Berry’s 458 SOCOM 350gr RS

Berry’s 458 SOCOM 350gr RS is a plated bullet component engineered for precision handloading in the powerful 458 SOCOM cartridge. This 350-grain Round Shoulder (RS) projectile provides reliable feeding, clean shooting, and deep-penetrating performance in both semi-automatic and bolt-action rifles chambered in 458 SOCOM. It is sold as a bullet component only—not factory-loaded ammunition—making it ideal for reloaders developing subsonic or full-power hunting and tactical loads.

The bullet is constructed from a swaged lead core and fully encapsulated in electroplated copper, then re-struck to final dimensions for uniform diameter and weight. Measuring .899″ in bullet overall length, it is designed for seating to a cartridge overall length of approximately 1.985″, fully compatible with AR-15 pattern magazines and standard Berry’s 458 SOCOM chambers. The copper-plated exterior prevents lead exposure and minimizes barrel fouling, making it suitable for indoor ranges and high-volume shooting.

The round shoulder profile ensures smooth feeding and consistent chambering, especially in semi-automatic rifles. Its heavy 350gr weight provides excellent momentum and terminal energy, making it a strong performer for hunting medium to large game or for suppressed subsonic applications. This bullet is optimized for reliable cycling and consistent accuracy across various twist rates common to the 458 SOCOM platform.

Berry’s specifies a maximum safe velocity of 2,000 feet per second. Staying within this velocity threshold helps preserve the bullet’s plating integrity and prevents core-jacket separation. Load data for cast or jacketed bullets of similar weight and profile may be used. Either taper or roll crimps are compatible, but over-crimping must be avoided to maintain structural integrity and flight consistency.

Berry’s 458 SOCOM 350gr RS gives reloaders a versatile, hard-hitting solution for high-performance 458 SOCOM handloads. Its fully plated design, re-strike precision, and reliable round shoulder geometry make it an excellent choice for tactical shooting, game hunting, or suppressed applications requiring consistent, clean, and safe performance in a heavy-caliber AR-15 platform.
