Hedge,we try to shoot pigs in the 150 # range,to eat,but with the bigger pigs,the size you 're referring to,shoot them right over the front leg,kinda low,and go for heart shots.If your arrows are heavy,and your points sharp,you wont have any trouble.You can slip an arrow into the vitals on a quartering away shot,but I'd refrain from the advise to stay back.Hogs have odd shaped lungs,like a inclined teardrop.Study their anatomy and you'll see where you need to hit. Hope y'all get some pigs and have a good time. God Bless
