I carry Gold Dot 230 gr (not the short barrel or +P). Here is a picture to demonstrate what I test for. Recently I got a box of the Hornady Critical Defense, and this is the result. I fired 10 rounds into wet newspaper with two layers of t-shirt and two layers of denim in front, from about 10' distance.
The same day I tried the Winchester PDX1 230 gr, and I only recovered one bullet (out of ten fired). The remainder went all the way through the 12" of wet newspaper and 12" of stacked cardboard to strike the hillside behind with considerable force; I assume that they did not expand. The one I recovered is on the left in the picture. On the right in the picture is a 230 gr Gold Dot tested on a different day under the same conditions, all 10 rounds fired that day looked just like that. The Gold Dot penetrated a little more than the Critical Defense. The Critical defense averaged about 8-9" penetration in the wet newspaper, the Gold Dot was about an inch more. I did not notice a significant difference in recoil or POI between the CD and PDX1.
I have also tried the older Taurus copper load (the same as the current CorBon DPX) and it was inconsistent in the G30 - some expanded beautifully, some did not. Same for Remington Golden Saber 230 gr.
In my full size 1911 I have also tested 230 gr Hydra-shok (only one expanded), Winchester SXT (none expanded), PMC Starfire (none expanded), and CorBon 230 gr JHP (inconsistent, some worked great, some did not expand). 230 gr Golden Saber worked pretty well in the 1911, and the Taurus copper was fantastic in the 1911.
I just got some 230 gr Ranger T, I hope to test it next week. And I would really like to get some 230 gr HST, but I have been unable to find any in stock anywhere.
