Is 32 ACP Viable for Self Defense? Is the .30 Carbine still a relevant caliber?

Underwood Ammo has some brand spanking new Extreme Cavitator Rounds that showed some really interesting results in the Ballistic Gelatin provided by Dr. Kote.  Pushing the enrgy dumps further it seemed that while they did not make as big of a initial wound channel compared to hollow points, they did create a longer wound channel.

Really interesting stuff if you like ammo!
