By all indications with the tissue and lung damage it expanded quite nicely and didn't just poke on through. I feel it did a great job and have been very impressed with the E-Tip in my son's rifle. I shoot the 100 gr. Partition in mine, but I might have to try the 90 gr. E-Tip and see if it shoots for me in my rifle. Here are a couple tests I did with water jugs as I wanted to see how they were working for me.
100 yards
90 gr. E-Tip (6mm) - 30-06 165 gr. Accubond - (6mm) 100 gr. Part.
