Speer
Speer Bullets 5137 muzzleloader .45 caliber black powder lead balls are purpose-built for traditional and inline muzzleloaders that fire round-ball ammunition. At 144 grains per ball, these are cast from pure lead using a controlled swaging process engineered to eliminate voids and air pockets—the kind of consistency that separates reliable field performance from frustrating shot-to-shot variation. Whether you're hunting deer with a flintlock, competing in muzzleloader matches, or testing loads at the range, uniform projectiles matter when you're working with black powder ignition and open sights.
The manufacturing process creates smooth, symmetrical ball geometry without defects. That surface uniformity promotes stable flight characteristics and consistent velocity downrange, which translates to tighter groups and predictable point-of-impact—especially important when you're limited to a single shot before reloading. A hundred rounds per box gives you enough for a serious hunting season or a full day of load development without constantly reordering.
Speer's reputation in the ammunition business rests on quality control and materials, and these lead balls carry that standard into the muzzleloading space where precision handloading is the norm. They're a straightforward choice for shooters who want honest, well-made projectiles and don't need marketing hype—just consistent balls that shoot.
| Caliber | .45 |
| Projectile Type | Round Ball (Lead) |
| Weight | 144 Grains |
| Count | 100 |
| Material | Pure Lead |
| Manufacturer Part Number | 5137 |
These are designed for .45 caliber muzzleloaders, including both traditional flintlock and percussion cap rifles as well as modern inline designs chambered in .45. Confirm your rifle's bore diameter before purchasing, as a .45 ball should be loaded with a cloth patch for traditional muzzleloaders.
Yes. At 144 grains, these lead balls are appropriate for hunting deer and similar game with a properly loaded .45 caliber muzzleloader. Performance depends on your specific rifle, powder charge, and shot placement—standard hunting practices apply.
Each box contains 100 round balls ready to load. No patches, sabots, or additional components are included; you'll need to supply your own powder, patches (if using a traditional rifle), and primers or caps.
Balls without voids, air pockets, or weight variation shoot more consistently because they behave predictably in flight. This uniformity helps produce tighter groups and more reliable hunting performance, especially when working with the variables inherent to black powder ignition.
