FWIW, I grew up shooting hogs with a .308, and never shot anything but 150 gr Remington Core-Lokt. I never had one walk away, but also always got a head, spine, or vital shot. Weights ranged from 80lbs-250 lbs.
Pretty much any .30 hunting bullet is going to perform adequately.
A word of warning, don't shoot the big ones too far from the truck unless you have a cart. I shot my biggest about 4 miles from the truck with youthful excitement as my guide. That gave out after the first 1.5 miles of dragging!
Just don't gut shoot one. IMHO, smells infinitely worse than a gut shot deer while cleaning it.
