Ammo question for savage 99?

Going pig hunting and planning to take my savage 99 in 308. Gun was manufactured in 1965. It shoots well but I dont want to run any hot rounds out of it. So question is what ammo would be recommended for pig hunting? Also do I need a higher energy round(hornady superformance federal HE round) for hunting large hogs. I have a ruger 77 in 308 which I have shot the hotter rounds with but would prefer the fast follow up shot of the 99. I was thinking of using federal fusion 165 grain loads, would these be good on hogs and does anyone have experience using them in a savage 99? Thanks
