Understanding the Fundamentals: Why Sighting In Matters
The sharp crack of a well-placed shot, the satisfying impact on the target – that’s the ultimate goal of any shooter. Whether you’re a seasoned hunter aiming for a clean kill or a dedicated target shooter striving for pinpoint accuracy, the ability to precisely align your rifle with your chosen target is paramount. But what happens when your shots consistently land astray? The answer often lies in the critical process of sighting in your rifle. This guide is designed to provide you with a comprehensive understanding of sighting in a .308 rifle, equipping you with the knowledge and techniques necessary to achieve the accuracy you deserve. The .308 Winchester, a cartridge celebrated for its versatility and effectiveness, deserves to be wielded with precision. This article explores the essential steps to make that a reality.
Sighting in a rifle is, at its core, the process of adjusting your rifle’s sights – whether they be iron sights or a scope – to ensure that your bullets strike the intended point on the target at a specific distance. It’s the crucial link between your aiming and the projectile’s actual path. Proper sighting in is not just about hitting the bullseye; it’s the very foundation of accurate shooting, critical for both hunting and target practice.
Consider the ethical implications for hunters. A poorly sighted rifle can lead to a wounded animal and a prolonged, agonizing death. Conversely, a properly sighted rifle promotes clean, humane kills, aligning with ethical hunting practices.
Furthermore, it’s a cornerstone of safety. Imagine aiming at a target only to have your bullets deviate far from the intended path. This poses a considerable risk to yourself and others on the range or, worse, in the field. A well-sighted rifle offers a measure of control over where the bullets go, enhancing safety and minimizing the risk of unintended consequences.
Therefore, mastering the art of sighting in is not just a technique; it’s a responsibility. Before we delve into the mechanics, let’s understand the concept of zeroing. Zeroing is the term used to establish the point of impact (POI) of your bullets at a specific distance. For example, when you “zero” your rifle at a hundred yards, you’re adjusting your sights so your bullets impact the target at that distance. That chosen distance is often referred to as your “zero.” The distance you choose will impact the shooting you plan to do. A hunter might zero at two hundred yards for a longer engagement and less holdover to get to the target. A target shooter may choose a shorter distance to gain precision.
Necessary Gear and Preparation: Setting the Stage for Success
Before you even think about pulling the trigger, you’ll need the proper equipment. The quality of your gear directly impacts your success in sighting in a .308 rifle.
The first essential is, of course, the rifle and its sighting system. This includes the rifle chambered in .308 Winchester. The .308 is a very versatile cartridge, which requires a quality optic. The quality of the optic will affect the longetivity of your zero. Choose a quality scope suitable for your intended use, such as variable-power scopes. These offer adjustable magnification levels for different distances and target types. Ensure the scope is properly mounted on the rifle. Poorly mounted scopes can shift zero and disrupt your ability to sight it in correctly. Make sure the rings are tightened to the manufacturer’s specifications.
Next, the ammunition. Consistency is crucial. Start by selecting a high-quality ammunition that is appropriate for your .308. Using consistent ammunition (same brand, same bullet weight) is key to reliable results. Note that the bullet weight influences the POI. Experiment with different ammunition types down the line to see what shoots best in your rifle.
A suitable target is also essential. A well-defined target allows you to clearly see where your shots are impacting. Use targets designed specifically for sighting in, with clear aiming points, usually bullseye or grid patterns. The clearer the aiming point, the easier it will be to make accurate adjustments.
A stable shooting platform is another vital piece of equipment. This is where a shooting rest comes in. A stable rest minimizes movement during your shots, allowing you to focus on the fundamentals of shooting. These can range from a simple sandbag rest to a sophisticated bipod or tripod system. If you’re at a bench, use it. If you’re hunting in the field, get as solid a rest as possible.
Finally, ensure you have essential safety equipment, including eye and ear protection. Safety should always be the priority. Make sure you and your eyes and ears are protected.
The Sighting-In Process: A Step-by-Step Guide
With the necessary equipment assembled, you’re now ready to begin the sighting-in process. Remember, safety always comes first.
Begin by thoroughly reviewing and adhering to all range safety rules. This includes properly handling your firearm, ensuring the muzzle is always pointed in a safe direction, and keeping your finger off the trigger until you’re ready to fire.
Carefully inspect your rifle. Make sure the action is clear. Before anything else, verify that your firearm is unloaded. It is easy to overlook this step and accidentally have a loaded weapon. It is important to make sure you are safe.
At this stage, a bore sighting is highly recommended. Bore sighting involves looking through the barrel of the rifle and aligning it with a target. This gets your shots “on paper” much faster, saving you time and ammunition. This is a useful tool.
Now, set up your target at your chosen zeroing distance. Choose a distance suitable for your intended use of the .308. Place the target at, say, one hundred yards for hunting or target shooting.
With the target in place, it’s time to take your first shots. Begin by firing a small group of shots – typically three to five. This is your initial group, which will help determine where the bullets are impacting the target and allow you to make adjustments. This is a trial run.
After firing, examine your shot group. Determine the average point of impact of your bullets on the target. Is it high or low? Left or right? Note the exact location of the group.
This is where adjustments come into play. Scopes are adjusted using the turrets. Scopes use two turrets: one for windage (left/right adjustments) and one for elevation (up/down adjustments). Most scopes have clicks, each click representing a specific unit of adjustment (MOA or MIL) at one hundred yards. The number of clicks per unit of adjustment should be clearly marked on the turret. Make sure to understand how the adjustments work on your specific scope. Adjust the scope according to where you need to move your point of impact. If your group is consistently low and left, you will want to move the elevation up (clockwise) and the windage right (clockwise).
After making an adjustment, shoot another group of shots. Reassess the impact and adjust your scope again if needed. The goal is to bring your shots into the bullseye. Don’t over-adjust.
Fine-tuning is where patience becomes a virtue. Making small, incremental adjustments and shooting small groups will refine your zero. Avoid making large adjustments. Start with small adjustments and work your way to the target.
Once your shots consistently strike the target at your chosen distance, you’ve achieved your zero. Confirm your zero by firing one last group. If the shots are in the desired place, then you know you’ve done it. If needed, make final adjustments to make it perfect.
Further Practice and Maintenance: Ensuring Sustained Accuracy
Sighting in your .308 rifle is a great first step, but maintaining that zero and improving your shooting skills requires ongoing effort.
Regularly check your zero. A zero can shift over time for various reasons, including changes in ammunition, temperature fluctuations, or accidental bumps to your scope. Make it a habit to check your zero before each hunting season or shooting competition and periodically throughout the year. You should also re-check when you change ammo.
Practice at different ranges. Once you’ve achieved your zero, practice shooting at varying distances. This enhances your skills in judging bullet drop and wind drift.
Maintain your rifle and scope. Clean your rifle regularly, following the manufacturer’s instructions. Inspect your scope for any damage or loose components. Proper maintenance helps keep your rifle in good condition. Keeping your rifle in good shape is also a great way to improve your consistency and keep your zero.
Consider keeping a log of your shooting results. Document the date, ammunition used, weather conditions, and any adjustments made to your scope. This information will prove invaluable when you need to re-sight your rifle or troubleshoot any accuracy issues.
Common Pitfalls and Troubleshooting: Addressing Accuracy Problems
Even with the best techniques, issues can arise. Here’s how to address common problems:
Scope Issues: Check scope mounts and rings regularly, ensuring they are secure. Loose mounts can significantly shift your point of impact. If you suspect scope damage, try swapping with a known good scope to rule out any internal malfunctions.
Shooter Errors: Practice proper shooting form and trigger control. Ensure proper breath control, and avoid jerking the trigger.
Ammunition Issues: Always use quality ammunition and ensure it is consistent. Try different types of ammunition to find the one that shoots most accurately in your rifle.
