Description
Remington's Core-Lokt Copper brings the proven performance of the legendary Core-Lokt line into the all-copper category. This is a monometal bullet design with no lead core, meaning you get excellent weight retention and deeper penetration on game. The precision hollow point ensures consistent expansion across a wide range of velocities, making it dependable whether you're hunting at typical range or pushing distance.
What Makes Core-Lokt Copper Different
Unlike traditional Core-Lokt rounds that use a lead core with copper jacket, the Core-Lokt Copper is engineered from high-strength pure copper throughout. This all-copper construction delivers near 90% or better weight retention, translating to maximum energy transfer and deep, reliable penetration. The hollow point design opens consistently, providing the expansion needed for effective hunting without sacrificing the structural integrity of the round.
The 85 Grain Load for .243 Winchester
The 85-grain bullet weight sits right in the sweet spot for medium game like deer and antelope. It's pushed to 3,200 feet per second, generating 1,933 foot-pounds of energy. This combination gives you flat trajectories and plenty of stopping power while staying in the mid-range for the .243 Winchester caliber. The brass casing is reloadable, and the lead-free primer makes these rounds suitable for various hunting conditions without compromise on ignition reliability.
Clean Shooting and Field-Ready Performance
Copper bullets tend to run cleaner through your barrel than traditional lead-core designs, which means less fouling and more consistent accuracy shot after shot. This is standard Remington quality ammunition, loaded with precision techniques and quality components you can count on. Each box delivers 20 rounds of field-ready ammunition built for hunters who expect their ammo to perform when it matters.
