Hornady Superformance .300 Winchester Magnum Ammo 180gr SST 20 Rounds

Hornady® Superformance™ .300 Win Mag Ammo 180gr SST® ammo is a performance-enhanced centerfire hunting cartridge featuring a polymer-tipped Hornady® SST boattail bullet designed to deliver consistent expansion and superior weight retention by minimizing core-jacket separation. Reloadable brass casings deliver smooth operation and reliable feeding. For optimal results with a gas-operated semi-auto firearm, it is recommended that all Hornady Superformance ammunition be paired with rifle-length gas systems and barrel lengths of 20" or longer. Any barrel and gas configuration of less than 20" is best served with the installation of an adjustable gas system, especially if firing suppressed. Made in USA.
