Remington Core-Lokt Copper 270 Winchester ammo delivers controlled expansion and weight retention without the lead. This 270 Winchester ammo loads a 130-grain solid copper hollow point projectile driven to 3060 fps and 2703 ft-lbs muzzle energy — numbers that put deer, elk, and antelope down cleanly inside 400 yards. The copper monolithic construction holds together on impact, sheds no fragments, and meets lead-free regulations across all 50 states. Boxer primer, reloadable brass cases, non-corrosive propellant. Twenty rounds per box, made in the USA.
Built for the Box
Remington machines the Core-Lokt Copper projectile from a single piece of solid copper — no jacket separation, no lead core to fragment. The hollow point cavity initiates expansion on impact, and the rigid copper shank holds 95+ percent of its original weight through bone and tissue. The G1 ballistic coefficient of 0.287 keeps the bullet supersonic past 500 yards in standard atmosphere, though most hunters keep shots inside 300 where the flat trajectory and 2000+ ft-lbs retained energy guarantee clean kills. California Proposition 65 compliant, no lead exposure during handling or cleanup.

The Core-Lokt Copper line applies Remington’s century-old mushrooming design to a monolithic copper projectile — expansion starts at the hollow point tip and radiates back through pre-scored petals, creating a controlled wound channel that drops game fast. 270 Winchester ammo in this 130-grain configuration splits the difference between the lighter 110-grain speed loaders and heavier 150-grain penetrators — you get flat trajectory inside 300 yards and enough retained weight to punch through shoulder bone on quartering shots.
