I have a lot of experience with game and the 150 SP at .308-.300 Savage speeds. I did go on a driven hog hunt several years ago in Texas with my M99 Savage in .300. 3 hogs were taken with the rifle from 125-350 lbs, all with the Hornady 150 SP. Head shots on the smaller ones in cover, shoulder quartering towards on the big one. All 3 died in their tracks. The quartering shot did not exit the hog, but passed through the vitals lodging in the far side of rib cage. I don't think more gun or bullet is needed than what you have. I would prefer the 150 grain weight for more shock and awe on impact, and less recoil for easier follow up shots if needed. I am, however, not a super fan of the Rem Core Lokt. They seem a bit erratic to me, and I've seen a lot of them pulled out of deer meat. Some perfect mushrooms, some shedding a lot of jacket and lead along the way. For your application in .308 Win, I would prefer in order: Speer GS, Speer Hot Core, Hornady interlock, Win Power Point, all in 150 grains. I've also heard good things about the Fed Fusion, but no personal experience here. Look for a Sav M99 in .308 or .300. Really fun for fast action, accurate enough for stand hunting.
