Each cartridge features a 100-grain bullet constructed with a gilding metal jacket encasing a lead core. The distinctive feature is the patented V-shaped core cavity topped with a round polymer ball, crimped into place.

This specific design contributes significantly to its performance. The polymer ball is engineered to improve aerodynamics during flight and crucially, to enhance feeding in semi-automatic pistols by presenting a more rounded profile akin to hardball ammunition. This feature is critical for firearms known to be finicky with traditional hollow-point designs. The brass casing ensures reliable extraction and is compatible with standard firearm mechanisms.

The advertised Muzzle Velocity is 1600 ft/s and Muzzle Energy is 568 ft-lbs. These figures indicate a powerful round that aligns with the typical performance expectations for the .357 SIG cartridge. The lighter 100-grain weight is a key factor in achieving this high velocity while also helping to manage recoil, a crucial aspect for shooter control and follow-up shots. This combination of weight and velocity is specifically engineered for effective personal protection.

Performance & Functionality

The primary job of any defensive ammunition is to reliably feed, fire, and perform effectively upon impact. The Cor Bon 357 Sig 100 Grain Jacketed Hollow Point – PowRBall Brass Cased Pistol Ammunition PB357SIG100/20 44% Off excels in its core function of reliable feeding. Across all the firearms and magazines I’ve used it with, it has presented without a single hitch, even in semi-automatic pistols notorious for feeding issues. This consistent reliability is its most significant strength.

Functionally, the PowRBall design appears to deliver on its promise of controlled expansion. While I have not personally conducted ballistic gel testing for this review, the design suggests that the polymer ball delays the onset of expansion until deeper penetration into soft tissue. This delay is intended to allow for greater penetration before significant expansion, potentially leading to better weight retention and more consistent wound channels. The lighter projectile weight, as noted, also contributes to a more controllable recoil impulse.

One potential area for improvement, common to many JHP designs, is the overall penetration depth versus expansion ratio, which can be influenced by barrier materials. However, for its intended application of personal defense against unarmored threats, the performance has been more than satisfactory. It meets and, in terms of feeding reliability, exceeds expectations for defensive ammunition.

Design & Ergonomics

The Cor Bon 357 Sig 100 Grain Jacketed Hollow Point – PowRBall Brass Cased Pistol Ammunition PB357SIG100/20 44% Off showcases an innovative design centered around the patented PowRBall bullet.
