Eagle Magnum lead shot contains 4.5-5% antimony for extra hardness to prevent deformation. Uniform size ensures tighter patterns downrange. Sold in 25 lb. bags.

Comparing Magnum and Chilled Lead Shot:
Chilled lead shot is slightly softer than magnum lead shot (i.e., shot that has been alloyed with higher concentrations of antimony). Many shotgunners prefer harder magnum shot for its ability to retain a spherical form better. Because chilled lead shot contains lower concentrations of antimony, which is lighter than lead, the resulting chilled shot pellet is slightly denser than magnum shot.

Magnum is harder and slightly less dense.
Chilled is softer and slightly denser.

Specifications:
Acceptable industry tolerances apply; expect slight variances in shot counts and diameters due to production differences.
