History: Second entry in Nosler's rebated-rim magnum family, introduced in 2015. Chambered in the Nosler Model 48, it offers 7mm Remington Magnum performance with better case geometry and higher working pressure. The 175-grain AccuBond Long Range bullet at 3,125 fps became the flagship load. Competes directly with the older 7mm STW and newer 7mm PRC for the title of best all-around long-range 7mm.
