Why Choose Remington Core-Lokt Ammunition?
Remington Core-Lokt is not just ammunition; it's a testament to over 80 years of engineering excellence focused on delivering superior hunting performance. Here’s what sets it apart and why it remains a top choice for hunters worldwide:
- Proven Terminal Performance: The "Core-Lokt" name comes from its unique design: a lead core mechanically locked to a copper jacket. This design ensures controlled expansion upon impact, creating the classic "mushroom" shape that transfers maximum energy to the target while retaining enough bullet weight for deep penetration. This translates to devastating knockdown power and reliable, humane kills.
- Unmatched Reliability: Hunters cannot afford failure in the field. Core-Lokt ammunition is renowned for its consistent ignition, reliable cycling, and uniform ballistic performance, shot after shot. This consistency is crucial for making precise follow-up shots if needed and for overall confidence in your firearm system.
- Exceptional Accuracy: Precision is paramount in hunting. Core-Lokt bullets are manufactured to exacting standards, ensuring aerodynamic stability and uniform bullet weight, which contribute to tighter groups and predictable trajectories. For the hunter, this means greater confidence in shot placement, even at extended ranges.
- Versatility for Various Game: While the 140-grain weight is superb for medium-sized game like deer, the inherent power of the 7x57mm Mauser, combined with the robust Core-Lokt design, makes this ammunition effective for larger animals as well.
The Enduring Legacy of the 7x57mm Mauser Cartridge
The 7x57mm Mauser, also known as the .275 Rigby in the British Commonwealth, is a cartridge with a rich history dating back to 1892. Developed by Paul Mauser for the Spanish military, it quickly gained global recognition not only as a military round but also as an outstanding sporting cartridge. Its balanced characteristics—moderate recoil, flat trajectory, and excellent terminal performance—made it an immediate favorite among hunters and marksmen.
- A Hunter's Favorite: Famous hunters like W.D.M. Bell, who used it extensively for elephant hunting in Africa, solidified its reputation for power and effectiveness far beyond its apparent size. While perhaps not the first choice for elephants today, its historical performance underscores its capability on large game.
- Balanced Performance: The 7x57mm Mauser strikes an ideal balance between manageable recoil and sufficient power for a wide range of game. This makes it particularly appealing for shooters who desire effective hunting capabilities without the heavy recoil associated with larger magnum cartridges.
- Timeless Appeal: Despite the introduction of countless new cartridges, the 7x57mm Mauser has retained its popularity due to its inherent accuracy, efficiency, and classic appeal. It pairs perfectly with both vintage Mauser actions and modern rifles chambered for this historic cartridge.
Deconstructing the 140 Grain Core-Lokt Pointed Soft Point (PSPCL)
The specific 140-grain Core-Lokt Pointed Soft Point (PSPCL) bullet represents a pinnacle of hunting bullet design for this caliber. Let's break down its features:
- 140 Grain Weight: This bullet weight is often considered an ideal compromise for the 7x57mm Mauser. It offers a flatter trajectory than heavier bullets while retaining significant energy and momentum for deep penetration and decisive expansion on game. It's an excellent all-around choice for a variety of hunting scenarios.
- Pointed Soft Point (PSP): The pointed profile contributes to a higher ballistic coefficient, meaning the bullet retains velocity better over distance and is less affected by wind drift. The exposed lead tip ensures rapid and reliable expansion upon striking the target, initiating the "mushrooming" process that Core-Lokt is famous for.
- Core-Lokt Technology: The true magic is in the Core-Lokt's mechanical locking feature. This design prevents the lead core from separating from the copper jacket during expansion, ensuring that the bullet retains a high percentage of its original weight. Weight retention is critical for achieving deep penetration, which is vital for reaching vital organs in larger game and ensuring a quick, humane kill. The robust jacket and locked core also prevent premature fragmentation, ensuring controlled and effective energy transfer.
Real-World Use Cases: Where Does This Ammunition Shine?
Understanding how Remington Core-Lokt 7x57mm Mauser performs in the field helps illustrate its value to hunters.
- Deer Hunting: For species like whitetail, mule deer, and blacktail deer, the 140-grain PSPCL is an absolutely superb choice. Its consistent expansion and deep penetration ensure that even if the shot isn't perfectly placed, the bullet will still reach the vitals and deliver maximum stopping power. Many seasoned deer hunters consider this combination to be one of the most effective and ethical for typical deer hunting ranges.
- Antelope and Plains Game: The flat-shooting nature of the 7x57mm with the 140-grain PSPCL makes it suitable for open-country hunting where longer shots might be common. While its ballistic coefficient might not match modern VLD bullets, it performs admirably within typical hunting distances.
- Elk and Medium-Large Game: For elk, black bears, or even African plains game like kudu or wildebeest, the 7x57mm Mauser with the 140-grain Core-Lokt PSPCL is often considered the minimum effective caliber by experienced hunters. Its ability to penetrate deeply and deliver a wide wound channel makes it a viable option for these animals, provided shot placement is precise and ranges are kept within the cartridge's effective limits.
- General Purpose Hunting: If you own a 7x57mm Mauser rifle and are looking for a versatile, reliable round for a variety of North American game, this Remington Core-Lokt offering is an excellent all-around solution that simplifies ammunition choices.
Understanding Ballistics and Performance
While specific ballistic charts can vary slightly based on barrel length and atmospheric conditions, the general performance characteristics of the Remington 140-grain 7x57mm Mauser Core-Lokt PSPCL are well-established:
- Muzzle Velocity: Typically in the range of 2,660 to 2,750 feet per second (fps) from a standard length rifle barrel. This velocity ensures a relatively flat trajectory out to common hunting distances.
- Muzzle Energy: Generating approximately 2,195 to 2,360 foot-pounds (ft-lbs) of energy at the muzzle, this cartridge delivers more than enough power for ethical kills on medium to large game.
- Trajectory: With a 100-yard zero, the bullet typically rises a few inches at 150 yards before starting its descent. A 200-yard zero might see it drop around 6-8 inches at 300 yards, making holdover relatively manageable for hunters accustomed to their rifle and chosen zero.
- Downrange Performance: The Core-Lokt's ability to retain weight and expand reliably ensures that it maintains its effectiveness even at extended hunting ranges, delivering ample energy transfer for quick incapacitation.
Optimizing Your Hunting Success with Remington Core-Lokt
To get the most out of your Remington Core-Lokt 7x57mm Mauser ammunition, consider these practical tips:
- Know Your Rifle: Every rifle shoots differently. Before heading into the field, practice extensively with this specific ammunition in your rifle. Confirm your zero at various distances and understand how the bullet performs at different ranges.
- Practice Shot Placement: The best ammunition in the world can't compensate for poor shot placement. Focus on accurate, ethical shot placement to ensure a clean, humane harvest.
- Environmental Factors: Understand how wind, temperature, and elevation affect bullet trajectory. While the 7x57mm is forgiving, accounting for these factors will improve your long-range accuracy.

Frequently Asked Questions About 7x57mm Mauser Ammunition
Here are some common questions hunters and shooters ask when considering ammunition for their 7x57mm Mauser rifles:
- What is the best ammunition for deer hunting with a 7x57mm Mauser?
For deer hunting, the Remington 140-grain Core-Lokt PSPCL is an outstanding choice. Its balance of velocity, energy, and controlled expansion makes it highly effective for humane deer harvesting. Other popular options include 150-grain or 160-grain soft points, but the 140-grain offers a flatter trajectory for common hunting distances. - Is the 7x57mm Mauser powerful enough for elk?
Yes, the 7x57mm Mauser is capable of ethically taking elk, provided you use an appropriate bullet with good penetration and controlled expansion, like the 140-grain Core-Lokt PSPCL. Shot placement is critical, and it's generally recommended for experienced hunters who can make precise shots within reasonable ranges (typically under 250-300 yards). - How does the Core-Lokt bullet expand?
The Core-Lokt bullet is designed for controlled expansion. Upon impact, the exposed lead tip initiates expansion, and the lead core, which is mechanically locked to the copper jacket, mushrooms consistently. This creates a large wound channel and transfers maximum energy to the target while retaining a high percentage of its original weight for deep penetration. - What types of rifles are chambered in 7x57mm Mauser?
Many classic bolt-action rifles, especially those based on the Mauser 98 action, are chambered in 7x57mm Mauser. Modern rifle manufacturers also offer firearms in this caliber, appreciating its historical significance and effective performance. - How do I choose the right hunting ammunition for my needs?
Consider the type of game you'll be hunting, the typical distances you'll be shooting, and your rifle's preferences. For medium to large game, a bullet with controlled expansion and good weight retention like the Core-Lokt is ideal. For varmints, a lighter, frangible bullet might be preferred. Always test various ammunition types in your specific rifle to find what shoots most accurately. - What are the benefits of a Pointed Soft Point (PSP) bullet?
A Pointed Soft Point (PSP) bullet combines the aerodynamic advantages of a pointed bullet (better ballistic coefficient for flatter trajectories) with the reliable, immediate expansion of a soft point design. This makes it an excellent choice for hunting, where both accuracy and effective terminal performance are crucial.
