The Remington Core-Lokt 243 Winchester ammunition is built on seven decades of field-proven big game hunting performance. This 100-grain pointed soft point load delivers the controlled expansion and weight retention that has made Core-Lokt the go-to choice for hunters pursuing deer, antelope, and similar-sized game across North America and beyond. Each box of 20 rounds ships ready to feed reliable, accurate performance from your bolt-action or modern sporting rifle.
What sets Core-Lokt apart is its locked-core design—the copper jacket is mechanically bonded to a solid lead core, resisting separation on impact and achieving roughly 2x expansion while retaining weight for deep penetration and consistent terminal performance. The tapered jacket geometry promotes predictable mushrooming, which translates to cleaner kills and recovered game. At 2,690 feet per second with 1,945 foot-pounds of muzzle energy, this load is engineered to handle medium-range hunting scenarios where accuracy and stopping power matter equally.
If you're building or restocking your 243 Winchester hunting load, Core-Lokt offers proven results without guesswork—or premium ammunition pricing. It's the ammunition millions of hunters have trusted, and there's no reason to overcomplicate the choice.
| Cartridge | 243 Winchester |
| Bullet Weight | 100 grains |
| Bullet Type | Pointed Soft Point (Core-Lokt) |
| Muzzle Velocity | 2,690 FPS |
| Muzzle Energy | 1,945 ft. lbs. |
| Ballistic Coefficient (G1) | .356 |
| Rounds Per Box | 20 |
This load is effective on deer, antelope, and similarly-sized medium game at typical hunting ranges. The 100-grain weight and pointed soft point design balance trajectory and expansion for reliable performance in those applications.
The mechanical bond between the copper jacket and lead core prevents jacket separation on impact, ensuring the bullet holds together through hide and bone. This controlled expansion and weight retention generate deeper penetration and more reliable terminal performance than some competing designs.
While Core-Lokt is engineered and priced for hunting, shooters may use it for range practice or load development. However, it's built specifically for game-stopping results, so consider lower-cost target loads if your primary need is high-volume practice.
That depends on your rifle's specifications and twist rate. We recommend consulting your rifle's manual or manufacturer to confirm compatibility with any ammunition before shooting.
