Went out to sight in my brand new Kodiak Mag 50.cal the other day. Shot once (off a lead sled...rock steady) and hit nothing. Walked up and shot from about 15 yards and hit about 4 feet low. I adjusted my scope all the way (cant be moved up anymore) up and im still hitting 3 inches low at 15 yards! It has luepold mounts and a luepold scope. Everythings tight but it does look like the scope is leaning a little down. Has anyone else had this problem. Please tell me i dont have to shim it.
