Hornady HAP 10mm Auto 180gr Bullets

Hornady HAP (Hornady Action Pistol) bullets in 10mm Auto, .400 diameter, 180 grain (Hornady part no. 400421), take Hornady’s legendary XTP bullet profile and refine it into a dedicated competition projectile. Where XTP bullets use folds and a cannelure to aid controlled expansion and terminal performance, HAP bullets drop those features entirely, leaving a sleek, balanced projectile with a protected nose built purely for consistent, reliable feeding in semi-automatic pistols on the competition line.
