After seeing the test data from the Memphis PD range testing - where they tested the Hydra-Shoks they were using, Gold Dots, and about 10 other brands - I won't be using anything but Gold Dots anytime soon. My Hyrdra-shoks are now range ammo. I posted about this some months ago, and since found out that I am prohibited from posting the actual test results, but suffice to say that with 'standard' testing media - drywall, clothing of various thickness, gelatin, auto glass, wood, and beef - the Gold Dots were the only ones that didn't have any jacket separations. YMMV.
