Not many times have i dropped a deer in its tracks using a CB. Twice that i can remember, shot one facing me throught the throat patch the other was a shoulder blade shot. I don't recommend either of those shots to a beginner. No can of worms friend, Spitfire mech 100 gr is a very good BH. Slicktricks standard, mag or best razortrick. Almost all of my deer have fallen in sight of me, they can & do run after being hit. Good hit through ribs good sharp BH deer will be down with-in 75 yds or less. After the shot watch the deers travel direction lots of times i hear them running & falling to the ground
