Bullet Mould / Minie Ball
RCBS Minie Ball Bullet Moulds are constructed of the best quality iron. The blocks are ground to achieve an exact tolerance. The locating pins are case hardened to limit wear and to provide permanent alignment for the bullet cavities. Bullet cavities are machined to form a perfect match. The Sprue cutter is a solid steel plate that has been machined to hold firmly against the mould block with an adjustable wave washer. RCBS and Lyman 2 cavity handles will normally fit RCBS moulds. Bullet mould handles not included.


Most are Double Cavity design except where noted.
+ Single Cavity Mould

HISTORICAL SIGNIFICANCE: During the Civil War the North and South used a great variety of small arms ammunition, but the type most used was the minie ball. Prior to the development of the minie ball, rifles were not used in combat due to the difficulty in loading. The ammunition used by rifles was the same diameter as the barrel in order for the bullet to engage the groves of the rifled barrel. As a result the ball had to be forced into the barrel. The minie ball, originally designed by Captain Claude-Etienne Minie of France [1849] and improved on by manufacturers in the United States, changed warfare. Since the minie ball was smaller than the diameter of the barrel, it could be loaded quickly by dropping the bullet down the barrel. This conical lead bullet had two or three grooves and a conical cavity in its base. The gases, formed by the burning of powder once the firearm was fired, expanded the base of the bullet so that it engaged the rifling in the barrel. Thus, rifles could be loaded quickly and yet fired accurately.

California Prop. 65 Warning: Melting lead and casting lead objects (with these products) will expose you and others in the area to lead, which is known to cause birth defects, other reproductive harm, and cancer.
