Speer Muzzleloader Round Lead Balls .451" 137 gr MZRB 100/ct

These .451" round balls are swaged from pure lead, with Speer using a process meant to keep the balls uniform and free of voids or air pockets. That matters in a muzzleloader because consistency in the projectile is part of what keeps loading and performance predictable.

The smooth, round surface is the other practical piece here. It’s there to help the ball rotate more consistently, which is the sort of detail muzzleloader shooters pay attention to when they want repeatable results from a round-ball setup.
