Product Info for Sierra Bullets GameChanger .300 AAC Blackout 125 grain Sierra Bullets Tipped GameKing Brass Centerfire Rifle Ammunition

In 2011, the .300 AAC Blackout came along to beef up the M4 from 5.56mm NATO, and 300 Blk ammo has been in high demand ever since. Still used in many MSR's (Modern Sporting Rifles), many hunters have also picked them up for bolt-action match and hunting rifles. 300 Blackout Ammo comes in many different configurations for a variety of uses, but Sierra Bullets brings these to the table with one thing in mind: hunting.image

This 300 AAC Blackout ammo has a 125-grain Sierra Tipped GameKing (TGK) bullet, a boat-tail with a polymer tip for rapid expansion. This makes them perfect for dropping deer and hogs at moderate ranges. With a muzzle velocity of 2,115 fps (feet per second) and a G1 BC (Ballistic Coefficient) of 0.298, you can trust the lead core and thick copper jacket to penetrate and generate controlled expansion time and time again.
