I think I do but their results are not always good - I dig up the pics...

But back to the Gold Dots - here is a picture of a bisected GD. You can see in the left hand picture the "cooper dot" that stops, for the most part, the expansion of this bonded bullet. I do not have a pic of a 250 but this "copper dot" is much farther down into the bullet at the bottom of the really deep hollow point. With the deep HP they have been able to lengthen the bullet which really helps in a sabot load.
