Berry’s 40 Cal 180gr RS

Berry’s 40 Cal 180gr RS is a plated bullet component built for handloaders crafting dependable .40 S&W and 10mm Auto ammunition. Featuring a round shoulder (RS) profile and a 180-grain weight, this bullet provides smooth feeding and consistent performance across a wide range of semi-automatic platforms. It is sold as a bullet component only—not factory-loaded ammunition—and is designed for target practice, duty training, and recreational use.

Each projectile begins with a swaged lead core, electroplated in copper to its final weight, then re-struck for precise geometry. This process ensures tight diameter and weight tolerances, supporting uniform ignition and trajectory. The bullet measures .400″ in diameter with a bullet overall length of .575″, and it is intended for cartridges seated to 1.125″ for .40 S&W and 1.250″ for 10mm Auto. The fully encapsulated design eliminates exposed lead, making it safe for indoor range environments and minimizing barrel fouling over extended use.

The RS profile is engineered to offer dependable chambering and feeding in striker-fired pistols and other modern semi-auto platforms. Its consistent shape supports clean cycling in double-stack magazines and ensures alignment with common barrel types. The 180gr weight balances recoil control with retained energy, making it suitable for use in both defensive training and structured practice environments.

Berry’s specifies a maximum velocity of 1,250 feet per second for this bullet. Maintaining velocities within this range ensures plating integrity and consistent ballistic performance. Load data for similar 180gr plated or jacketed bullets should be referenced, and a taper or roll crimp may be applied depending on case type and application. Over-crimping should be avoided to prevent deformation of the plated exterior and accuracy degradation.

Berry’s 40 Cal 180gr RS is an ideal choice for reloaders seeking a clean-shooting, cost-effective alternative to traditional jacketed bullets. With its precise construction and reliable feeding profile, it serves as a trusted component for .40 S&W and 10mm handloads used in competition, qualification drills, or general-purpose range work.
