Finicky feeding pistols are no match for Pow’RBall! We knew we needed to solve this problem by coming up with a round that looks and feeds like hardball ammo, but perform like a reliable hollow-point round. In 2004, Peter Pi, Sr. made bullet history. He believed that if he reshaped the bullet cavity, placed a polymer ball on top and crimped it in place it would solve the problem. The idea was so unique he was awarded a U.S. Patent #6,792,869. The patented Pow'RBall® design enhances feeding in those finicky pistols but it also delays the expansion of the projectile when it hits soft tissue, making it a more controlled expansion bullet. This controlled expansion gives you deeper penetration, better weight retention and more consistent expansion in soft tissue. The lighter weight projectile also reduces recoil and allows faster follow up shots. The Pow'RBall® has evolved into one of the most effective defensive rounds available today for personal protection.
