I killed two deer with my shockwaves last year,both dropped within 20 yds of where they were standing. The first one was on opening day ,shot high hit it in the spine deer went two feet straight down. Needed a pair of pliers to remove the broadhead when butchering,after cleaning it up you couldn't tell it from a new one. Second deer=complete passthrough dropped about 20 yds away in plain sight,I dont think he even new he was hit! They shoot just like my field tips. I wont use anything else,no need to. Dave
