Sierra GameChanger 300 AAC Blackout 125gr TGK Rifle Ammo – 20 Rounds – The 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. Those who have suffered from (BBD) Blackout Bullet Disfunction, understand that most 30 caliber bullets require more velocity than the little Blackout is capable of when it comes to expansion. Sierra designed our 125 grain GameChanger bullet for optimum performance out of the 300 Blackout cartridge and gave it a muzzle velocity of 2115 FPS and a G1 BC of .298. Designed for moderate ranges on deer and hog sized animals, our 300 Blackout ammunition will give you the expansion and penetration needed to bring home the bacon. 2115 FPS Muzzle Velocity Designed For Moderate Ranges On Deer And Hog Sized Animals
