Federal Premium ammunition for the 300 Winchester Magnum starts with primers subjected to frequent inspections for dimensional tolerances and charge weight, ensuring consistent ignition. The propellant is specially formulated to Federal specifications—clean-burning powder of the highest industrial grades, selected for consistency and reliability. The precision-built cases feature nickel-plated brass that resists corrosion and promotes smooth extraction in extreme conditions.
Trophy Copper ammunition delivers pinpoint accuracy with aggressive expansion. The copper, polymer-tipped 180 grain bullet retains up to 99 percent of its weight for deep penetration across medium and big game. This is the official rifle ammunition of MeatEater’s Steven Rinella.
