If you shoot through a perp in a defensive situation you may hit somebody behind the perp that you don't want to.
This to me is kind of a 'best of both worlds' approach. While having enough weight for good penetration and the ballooning design increases the diameter of the wound channel. 135 gr. Gold Dots are designed to expand at the 830 fps I'm looking for in 'my' bullet/cartridge combination. A heavy bullet designed to do the same i believe would be devastating. Kind of a 'best of both worlds' approach, or maybe a 'not as good as either cartridge' approach.
