RPM stands for rebated precision magnum a modern case design built to maximize performance in the lightweight Mark V 6 lug action. The idea is simple create a magnum level cartridge that fits in a lighter more compact rifle without sacrificing velocity or downrange capability.
Hammer Custom
Hammer Bullets™ are turned on a CNC lathe and use a unique solid copper blend that is designed for maximum terminal performance. Each bullet is weighed and micrometer measured as it is produced. The result is an incredibly consistent product with unparalleled quality control. The hollow point design initiates expansion upon impact shedding petals immediately with the remainder of the bullet staying intact with a blunt front for optimal wound channel. All Hammer Custom Bullets are designed to optimize Weatherby’s flat shooting cartridges.
