Rim Rock Bullets is a family-owned and operated ammunition manufacturer renowned for producing high-quality cast lead bullets. With a commitment to craftsmanship and customer service, the company takes a hands-on approach to every aspect of its operations—from production to personal communication. Owners Frank, Susan, and Frankie Brown pride themselves on treating customers like family, ensuring responsive service and maintaining consistent stock availability.

What sets Rim Rock Bullets apart is their dedication to precision casting and material quality. Each bullet is made from virgin lead alloy, carefully mixed with optimal amounts of tin and antimony for enhanced hardness, consistency, and accuracy. By sourcing lead in massive quantities—60,000 pounds at a time—the company ensures every batch maintains the same reliable composition, resulting in bullets that perform predictably shot after shot.

The manufacturing process emphasizes uniformity and consistency. Instead of alternating between calibers, Rim Rock dedicates production runs to a single bullet type at a time. For example, a .38/.357 158 grain SWC bullet might be produced on four machines for ten consecutive days—yielding more than 1 million identical bullets. This method ensures tight tolerances and consistent performance, making Rim Rock Bullets a trusted choice for target shooters, hunters, and reloaders alike.

With a focus on accuracy, availability, and exceptional service, Rim Rock Bullets continues to earn the loyalty of shooters across the United States. Their motto, "We are happy when our customers are happy," reflects a company culture deeply rooted in integrity, reliability, and customer satisfaction.
