Hornady 375D round balls are precision-swaged lead projectiles purpose-built for traditional muzzleloading. Whether you're shooting a flintlock, percussion cap, or modern inline, these .375-diameter balls deliver the consistency that matters downrange. Each box contains 100 balls, giving you plenty to develop loads and shoot groups without constantly recasting or sourcing from multiple suppliers.
The difference between mediocre and match-grade muzzleloader ammo often comes down to uniformity. Hornady's cold-swaging process eliminates the air pockets and voids that creep into cast balls, resulting in truly consistent weight and balance across the batch. That uniformity translates to tighter groups and more predictable performance—especially critical when you're hunting or competing at distance where every variable counts.
Pure lead construction keeps things authentic and is the material of choice for traditional muzzleloading. The smoother, rounder surface finish promotes reliable rotation and concentricity in the bore, which contributes to the accuracy you expect from hand-loaded ammunition. Before you buy, verify your rifle's bore diameter and confirm whether you'll be shooting them patched or with a compression fit—bore size and loading method determine which ball diameter works best in your gun.
