I have killed with Sciroccos. I have not tested any Fusions. THe Sciroccos have been dead-right-there shots with no exits. My b-i-l shoots them in his 300 Wby & 7 RM. I have all four of his recovered bullets. They do exactly as advertised. They retain 80% of their original weight. The mushrooms measure 3/4" in each case. I still don't know what to think of the no "exit strategy" of the Scirocco's. On the one hand we discuss the what-if's thinking that if this critter hadn't dropped on the spot then there would be no blood trail. But, in each case they all did drop within 20 yards. Can't exactly support an argument with those results.
My choice in your situation would be to go with the softer bullet assuming you are shooting a 308 Win.
