I'm with Tee jay,I also have taken this shot 3 times and watched all three deer walk about 20 paces and fall over. All 3 were dead within 4 to 5 minutes of the shot. Complete pass thurs on all 3 with lots of blood on the ground. I don't aim for the spine I aim left of it and picture the heart as my exit . To each his own but I say it is one of the most lethal shots there are.
