I love my AR10, 7.62x51 (.308 Winchester).
Ammo’s easily available, not expensive, AND it hits a ton.
Best hog rifle in my Armory - AR-10, Nikon 50mm glass, with 45 degree BUIS, 800 lumen (green) predator light with thumb switch.
Hornady Whitetails work just fine, thank you very much.
Although the 300 blackout DOES present the “NEED” for another firearm, and there IS room in the safe after the boating accident ...
