Hardball Bullet Alloy – 2 lb Ingots

92% Lead | 6% Antimony | 2% Tin | Approx. 16 BHN

Rock Shot Products Hardball Bullet Alloy is formulated with 92% lead, 6% antimony, and 2% tin, providing a versatile balance of hardness, strength, and castability for bullet casters.

With an estimated hardness of approximately 16 BHN, Hardball is considerably harder than pure lead while remaining a practical general-purpose alloy for a wide variety of bullet-casting applications.

Our Hardball Bullet Alloy is supplied in convenient approximately 2 lb ingots, making it easy to handle, portion, melt, and incorporate into your casting operation.

Sold as individual approximately 2 lb ingots with a minimum purchase of 5 ingots (approximately 10 lb total).

A Versatile Bullet Casting Alloy

The combination of 6% antimony and 2% tin provides increased hardness compared with softer lead alloys while maintaining useful casting characteristics.

Hardball Alloy is well suited for casters looking for a dependable, general-purpose alloy for applications where greater hardness and deformation resistance are desired.

Common uses include:

• General bullet casting
• Handgun bullet casting
• Rifle bullet casting where an alloy of this hardness is appropriate
• Custom alloy blending
• Hardening softer lead alloys
• General metal casting and alloy experimentation

Convenient 2 lb Ingot Size

Although the minimum purchase is 5 ingots, each individual ingot weighs approximately 2 lb. The smaller ingot format makes the alloy easier to handle, weigh, portion, and melt.

Instead of working with one large block of alloy, casters can use individual ingots as needed and more easily manage the amount of alloy going into each melt.

Minimum Purchase

This product has a minimum purchase of 5 ingots, representing approximately 10 lb of Hardball Bullet Alloy.

The smaller individual ingot size provides convenient handling and portioning while the 5-ingot minimum allows Rock Shot Products to offer this alloy at competitive direct pricing.

Important Alloy Information

Actual hardness and finished casting properties can vary based on alloy composition, cooling rate, casting conditions, heat treatment, and other processing variables.

The approximately 16 BHN figure is an estimate and should not be interpreted as a certified hardness measurement for every ingot or finished casting.
