any dang thing you want, yet if FMJ then head only shots IMHO.
small meat hogs under 100 I'd use suppressed 10/22 and subsonic ammo... but since you said the AR... I actually like the small barnes bullets. Very little damage. Kill well enough. According to some to expensive... of course they have almost 1000 in a gun and optics, 2000 if suppressed... so that theory is out the window for me.
Others... 63 Sierra semi point was always pretty good. Most 55 soft points are too frangible for our tastes. OTOH we have lots of heavier IE 69-77 ish match hollow points around and they have never left us wanting and usually not that much damage though the damage from them tends to be somewhat variable.
You can go frangible. But it might destroy meat...
We run 40 vmax at home since there are so many houses around.. if you can keep it in the ribs it works great. Which is hard on running hogs at night with a thermal. But the first one you can control.
If its 150 pounds or less it won't take a lot of killing for sure.
