Remington 788 ?

[highshooter]

When I go to eject the spent case it hits on the scope cap and falls back into chamber and must be removed by hand, when my dad bought his the scope was turned so the cap was on the wrong side, when he turned it around his did the same thing. I Assume this must be a common problem for this rifle? Is there anything to do besides turn the scope? One was .243 and the otther .308 if it matters.
