70 yards and you did not kill him???I don't know you or how you hunt, but if you use any scent products you have to try those silly "BUCK BOMBS".
They were like gold for me last year when they first came out and this year I shot and killed 2 OK bucks and 2 does that were all heading to the BOMB like they were dogs on a leash. If that buck you have your eye on is not paired up with a doe he WILL come in!!
