Hsm 7mm Rum 140gr Sbt - Sierra Game King 20rd 20bx/cs

The HSM 7mm RUM 140gr SBT Sierra Game King ammunition represents a purpose-built hunting round engineered for long-range precision and reliable terminal performance. Designed for shooters who demand accuracy at extended distances, this cartridge delivers the velocity and energy retention necessary for ethical, one-shot harvesting of medium to large game. The 7mm Remington Ultra Magnum platform provides the ballistic foundation that serious hunters and precision rifle competitors depend on when maximum range capability and flat trajectory are non-negotiable.

Each round pairs HSM's carefully formulated brass and propellant charge with Sierra's GameKing bullet—a time-tested spitzer boat-tail design that combines controlled expansion with exceptional structural integrity. The 140-grain bullet weight balances velocity retention and wind drift reduction, crucial factors in variable field conditions. Sierra's boat-tail configuration reduces drag coefficient, translating to flatter trajectories and more consistent energy delivery downrange. The controlled-expansion design ensures the bullet opens reliably on impact while maintaining adequate penetration, preventing over-expansion that leads to meat damage or inadequate penetration on angled shots.

This ammunition suits bolt-action rifles chambered in 7mm RUM, particularly those equipped with quality optics and capable of handling magnum recoil. Hunters pursuing elk, mule deer, and similar-sized game at 300+ yards will benefit from the flat shooting characteristics and retained velocity. Each box contains 20 rounds, allowing for adequate practice and field load development. Proper firearm maintenance and adherence to manufacturer load specifications ensure consistent performance and safety across all shooting conditions.
