Speer 5129 .45 caliber muzzleloader lead balls are purpose-built projectiles for traditional black powder shooting. Each 100-pack contains 128-grain pure lead round balls—the classic, reliable choice for flintlock, percussion cap, and inline muzzleloaders where authentic performance and proven accuracy matter. Whether you're hunting with a traditional rifle, competing in a muzzleloader match, or simply stepping back to fundamentals, these swaged lead balls deliver the consistency and precision that have made them a staple in the sport for generations.

Speer manufactures these balls through a controlled swaging process designed to eliminate voids and air pockets, resulting in uniform weight and balance across the entire batch. That uniformity translates directly to predictable velocity, reliable bullet placement, and tighter groups at the range or in the field. The smooth, round surface promotes reliable engagement with the rifling, supporting the kind of rotation and trajectory stability that builds confidence in your shot.

At .45 caliber and 128 grains, these balls suit a wide range of traditional and modern muzzleloading platforms. Whether you're loading over black powder or modern substitutes, these lead projectiles pair with cloth patches and your chosen powder charge to deliver the ballistics your specific rifle demands. A 100-round supply keeps you fed for range sessions, hunting trips, or competitive shooting without constant restocking.
