Underwood 458 Socom 300gr Jhp - 20rd 10bx/cs

The Underwood 458 Socom 300gr JHP ammunition delivers serious stopping power for shooters who demand terminal performance from a pistol-caliber rifle platform. Designed specifically for the .458 Socom cartridge, this load combines controlled expansion with deep penetration—critical characteristics for duty, defense, and hunting applications where reliability under pressure matters. Each box contains 20 rounds across a convenient 10-box case format, making it practical for shooters who prioritize consistent supply without excessive bulk storage.

Underwood's 300-grain jacketed hollow point projectile is engineered for controlled expansion upon impact while maintaining structural integrity through intermediate barriers—a hallmark of professional-grade ammunition. The .458 Socom cartridge itself operates at pressures optimized for reliable function in AR-pattern rifles, and Underwood's precision loading ensures consistent velocity and accuracy shot to shot. This weight-forward design maximizes momentum delivery, particularly important in the .458 platform where terminal ballistics are the primary advantage over conventional intermediate cartridges.

Law enforcement, military end-users, and civilian shooters running .458 Socom uppers or complete rifles will appreciate ammunition that performs as intended downrange. The 300-grain hollow point configuration balances velocity retention with rapid energy transfer, making this round suitable for close-to-intermediate range engagements where the .458 platform excels. Proper storage in a cool, dry environment preserves the integrity of both projectile and primer components across extended inventory cycles.
