I'm not passing judgement on your friend, but if its his first time adjusting a scope, he may be going the wrong direction. With some scopes, moving the scope adjustment "up" will move the point of impact up. While some other brands, moving the adjustment "up", moves the crosshairs up, causing the point of impact to be low. If that's not the case, he may want to try a bore-sighter and see what happens. If he still has no luck, he probably needs to have his scope checked for problems.
