Why the Core-Lokt design matters

The hallmark of the Core-Lokt is its progressively tapered copper jacket that is mechanically locked to the lead core. That lock prevents jacket-core separation on impact, which is why hunters have trusted this design for decades. Controlled expansion produces a balanced wound channel while high weight retention maximizes energy transfer and penetration—critical when facing thick hide, heavy bone, or long-range shots where consistent terminal performance is non-negotiable.

Field applications and caliber flexibility

REMINGTON CORE-LOKT exists in both soft point and pointed soft point configurations, and spans a range of bullet weights so you can match projectile mass to your intended game and rifle. Because models are available across virtually every centerfire hunting caliber, you can outfit bolt actions, lever actions, and single-shot rifles with the same proven expansion chemistry. Whether you hunt whitetail at typical rifle ranges or need dependable performance on larger game, the construction philosophy behind this product is focused on effective terminal results.

Range behavior and practical setup

While specific ballistic coefficients and drop charts depend on caliber and bullet weight, the Core-Lokt’s locked jacket/core geometry promotes consistent expansion without excessive fragmentation. That makes load development and zeroing simpler for field use—select the bullet weight that complements your barrel twist and hunting profile, then verify velocity and point of impact at typical engagement distances.

For a time-proven controlled expansion option in Rifle Ammo, REMINGTON CORE-LOKT remains a top choice for serious hunters and precision-minded shooters. Check current availability on our shop page to secure the right model and bullet weight for your mission. Check availability
