IMHO...Hogs are tough critters. I went hog hunting once and shot 3 of them with a 300 Win Mag...one of them I knocked rolling. Didn't find ANY of them...Found out later that a Hog's vitals are further forward than most critters,,mostly between their front shoulders. Anyway, I would go for the 308 because it is more versatile than the 7-08 as far as hunting big game goes. and you can get surplus military ammo cheaper if you want to stock up. You may never hunt Elk sized game, but if you did, you'd be a LOT more comfortable with a 308. I. myself just ordered a 30-06 for that very reason.
