HSM (part no. 7RUM-8-N) loads this 7mm Remington Ultra Magnum round with a 140-grain Sierra GameKing bullet, a spitzer boat-tail jacketed soft point built for accuracy and consistent terminal performance on big game. HSM has long paired its ammunition with Sierra’s proven GameKing bullets, and the lighter 140-grain weight in this 7mm Remington Ultra Magnum case pushes velocity higher than the 160-grain option for an even flatter trajectory. The case is reloadable for shooters who process their own ammunition. In rifle ammunition built around a proven bullet in a genuine magnum case, this is a flat-shooting hunting load.
