Gold Dots, I thought were plated, and really designed for lower velocities, no?
My own informal tests showed the 180 GD pretty much self destructing @ 1,230 into a gallon of water, where jacketed bullets tended to expand intact.
Not all apples to apples, but here's the link
The 10mm, for me, is "this year's hobby", and at 650+ loads I've kinda gone overboard. Fun to shoot, good woods gun for most of the 48, and, I imagine, fantastic at dispatching cover-taking zombies
I digress. Bottom line is it shoots anything faster than the .40, and that may make it better, or inferior, depending on the perceived need.
Water isn't a very good analog, basically everything expands violently in water compared to tissue.
