I made a post about a 308 a few days ago. And the boy next door killed a 5 pt. yesterday with it. His dad told me he wanted to check the zero because the kid missed the first shot. We get it set up and see it's shooting about a foot high. We shot several times and can't get it to group. Finally my brain kicked in gear and i checked the scope and mounts to see if it was tight. NOT!!!! I got it tightened down and was able to zero it in just a few shots. I felt sorta dumb when it was all over for not checking this before we ever started. With a used gun ya never know who did what before you got it. She'll stack em now so thats all thats important.
