I use 165gr Gold Dots, 155gr Hydrashoks, and 165 SXT Rangers. I like to spice things up a little .
This is what I've been able to gather from various bullet tests, research, blah, blah, blah, and hopefully I remember it right.
The Gold Dots are what my local Deputies use. They are a little newer than the others I believe, and score the same or above the Hydrashoks. I got 50 for $16 at a gunshow.
The Hydrashoks are the oldest IIRC. They are the softest recoiling and the quietest by far. These are pretty much what everything else is judged by. I heard they recently came out with a new design that is much more effective. I got 20 for $14 at Sports Authority.
The SXT Rangers aka "Black Talons" recoil the hardest without a doubt. Their unique design makes the round open up and uses sharp edges tto slice through whatever it might encounter. They score as well or better than the Hydroshoks. I got 50 for $15 at a gunshow.
A bad guy won't be able to tell the difference, that's why I keep a mag loaded with each .
