RE: 250 shockwaves
I've shot two deer with 250gr shockwaves. I believe you could probably select a better bullet. The entry wound and the exit wound were very similar in size on both deer. So I would say very limited expansion. However I recovered both deer. The one that ran went about 25 yards. The other I shot through the spine right below the head and just fell over like a card stood on edge.
I'm going hunting with 250gr Shockwaves tomorrow and I'll report back to this thread if I get one.
