Fort Scott Munitions TUI 556x45mm NATO Rifle Ammunition Solid Copper Spun 55 Grain 20 Rounds per Box 556 055 SCV 556055SCV UPC 753677048140
Product Description
Fort Scott Munitions® 5.56x45mm NATO TUI® (SKU: 556-055-SCV / UPC: 753677048140) delivers match-grade precision and multi-patented terminal mechanics engineered specifically for duty patrol, tactical home defense, and predator/varmint hunting. Loaded with precision CNC-turned 55 Grain Solid Copper Spun (SCS®) monolithic bullets in 20-round boxes, this premium American-made cartridge delivers extreme aerodynamic consistency and devastating stopping power across modern carbine and rifle platforms.
At the center of this cartridge is Fort Scott Munitions' proprietary Solid Copper Spun (SCS®) projectile. Lathe-turned from solid copper stock, the bullet features engineered driving bands that optimize gas sealing behind the base while drastically cutting down bore friction and copper fouling. Delivering 3,426 fps of muzzle velocity and 1,433 ft-lbs of muzzle energy, the bullet flies with match-grade stability. Upon striking soft, water-based tissue, the hydrodynamic profile induces severe yaw, tumbling end-over-end (Tumble Upon Impact®) to carve massive wound cavities while maintaining nearly 100% weight retention. Because it is completely lead-free, the projectile also satisfies state non-lead hunting mandates and prevents meat contamination when harvesting game.
Every cartridge is manufactured to exacting tolerances using factory-annealed virgin brass cases that provide silky chamber cycling, positive extraction, and prolonged reload life. Driven by consistent charges of clean-burning propellant and primed with sensitive, non-corrosive small rifle Boxer primers, this 5.56 NATO load yields tight velocity spreads and exceptional shot-to-shot reliability across semi-automatic AR-15s, select-fire carbines, and precision bolt rifles alike.
*Master Ballistician Bench Notes & Range Staging Guidance:*
Chamber Compatibility & Pressure Advisory: This ammunition is loaded to full 5.56x45mm NATO pressure levels. Designed for firearms chambered in 5.56x45mm NATO or .223 Wylde. CRITICAL: Do NOT shoot NATO-pressure 5.56x45mm ammunition in older or commercial tight-throated .223 Remington chambers, as the shorter leade may cause excessive chamber pressure spikes. NEVER chamber 5.56 ammunition into a .300 AAC Blackout rifle. Monolithic copper bullets will stabilize effectively in 1:7", 1:8", and 1:9" twist barrels; verify DOPE and point-of-impact when transitioning across 10.5", 14.5", 16", and 20" barrel configurations.
- Verify the firearm chamber stamping and barrel markings match the exact 5.56x45mm NATO cartridge designation printed on the ammunition headstamp and retail box prior to staging.
- Inspect individual cartridges during magazine staging for seated primer uniformity, case neck annealing integrity, and consistent overall cartridge length (COAL: 2.245"–2.255") free of bullet setback.
- Ensure your AR-15 gas block, buffer weight (H1/H2), and action spring are properly matched for standard full-power 5.56 NATO cycling, particularly when operating suppressed.
- Verify mechanical zero and point-of-impact (POI) at 50/200 or 100 yards, noting that monolithic solid copper projectiles often demonstrate flatter trajectories and distinct POI offsets compared to standard lead-core M193 FMJ or M855 ball ammunition.
- Store remaining ammunition in a cool, dry, climate-controlled environment inside a sealed M2A1 ammunition can equipped with desiccant packs, and observe all applicable Ground HAZMAT transport guidelines.
Key Features
- Multi-Patented TUI® Monolithic Architecture: CNC-machined 55 Grain Solid Copper Spun (SCS®) projectile tumbles end-over-end in soft targets, delivering massive terminal shock channels without relying on bullet mushrooming or fragmentation.
- High-Velocity Kinetic Delivery: Produces 3,426 fps muzzle velocity and 1,433 ft-lbs muzzle energy for flat-shooting trajectories and decisive kinetic transfer on target.
- Annealed Brass & Non-Corrosive Primers: Built with premium factory-annealed reloadable brass cases and sensitive Boxer small rifle primers to guarantee smooth extraction and continuous semi-auto cycling.
- 100% Lead-Free & Indoor Range Compliant: Solid copper construction is non-magnetic, contains zero toxic lead, and complies with California CDFW non-lead regulations and indoor range safety rules.
- Convenient 20-Round Box Staging: Packed in compact 20-round boxes, ideal for staging defensive magazines, tactical patrol loadouts, or predator hunting packs.
