Hello ares0290, and welcome to the firearmstalk forum! You'll have to just ignore the first reply you received. You asked an honest question and didn't deserve to get a smart-assed admonishment in response because someone was itching to find fault with someone's question. So, instead of unhelpful, waste of time response you received earlier....I'll try to help steer you in the right direction for your question...
There have been a few new self defense ammo offerings brought to market recently. Hornady critical defense is probably the most publicized one. In addition to Hornady's new defense ammo, you'll find that Speer Gold Dot, Remington Golden Saber, and Federal HST are examples of typical factory loads you'll find to be recommended by other shooters for defensive purposes.
I've also seen recommendations for using lead semi-wad cutter hollow points, as well as full wad cutter slugs because of their expansion. However, the one caution I've seen over and over is to avoid ball ammo (aka FMJ's) because of their propensity to over pentrate by going into and through the bad guy and thereby create a hazard for innocent bystanders.
An important piece of advice I was given long ago is that we are responsible for every round that exits the barrel of our firearms, regardless of whether it is fired for defensive purposes. If you shoot the bad guy who was about to shoot you or someone else and your bullet goes through him and into someone minding his own business across the street, then you've done wrong and are going to be in big trouble. So for defensive purposes, you therefore should try to stick with a round that will rapidly expand and not over penetrate your intended target.
There are several good articles on the internet about this subject. Doing a yahoo or google search for "defense ammo" and similar keywords should help you find much more detailed information than what anyone could provide you in a single response to a forum posting.
I hope this at least helps to steer you in the right direction.
p.s. There is also a cable tv show on either the Sportsman Channel or Outdoor Channel that is doing a continuing series on ammo comparison testing for self defense. I might be mistaken, but I believe it is called Shooting Gallery and airs on Wednesday evenings.
