The Hornady Outfitter .270 Winchester Short Magnum (WSM) 130-grain Monolithic CX (Copper Alloy eXpanding) Lead-Free Nickel 20-round box is a premier centerfire rifle hunting cartridge engineered specifically for backcountry big game hunting, elk, mule deer, whitetail, and pronghorn in harsh, high-moisture environments and lead-restricted zones. A primary failure point when firing standard hunting ammunition in extreme weather is jacket-core separation upon bone contact and moisture intrusion into the case, which can cause erratic terminal failure or misfires. Hornady completely resolves these vulnerabilities by pairing a solid copper-alloy CX bullet with waterproof, sealed nickel-plated brass cases for total environmental and structural reliability.
The technical advantage focuses on mass-driven deep penetration paired with heat-resistant aerodynamic stability. Launching its 130-grain monolithic CX projectile at a blistering muzzle velocity of 3,150 FPS, this short-action magnum load produces exceptionally flat trajectories and high downrange kinetic energy delivery. Mechanically, the CX bullet is machined from a single piece of copper alloy, eliminating core separation to retain over 95% of its original weight through dense tissue and bone. The heat-resistant Heat Shield polymer tip resists aerodynamic melting in flight to maintain its high 0.403 G1 Ballistic Coefficient (BC), while shank relief grooves lower barrel friction, reduce metal fouling, and maintain high velocity.
Slinging its 130-grain CX bullet at 3,150 FPS, this specialized .270 WSM cartridge is optimized for smooth, non-binding mechanical operation across modern short-action bolt-action hunting rifles. Assembled in premium nickel-plated reloadable brass cases featuring sealed case mouths and primers, it actively repels water and prevents internal powder contamination during multi-day backcountry downpours. The slick nickel plating lowers chamber friction for effortless loading and positive bolt extraction in freezing high-altitude conditions.
Key Benefits
- Solid Monolithic CX Copper Alloy Construction: Single-piece lead-free projectile retains over 95% weight for crushing bone-deep penetration.
- Heat Shield Polymer Tip (0.403 G1 BC): Resists aerodynamic heating to preserve shape, delivering flat trajectories and tight long-range grouping.
- Waterproof Sealed Nickel-Plated Brass: Sealants at the primer and case mouth prevent moisture ingress while nickel plating eliminates corrosion.
- 100% Non-Toxic Lead-Free Design: Fully compliant with non-toxic hunting mandates without sacrificing bullet weight retention or velocity.
