A Remington Core-Lokt Trajectory Chart is an essential ballistic reference for hunters using one of the most trusted and widely available hunting bullets in history. Known for its “deadly mushroom” terminal performance, the Core-Lokt bullet is available in a vast array of centerfire rifle calibers. Because this bullet design is optimized for controlled expansion rather than extreme long-range aerodynamic efficiency, understanding its trajectory is critical for hunters who prefer traditional, proven ammunition. This guide details the flight path for several representative Core-Lokt factory loads, allowing you to accurately calculate holdover and ensure precise shot placement in the field.

Note: Data represents average performance for factory loads. Always check the specific ballistics printed on the ammunition box for your exact caliber and bullet weight.
To use this chart, locate the row corresponding to your rifle’s caliber and bullet weight. With a 200 yard zero, the values listed under each yardage represent the vertical drop in inches from your point of aim. For example, if you are hunting with the 30-06 Sprg 150 grain load, you can expect a drop of 8.5 inches at 300 yards. Always remember that actual performance can vary based on your rifle’s barrel length and local environmental conditions.
Understanding The Remington Core-Lokt Trajectory Chart
The Core-Lokt design is focused on reliability and terminal performance rather than achieving the highest ballistic coefficient. This means its trajectory is classic and predictable, making it a favorite for hunters who hunt at standard distances.
Trajectory Analysis
The trajectory of the Core-Lokt is heavily influenced by its bullet profile, which typically features a soft-point design that is very effective at close-to-medium ranges. The 300 Win Mag 180 grain load provides the flattest path among the examples above, dropping only 33.8 inches at 500 yards. In contrast, the 30-06 Sprg 180 grain load drops 40.1 inches at the same distance, reflecting the difference in velocity between the two cartridges.
Velocity Analysis
Muzzle velocity is the primary factor that flattens the Core-Lokt’s flight path. High-velocity cartridges like the 243 Win and 300 Win Mag minimize the bullet’s time in the air, which directly reduces the vertical drop. If you are shooting a lower-velocity caliber, it is essential to be more conservative with your maximum engagement distance.
Ballistic Coefficient Analysis
The Core-Lokt bullet is not designed to be a high-BC match projectile, which means it will lose velocity faster than specialized long-range bullets. The higher BC values in our chart (e.g., 0.383 for the 180 grain loads) indicate bullets that hold their speed better at distance. Always keep this in mind if you are taking shots past 300 yards, as the bullet’s drop will begin to accelerate more rapidly than a high-BC match bullet.
Best Factory Loads Based On The Chart
For general-purpose big game hunting in various environments, the 30-06 Sprg 150 grain load is the gold standard for its balance of trajectory and energy. If your hunting requires shots at slightly longer distances, the 300 Win Mag 180 grain load provides the flattest path and best retained energy. For lighter game or where recoil management is a priority, the 243 Win 100 grain load offers very manageable drop metrics.
Factors That Affect Core-Lokt Trajectory
Barrel Length
Factory ballistics are measured in standardized test barrels. If your hunting rifle has a shorter barrel, you will likely experience lower muzzle velocities, which will result in more bullet drop than the values in this chart.
Bullet Profile
The exposed lead tip of the Core-Lokt bullet is excellent for expansion, but it creates more drag than polymer-tipped bullets. This is a deliberate design choice that prioritizes terminal performance over extreme long-range aerodynamics.
Temperature and Altitude
Like all hunting rounds, Core-Lokt performance is affected by the environment. Denser, cold air will cause the bullet to drop faster, while thinner air at high altitudes will allow it to fly flatter.
Frequently Asked Questions
Is the Remington Core-Lokt accurate?
Yes, it is known for being very accurate for hunting purposes, often producing groups that are more than sufficient for harvesting big game at standard ranges.
Is the Core-Lokt good for long-range hunting?
It is perfectly capable for shots out to 300 yards, but it is not optimized for extreme long-range competition or hunting beyond that distance compared to high-BC match bullets.
Why is the trajectory of my Core-Lokt different from match ammo?
Core-Lokt is designed for controlled expansion on game, not aerodynamic efficiency. Match ammunition usually features higher BC bullets that retain velocity better.
What is the best zero distance for Core-Lokt?
A 200 yard zero is the recommended standard, allowing for a point-blank shooting experience on most big game at reasonable distances.
Can I hunt deer with Core-Lokt?
Absolutely, it is one of the most popular and effective deer hunting bullets ever made.
What if my caliber isn’t on this chart?
Check the side of your ammunition box, as Remington provides a detailed trajectory table for every specific Core-Lokt product they manufacture.
