There are several thread on this in the ammo section here:
As for myself - I carried 9mm Hydrashok for many, many years (still have some in my P99c right now). But, I started using the 50 round boxes of the jacketed hollow point Winchester Rounds sold at Wal-Mart (the personal protection rounds). U get 50 for about the price of 20 of the other brands of hollow points. And, I read some tests someplace earlier this year, and they performed just as well as the higher priced brands.
Since I rotate ammo periodically, I bought some boxes of this, and have it in all my 9mms except fpr my P99c. WHen its next time to swop out the ammo, I'll be using the Winchester in that gun as well...
