No experience on hogs, but I've taken a lot of large whitetail at .308 speeds with various 150 grain plain old soft points. I'm partial to the Speer Hot Core, but most any of them are well made and will do the job. I stick to the flat based ones in 150 grain as they seem to hold up better on tough hits. They're easy to find a load for. 4895, 4064 or Varget, if one of those doesn't work, you have a problem. Some of the premiums in 150 such as the Accubond should do nicely also. I really like the Speer GS for short to medium range, but the BC is rather low for 300 yards with a .308. If you want to step up to a higher BC, the Nosler 165 BT or Hornady 165BTSP would be a fine choice. The heavier bullets seem to hold up well in BT configuration. Run the numbers through a ballistics calculator. If the 150SP will work for you, go with that. Cheap to shoot for lots of practice. I've taken deer to 400 yards with them, just need a little dope past 250.
