Hrndy Hap 10mm .400 180gr 500ct

Hornady HAP 10mm .400 180gr ammunition offers handloaders a reliable, cost-effective projectile for precision reloading. HAP (Hornady Action Pistol) bullets are engineered specifically for semi-automatic pistol cartridges where consistent feeding and repeatability are critical. This 500-count bulk package delivers the volume serious competitors and range practitioners need to develop loads without depleting inventory between range sessions.

The .400 diameter 180-grain projectile features a gilding metal jacket that protects the bullet nose and core during the reloading process, critical for maintaining dimensional consistency and preventing jacket separation under pressure. The swaged core construction ensures uniform density, which translates to tighter velocity spreads and more predictable ballistics downrange. Smooth feeding geometry eliminates the chatter and hang-ups that plague inconsistent bullet designs, allowing progressive and single-stage loaders to work through high-volume sessions without interruption.

Handloaders working 10mm rounds—whether for USPSA/IPSC competition, practical pistol training, or defensive load development—benefit from Hornady's commitment to quality control and dimensional precision. The 180-grain weight in 10mm strikes a balance between velocity retention and recoil management, making it suitable for both standard and hot-loaded scenarios. At 13.19 pounds, this bulk case stores efficiently and represents significant savings compared to purchasing smaller quantities.

Hornady's reloading division maintains strict material and manufacturing standards across its product line. Handloaders who prioritize consistency and repeatability across hundreds of rounds will find that HAP projectiles minimize variables in the load development phase, allowing focus to remain on powder charge, primer selection, and case prep rather than projectile quality.
