The core of this article focuses on the ballistic chart, a roadmap that illustrates how the bullet performs across the landscape. This data, though presented numerically, is far from cold facts. It’s a tool that empowers hunters to make confident shots, ensuring a humane hunt and maximizing their chances of success.
The Legacy of the Core-Lokt
The Remington Core-Lokt has earned a reputation as one of the most reliable and effective hunting bullets available. Its history dates back to the early years of the twentieth century, when Remington engineers sought a bullet that could provide consistent performance and controlled expansion. The innovation was in the core design: a lead core mechanically locked to the copper jacket. This bonding process provided a consistent expansion, even at varying velocities and impact energies.
The Core-Lokt design prioritizes reliable expansion. This means that the bullet is designed to mushroom outwards upon impact, increasing its diameter and creating a larger wound channel. This expansion is carefully engineered to deliver the right balance of penetration and energy transfer, resulting in a more effective and humane kill. The controlled expansion helps the bullet retain its weight and minimize the loss of energy as it passes through the target.
Crafting the Perfect Shot: Design and Build
The Remington Core-Lokt bullet is built around a lead core encased in a copper jacket. The jacket is precisely designed and drawn to create the bullet’s specific shape and controlled expansion characteristics. The crucial element is the mechanical locking process between the lead core and the copper jacket. This prevents the core from separating from the jacket upon impact, ensuring maximum weight retention and penetration.
The tip of the bullet is typically designed for consistent expansion. This can be a soft point or a hollow point, which helps initiate the expansion process upon impact. The shape of the bullet and the way the jacket is drawn will determine the ballistic coefficient, a factor that greatly influences how well the bullet resists air drag and maintains its velocity over long distances.
The 150-grain weight is a versatile choice for the .30-06 Springfield. It’s heavy enough to deliver sufficient energy for taking down medium to large game, but it still maintains a relatively flat trajectory compared to heavier bullets. This flat trajectory contributes to less holdover at longer distances. It is a popular option for hunting deer, elk, black bear, and other similar-sized game animals.
Decoding the Ballistics: Charting the Course
To understand the performance of the Remington Core-Lokt 150-grain .30-06, we must examine the ballistic chart. Remember that the specific figures will vary slightly depending on the load. However, this data illustrates the general performance characteristics you can expect. This data is typically collected under standardized conditions.
This bullet is typically fired from a rifle with a standard barrel length. The data provided below demonstrates how a Remington Core-Lokt 150-grain bullet might perform.
- Muzzle Velocity: The starting point: approximately 2910 feet per second (fps). This is a crucial number as it sets the stage for everything that follows.
- Ballistic Coefficient: This is a number that represents the bullet’s ability to overcome air resistance. The Remington Core-Lokt 150-grain bullet typically has a ballistic coefficient around 0.402. A higher BC means the bullet will retain its velocity better over distance.
- Bullet Drop:
- At one hundred yards, the bullet’s drop is minimal, typically around 0.5 inches when the scope is zeroed for this distance.
- At two hundred yards, you will notice a drop of around 2.5 inches, which illustrates how gravity begins to pull the bullet down.
- At three hundred yards, the bullet drop increases to roughly 7 inches.
- At four hundred yards, the drop continues, reaching approximately 15 inches.
- At five hundred yards, the bullet drops to around 27 inches.
- Velocity:
- At one hundred yards, the velocity will likely be around 2650 fps.
- At two hundred yards, the velocity drops to approximately 2415 fps.
- At three hundred yards, the velocity further decreases, falling to about 2190 fps.
- At four hundred yards, the velocity is about 1980 fps.
- At five hundred yards, the velocity will be around 1780 fps.
- Energy:
- At one hundred yards, the bullet’s energy is still significant, about 2330 foot-pounds.
- At two hundred yards, the energy drops to approximately 1940 foot-pounds.
- At three hundred yards, the energy decreases to around 1600 foot-pounds.
- At four hundred yards, the energy drops to about 1300 foot-pounds.
- At five hundred yards, the energy retained is around 1050 foot-pounds.
- Wind Drift: (This value may vary depending on the wind speed)
- In a ten mile per hour crosswind, at three hundred yards, the drift could be around 5 inches.

Unpacking the Numbers: The Meaning Behind the Data
The ballistic chart provides a wealth of information, and the key is understanding how to interpret it. The trajectory data shows how much the bullet will drop over distance. The velocity data helps determine how much energy the bullet will deliver at impact.
For hunting applications, the energy retained is crucial. You want to ensure that the bullet has enough energy to effectively penetrate the animal and create a lethal wound channel. The 150-grain Core-Lokt, with its retained energy at ranges of up to 300 yards, is a viable option for most big game. However, for longer shots, you’ll have to account for the increased drop, the reduced velocity and the loss of energy. The effective range for a clean kill depends heavily on the animal you are hunting and your shooting skills.
The wind drift data demonstrates how much the wind will influence the bullet’s path. This becomes more significant as the range increases.
Environmental and Practical Considerations
Factors in the Equation: Environmental Influence
The ballistic chart is a starting point, but several external factors influence a bullet’s flight. Air density plays a significant role. Altitude, temperature, and humidity all affect air density. At higher altitudes and lower temperatures, the air becomes denser, which results in a bullet dropping more. The wind also introduces an unpredictable element, influencing the bullet’s path.
The type of rifle, the specific load of ammunition, and even the quality of the scope can all influence a bullet’s flight. Your zeroing technique is critical. Zeroing is the process of calibrating your scope so that it aligns with the bullet’s trajectory at a specific range.
Ready for the Hunt: Practical Tips
Before you head out on your hunt, familiarize yourself with your rifle and the specific ammunition you are using. Practice at the range at different distances, noting the bullet drop at each one. Use a ballistic calculator or app to account for environmental variables, or adjust your scope to accommodate the bullet’s arc.
When in the field, always consider the wind. If you have any doubt about making an ethical shot, don’t take it. Shot placement is key for a quick, humane kill. Understand the animal you are hunting, its size, and its reaction to shots.
Consider the capabilities of the Remington Core-Lokt 150-grain .30-06 bullet. It is most effective on medium-sized game.
