The Glaser PB38100/20 PB3810020, also known as the Pow\'Rball, features an innovative design. It is essentially an expanding lead bullet, crowned with a polymer ball, creating the profile of a full metal jacket or a rounded ball. Unique to this product is the specifically engineered cavity within the lead bullet core. Upon impact with a target, the soft point cap induces a controlled expansion of the bullet, ensuring a tailored performance.
