TR&Z Range Master 5.56 NATO 55gr FMJ BT Ammo 500 Rounds (4x125)

The TR&Z Range Master 5.56x45mm NATO ammunition provides reliable performance for extended training sessions and competitive shooting. This bulk package contains 500 rounds of 55-grain full metal jacket boat tail projectiles, packaged in four boxes of 125 rounds each for convenient storage and transport.

What Makes This Different

The Range Master line emphasizes consistency and value for high-volume shooters. Each cartridge features precision-manufactured brass cases and carefully selected powder charges that deliver uniform velocities shot after shot. The boat tail design reduces drag and maintains stability downrange, while the full metal jacket construction ensures reliable feeding in semi-automatic platforms.

Key Features

• 55-grain full metal jacket boat tail projectiles for consistent ballistic performance
• NATO specification brass cases withstand multiple reloading cycles
• Non-corrosive Boxer primers ensure reliable ignition
• Muzzle velocity approximately 3,240 fps from 20-inch barrel
• Compatible with .223 Remington and 5.56 NATO chambered rifles

Range testing demonstrates consistent accuracy suitable for training drills and competitive events. The boat tail configuration maintains velocity better than flat-base alternatives, extending effective range for precision applications. Weather-resistant packaging protects ammunition during transport and storage, while the moderate powder charge produces manageable recoil for extended shooting sessions.
