Hornady HAP 10mm .400 180gr Handgun Bullets

Hornady HAP: Competition-Grade Handgun Bullets

The Hornady Action Pistol (HAP) bullet represents a refined approach to handgun ammunition development, engineered specifically for shooters who demand precision and reliability.

Design Philosophy

Modeled after Hornady's legendary XTP design, HAP bullets strip away unnecessary complexity to create a sleek, balanced projectile. Unlike traditional designs that rely on folds and cannelures for expansion, HAP bullets achieve their performance through pure engineering excellence—a protected nose design that ensures consistent, reliable feeding in semi-automatic pistols.

Construction

Core & Jacket: The heart of every HAP bullet is a cold-swaged pure lead core encased in a copper jacket. This construction delivers:

• Consistency: Uniform weight and balance across every round
• Flight Stability: Predictable ballistic performance downrange
• Feeding Reliability: The protected nose prevents jams and feed failures

Why Competitive Shooters Choose HAP

Hornady HAP bullets have earned their reputation among competitive shooters for one simple reason: they deliver pinpoint accuracy with every shot. The combination of cold-swaged construction and balanced design produces the kind of consistency that separates winners from the rest of the field.

Whether you're loading for IPSC, IDPA, or simply perfecting your craft at the range, HAP bullets provide the economical, reliable foundation for custom ammunition tailored to your specific shooting needs.
