Hornady 40 S&W/10mm Auto 180 grain FMJ-FN bullets are a reliable choice for reloaders who run high-volume practice sessions or competition on a budget. The 400-diameter design works in both .40 S&W and 10mm Auto platforms, giving you flexibility across your handgun collection. These full metal jacket rounds are engineered for consistent feeding and function in semi-automatic pistols, so you spend more time downrange and less time troubleshooting.
What sets Hornady's FMJ line apart is build quality. The jacket is robustly constructed to resist deformation on impact—a real advantage when you're loading ammunition that will see hard use in action pistol matches or high-round-count practice days. The core is cold-swaged from pure lead, which ensures balance and flight stability shot to shot. That consistency translates to tighter groups and predictable performance, which matters whether you're working on fundamentals or chasing a new personal record.
The FMJ-FN design (flat nose) was engineered without expansion-aiding skives, keeping the bullet profile clean and optimizing feeding reliability in semi-automatic handguns. No exposed lead at the nose means you won't risk jams from soft-point deformation—a real concern in competitive or high-speed shooting where a failure costs time or position. These bullets are built for the reloader who demands consistency and dependability without premium pricing.
