Description
The Remington Core-Lokt 7mm Rem Mag has been the go-to ammunition for serious hunters for over 75 years, and it's easy to see why. The 150-grain Core-Lokt pointed soft point bullet combines a tapered copper jacket mechanically locked to a solid lead core, which delivers approximately 2X expansion with impressive weight retention. That engineering matters when you're after elk or other large game at distance.
What Makes the Core-Lokt 7mm Effective
Out of a 7mm Rem Mag rifle, this load runs at 3110 fps with 3221 foot-pounds of muzzle energy. The pointed soft point design provides a flat trajectory while the controlled-expansion bullet construction ensures consistent, reliable performance once it finds its mark. Penetration averages around 20 inches in ballistic gelatin, and the bullet typically retains about 75 percent of its weight, meaning it won't shed fragments and lose stopping power deep in the animal.
Brass Cases and Reloadability
These cartridges come with reloadable brass cases and non-corrosive boxer primers, making them practical for reloaders looking to stretch their ammunition budget. Whether you're building a hunting ammo cache or working up loads for your 7mm, the quality brass foundation makes these worth saving and processing.
Field-Proven Performance
With generations of hunters trusting this exact load, you're not experimenting with unproven technology. The Core-Lokt platform represents serious hunting tradition backed by real-world success. The 150-grain bullet weight strikes a balance between velocity and stopping power that works well in the 7mm Magnum case, giving you a load that handles everything from deer-sized game to elk, particularly when you put the bullet where it matters.

Frequently Asked Questions
Can I reload these Core-Lokt cartridges?
Yes, these rounds come with reloadable brass cases and non-corrosive boxer primers, making them suitable for handloading. Once you've fired them, you can clean and process the brass to reload with your own powder, primers, and bullets.
What game is the 150-grain Core-Lokt 7mm suitable for?
The 150-grain load works well on deer, elk, and other large game at medium to extended ranges. The bullet's controlled expansion makes it reliable on larger animals, though it's also effective on smaller game when placed properly. Many hunters prefer this weight in the 7mm Magnum for its balance of velocity and stopping power.
How does the controlled expansion in Core-Lokt bullets work?
The Core-Lokt design uses a tapered copper jacket mechanically locked to a lead core, which controls how the bullet expands when it strikes game. This keeps the bullet from separating or fragmenting excessively, ensuring deep penetration and reliable performance. The design typically produces around 2X expansion with approximately 75 percent weight retention.
Is the Core-Lokt PSP different from the newer Core-Lokt Tipped?
Yes. The standard Core-Lokt PSP has an exposed lead tip and a ballistic coefficient of .346, while the newer Tipped version has a polymer tip for better long-range ballistics and higher BC. Both use the same proven jacket-lock design, but the Tipped version is optimized for shooters who hunt at longer distances.
