Weatherby Select Plus 25 Wby RPM ammunition (brand part no. H25RPM117SST) loads a 117-grain Hornady SST bullet at 3,150 fps, built around Weatherby’s Rebated Precision Magnum case design. Weatherby engineered the RPM cartridge family to deliver magnum-level performance from the lighter, more compact Mark V 6-lug action, without sacrificing velocity or downrange capability. The Hornady SST (Super Shock Tip) bullet expands quickly and reliably at speed, creating a large wound channel on impact. In rifle ammunition, this load favors hunters who want magnum performance without a magnum-length rifle.
