The Weatherby Select Plus .240 Weatherby Magnum 72-grain Hammer Custom Solid Copper Monolithic Brass 20-round box is an ultra-high-velocity centerfire rifle cartridge engineered specifically for long-range varmint suppression, predator control, and medium game hunting. A primary failure point when pushing lightweight .243-caliber projectiles at extreme velocities is premature jacket fragmentation or bullet core separation upon initial contact, leading to shallow penetration and erratic terminal performance. Weatherby addresses these ultra-velocity limitations by pairing its belted brass casings with a precision-machined 72-grain solid copper Hammer Custom projectile, delivering structural integrity, near 100% weight retention, and predictable straight-line wound channels.
The primary technical advantage centers on the 72-grain Hammer Custom bullet design. CNC-machined from solid copper alloy, this monolithic projectile eliminates jacket-and-core construction, thereby preventing bullet breakup even under high impact stress and hydraulic pressure. The solid copper geometry is engineered with optimized driving bands to minimize barrel friction, balance gas seals, and improve shot-to-shot consistency. Upon impact, the bullet undergoes controlled terminal expansion without losing mass, driving deep through tissue and bone to maximize energy transfer.
Launching its 72-grain monolithic copper projectile at a blistering factory-rated 3,700 FPS muzzle velocity, this Select Plus loading fully leverages the massive case capacity and pressure profile of the .240 Weatherby Magnum. Assembled using Weatherby's premium belted brass casings alongside clean-burning powders and non-corrosive Boxer primers, the cartridge guarantees smooth feeding, positive headspace alignment, and uniform pressure curves across magnum bolt-action platforms. It serves as an elite, flat-shooting choice for long-range coyotes, pronghorn, whitetail deer, and open-country varmints.
Key Benefits
