Hornady FMJ Handgun 10mm Auto 180gr Full Metal Jacket bullets (Hornady part no. 40047) give 10mm Auto handloaders a rugged, full metal jacket projectile built around a cold-swaged pure lead core for consistent weight and balance shot to shot. Hornady builds this bullet with a flat point profile and a jacket thick enough to resist the distortion and separation that thinner-plated imports are prone to at 10mm velocities. It is a practical choice for high-volume 10mm practice and competition handloads where consistent feeding and accuracy matter more than expansion. Find it filed with our reloading bullets lineup.
