Seein' as how I live about 10 minutes from them, I have used them extensively.
I used to use their 9mm, 40 S&W and 45ACP bullets for IDPA and USPSA. Time was you could walk in a buy their seconds. Between a couple fellow shooters and myself, we probably went through 100,000 rounds in a span of about 3 years. They're pretty big with the game shooters up here who reload. I've never heard anything bad about them.
As far as their hollow points for self defense, I don't know. I've shot them, but never "tested" them. I only use factory ammo for carry ammo (unless it's 44mag or 45 Colt when tromping through the woods).
