Ive been hog hunting and deer hunting with 223 for years. They heavy bullets work great!

Furthest hog kill is 335 yards with a 18" 8 Twist AR shooting 64gr Gold Dot loaded with CFE223. Closest kill was at the end of my suppressor when one snuck up on us.

Furthest Deer kill is 510 yards with a 77gr TMK out of the same 18" AR.

I see alot of people look down on a 223 but most of them have trouble killing a deer with a 300WM. And alot will go out and use FMJ and wonder why it ran off.
