The Weatherby Select Plus .300 Weatherby Magnum 170-grain Hammer Lead-Free Solid Copper Brass 20-round box is a top-tier centerfire rifle cartridge engineered specifically for harvesting elk, moose, mule deer, and heavy big game at extended downrange distances. A primary friction point when shooting extreme-velocity magnum hunting cartridges is jacket-core separation and violent fragmentation upon target contact, which severely limits penetration depth through heavy hide and shoulder bone. Weatherby addresses these structural and environmental compliance challenges by pairing premium reloadable Norma brass cases with the CNC-lathe-turned monolithic solid-copper Hammer bullet, delivering maximum mass retention, ultra-flat trajectories, and deep linear penetration.
The primary technical advantage lies in the single-piece CNC-machined copper bullet geometry, paired with a 0.480 G1 ballistic coefficient. Free from internal lead-core bonding flaws or material voids, the monolithic copper construction allows the projectile to withstand ultra-high impact velocities without disintegrating. Upon target contact, the engineered hollow-point cavity triggers controlled expansion into sharp copper petals to deliver immediate energy transfer, while the solid copper rear shank retains mass to drive deep through tough tissue and vital zones.
Launching its 170-grain solid copper projectile at a blistering 3,300 FPS, this Weatherby Select Plus loading takes full advantage of the high-capacity .300 Wby Mag casing to achieve exceptional kinetic energy transfer and minimum holdover at extended ranges. Assembled using match-grade reloadable Norma brass cases, clean-burning propellants, and non-corrosive Boxer primers, it ensures uniform chamber pressure, reduced copper fouling, and smooth cycling across bolt-action Weatherby Magnum rifles. It is an outstanding selection for western mountain hunts, open-country big game pursuit, and lead-free zone compliance.
