Why do I think what happened? Me not making a good shot on the deer or the slug only penetrating the ground a couple of inches? As far as the shot goes, 100% my fault, I aimed a little too low and the deer's body was moving up as I pulled the trigger. As for the round only hitting meat and only going into the ground 2 inches from 60 yards away? I dont know, and dont really care, Ill be switching slugs. Ive had too many bad experiences with these ones.
Stop blaming the slugs and practice more! lol
