Hornady 400421 HAP 10mm .400 180 Grain Hollow Point Reloading Bullets, 500 Count

Hornady HAP bullets are designed for competitive pistol shooters and handloaders who demand consistent performance from every round. Modeled after the proven XTP bullet design, the Hornady Action Pistol (HAP) projectile is refined specifically for target and competition applications. Its streamlined profile promotes reliable feeding in semi-automatic pistols, while the protected nose helps maintain consistent bullet geometry during handling and loading.
The HAP design removes the folds and cannelure used on XTP bullets for controlled expansion and terminal performance. This creates a sleek, balanced projectile focused on accuracy, dependable cycling, and uniform results on the range. The hollow point profile and copper jacket support consistent flight characteristics, making these bullets a practical choice for precision-focused 10mm handloads.
Each Hornady 400421 box contains 500 unprimed reloading bullets. The projectiles feature a 180-grain lead core, copper jacket and copper coating, with a .400 caliber diameter and .164 ballistic coefficient. A sectional density of .161 contributes to predictable external ballistics when paired with suitable load data. These bullets are intended for handloading applications and should be assembled only with current, verified data and components appropriate for your firearm and cartridge.
