The Remington Core-Lokt Copper 308 Winchester load answers the call for lead-free hunting ammunition without sacrificing the expansion and weight retention shooters expect from the Core-Lokt name. Chambered in 308 Winchester, this 150-grain solid hollow point monometal bullet is constructed from high-strength pure copper, engineered to shed no lead fragments while delivering controlled mushroom expansion on impact. Muzzle velocity of 2820 feet per second and muzzle energy of 2648 foot-pounds place this load in the center of the .30-caliber hunting spectrum — adequate for whitetail, mule deer, pronghorn, and black bear at ranges from zero to 300 yards. Federal and state regulations in California, condor zones, and select wildlife management units require non-lead projectiles; this load meets those mandates while maintaining the accuracy and terminal performance Remington developed over decades of Core-Lokt engineering.
Performance at a Glance
Remington builds the Core-Lokt Copper bullet from a single piece of copper bar stock, machining the hollow point cavity to a depth and diameter calculated to initiate expansion at velocities above 1800 fps. The absence of a lead core means the bullet retains 95-100% of its original weight after impact, driving deep penetration through shoulder bone and vitro. The solid copper construction eliminates the jacket-core separation that can occur with cup-and-core bullets under high-velocity impacts or oblique bone strikes. Boxer primers and reloadable brass cases allow handloaders to tailor velocity and seating depth for specific rifles. Each box contains 20 rounds of new-production, non-corrosive ammunition manufactured in the United States.

Copper bullets produce lower barrel pressures than lead-core equivalents at the same velocity, but the longer bearing surface of the monometal projectile requires a faster rifling twist to stabilize — most factory 308 Winchester rifles ship with 1:10″ or 1:12″ twist rates, both adequate for 150-grain copper bullets. Verify your rifle’s twist rate before purchasing if you shoot a custom barrel.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Treat every firearm as if it is loaded. Keep muzzle pointed in a safe direction at all times.
- Verify current federal, state, and local regulations regarding ammunition purchase, possession, and transport in your jurisdiction.
- This product contains copper and other materials known to the State of California to cause cancer and reproductive harm (Prop 65). Lead-free does not mean risk-free — handle fired cases and cleaning materials with care.
