After having not trusted mechanical broadheads for years, I was talked into trying then by my buddy. Shot a small deer at close range out of the stand, where it was slightly quartering away. The arrow went through the right lung and down into the heart before exiting out the off side shoulder blade. I was shocked that it absolutely demolished the shoulder, I mean shattered it. Deer didn't go 50 yards before flipping over dead. Absolutely a believer in these with a heavier arrow and a 70lb bow.
