The Federal Premium Terminal Ascent .300 Winchester Magnum 200-grain Polymer Tip Nickel-Plated Brass 20-round box is an elite centerfire rifle cartridge engineered specifically for harvesting heavy big game—including elk, moose, caribou, and bighorn sheep—at extreme downrange distances. A primary friction point when hunting with traditional long-range magnum ammunition is the severe tradeoff between terminal performance thresholds: bullets designed to expand at low velocities far downrange often fragment violently on close-range impacts, while tough close-range bullets fail to expand at extended distances as impact speeds decay. Federal Premium resolves these terminal and ballistic limitations by pairing its nickel-plated reloadable brass cases with the molecularly bonded Terminal Ascent projectile, delivering extreme weight retention, ultra-low drag trajectories, and reliable terminal expansion across all velocity spectrums.
The primary technical advantage centers on Federal’s advanced Terminal Ascent projectile design paired with an extraordinary 0.608 G1 ballistic coefficient. Featuring a hollowed Slipstream® polymer tip that initiates rapid expansion even at velocities up to 200 FPS lower than conventional polymer tips, the bullet provides instant mushrooming at extreme distances. The solid copper shank is molecularly bonded to a rear lead core, preventing core-jacket separation under high-velocity close-range impacts to retain over 70% of its mass for deep bone-crushing penetration. Proprietary AccuChannel® grooving along the bullet shank minimizes bearing surface drag, reduces barrel fouling, and helps maintain match-grade accuracy.
Launching its heavy 200-grain bonded bullet at 2,810 FPS, this Terminal Ascent loading maximizes the high-capacity .300 Win Mag casing to maintain velocity, flatten downrange holdover, and resist severe crosswind drift. Assembled using premium reloadable nickel-plated brass cases, low-friction clean-burning propellants, and non-corrosive Gold Medal Boxer primers, the nickel coating protects against corrosion during harsh mountain hunts while providing ultra-slick chambering and extraction across bolt-action precision rifles. It is an industry-leading choice for open-country big game hunting and western mountain pursuit.
