Fort Scott Munitions® Tumble Upon Impact® (TUI®) Brush Hog 45-70 Government 300 Grain Solid Copper Spun Lead-Free – Match-Grade Centerfire Rifle Ammunition – 20-Round Box – 4570-300-SCV1
Product Description
The Fort Scott Munitions® Tumble Upon Impact® (TUI®) Brush Hog 45-70 Government 300 Grain Solid Copper Spun Ammunition (4570-300-SCV1) represents a groundbreaking milestone in non-toxic straight-wall ballistics, multi-patented terminal physics, and heavy-timber weapon staging, proudly engineered and pressure-vetted natively by defense pioneers in Fort Scott, Kansas. Explicitly engineered to provide an uncompromising, match-grade terminal stopping vector for big-game rifle hunters, wilderness protection details, and home-defense frameworks, this monolithic centerfire cartridge completely redefines traditional big-bore caliber metrics. While typical lead-core brush hunting bullets depend on conventional mushrooming or massive expansion lines that can lead to bullet fragmentation, core-jacket shedding, or off-axis deflection when clipping thick twigs, the FSM Brush Hog establishes a clean, relentless path through environmental debris to lock down absolute terminal and physical authority over your target environment.
The core technological and metallurgical superiority of this high-performance cartridge rests on its precision CNC-lathed 300-grain Solid Copper Spun (SCS) monolithic projectile. Machined from solid, premium copper rods to guarantee unparalleled geometric concentricity and zero internal weight variances, this multi-patented projectile utilizes advanced hydrostatic dynamics rather than expansion. Upon making contact with water-based organic tissue, the unique nose profile and mass distribution lines force the bullet to immediately tumble end-over-end through the target. This rapid rotational tumbling cycle rips an immense, multi-directional internal wound channel that transfers 100% of the bullet's kinetic energy directly into vital zones. Because the solid copper core does not disintegrate, break apart, or expand traditionally, it retains maximum structural weight, driving incredibly deep through tough bone matrices and thick hide layers with absolute linear precision.
The true operational triumph of this American-built rimmed hunting engine lies within its 100% lead-free environmental compliance and ultra-consistent action-cycling tolerances. Yielding a standard cartridge overall length (COAL) of 2.500 inches, the uniform bullet ogive glides seamlessly past lever-action guide ramps and single-shot blocks without catching or binding. Pushed by an optimized 44-grain charge of premium propellant, the 300-grain solid slug leaves the muzzle at a hard-hitting 1,763 feet per second (FPS) with a devastating 2,071 foot-pounds of muzzle energy. This clean-burning powder matrix optimizes gas-expansion curves while radically reducing downstream carbon soot and metal scaling inside your barrel assembly, ensuring your staging platform preserves absolute mechanical, technical, and operational uniformity across high-stress environments.

*Administrative Armorer Staging, Action Compliance Warnings & Regional Statutory Restrictions Guidance: Fort Scott Munitions TUI Brush Hog ammunition is an intensive high-mass hunting component. **CRUCIAL PLATFORM SAFETY CEILING:** Fort Scott Munitions explicitly mandates a strict structural warning—THIS AMMUNITION IS NOT FOR USE IN REVOLVERS or big-bore handguns due to specialized powder burn matrices and case configuration pressures; it is engineered strictly for modern lever-action and single-shot rifle actions in outstanding working condition. **HAZMAT SURFACE SHIPPING RESTRICTIONS:** In strict compliance with Department of Transportation (DOT) mandates, all small arms ammunition must ship exclusively via UPS Ground or FedEx Ground surface networks and is completely ineligible for air transit methods; purchasers must be a minimum of 21 years of age. Local municipal and state-level laws strictly regulate online ammunition delivery; shipments bound for California, New York, New Jersey, Illinois, Connecticut, and Massachusetts must route directly to a verified Federal Firearms Licensee (FFL) or certified commercial ammunition vendor with mandatory identity/background screening hoops. Thoroughly wash hands with soap and water immediately following any field fire or bench loading procedures to prevent physical exposure to lead dust and structural chemical residue.
Key Features
