There's truth in this thread, but let me add that velocity *does* matter when using bullets meant to expand! I'm not sure what velocity the Gold Dots need for expansion, but in my opinion, that needs to be taken into consideration.
When expansion velocity is achieved, then accuracy definitely is key! Expansion means nothing if you haven't hit your intended target!
I've had great results with Ramshot Silhouette and GD bullets for my 9mm loads...
