If the hole is 'forward' - or advanced, clockwise when you screw the cap on, then you can also take the cap off and rub it on a bit of sandpaper.
Then refit it and repeat. Until the hole "moves" as it were, since it will shorten the cap a little and the hole will seem to move nearer to where you want it! anti-clockwise.
Potentially destructive, but spooky all the same!
