RE: Do Shockwaves expand?
Go with a Barnes Expander or Nosler Partition bullet. They are not as expensive as you think. I have used the Barnes Expander TEZ a couple of times now and the result has been exceptional, damage and blood trail second to none. I have had no blood trail due to poor expansion with perfectly placed shots with other bullets. I shoot Shockwaves and Powerbelts at paper at the range.
