CorBon Pow'rball 357 SIG 100 grain ammunition represents a specialized defensive round engineered for controlled expansion and reliable feeding in semi-automatic pistols. The 100-grain projectile combines a gilding metal jacket with a lead core shaped in a patented V-configuration, topped with a polymer ball crimped into place. During flight, the polymer ball optimizes aerodynamics by dispersing air around the bullet, improving ballistic coefficient and trajectory stability. In the magazine and chamber, the ball design enhances feeding reliability in autoloaders—a critical consideration for carry weapons where chambering failures are unacceptable.
The expansion mechanism is where Pow'rball rounds distinguish themselves. Upon impact, the polymer ball delays the onset of jacket separation, allowing the projectile to penetrate several inches into the target before the ball is dislodged and the lead core is exposed to initiate controlled expansion. This two-stage penetration profile creates predictable energy transfer while minimizing over-penetration in defensive scenarios. The 357 SIG cartridge, operating at approximately 1,450 feet per second from typical barrel lengths, delivers velocity advantage over standard 9mm loads while remaining manageable in recoil. Each box contains 20 rounds, with bulk case quantities available for range training or duty stock.
This ammunition suits law enforcement personnel, armed security professionals, and civilian carriers who have selected 357 SIG platforms and seek premium defensive ammunition with documented feeding and expansion characteristics. The 357 SIG round itself occupies a performance niche between 9mm and 40 S&W, offering higher velocity and flatter trajectory while maintaining manageable recoil in duty-sized handguns. CorBon Pow'rball rounds have established a reputation for consistent performance in this specialized caliber, making them a practical choice for shooters who demand reliable function and measured terminal performance from their defensive load.
