From what I've read and heard from many others is that hollowpoints will very often blow a nasty hole of an exit wound. The advantage is that it looses so much energy, it will usually not pass through the wall behind the person you shoot at, thus making it good for home defense.

If you guys want bullet fragmentation, you should see what a 5.56 NATO (.223 Rem.) does from a 20" barrel. At around 2500fps or better, the bullet completely disintegrates into about 43 peices. It's somewhat hard to use a full length AR-15 for home defense though.

My home defense weapon is an SKS-M. Thirty rounds of cheap Russian loaded (but good ammo) soft point 7.62x39. That's until I can scrounge enough cash to buy a Mossberg 590.
