CIIR, but i believe the Fusions are a bonded bullet. I shot 2 doe broadside through the lungs at 125 yards and got pencil hole in and pencil hole out. 165 grainers in a .308. Both deer were eventually found with very little blood trail. Broke some ribs, but i guess not enough resistance to expand. Next deer will get a shoulder shot. I was skeptical about a shoulder shot, but y'all make me feel a little better about it. Thanks all.
