Sierra has made one fine varmint and predator cartridge for the 300 AAC Blackout fans out there, and they did it by giving this round a 125 grain GameChanger bullet.

Also known as the Tipped GameKing, the GameChanger possesses a perfectly concentric jacket, drag-reducing slanted base, spearlike polymer tip, and precise weight that all contribute to this round’s 0.298 G1 ballistic coefficient. In layman’s terms that means this round covers 250 yards in about 0.42 seconds, at which point it has energy to spare at 640 ft lbs. Accuracy and power like that together is small game’s worst nightmare.

The GameChanger’s polymer tip isn’t just an accuracy enhancing feature. It’s seated in a hollow point nose cavity, so when impact drives it inward it forces the bullet’s dense lead core and thick copper jacket outward in a display of devastating terminal expansion. Sierra optimized this bullet to expand reliably even with the 300 Blackout’s relatively light power behind it, so you can count on your rifle to see you through your hunt.

Sierra pays as much attention to loading ammo as they do making match grade bullets. This round’s new brass case, responsive primer, and hygienic propellant are loaded by discerning experts and then rigorously inspected to ensure you get some of the best ammo on the market!

Would this ammo work for self-defense? Well, humans may be marginally smarter than coyote, but we’re not otherwise built all that differently from them.
