20rds - 270 WSM Winchester 150gr. Supreme Elite XP3 Ammo

Winchester Ammunition 150 Grain Polymer Tipped Ammo Details

Founded in 1866, Winchester is perhaps the biggest name in the shooting world. Since it’s beginning, the company has been dedicated to innovation, quality, and performance. Winchester Supreme Elite XP3 ammunition combines the best qualities of their Fail Safe, Accubond, and Ballistic Silvertip rounds. The result is the finest hunting bullet the company has ever offered.



This package contains 20 factory fresh rounds of Winchester Supreme ELite XP3 .270 Win Short Mag ammunition. Each cartridge features a 150 grain XP3 polymer tipped projectile. These proprietary bullets feature a bonded core for hard-hitting weight retention and deep penetration, a boat tail configuration for in-flight stability and better long range accuracy, and a polymer tip that increases ballistic coefficient and initiates terminal expansion. These bullets also feature a Lubalox coating to reduce barrel fouling and engraving force, making them gentler on your firearm.



Use these effective and versatile loads for everything from deep woods whitetails to open prairie pronghorn. Each round produces a muzzle velocity of 3150 feet per second and a muzzle energy of 3304 foot pounds. This non-corrosive ammunition is boxer primed in reloadable nickel-plated brass cases.
