Understanding Ballistics Basics
To fully appreciate the performance of the Remington Core Lokt 308 180 Grain bullet, it’s essential to understand the basic principles of ballistics. This section will clarify key terms and how they impact the bullet’s path and effectiveness.
Let’s start with Muzzle Velocity (MV). This is the speed at which the bullet exits the barrel of the rifle. Measured in feet per second (FPS) or meters per second (MPS), muzzle velocity is a critical factor as it sets the initial speed for the bullet’s journey. A higher muzzle velocity generally results in a flatter trajectory and a longer effective range, all other things being equal.
Next, we have Muzzle Energy (ME). Muzzle energy, often expressed in foot-pounds (ft-lbs) or joules (J), represents the kinetic energy of the bullet at the moment it leaves the muzzle. It’s a measure of the bullet’s potential destructive power.
The Ballistic Coefficient (BC) is a number that indicates a bullet’s ability to overcome air resistance. A higher BC means the bullet is more aerodynamic and will retain its velocity better over distance. Wind affects low BC bullets far more than high BC bullets. This is a crucial factor for long-range accuracy and helps minimize bullet drop.
Trajectory is the path a bullet takes through the air. Due to gravity, a bullet doesn’t travel in a perfectly straight line. Instead, it follows a curved path, constantly dropping towards the ground. This curved path is called bullet drop, and the amount of bullet drop increases with distance.
Wind Drift is the sideways movement of a bullet caused by wind. The amount of wind drift is influenced by the wind speed, wind direction, and the bullet’s BC. This is especially important when shooting at longer ranges, and careful wind reading is crucial for accuracy.
Understanding Sight Height is another crucial element to achieving accurate shots. The height of the scope or sight above the bore axis affects the bullet’s trajectory. This, too, must be taken into account when zeroing your rifle.
These ballistic factors work together to determine how a bullet performs. The shooter’s knowledge and understanding of each element contribute to the accuracy of the shot.
Remington Core-Lokt 308 180 Grain Bullet: Details
Let’s now explore the specifics of the Remington Core-Lokt 308 180 Grain bullet. This bullet’s construction and design contribute to its reputation for controlled expansion and effective terminal performance.
The Core-Lokt design is centered on a mechanical lock between the bullet’s lead core and its copper jacket. This “locking” mechanism is what gives Core-Lokt bullets their namesake. This design, involving a jacket mechanically fastened to the lead core, delivers a consistently high degree of weight retention, an important factor in ensuring deep penetration. Upon impact, the soft point or tipped design encourages the bullet to expand, mushrooming outward to increase its diameter and transfer energy to the target. The controlled expansion, combined with deep penetration, makes it an excellent option for hunting medium to large game.
The 180-grain weight is often regarded as a versatile option for the .308 Winchester. The 180-grain Core-Lokt bullet strikes a balance between trajectory, recoil, and energy transfer, and is suitable for several hunting applications. The heavier 180-grain bullets tend to retain their energy better over long distances and may be less affected by wind than lighter bullets, too.
Depending on the specific product, the bullet type for the Remington Core-Lokt 180-grain in .308 typically features a soft point design, such as a soft point (SP) or a pointed soft point (PSP).
Remington Core Lokt 308 180 Grain Ballistics Chart
Here is the ballistics chart for the Remington Core Lokt 308 180 Grain bullet, offering an overview of its performance. The chart is based on the manufacturer’s data under standard atmospheric conditions. Remember that real-world results can vary based on environmental conditions, rifle specifics, and other factors.
Ballistics Chart
- Bullet: Remington Core-Lokt 308 180 Grain

Range (Yards) | Velocity (FPS) | Energy (ft-lbs) | Bullet Drop (inches) | Wind Drift (inches) (10 mph crosswind) |
---|---|---|---|---|
0 | 2700 | 2913 | 0 | 0 |
50 | 2591 | 2677 | -0.8 | 0.6 |

How to Use the Ballistics Chart
The chart provides data on velocity, energy, bullet drop, and wind drift across several yardage intervals. To use it effectively, first, identify the distance to your target. Then, look at the corresponding values for bullet drop and wind drift at that range. For example, if your target is at 300 yards, your bullet will drop approximately 26.4 inches and, with a 10 mph crosswind, drift about 4.8 inches. This data will provide you with the necessary information to compensate for bullet drop and wind. Remember to adjust for any variations in shooting conditions.
The conditions used to generate the ballistics data typically involve standard atmospheric conditions at sea level. This includes a temperature of 59°F (15°C) and a barometric pressure of 29.53 inches of mercury (1013.25 hPa). The chart’s zero distance is 100 yards.
Influencing Factors on Ballistics
Several variables can influence the Remington Core Lokt 308 180 Grain bullet’s performance. Understanding these factors will help you adapt to different shooting conditions and maximize accuracy.
Weather conditions are a significant factor. Temperature plays a role as higher temperatures tend to increase muzzle velocity slightly. Altitude affects both air density and bullet drop; at higher elevations, bullets travel farther due to the reduced air resistance. Though less significant, humidity can also play a very small role in ballistics.
Properly sighting in your rifle is fundamental to shooting accurately. Ensuring that your rifle is properly sighted at your desired zero range is an essential step for ensuring accurate shot placement. The zero distance directly influences the bullet’s trajectory, so it’s important to choose a zero range that suits your typical shooting distances.
The barrel twist rate, expressed as a ratio (e.g., 1:10, meaning one full rotation in 10 inches), is another important factor. The twist rate determines the stability of the bullet in flight. The .308 Winchester typically utilizes a 1:10 or 1:12 twist rate which is generally a good fit for 180-grain bullets.
Even with the same ammunition, slight variations can occur. Variations in manufacturing can result in small differences in bullet weight, diameter, and even the consistency of the powder load.
Practical Uses of the Bullet
Let’s discuss the appropriate scenarios for the Remington Core-Lokt 308 180 Grain bullet.
For hunting purposes, the Remington Core Lokt 308 180 Grain bullet is often selected for medium to large game such as deer, elk, and black bear. It provides sufficient penetration and energy transfer to effectively take down these animals, provided the shot placement is accurate.
For target shooting, this bullet can be used for practice and informal shooting. The design might be suitable for paper targets at moderate distances.
