Sierra Ammo 300 AAC Blackout 125 GR TGK 20 rounds

Sierra 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.
