Federal pairs Barnes’s all‑copper Expander bullet with carefully tuned powders and premium components to extract maximum performance from the .357 Magnum. The solid‑copper hollow point opens into six sharp petals while retaining 100 % of its weight—delivering deep, straight‑line penetration for medium‑game hunting and personal defense. A nickel‑plated case resists corrosion and slips effortlessly from revolver cylinders and lever‑gun chambers, while a fast 1,400 fps muzzle velocity flattens trajectory and transfers more than 600 ft‑lbs of energy on impact.
 
Key Features
Barnes Expander All‑Copper HP: six‑petal design delivers reliable expansion and full weight retention for decisive wound channels.
Nickel‑Plated Brass Case: smooth feeding and extraction, plus enhanced corrosion resistance in harsh environments.
Full‑Power Ballistics: 1,400 fps from a 6‑inch barrel produces 609 ft‑lbs of muzzle energy for confident medium‑game stops.
Clean‑Burning, Temperature‑Stable Powder: consistent pressures and reduced fouling keep accuracy tight during extended sessions.
