My .243 really likes the 58gr Superformance Varmint load from Hornady. I was coyote hunting in Oklahoma years ago when walking back to the trip I kicked up a hog along the creek bank. One shot in the neck and he fell into the water. A day later he surfaced and I fished him out. There's a very successful hog hunter in Texas who loves the 90gr TNT 6.5 Grendel load for American Eagle. Search for Double Naught Spy's videos on Youtube.
Thanks, Dinny
