DoubleTap 357 Sig 115gr Lead-Free Tactical Ammo - 20 Rounds

The DoubleTap 357S115X delivers consistent terminal performance with lead-free construction for indoor ranges and environmentally sensitive areas. This tactical-grade ammunition combines proven powder charges with premium components to achieve reliable expansion and penetration across temperature extremes.

What Makes This Different

DoubleTap's lead-free bullet design eliminates toxic residue while maintaining the velocity and energy characteristics shooters expect from 357 Sig cartridges. The solid copper construction provides consistent weight retention through barriers, delivering approximately 15-20% deeper penetration than traditional hollow points. Factory testing shows velocities averaging 1,350 fps from 4-inch barrels with minimal velocity spread.

Key Features

• 115-grain solid copper bullet eliminates lead exposure concerns
• Optimized powder charge delivers 1,350+ fps muzzle velocity
• Temperature-stable propellant performs consistently from -20°F to 140°F
• Premium brass cases sized for reliable feeding in all 357 Sig platforms
• Boxer-primed cases support reloading for cost-conscious shooters
• 20-round boxes allow precise inventory management
• Compatible with Glock 31/32, SIG P229/P320, and other 357 Sig firearms

Field testing demonstrates reliable expansion at velocities above 1,200 fps while maintaining structural integrity through heavy clothing and intermediate barriers. Law enforcement agencies specify this load for duty use where lead-free requirements apply. The consistent powder charge produces tight velocity spreads that translate to improved accuracy at extended ranges, making it suitable for both defensive applications and precision shooting.
