Dakota Ammo's Cor-Bon Pow'RBall: Cor-Bon Pow'RBall was originally designed to eliminate feeding problems in pistols that would choke on the new large mouthed JHP bullets. The patented Pow'RBall projectile is a JHP bullet with a polymer ball crimped in the tip. This tip enhances feeding in those finicky feeding 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 makes recoil recovery much easier for follow-up shots.
