Cor-Bon Pow'RBall .40 S&W 135GR Ammunition - 20 Rounds

CorBon Pow'RBall .40 S&W 135GR ammunition brings purpose-built defensive performance to your auto pistol. This 20-round box of polymer-tipped rounds combines aerodynamic design with reliable feeding and controlled expansion—ideal for shooters who demand ammunition engineered for duty, defense, or serious sport shooting.

The Pow'RBall design starts with a gilding metal jacket surrounding a lead core shaped into a patented V-cavity. Seated on top is a polymer ball, crimped and held firmly in place by the copper jacket. That ball does real work: in flight, it disperses air around the bullet to improve ballistic performance and feed reliability in semi-automatic pistols. At impact, the polymer tip delays expansion, allowing the bullet to penetrate 3–4 inches before the cavity is exposed, which then drives controlled expansion. The design also protects the hollow point from being plugged by clothing or intermediate barriers, ensuring consistent performance on target.

This is ammunition built by shooters who understand what works downrange. Whether you're stocking a carry gun, running defensive training, or demand ammunition with intelligent construction, Pow'RBall delivers the terminal performance and reliability that serious shooters expect from CorBon's reputation.

Frequently Asked Questions

Will Pow'RBall .40 S&W feed reliably in my auto pistol?

Yes. The polymer ball is designed to enhance feeding in semi-automatic pistols, making it a good choice for duty or carry guns that need rounds you can trust to chamber without hesitation.

How does the polymer ball improve performance?

The polymer ball serves three purposes: it improves aerodynamics during flight for better ballistics, it delays expansion at impact to ensure adequate penetration before the lead cavity is exposed, and it protects the hollow point from being plugged by clothing or obstacles that might prevent proper expansion.

Is Pow'RBall suitable for defensive use?

CorBon designed Pow'RBall specifically for defensive and duty applications. The controlled expansion and penetration characteristics, combined with the reliable feeding and hollow point protection, make it a purpose-built defensive round.

What's in each box?

Each box contains 20 rounds of Cor-Bon Pow'RBall .40 S&W 135-grain ammunition.
