Weatherby 7mm PRC 177gr Hammer Custom ammunition (brand part no. M7PRC177HCB) sends a 177-grain monolithic copper bullet downrange at 2950 feet per second, pairing the modern 7mm PRC cartridge with a purpose-built hunting bullet. The Hammer Custom bullet is machined from solid copper rather than a traditional lead core, giving it controlled expansion and reliable structural integrity on impact much like other monolithic hunting bullets on the market. That lead-free construction also keeps the load usable in areas that restrict traditional lead ammunition for hunting. For big-game hunters who want flat-shooting 7mm PRC performance backed by a bullet built to hold together, this Weatherby load is a serious option.
