Speer Bullets 5131 Muzzleloader 45 Cal Black Powder Lead Ball 133 GR - 100 Pack

Speer 45 caliber muzzleloader lead balls are purpose-built for traditional black powder shooting and modern muzzleloading rifles alike. These 133-grain pure lead round balls come as a 100-pack, offering consistent supply for regular range work or hunting seasons. Speer manufactures them using a controlled swaging process designed to eliminate voids and air pockets that can compromise accuracy—a detail that matters when you're relying on uniform projectiles for repeatable performance downrange.

The smooth, spherical surface of each ball promotes even rotation as it engages the rifling, supporting the accuracy and consistency that serious muzzleloaders demand. Whether you're shooting a traditional caplock rifle, an inline hunting gun, or participating in black powder competitions, having a reliable supply of uniform lead balls takes the guesswork out of load development and lets you focus on shot placement.

A 100-pack of 45-caliber balls is a practical volume for hunters and range shooters who cycle through their ammunition regularly. Speer's reputation in bullet manufacturing carries over to their muzzleloading line—these aren't commodity roundballs cut from inferior processes, but ammunition built to exacting standards.
