Our GameChanger ammunition is the result of more than 70 years of designing world-class bullets. Each GameChanger round utilizes a Sierra Tipped GameKing bullet with an extremely accurate boat tail profile and a polymer tip seated in a hollow point design for fast expansion upon impact. A lead core encased in a thick, tough copper jacket delivers outstanding penetration and controlled expansion at any range.

A 180 grain Tipped GameKing travelling at 2960 FPS at the muzzle, well let’s just say it hits like the Hammer of Thor. Whether its Bear, Elk or Moose, our 300 Winchester Magnum GameChanger ammunition is up for the task. The 180 grain Tipped GameKing bullet has a G1 BC of .515. You are guaranteed to get Magnum results from our 300 Winchester Magnum GameChanger ammunition.
