Underwood 357 Mag 180gr Lead Flat Nose ammunition delivers reliable, cost-effective performance for target shooting, practice, and defensive applications where lead projectiles are permitted. Designed for shooters who demand consistent velocity and accuracy without premium pricing, this 20-round per box offering serves law enforcement training ranges, civilian marksmanship programs, and handloaders seeking quality factory ammunition. The flat nose profile provides superior expansion characteristics compared to traditional round nose designs, making it suitable for both paper and steel targets.
The 180-grain lead projectile construction delivers optimal ballistic performance in the .357 Magnum platform, balancing velocity, energy retention, and controllability across standard and magnum-length barrels. Flat nose geometry increases frontal surface area upon impact, promoting more efficient energy transfer and measurable bullet expansion in soft targets—a critical distinction from conventional round nose ammunition. This projectile weight and design combination produces superior penetration and wound channel consistency, making it effective for duty carry while remaining economical enough for high-volume range sessions where shooters can validate point-of-aim without financial constraint.
Law enforcement agencies, competitive shooters, and private citizens operating .357 Magnum revolvers—including Smith & Wesson K-frame and N-frame models, Ruger GP100, and equivalent platforms—will benefit from this ammunition's reliability and performance consistency. The 20-round per box configuration offers practical logistics for both single-session training and multi-day courses, with 10 boxes per case enabling departments and ranges to maintain adequate reserves. Lead ammunition remains the preferred choice in jurisdictions prohibiting jacketed rounds on indoor ranges, making this Underwood product an essential resource for facility compliance while maintaining terminal effectiveness standards.
