I shot the two blades. Of the three deer that I shot with them, only one was a pass through (doe, 17 yards quartering away) and even on that hit, the entry wound was less thanan inch across. After shooting several types/brands of expandibles over the last 10 years, I've found that my slick tricks will shoot just as well and I only have to worry about my shot, not if the heads will work the way they should.
