Berry’s 40 Cal 180gr RN

Berry’s 40 Cal 180gr RN is a plated bullet component crafted for handloaders building ammunition for .40 S&W and 10mm Auto platforms. Weighing 180gr, this round-nose (RN) projectile delivers consistent performance and reliable feeding in a wide variety of semi-automatic pistols and pistol-caliber carbines. It is a bullet component only, not loaded ammunition, making it ideal for custom reloads tailored to practice, training, or competitive shooting applications.

This bullet features a swaged lead core electroplated with copper and finished through a re-strike process to ensure uniform diameter and consistent weight. The result is a fully encapsulated projectile with no exposed lead, which supports clean shooting and makes it safe for use in indoor ranges. Measuring approximately .401 inches in diameter and .596 inches in overall length, the 40 Cal 180gr RN seats and cycles well in firearms chambered for both .40 S&W and 10mm Auto.

The round-nose profile is engineered for smooth chambering and reliable feeding in various platforms, including striker-fired pistols and traditional hammer-fired handguns. This geometry also promotes accuracy across a wide velocity range, with Berry’s recommending a maximum velocity of 1,250 feet per second. Staying within this range helps preserve the plated jacket and prevents separation or deformation under pressure.

Handloaders using this bullet can apply standard data for jacketed or cast 180gr bullets. It works well with common handgun powders and performs reliably with both taper and light roll crimps. Care should be taken to avoid over-crimping, which could compromise the plated surface. Ideal overall cartridge lengths are approximately 1.125 inches for .40 S&W and 1.250 inches for 10mm Auto, depending on platform and magazine compatibility.

Berry’s 40 Cal 180gr RN is a cost-effective, clean-shooting solution for high-volume reloaders who demand consistent performance without the expense of traditional jacketed bullets. Its plated construction offers reduced barrel fouling, smoother shooting, and reliable function in all standard .40 caliber and 10mm firearms. Whether used for range sessions, tactical training, or IDPA and USPSA competitions, this bullet provides the accuracy and cycling reliability reloaders require.
