Weatherby loads its .25 WBY RPM rifle ammunition (brand part no. B25RPM117LRX) with a 117-grain Barnes LRX bullet, pairing the company’s Rebated Precision Magnum cartridge design with a monolithic copper projectile built for extended-range hunting. Weatherby engineered the RPM line to deliver magnum-class velocity out of a short-action rifle, giving hunters a compact, lighter platform without giving up downrange performance. The Barnes LRX (Long-Range X) bullet uses a polymer tip and boat-tail profile to hold velocity at distance while its all-copper construction retains nearly all of its weight through impact for deep, controlled penetration. For hunters loading up on rifle ammunition for a short-action magnum, this factory pairing is built specifically for the RPM platform.
