Hornady round balls are precisely uniform in size, weight and roundness, ensuring consistent and accurate performance. They are cold-swaged from pure lead, which eliminates air pockets and voids typically found in cast balls. Additionally, the smoother, rounder surface enhances rotation and consistency. Precision-engineered - meticulously swaged to eliminate air pockets, ensuring optimal accuracy Pure lead emulates the conventional design paradigm, maintaining the integrity and authenticity of traditional architectural frameworks Consistent - exhibiting uniformity in size, weight and concentricity
