I have shot the Cor-Bon and the Pow-R-Ball ammo in wet newspaper tests back in the beginning of summer. I can tell you that Cor-Bon is very good self-defense ammo and will out penetrate the Pow-R-Ball ammo. However, the Pow-R-Ball ammo is not meant to penetrate as deeply but it will FRAG apart, causing more tissue damage to the surrounding area the bullet line takes. Pow-R-Ball usually was 1 to 1.5 inches less in penetration than the other self-defense ammo we tried in the test done.
Pow-R-Ball is usually a little "Hotter" by comparison, meaning the velocity is higher. I would not kick about one verses the other but be more concerned which one shot the best groups and functioned in my pistol without any problems. This is the main issue, so when you draw that pistol to fire and pull the trigger, it will indeed go BANG everytime you do so.
