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 brings these to the table with one thing in mind: hunting. 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.

I built a 300 Blackout for my nine year old and his first hunt he harvested a 128.4 lb South Georgia doe using the Sierra Gamechanger. The shout was about 65 yards, great expansion and complete pass through. Energy dispersed very well and the doe jumped in tbe air, donkey kicked and ran about 20 yards…

Too expensive to plink withUp to 150 yards lethal on deer and feral hogsBetween 175-200 yards a few hogsI consider the 300 Blackout a 150 yard maximum on deerThis Sierra ammo is great300 Blackout no recoil. Almost no muzzle blastPast 150 yards the 270 winchester is my choice

Mine likes it good groups at 100 and 2 pigs down at about 75yd haven't used crono yet so not sure on velocity but judge on grouping can't be much of a spread so I'm happy with it and will continue to use

First off I haven't had a chance to shoot this ammo yet. Looks like the perfect round for a modern sporting rifle for hunting deer. The delivery time was fast. Ordered on Saturday and delivered cross country on Wednesday. If the weather works out I'll have this ammo chronographed and sighted in on Saturday. If all goes well I'll be getting a few more boxes in the coming weeks.
