The Weatherby Select Plus 7mm Weatherby Magnum 140-grain Barnes Tipped Triple-Shock X (TTSX) Monolithic Solid Copper Brass 20-round box is a premier magnum centerfire rifle cartridge engineered specifically for harvesting elk, mule deer, whitetail deer, and pronghorn at extended ranges where flat trajectories, extreme impact velocities, and deep penetration are required. A common friction point with traditional lead-core bullets at high magnum velocities is jacket-core separation and fragmentation, which degrades structural mass and limits penetration depth. Weatherby resolves these terminal performance limitations by pairing its precision belted brass cases with the 100% solid copper Barnes TTSX projectile, delivering near-total weight retention and barrier-blind structural integrity under extreme impact stress.
The primary technical advantage relies on the single-piece monolithic copper body combined with a re-engineered nose cavity and streamlined polymer tip. Designed to eliminate lead fragmentation variables, the solid copper construction enables the bullet to retain virtually 100% of its weight as it drives through tough hide and heavy shoulder bone. Upon impact, the blue polymer tip drives rearward into the nose cavity to mechanically trigger rapid, four-petal hydraulic expansion, creating a wide permanent wound channel while the streamlined ogive cuts through crosswinds for flat downrange trajectories.
Launching its 140-grain solid copper bullet at a blistering 3,250 FPS, this Weatherby Select Plus load provides an exceptionally flat downrange flight path, reduced time-of-flight, and massive kinetic energy transfer. Assembled using premium reloadable Norma/Weatherby belted brass cases, clean-burning propellants, and non-corrosive Boxer primers, it guarantees uniform chamber pressure, tight velocity tolerances, and positive extraction in bolt-action rifles chambered in 7mm Weatherby Magnum. It is a world-class selection for western mountain hunting, open-country big game pursuit, and lead-restricted hunting zones.
