Australians are pretty tough, and Australian hunters are some of the toughest of them all. Whether they’re hunting buffalo in croc infested swamps, stalking deer in the snow (yes it does snow), or tracking bush pigs across some of the harshest terrain on earth, they want reliable ammunition – Australian outback. Our new high energy propellants drive the 165GR Sierra SBT Gameking bullet 2840 ft/s (at 70 degrees Fahrenheit), offering considerable velocity gains over other factory ammunition with the same bullet weight. Coupled with our unique ballistic temperature independence technology ensuring consistent velocity across an extreme temperature range, it’s an unbeatable combination. Australian outback – extreme performance, whatever the weather.
