester bullets range in weight, but for long range shooting, you’ll typically want to opt for bullets in the 168-grain to 180-grain range. Heavier bullets typically offer better ballistic coefficients, helping them retain velocity and resist wind drift at longer distances. Bullet type, such as match grade or hollow point, also matters. Match-grade bullets are designed for maximum accuracy, while hollow point bullets offer controlled expansion upon impact, which can be important for hunting.
Support equipment is crucial to the success of any “Long Range Shooting 308” setup. A sturdy bipod provides a stable platform for shooting from a prone position. A spotting scope or binoculars allows the shooter to observe the impact points of their shots and make corrections as needed. A laser rangefinder is invaluable for accurately measuring the distance to the target. This is fundamental for making accurate elevation adjustments. Finally, a ballistic calculator, either a handheld device or a smartphone app, is a must-have. It uses data like muzzle velocity, ballistic coefficient, and environmental factors to predict bullet trajectory. A wind meter, or even the use of wind flags on the range, will help determine the precise effects of wind on the bullet’s flight.
Ballistics and the Art of Long Range Calculation
Understanding Ballistic Concepts
Understanding ballistics is not optional, but essential. The .308 Winchester’s performance at long range hinges on understanding how its bullets behave in flight.
Ballistic Coefficient (BC) is a crucial concept. The BC is a number that represents a bullet’s ability to overcome air resistance. Higher BCs indicate greater efficiency in retaining velocity over distance. When choosing bullets, pay close attention to their BC ratings. The higher the BC, the better the bullet will perform in resisting wind drift and retaining velocity at longer ranges.
Calculating bullet trajectory is where a ballistic calculator comes into play. Input the bullet’s BC, muzzle velocity, along with environmental data like temperature, altitude, and humidity, into the calculator. The calculator will provide data on bullet drop, wind drift, and the necessary adjustments to make in your scope to compensate for these factors.
Wind, Elevation and Environment
Wind drift is a major factor for long range shooting. The wind pushes the bullet sideways, and the amount of drift increases with distance. Learning to estimate wind speed and direction is a crucial skill, and even more so when doing “Long Range Shooting 308.” Using a wind meter or wind flags, and observing the movement of natural features such as grass or trees can help inform your wind calls. The ballistic calculator will show how the wind affects the bullet. Then, learn to compensate for the wind by adjusting your scope for windage.
“Doping” your scope, or making precise adjustments to elevation and windage, is fundamental to accurate long range shooting. A good scope will have adjustments in units, such as MOA or mils. Learn how to use these adjustments and consistently apply them to make accurate shots.
Environmental factors also play a critical role. Temperature, altitude, and humidity can all influence bullet trajectory. The higher the altitude, the less dense the air, and the less bullet drop. Temperature affects the bullet’s velocity. Humidity can affect the air density. A good ballistic calculator can account for all these factors.
Finally, be aware of when your bullet transitions to a subsonic velocity. This occurs when the bullet slows to below the speed of sound. When a .308 Winchester bullet goes subsonic, it becomes more unstable. Knowing when this is happening, and how to account for it in your calculations, is important for accuracy.
Shooting Techniques: The Path to Precision
Fundamentals of Marksmanship
Having the right gear and understanding ballistics is only part of the equation. Mastering shooting techniques is key to consistently hitting your target.
First, and foremost, focus on the fundamentals of marksmanship. Achieve a consistent, comfortable stance. The prone position, with your body flat on the ground, is a stable platform for long-range shooting. Maintain a consistent cheek weld on the stock, which helps you maintain the same eye relief from the scope each time. Control your breathing. Take slow, deep breaths and exhale slowly, pausing just before breaking the shot. Trigger control is paramount. Squeeze the trigger smoothly and steadily, without jerking, to avoid disturbing the rifle. Follow through after the shot. Stay on the target and maintain your position until the bullet hits the target.
Zeroing, Wind, and Positions
Zeroing your rifle is an essential early step. Choose a known distance, typically 100 or 200 yards, and adjust your scope so that your shots consistently hit the point of aim. Once your zero is established, you can use the ballistic calculator and the appropriate adjustments on your scope to hit targets at longer ranges.
Reading the wind is a continuous process. Observe wind flags, note the wind direction, and estimate the wind speed. Use this information, along with the data from your ballistic calculator, to make accurate windage adjustments on your scope. Remember that wind changes. Wind speeds can fluctuate, and shifts in direction can dramatically affect the bullet’s flight.
Adjusting for elevation involves using the elevation dial on your scope to compensate for bullet drop at different distances. This is where the ballistic calculator comes into play; it gives you the necessary elevation adjustments for various ranges.
Positional shooting skills expand your shooting capabilities. While the prone position provides the most stable platform, practice shooting from other positions, such as seated or kneeling. This helps you adapt to various shooting scenarios.
Range estimation is another vital skill. While a laser rangefinder is ideal, you can learn to estimate ranges using reticle features. Learning how to judge distances using various methods helps increase your shooting efficiency.
Dry fire practice is invaluable. Practice your shooting fundamentals at home, without live ammunition. This allows you to improve your technique, develop muscle memory, and develop a consistent routine.
Practical Application and Range Considerations
Range Selection and Safety
Practice is crucial, and putting it all together on the range is where it happens.
When choosing a shooting range, look for one that offers the distances you need, with sufficient space and safety. Consider the prevailing conditions, such as wind. Observe the range’s safety rules and regulations at all times.
Safety must always be your number one priority. Wear appropriate eye and ear protection. Always treat every firearm as if it were loaded. Be mindful of your surroundings and the direction of fire.
Building a Data Book and Consistency
Build a data book to record your observations. Track your ammunition, load data, and the environmental conditions at the range. Take notes on your adjustments, the impact of the wind, and the performance of your loads.
Be prepared to deal with environmental factors. Mirage, created by heat waves rising from the ground, can distort your vision. Changing wind conditions demand constant observation and adjustment.
Consistency is key. Strive to use a repeatable process with all of the steps involved in “Long Range Shooting 308” and repeat this process every time you shoot. The more you practice, the more consistent your results will be.
Reloading the .308: Customizing for Superior Performance (Optional)
Reloading provides the ultimate level of control over your ammunition. Reloading enables you to fine-tune your loads, experimenting with different powders, primers, and bullet weights to optimize your rifle’s performance. Reloading safely involves a good set of scales, calipers, and measuring instruments, and following all safety protocols. Finding the right powder, the right charge weight for your rifle, and the right overall cartridge length are all part of developing a custom load. Carefully monitor the cases for signs of pressure, and always stay within published reloading data.
