The Weatherby Mark V Accumark (brand part no. MAM01N300PR8B) is a bolt-action rifle chambered in .300 PRC and built around Weatherby’s flagship Mark V action for hunters and long-range shooters who want serious reach without giving up reliability. A 28-inch fluted stainless barrel is cut with a fast 1:10-inch twist to stabilize the heavy, high-BC bullets .300 PRC is known for, while the black synthetic stock shrugs off rain and rough field handling. An AccuBrake ST muzzle device keeps recoil manageable so shooters can spot their own hits at distance, and an adjustable trigger rounds out a rifle built for serious precision work.
