It's almost as if the sprue plate is loose. I have checked the bolt that secures the sprue plate and it is a tight as it goes.

While the mold is cold, hold it up with a good light behind it. You should not be able to see any light between the plate and the top of the mold. If the plate is warped you can usually see it.
It isn't hard to remove a little bit using a decent flat bench stone, and it could be as simple as one side or corner is all that is needing attention.
If it's good cold, then warm it up and repeat.
It could be that the screw is actually too tight and might need to be loosened up a tiny bit. Sometimes they will pull the plate up just a hair when they heat up.
It was recommended to me to tighten the screws only to the point that the plate would just barley swing out on it's own weight. This is fine of course, if you have the added set screw to make sure it doesn't keep unscrewing while your pouring bullets. However, you can still back it out just a touch without the set screw and still have a nicely functional swinging plate.
